[1] These helpers provide +the transition layer between the DRM core infrastructure and the fbdev +driver interface. Create a new DRM driver on top of the fbconv helpers, +copy over the fbdev driver, and hook it up to the DRM code. Examples for +several fbdev drivers are available at [1] and a tutorial of this process +available at [2].

This means that each frame is decoded independently +of any previous and future frames, and that the client is responsible for +maintaining the decoding state and providing it to the decoder with each +decoding request. This is in contrast to the stateful video decoder interface, +where the hardware and driver maintain the decoding state and all the client +has to do is to provide the raw encoded stream and dequeue decoded frames in +display order. + +This section describes how user-space ("the client") is expected to communicate +with stateless decoders in order to successfully decode an encoded stream. +Compared to stateful codecs, the decoder/client sequence is simpler, but the +cost of this simplicity is extra complexity in the client which is responsible +for maintaining a consistent decoding state. + +Stateless decoders make use of the :ref:`media-request-api`. A stateless +decoder must expose the ``V4L2_BUF_CAP_SUPPORTS_REQUESTS`` capability on its +``OUTPUT`` queue when :c:func:`VIDIOC_REQBUFS` or :c:func:`VIDIOC_CREATE_BUFS` +are invoked. + +Depending on the encoded formats supported by the decoder, a single decoded +frame may be the result of several decode requests (for instance, H.264 streams +with multiple slices per frame). Decoders that support such formats must also +expose the ``V4L2_BUF_CAP_SUPPORTS_M2M_HOLD_CAPTURE_BUF`` capability on their +``OUTPUT`` queue. + +Querying capabilities +===================== + +1. To enumerate the set of coded formats supported by the decoder, the client + calls :c:func:`VIDIOC_ENUM_FMT` on the ``OUTPUT`` queue. + + * The driver must always return the full set of supported ``OUTPUT`` formats, + irrespective of the format currently set on the ``CAPTURE`` queue. + + * Simultaneously, the driver must restrain the set of values returned by + codec-specific capability controls (such as H.264 profiles) to the set + actually supported by the hardware. + +2. To enumerate the set of supported raw formats, the client calls + :c:func:`VIDIOC_ENUM_FMT` on the ``CAPTURE`` queue. + + * The driver must return only the formats supported for the format currently + active on the ``OUTPUT`` queue. + + * Depending on the currently set ``OUTPUT`` format, the set of supported raw + formats may depend on the value of some codec-dependent controls. + The client is responsible for making sure that these controls are set + before querying the ``CAPTURE`` queue. Failure to do so will result in the + default values for these controls being used, and a returned set of formats + that may not be usable for the media the client is trying to decode. + +3. The client may use :c:func:`VIDIOC_ENUM_FRAMESIZES` to detect supported + resolutions for a given format, passing desired pixel format in + :c:type:`v4l2_frmsizeenum`'s ``pixel_format``. + +4. Supported profiles and levels for the current ``OUTPUT`` format, if + applicable, may be queried using their respective controls via + :c:func:`VIDIOC_QUERYCTRL`. + +Initialization +============== + +1. Set the coded format on the ``OUTPUT`` queue via :c:func:`VIDIOC_S_FMT`. + + * **Required fields:** + + ``type`` + a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``. + + ``pixelformat`` + a coded pixel format. + + ``width``, ``height`` + coded width and height parsed from the stream. + + other fields + follow standard semantics. + + .. note:: + + Changing the ``OUTPUT`` format may change the currently set ``CAPTURE`` + format. The driver will derive a new ``CAPTURE`` format from the + ``OUTPUT`` format being set, including resolution, colorimetry + parameters, etc. If the client needs a specific ``CAPTURE`` format, + it must adjust it afterwards. + +2. Call :c:func:`VIDIOC_S_EXT_CTRLS` to set all the controls (parsed headers, + etc.) required by the ``OUTPUT`` format to enumerate the ``CAPTURE`` formats. + +3. Call :c:func:`VIDIOC_G_FMT` for ``CAPTURE`` queue to get the format for the + destination buffers parsed/decoded from the bytestream. + + * **Required fields:** + + ``type`` + a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``. + + * **Returned fields:** + + ``width``, ``height`` + frame buffer resolution for the decoded frames. + + ``pixelformat`` + pixel format for decoded frames. + + ``num_planes`` (for _MPLANE ``type`` only) + number of planes for pixelformat. + + ``sizeimage``, ``bytesperline`` + as per standard semantics; matching frame buffer format. + + .. note:: + + The value of ``pixelformat`` may be any pixel format supported for the + ``OUTPUT`` format, based on the hardware capabilities. It is suggested + that the driver chooses the preferred/optimal format for the current + configuration. For example, a YUV format may be preferred over an RGB + format, if an additional conversion step would be required for RGB. + +4. *[optional]* Enumerate ``CAPTURE`` formats via :c:func:`VIDIOC_ENUM_FMT` on + the ``CAPTURE`` queue. The client may use this ioctl to discover which + alternative raw formats are supported for the current ``OUTPUT`` format and + select one of them via :c:func:`VIDIOC_S_FMT`. + + .. note:: + + The driver will return only formats supported for the currently selected + ``OUTPUT`` format and currently set controls, even if more formats may be + supported by the decoder in general. + + For example, a decoder may support YUV and RGB formats for + resolutions 1920x1088 and lower, but only YUV for higher resolutions (due + to hardware limitations). After setting a resolution of 1920x1088 or lower + as the ``OUTPUT`` format, :c:func:`VIDIOC_ENUM_FMT` may return a set of + YUV and RGB pixel formats, but after setting a resolution higher than + 1920x1088, the driver will not return RGB pixel formats, since they are + unsupported for this resolution. + +5. *[optional]* Choose a different ``CAPTURE`` format than suggested via + :c:func:`VIDIOC_S_FMT` on ``CAPTURE`` queue. It is possible for the client to + choose a different format than selected/suggested by the driver in + :c:func:`VIDIOC_G_FMT`. + + * **Required fields:** + + ``type`` + a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``. + + ``pixelformat`` + a raw pixel format. + + ``width``, ``height`` + frame buffer resolution of the decoded stream; typically unchanged from + what was returned with :c:func:`VIDIOC_G_FMT`, but it may be different + if the hardware supports composition and/or scaling. + + After performing this step, the client must perform step 3 again in order + to obtain up-to-date information about the buffers size and layout. + +6. Allocate source (bytestream) buffers via :c:func:`VIDIOC_REQBUFS` on + ``OUTPUT`` queue. + + * **Required fields:** + + ``count`` + requested number of buffers to allocate; greater than zero. + + ``type`` + a ``V4L2_BUF_TYPE_*`` enum appropriate for ``OUTPUT``. + + ``memory`` + follows standard semantics. + + * **Return fields:** + + ``count`` + actual number of buffers allocated. + + * If required, the driver will adjust ``count`` to be equal or bigger to the + minimum of required number of ``OUTPUT`` buffers for the given format and + requested count. The client must check this value after the ioctl returns + to get the actual number of buffers allocated. + +7. Allocate destination (raw format) buffers via :c:func:`VIDIOC_REQBUFS` on the + ``CAPTURE`` queue. + + * **Required fields:** + + ``count`` + requested number of buffers to allocate; greater than zero. The client + is responsible for deducing the minimum number of buffers required + for the stream to be properly decoded (taking e.g. reference frames + into account) and pass an equal or bigger number. + + ``type`` + a ``V4L2_BUF_TYPE_*`` enum appropriate for ``CAPTURE``. + + ``memory`` + follows standard semantics. ``V4L2_MEMORY_USERPTR`` is not supported + for ``CAPTURE`` buffers. + + * **Return fields:** + + ``count`` + adjusted to allocated number of buffers, in case the codec requires + more buffers than requested. + + * The driver must adjust count to the minimum of required number of + ``CAPTURE`` buffers for the current format, stream configuration and + requested count. The client must check this value after the ioctl + returns to get the number of buffers allocated. + +8. Allocate requests (likely one per ``OUTPUT`` buffer) via + :c:func:`MEDIA_IOC_REQUEST_ALLOC` on the media device. + +9. Start streaming on both ``OUTPUT`` and ``CAPTURE`` queues via + :c:func:`VIDIOC_STREAMON`. + +Decoding +======== + +For each frame, the client is responsible for submitting at least one request to +which the following is attached: + +* The amount of encoded data expected by the codec for its current + configuration, as a buffer submitted to the ``OUTPUT`` queue. Typically, this + corresponds to one frame worth of encoded data, but some formats may allow (or + require) different amounts per unit. +* All the metadata needed to decode the submitted encoded data, in the form of + controls relevant to the format being decoded. + +The amount of data and contents of the source ``OUTPUT`` buffer, as well as the +controls that must be set on the request, depend on the active coded pixel +format and might be affected by codec-specific extended controls, as stated in +documentation of each format. + +If there is a possibility that the decoded frame will require one or more +decode requests after the current one in order to be produced, then the client +must set the ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag on the ``OUTPUT`` +buffer. This will result in the (potentially partially) decoded ``CAPTURE`` +buffer not being made available for dequeueing, and reused for the next decode +request if the timestamp of the next ``OUTPUT`` buffer has not changed. + +A typical frame would thus be decoded using the following sequence: + +1. Queue an ``OUTPUT`` buffer containing one unit of encoded bytestream data for + the decoding request, using :c:func:`VIDIOC_QBUF`. + + * **Required fields:** + + ``index`` + index of the buffer being queued. + + ``type`` + type of the buffer. + + ``bytesused`` + number of bytes taken by the encoded data frame in the buffer. + + ``flags`` + the ``V4L2_BUF_FLAG_REQUEST_FD`` flag must be set. Additionally, if + we are not sure that the current decode request is the last one needed + to produce a fully decoded frame, then + ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` must also be set. + + ``request_fd`` + must be set to the file descriptor of the decoding request. + + ``timestamp`` + must be set to a unique value per frame. This value will be propagated + into the decoded frame's buffer and can also be used to use this frame + as the reference of another. If using multiple decode requests per + frame, then the timestamps of all the ``OUTPUT`` buffers for a given + frame must be identical. If the timestamp changes, then the currently + held ``CAPTURE`` buffer will be made available for dequeuing and the + current request will work on a new ``CAPTURE`` buffer. + +2. Set the codec-specific controls for the decoding request, using + :c:func:`VIDIOC_S_EXT_CTRLS`. + + * **Required fields:** + + ``which`` + must be ``V4L2_CTRL_WHICH_REQUEST_VAL``. + + ``request_fd`` + must be set to the file descriptor of the decoding request. + + other fields + other fields are set as usual when setting controls. The ``controls`` + array must contain all the codec-specific controls required to decode + a frame. + + .. note:: + + It is possible to specify the controls in different invocations of + :c:func:`VIDIOC_S_EXT_CTRLS`, or to overwrite a previously set control, as + long as ``request_fd`` and ``which`` are properly set. The controls state + at the moment of request submission is the one that will be considered. + + .. note:: + + The order in which steps 1 and 2 take place is interchangeable. + +3. Submit the request by invoking :c:func:`MEDIA_REQUEST_IOC_QUEUE` on the + request FD. + + If the request is submitted without an ``OUTPUT`` buffer, or if some of the + required controls are missing from the request, then + :c:func:`MEDIA_REQUEST_IOC_QUEUE` will return ``-ENOENT``. If more than one + ``OUTPUT`` buffer is queued, then it will return ``-EINVAL``. + :c:func:`MEDIA_REQUEST_IOC_QUEUE` returning non-zero means that no + ``CAPTURE`` buffer will be produced for this request. + +``CAPTURE`` buffers must not be part of the request, and are queued +independently. They are returned in decode order (i.e. the same order as coded +frames were submitted to the ``OUTPUT`` queue). + +Runtime decoding errors are signaled by the dequeued ``CAPTURE`` buffers +carrying the ``V4L2_BUF_FLAG_ERROR`` flag. If a decoded reference frame has an +error, then all following decoded frames that refer to it also have the +``V4L2_BUF_FLAG_ERROR`` flag set, although the decoder will still try to +produce (likely corrupted) frames. + +Buffer management while decoding +================================ +Contrary to stateful decoders, a stateless decoder does not perform any kind of +buffer management: it only guarantees that dequeued ``CAPTURE`` buffers can be +used by the client for as long as they are not queued again. "Used" here +encompasses using the buffer for compositing or display. + +A dequeued capture buffer can also be used as the reference frame of another +buffer. + +A frame is specified as reference by converting its timestamp into nanoseconds, +and storing it into the relevant member of a codec-dependent control structure. +The :c:func:`v4l2_timeval_to_ns` function must be used to perform that +conversion. The timestamp of a frame can be used to reference it as soon as all +its units of encoded data are successfully submitted to the ``OUTPUT`` queue. + +A decoded buffer containing a reference frame must not be reused as a decoding +target until all the frames referencing it have been decoded. The safest way to +achieve this is to refrain from queueing a reference buffer until all the +decoded frames referencing it have been dequeued. However, if the driver can +guarantee that buffers queued to the ``CAPTURE`` queue are processed in queued +order, then user-space can take advantage of this guarantee and queue a +reference buffer when the following conditions are met: + +1. All the requests for frames affected by the reference frame have been + queued, and + +2. A sufficient number of ``CAPTURE`` buffers to cover all the decoded + referencing frames have been queued. + +When queuing a decoding request, the driver will increase the reference count of +all the resources associated with reference frames. This means that the client +can e.g. close the DMABUF file descriptors of reference frame buffers if it +won't need them afterwards. + +Seeking +======= +In order to seek, the client just needs to submit requests using input buffers +corresponding to the new stream position. It must however be aware that +resolution may have changed and follow the dynamic resolution change sequence in +that case. Also depending on the codec used, picture parameters (e.g. SPS/PPS +for H.264) may have changed and the client is responsible for making sure that a +valid state is sent to the decoder. + +The client is then free to ignore any returned ``CAPTURE`` buffer that comes +from the pre-seek position. + +Pausing +======= + +In order to pause, the client can just cease queuing buffers onto the ``OUTPUT`` +queue. Without source bytestream data, there is no data to process and the codec +will remain idle. + +Dynamic resolution change +========================= + +If the client detects a resolution change in the stream, it will need to perform +the initialization sequence again with the new resolution: + +1. If the last submitted request resulted in a ``CAPTURE`` buffer being + held by the use of the ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag, then the + last frame is not available on the ``CAPTURE`` queue. In this case, a + ``V4L2_DEC_CMD_FLUSH`` command shall be sent. This will make the driver + dequeue the held ``CAPTURE`` buffer. + +2. Wait until all submitted requests have completed and dequeue the + corresponding output buffers. + +3. Call :c:func:`VIDIOC_STREAMOFF` on both the ``OUTPUT`` and ``CAPTURE`` + queues. + +4. Free all ``CAPTURE`` buffers by calling :c:func:`VIDIOC_REQBUFS` on the + ``CAPTURE`` queue with a buffer count of zero. + +5. Perform the initialization sequence again (minus the allocation of + ``OUTPUT`` buffers), with the new resolution set on the ``OUTPUT`` queue. + Note that due to resolution constraints, a different format may need to be + picked on the ``CAPTURE`` queue. + +Drain +===== + +If the last submitted request resulted in a ``CAPTURE`` buffer being +held by the use of the ``V4L2_BUF_FLAG_M2M_HOLD_CAPTURE_BUF`` flag, then the +last frame is not available on the ``CAPTURE`` queue. In this case, a +``V4L2_DEC_CMD_FLUSH`` command shall be sent. This will make the driver +dequeue the held ``CAPTURE`` buffer. + +After that, in order to drain the stream on a stateless decoder, the client +just needs to wait until all the submitted requests are completed. diff --git a/Documentation/media/uapi/v4l/ext-ctrls-codec.rst b/Documentation/media/uapi/v4l/ext-ctrls-codec.rst index bc5dd8e76567b688db0f1af37d050a229087b151..28313c0f4e7cc8f15fb344fdbe3e5146d6d8dac3 100644 --- a/Documentation/media/uapi/v4l/ext-ctrls-codec.rst +++ b/Documentation/media/uapi/v4l/ext-ctrls-codec.rst @@ -1713,10 +1713,14 @@ enum v4l2_mpeg_video_h264_hierarchical_coding_type - * - __u8 - ``scaling_list_4x4[6][16]`` - - + - Scaling matrix after applying the inverse scanning process. + Expected list order is Intra Y, Intra Cb, Intra Cr, Inter Y, + Inter Cb, Inter Cr. * - __u8 - ``scaling_list_8x8[6][64]`` - - + - Scaling matrix after applying the inverse scanning process. + Expected list order is Intra Y, Inter Y, Intra Cb, Inter Cb, + Intra Cr, Inter Cr. ``V4L2_CID_MPEG_VIDEO_H264_SLICE_PARAMS (struct)`` Specifies the slice parameters (as extracted from the bitstream) @@ -1796,7 +1800,7 @@ enum v4l2_mpeg_video_h264_hierarchical_coding_type - - * - __u32 - ``dec_ref_pic_marking_bit_size`` - - + - Size in bits of the dec_ref_pic_marking() syntax element. * - __u32 - ``pic_order_cnt_bit_size`` - @@ -1820,10 +1824,12 @@ enum v4l2_mpeg_video_h264_hierarchical_coding_type - - * - __u8 - ``num_ref_idx_l0_active_minus1`` - - + - If num_ref_idx_active_override_flag is not set, this field must be + set to the value of num_ref_idx_l0_default_active_minus1. * - __u8 - ``num_ref_idx_l1_active_minus1`` - - + - If num_ref_idx_active_override_flag is not set, this field must be + set to the value of num_ref_idx_l1_default_active_minus1. * - __u32 - ``slice_group_change_cycle`` - @@ -1983,9 +1989,9 @@ enum v4l2_mpeg_video_h264_hierarchical_coding_type - - ``reference_ts`` - Timestamp of the V4L2 capture buffer to use as reference, used with B-coded and P-coded frames.
