* request: Check required v4l2 capabilities after opening the video nodePaul Kocialkowski2018-08-061-5/+13
| | | | | | | | Since our use of the v4l2 API has some assumptions on the available userspace APIs, check the capabilities reported by the driver to make sure they are supported. Signed-off-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com>
* v4l2: Add support for querying capabilitiesPaul Kocialkowski2018-08-062-0/+22
| | | | | | | | This adds a helper function to query v4l2 capabilities, returning either the device caps when available or the general device caps otherwise. Signed-off-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com>

| | | | | | | | This adds support for MPEG2 quantization matrices, which are optional given that fallback default matrices are used (on the kernel side) when no such matrix is provided. Signed-off-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com>

* Grab the base index when allocating buffers and mapping themPaul Kocialkowski2018-07-204-9/+20
| | | | | | | | | | | | | | Because there might be more than a single call to CreateSurfaces, we cannot assume that the index relative to the number of surfaces requested in a single call matches the v4l2 index. Grab the base index (as returned by the kernel) when allocating buffers and use it for memory mapping and addressing them in v4l2. This avoids memory-mapping the first (index 0) buffer multiple times in that scenario instead of the n-th allocated buffer (in the n-th call in the sequence).

* context: Liberate output and capture buffers at ContextDestroyPaul Kocialkowski2018-07-201-3/+23
| | | | | | | | | | | | | The V4L2 API does not currently provide a way to liberate allocated buffers one by one (which would fit well with DestroySurfaces in VAAPI). Moreover, streaming needs to be off before liberating buffers is allowed. As a result, output an capture buffers can only be liberated when destroying the decoding context, all at once, such as implemented in this patch.

* v4l2: Introduce helper to request buffersPaul Kocialkowski2018-07-202-0/+22
| | | | | | | | | | Although this is not needed when using the combination of CREATE_BUFS and QUERYBUF V4L2 ioctls (as currently done) to allocate and prepare buffers, the REQBUF ioctl is useful to liberate the buffers after use. This introduces a helper for this purpose. Signed-off-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com>
* Rename request_buffer helper to query_bufferPaul Kocialkowski2018-07-204-14/+14
| | | | | | | Since the V4L2 ioctl is called QUERYBUF, it makes more sense to call the associated function with the same name. Signed-off-by: Paul Kocialkowski <paul.kocialkowski@bootlin.com>

* h264: Fix prediction weight tableMaxime Ripard2018-07-171-21/+38
| | | | | | | | | | | | | | | The current code sets the prediction weight table by doing a memcpy of the libva structure to the v4l2's structure. However, for the offset and weight parameters, libva's structure uses 16-bits integer, while v4l2 uses 8-bits, which obviously doesn't work well with memcpy. Create a function to copy those arrays and matrices instead that follows the algorithm defined in the H264 spec, and use it so that it works properly. Signed-off-by: Maxime Ripard <maxime.ripard@bootlin.com>
* h264: Implement local cache of the latest decoded picturesMaxime Ripard2018-07-174-36/+220
| | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | | The libva only provides the reference images needed to decode the current picture, but not the full DPB. However, some codecs need that whole DPB in order to decode a picture. For example, the Allwinner hardware codec has an internal SRAM, with each picture getting a slot in that SRAM, and during each decoding process, some metadata will then be generated from that SRAM content to a separate buffer. Therefore, each frames must be located at the same SRAM position each time so that the metadata are then re-used properly. However, since libva will only pass a few reference images, we can end up in a situation where multiple, subsequent, frames will have the same reference images set, but might all be used as reference later on and cannot therefore be located at the same position. And from a more theorical point of view, Linux expects a full blown DPB in its H264 control. In order to work around this, we can create a shadow of the DPB by simply maintaining a list of 16 decoded images, each associated with their VAPictureH264 and an age. This age is the last time we used that frame as reference. When a new picture is decoded, either we assign it to a free slot, or we reuse the slot from the frame that hasn't been used as a reference for the longest time. This is a much simpler approach than the one documented in the H264 spec, but this shouldn't really be a problem since we don't handle the reference frames ourselves, but just re-use the one from the libva, and taken from the bitstream before. As such, frames that are not supposed to be used for reference will not be anymore, their age will not increase, and therefore after a while we will garbage-collect their slot to store a much newer frame.

* h264: Pass the context to the sub-control functionsMaxime Ripard2018-07-171-4/+9

| | | | | | | | | The coding style has been a bit erratic. Enforce the linux kernel coding style by reusing their .clang-format file, running clang-format on the source, and ignoring the few shortcomings that clang-format has at the moment (especially on aligning the define values).
