2018-12-07media: coda: fix H.264 deblocking filter controlsPhilipp Zabel
Add support for the third loop filter mode V4L2_MPEG_VIDEO_H264_LOOP_FILTER_MODE_DISABLED_AT_SLICE_BOUNDARY, and fix V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_ALPHA and V4L2_CID_MPEG_VIDEO_H264_LOOP_FILTER_BETA controls. The filter offset controls are signed values in the -6 to 6 range and are stored into the slice header fields slice_alpha_c0_offset_div2 and slice_beta_offset_div2. The actual filter offsets FilterOffsetA/B are double their value, in range of -12 to 12. Rename variables to more closely match the nomenclature in the H.264 specification.

Consistently add the context index to debug output, which otherwise is impossible to make sense of when two contexts are running concurrently. For this purpose, add a convenience macro coda_dbg(). Use the function name with the coda_ prefix stripped as keyword where applicable, and consistently use vid-out and vid-cap names for the queues. Add sequence counters to the decoder job finished message and correctly indicate B frames. Add a start streaming message to complement the stop streaming message and a start encoding message to complement the existing start decoding message.

2018-11-23media: coda: limit queueing into internal bitstream bufferLucas Stach
The ringbuffer used to hold the bitstream is very conservatively sized, as keyframes can get very large and still need to fit into this buffer. This means that the buffer is way oversized for the average stream to the extend that it will hold a few hundred frames when the video data is compressing well. The current strategy of queueing as much bitstream data as possible leads to large delays when draining the decoder. In order to keep the drain latency to a reasonable bound, try to only queue a full reorder window of buffers. We can't always hit this low target for very well compressible video data, as we might end up with less than the minimum amount of data that needs to be available to the bitstream prefetcher, so we must take this into account and allow more buffers to be queued in this case.

2018-11-23media: coda: always hold back decoder jobs until we have enough bitstream ↵Philipp Zabel
payload The bitstream prefetch unit reads data in 256 byte blocks with some kind of queueing. For the decoder to see data up to a desired position in the next run, the bitstream has to be filled for 2 256 byte blocks past that position aligned up to the next 256 byte boundary. This should make sure we never run into a buffer underrun condition if userspace does not supply new input buffers fast enough.

2018-09-24media: coda: don't overwrite h.264 profile_idc on decoder instanceLucas Stach
On a decoder instance, after the profile has been parsed from the stream __v4l2_ctrl_s_ctrl() is called to notify userspace about changes in the read-only profile control. This ends up calling back into the CODA driver where a missing check on the s_ctrl caused the profile information that has just been parsed from the stream to be overwritten with the default baseline profile. Later on the driver fails to enable frame reordering, based on the wrong profile information.
