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.

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.

Do not set context colorimetry on the raw (OUTPUT) queue for encoders. Always set colorimetry on the coded queue (CAPTURE for encoders, OUTPUT for decoders). This also skips propagation of capture queue format and selection rectangle on S_FMT(OUTPUT) to the CAPTURE queue for encoders.
