2018-12-03media: venus: fix reported size of 0-length buffersAlexandre Courbot1-3/+1
The last buffer is often signaled by an empty buffer with the V4L2_BUF_FLAG_LAST flag set. Such buffers were returned with the bytesused field set to the full size of the OPB, which leads user-space to believe that the buffer actually contains useful data. Fix this by passing the number of bytes reported used by the firmware.

2018-11-23media: coda: limit queueing into internal bitstream bufferLucas Stach1-0/+28
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 Zabel2-5/+20
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.
