media: videodev2.h: RGB BT2020 and HSV are always full range

2020-11-05T10:51:18+00:00

[ Upstream commit b305dfe2e93434b12d438434461b709641f62af4 ] The default RGB quantization range for BT.2020 is full range (just as for all the other RGB pixel encodings), not limited range. Update the V4L2_MAP_QUANTIZATION_DEFAULT macro and documentation accordingly. Also mention that HSV is always full range and cannot be limited range. When RGB BT2020 was introduced in V4L2 it was not clear whether it should be limited or full range, but full range is the right (and consistent) choice.

media: media/v4l2: remove V4L2_FLAG_MEMORY_NON_CONSISTENT flag

2020-09-14T13:28:06+00:00

The patch partially reverts some of the UAPI bits of the buffer cache management hints. Namely, the queue consistency (memory coherency) user-space hint because, as it turned out, the kernel implementation of this feature was misusing DMA_ATTR_NON_CONSISTENT. The patch reverts both kernel and user space parts: removes the DMA consistency attr functions, rolls back changes to v4l2_requestbuffers, v4l2_create_buffers structures and corresponding UAPI functions (plus compat32 layer) and cleans up the documentation.

media: docs: dev-decoder: Add one more reason for dynamic change

2020-07-04T10:42:39+00:00

Add bit-depth change as one more reason which could change in the middle of the stream. For the worst case the stream is 8bit at the beginning but later in the bit-stream it changes to 10bit. That change should be propagated to the client so that it can take the appropriate action. In that case it has to stop the streaming on the capture queue, re-negotiate the pixel format, allocate new buffers and start the streaming again.
