* avcodec/v4l2_m2m: fix av_pix_fmt changing when multiple /dev/video* devices ↵Aman Gupta2019-09-101-1/+2
| | | | | | | | | | | | are probed On the RPI, three different /dev/video devices exist (decoder, scaler, encoder). When probing the devices in order, the originally requested pix fmt would be mutated causing the wrong one to be chosen when a matching device was finally found.

This patchset enhances Alexis Ballier's original patch and validates it using Qualcomm's Venus hardware (driver recently landed upstream [1]). This has been tested on Qualcomm's DragonBoard 410c and 820c Configure/make scripts have been validated on Ubuntu 10.04 and 16.04. Tested decoders: - h264 - h263 - mpeg4 - vp8 - vp9 - hevc Tested encoders: - h264 - h263 - mpeg4 Tested transcoding (concurrent encoding/decoding) Some of the changes introduced: - v4l2: code cleanup and abstractions added - v4l2: follow the new encode/decode api. - v4l2: fix display size for NV12 output pool. - v4l2: handle EOS (EPIPE and draining) - v4l2: vp8 and mpeg4 decoding and encoding. - v4l2: hevc and vp9 support. - v4l2: generate EOF on dequeue errors. - v4l2: h264_mp4toannexb filtering. - v4l2: fixed make install and fate issues. - v4l2: codecs enabled/disabled depending on pixfmt defined - v4l2: pass timebase/framerate to the context - v4l2: runtime decoder reconfiguration. - v4l2: add more frame information - v4l2: free hardware resources on last reference being released - v4l2: encoding: disable b-frames for upstreaming (patch required) [1] https://lwn.net/Articles/697956/ System Level view: v42l_m2m_enc/dec --> v4l2_m2m --> v4l2_context --> v4l2_buffers Reviewed-by: Jorge Ramirez <jorge.ramirez-ortiz@linaro.org> Reviewed-by: Alexis Ballier <aballier@gentoo.org> Tested-by: Jorge Ramirez <jorge.ramirez-ortiz@linaro.org> Signed-off-by: wm4 <nfxjfg@googlemail.com>
