Subject: [PATCH v2 00/11] Venus stateful Codec API
Hello,
Here is v2 of the Venus transition to stateful codec API
compliance. The v2 can be found at [1].
Changes since v1:
* codec_state is now enum
* dropped IS_OUT and IS_CAP macros and use vb2_start_streaming_called()
* corrected g_fmt and reconfig logic
* s/vdec_dst_buffers_done/vdec_cancel_dst_buffers
* use v4l2_m2m_ioctl_try_decoder_cmd M2M helper
* various fixes to make v4l2-compliance pass the streaming test
To test the streaming with --stream-from-hdr v4l2-compliance option I have
to make the following hack (it is needed because the size of decoder input
buffers (OUTPUT queue) is not enough for the h264 bitstream, i.e the driver
default resolution is 64x64 but the h264 stream is 320x240):
