I could not find a > reference manual about that... The H.264 and MPEG-4 encoders support planar 4:2:0 subsampled formats only: YU12, YV12, and chroma-interleaved NV12. The JPEG encoder can also handle planar 4:2:2 subsampled frames, but none of the interleaved (YUYV, UYVY, ...) variants. > So back to the issue. > $> cat /sys/class/video4linux/video0/name > coda-encoder > $> v4l2-ctl -d0 --list-formats > ioctl: VIDIOC_ENUM_FMT > Index : 0 > Type : Video Capture > Pixel Format: 'H264' (compressed) > Name : H264 Encoded Stream > > Index : 1 > Type : Video Capture > Pixel Format: 'MPG4' (compressed) > Name : MPEG4 Encoded Stream > > $> v4l2-ctl -d0 --list-formats-out > ioctl: VIDIOC_ENUM_FMT > Index : 0 > Type : Video Output > Pixel Format: 'YU12' > Name : YUV 4:2:0 Planar, YCbCr > > Index : 1 > Type : Video Output > Pixel Format: 'YV12' > Name : YUV 4:2:0 Planar, YCrCb Please apply all coda patches in the media-tree master branch first.
