Hi all,
I'm having a small issue encoding video with the Raspberry Pi's
hardware encoder, available as a V4L2M2M device that ffmpeg can use in
current firmware/kernel versions.
If I try to encode a video where the width is not a multiple of 64

List folk,
I've been working around a strange encoder and stream source problem;

If I understand correctly, your command line uses the Libavfilter input virtual
device and a multimedia source.
If the success of that command line depends on either, please clarify how in
