I am running Android 9 on an Odroid N2+ with a UGA-3000 adapter over a DVI cable (I have also tried with a HDMI cable) and when I try to play a H264 (mp4) video, I only get audio, no video. I have tried with multiple applications (VLC, Movie Player) and get the same results.
I have narrowed it down to an encoding (CODEC) issue, some encodings work and some don’t, I am including (since I don’t see a way to attach a file) two files; works.txt and fails.txt, which are the ffprobe information for two mp4 videos, one that works and one that ‘fails’. I am not a video expert so perhaps someone could aid me in seeing the problem.
