I have an MP4 that plays just fine using omxplayer omxplayer F.mp4
If I use the -i flag, I get the following media information
Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'F.mp4':

I'm experimenting with simple streaming into omxplayer, without success. e.g.
cat F.mp4 | omxplayer -o hdmi --no-keys pipe:0
omxplayer prints
Video codec omx-h264 width 640 height 480 profile -99 fps 30.000000 Audio codec aac channels 2 samplerate 44100 bitspersample 16 Subtitle count: 0, state: off, index: 1, delay: 0
It seems to have figured out the write demux and codec to use. But then nothing. No vid or sound. Just sits there without even the courtesy of an error message.
If I add -b then the screen blanks, so omxplayer is definitely able to send that change to the hdmi output
This may seem a bit pointless,but I am trying to understand the streaming mechanism with a view to replacing the cat with nc, or some other mechanism to provide streaming. I want hw accelerated video rendering so I figured omxplayer was the way to go.
Tried --genlog and it generated an omplayer.log as shown below, but I can't interpret it. Any ideas?
