[FFmpeg-user] mpg to mp4 request

[wally]

Hello Carl Eugen,

thank you for reply!

I tried the obvious commandline with a fragment of my sourcefile and the
result was acceptable. sizereduction and quality was OK and i can play on
the SAT Receiver.

After this test i tried with the entire sourcefile (3.4 GB). It results 
in a 1.3GB mp4 file
which doesn't work on the receiver. Message: "Video resolution not 
supported"

But the mp4 of the fragment works.
ffmpeg -i fragment.mp4
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 
720x576 [SAR 64:45 DAR 16:9], 1890 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 
tbc (default)

ffmpeg -i full.mp4
Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 
720x576 [SAR 64:45 DAR 16:9], 1890 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 
tbc (default)

For me all this is not obvious :)
