Hi,

tried this:

What in a hell this thing "non monotonically increasing dts" ?
Maybe is better to disable this, so it will don't cause any problem ?

[Carl Eugen Hoyos]

Are you suggesting that FFmpeg should produce invalid files by default?

[StevenG]

Replying to cehoyos:

Are you suggesting that FFmpeg should produce invalid files by default?

No, for sure.

I found a solution how to work around this bug:

1. i extract *.h264 with mkvextract
2. ffmpeg -i VIDEO.h264 -i AUDIO -c copy VIDEO.mp4
3. i got messages

   pts has no value
   [mp4 @ 02235020] pts has no value
       Last message repeated 53 times
   

but i got partially working *.mp4 media [on xbox 360 NOT a smooth playback].

Hope this helps.

With latest ffmpeg this now fails with:
pts (0) < dts (40) in stream 0
av_interleaved_write_frame(): Invalid argument
instead of non monotonically increasing dts

[Carl Eugen Hoyos]

This is not reproducible anymore.
