[FFmpeg-user] packet too large, ignoring buffer limits to mux it

[J. Bakshi ( জ. বকসী )]

Dear list,

I have two .vob files which are running fine.
I like to concat these two .vob with ffmpeg like

ffmpeg -f concat -i file.txt -c copy out.mpg

But during the operation ffmpeg reports

[mpeg @ 0x1ea2c20] buffer underflow i=1 bufi=22768 size=35155
[mpeg @ 0x1ea2c20] buffer underflow i=1 bufi=24800 size=35155

[mpeg @ 0x1ea2c20] packet too large, ignoring buffer limits to mux it

[huge repetition .................]

The resulting output file works well to some extend and at a specific point
it stuck with huge screaming noise.

Is there any option to fix this issue ?

Thanks
