Problem converting from MPEG Program Stream to Transport Stream

[vivajam]

Hi,

I'm trying to convert MPEG files from Program Stream into Transport Stream without re-encoding the video. I found some free tools which work as txmuxer. The problem is that some of the files are impossible to convert, it says that program stream map is too large. It should be 18 bytes while my files have 24 bytes.

How can I fix this? Is there any program that can convert the large PS map size files?

Thanks!

does it help if you try demuxing it to elementary assets first?


another option you can try is ffmpeg

ffmpeg -i input.mpg -vcodec copy -acodec copy -f mpegts output.m2ts

Oh, I had forgotten ffmpeg, thanks!

I've tried with TsRemux and it seems it works. But I'd like to use ffmpeg if possible cause it makes my workflow more efficient. I could program a GUI to use it only for this conversion. When I try to make the conversion with ffmpeg there's an error. It says:

st:0 error, non monotone timestamps 57057 >= 57057
av_interleaved_write_frame(): operation not permitted

The number changes with each file. Why does this happen? I've tried to read ffmpeg documentation but I come to nothing. Is there any other options I should use??

thanks again

P.s. I forgot to mention that these files are MPEG PS encapsulated but its video codec is H.264.

not sure what the error indicates, it could be errors in the program stream

try adding
-vbsf h264_mp4toannexb

[vivajam]

-vbsf adds more errors. Thanks anyway!

I've looking the monotone stamps error on the net and it seems that is an old well-known bug in ffmpeg, apparently it's still there and have not been solved.

Meanwhile I have to use TsRemux and wait for this bug to be solved.

Thanks!!

You could use MPEGStreamclip or ProjectX or have you already tried these?
