remuxing mp4 to mpeg ts

Postby khilliard » 20 May 2007 06:34

I have movies (h.264/mp3) stored in .mp4 format. I used the VLC wizard to convert to mpeg ts. When done the result contains only audio. The .mp4 movies play fine with VLC. The steps I followed are:

1.) select Transcode/Save to file
2.) Select the .mp4 file to remux via 'Select a stream' file chooser
3.) On the 'Transcode' page I leave unchecked both 'Transcode video' and 'Transcode audio'
4. On the 'Encapsulation form' page I select MPEG TS radio button
5.) I select the filename for the mpeg ts file and click 'Finish'

I running the current 0.8.6a version under Windows XP. Any ideas???

Try transcoding to MP2v and use fps=<framerate> (use the source frame rate) on the command line as the last video option and the audio to a52.

I'm not familiar with the VLC command line but will read up. Not familiar with MP2v but I assume by the name that it is an mpeg2 container. Does this container support mp3 instead of a52? I assume that the operation is just remuxing and not real transcoding (it takes 8-10 hours to transcode to h.264, whew!).

My real problem is that I need a mpeg ts container as I will be streaming the content to a (amino) STB and this is the only format that it will accept. Is there a way to convert from mpv2 to mpeg ts?

I assume since you suggested mp2v that there are known problems with going from mp4 to mpeg ts either thru the wizard or command line. I tried using another remuxing program (Elecard) but the playback had terrible sync, only working with their own player. I would try almost anything that will allow me to playback h.264 video in mpeg ts format. Any suggestions???

I am a relative newbie to video containers/formating/streaming so I hope all this doesn't sound silly. Much appreciation for your suggestions and help.

h.264 in a MPEG TS container has very little support for a computer. AAC (MP4a) literally has no support in a MPEG TS container so a52 (ac3) is a viable solution. VLC is supporting this, but the support is ongoing.
