Extracting/demuxing a .TS into separate video and audio files?

[mkvbob]

I've got a .ts file on which I think there is about 32gb of mpeg2 video and 5gb DTS audio.

Can anyone suggest a good way to extract the contents into standard mpeg2/DTS files?

projectx

ok thanks, it all worked great until the audio, where it gave me this error:

--> AC-3/DTS Audio on PID 0x14
-> check CRC of AC-3 / MPEG-Audio L1,2
-> delete CRC in MPEG-Audio Layer1,2
-> add frames
!>  15 PTSs discarded in stream
stopped...

-> we have 10 warnings/errors.

what should I do about this?

Does not mean that audio is unusable. If you have a non-linear video editor, open both files in and you will find that the timeline is exactly the same.

ProjectX strips out useless information and replaces bad packets, ie. its fixing the stream for you, so that it is useful and playable.

[mkvbob]

Uh, ok, but the thing is that it only created me a .m2v video file and then stopped because of this error before making any audio file available. Which "both files" do you mean?

Give TsMuxeR a try

[DVWannaB]

Ok, since it only created a video file then there were errors detected in your audio that it could not fix. Try a free software called MPEG2Repair. This app creates a whole new *.ts file and can fix errors in the stream. If that goes without a hitch, then open it in ProjectX and demux the newly created file.

[mkvbob]

I did use MPEG2Repair prior to demuxing it with projectx, and as far as i understood everything was fine with the .ts, even though it did make me an identical copy of it.

Maybe this error has got to do with projectx running out of memory or something?

Give TsMuxeR a try

Alright thanks, I'll give it a shot if I won't manage to fix this error in projectx

[mkvbob]

Actually, I can see now that it did create an .ac audio file, even though the log said that the process was stopped.

Anyway, these are the files I've got together with the ones made by TsMuxeR, is there any reason for me to prefer either one of these over the other?

ProjectX: 32gb .m2v / 5gb .ac
TsMuxeR: 32gb .mpv / 5gb .dts

[DVWannaB]

no, not really. Keep them both just in case you run into a stubborn file that one might handle better than the other.

Yes, ProjectX does have the "file stopped" text. Its kind of an awkward way of saying it has completed the action
