mp4 file in MPEG-2 transport stream

[kazmihusnain]

Dear all,

I am new to video streaming. I want to encapsulate .mp4 file in mpeg-2 ts to calculate the overhead this encapsulation adds to the file. I don't want to re-encode the data. Please guide me how to do it. Any advice, tutorial or documentation is welcomed.

Regards,
Husnain

You can't do that...

You can encapsulate audio and video tracks from an MP4 file into an MPEG2-TS file, if the codecs are supported by MPEG2-TS. But you cannot encapsulate the MP4 per se. That does not even make sense.

Code: Select all

vlc myfile.mp4 --sout-all --sout '#standard{access=file,mux=ts,dst=myfile.ts}'

Thanks Remi and Jean,

I still am a little confused. Do you people mean to say that I need to first extract the audio and video streams from my mp4 file and then encapsulate them into MPEG-2 TS individually ???

and then what will this command do?

Code: Select all

vlc myfile.mp4 --sout-all --sout '#standard{access=file,mux=ts,dst=myfile.ts}'

isn't it taking an mp4 file and encapsulating it into MPEG-2 TS?

Thanks

No. It's decapsulating MP4 content and then encapsulating it into TS.

You cannot encapsulate a container into a container, at least not into TS.

Thanks I get it now,

But the problem is that when i use this command, nothing happens. I don't know why but when I replace the quotes with double quotes or just insert '=' sign, it does something, right or wrong I don't know. I am talking about the following commands:

Code: Select all

vlc rep128.mp4 --sout-all --sout "#standard{access=file,mux=ts,dst=myfile.ts}"

or

Code: Select all

vlc rep128.mp4 --sout-all --sout=#standard{access=file,mux=ts,dst=myfile.ts}

Please tell me if the output they are giving is the right output. Thanks.

Hi all,

I am able to encapsulate the streams into mpeg-2 ts. Can someone tell me whether the output stream is Constant Bit rate or Variable Bit Rate?


Thanks
