How to Join / Muxing / Merging Webm Video + Audio Files?

[devilcoelhodog]

Hello, dear all.


1) Does it possible to join / muxing Webm video files + audio files?


2) If it is possible, which programs do I need for this task?


3) The audio files must be in some specifical formats to be muxed into webm? Any convertion into specifical audio format / specification is needed?


4) If ffmpeg is the program that can help in this task, how to use it? Only command line use? Any GUI for this specifical task: muxing / joining video + audio files ?


Thanks for the tips!

Best regards.

WebM has specific requirements. It may contain VP8 / VP9 video (developed by Google) and Ogg Vorbis / Opus audio, multiplexed into an MKV container with some restraints. I would recommend trying the converter "Hybrid" (made by Selur). More suggestions on the WebM Project tools page...

Hello!

Thanks for the tips!


My goal is just testing for curiosity: if I go to youtube and would wanna get some videos from there ( or similar places).

If I use such add on ( for Firefox) to get the videos ( or similar sites ), just using program like from this link:

And get some separated "streams" and wanna mux / merge audio + videos in Webm format, how to proceed!

Best regards!

Probably using the mkvtoolnix package (mkvmerge for CLI or mmg as GUI), adding the streams and enabling WebM restrictions (mmg: in the "Global" tab) before saving the MKV as *.webm file.
