I use OBS for record video (audio setting is mp3)
but when i use mkvtoolnix to merge or split it
the audio will lost
but when i use aac for audio setting than can work well
does mkvtoolnix not support video's mp3 audio?
mkvmerge supports MP3 just fine. It's likely something about your source file that mkvmerge doesn't handle yet. If you want me to look into it, then I need access to such a source file. Please upload it somewhere, e.g. to my FTP server.
when we play this file it have audio
when we merge/split than not
Thanks. I'll look into it.
MP4: determine track parameters from bitstream for MP2 audio, too
In this case the track contains MP3 data. However, the ESDS's object
type ID field is set to 0x6b in the headers indicating MP2. Additionally
the track's fields for channels & sampling frequency are set to 0.
New pre-builds for Windows including the fix are available.
