ffmpeg vs mp4box

[leandro]

Hey everyone!

I made a script to proccess a bunch of AVI files:
- extract audio
- fix mp3 header
- normalize volume aac/mp3
- pack fixed audio + untouched video into a mp4 container.

My question is whether to use ffmpeg or mp4box to join the streams. Both produce the final .mp4 file.

Which one would be the more suitable to maximize performance and compatibility (if there any difference)

I have used MP4 (AVC/AAC) files created with FFmpeg on a variety of hardware devices, from bluray players, to media players (like WDTV), to games consoles like PS3 and Xbox 360.

Never had a problem.

Well, I'll stick with ffmpeg then.
Cheers!

better use mp4box, ffmpeg tends to produce non-compliant stream from time to time (through mplayer and ffplay normally play them without problems)

@ Selur:

speaking of MP4Box, I think it would be good to pester jeanlf again

See below the MedInfo capture TITLE
mp4box always generate that trash for the title if i do not specify one.
How do I disable that?

That's a bug in MediaInfo, not mp4box.

it might work to add an empty track name as workaround:

name=Val specifies the name to give to the media track.

-> just tested,... it does help, seems like MediaInfo assumes that there has to be a Title entry,.. and takes whatever it suspects to be one,..
