mux Apple compliant .mp4 / .m4v? mp4box doesn't do it for me
All of my encodes have the following elementary streams (video.264, audio.m4a (aac), audio.ac3, subtitles.srt, and chapters.txt). I mux them with mp4box using the following command
Code:
"c:\program files\gpac\mp4box.exe" -add video.264 -add audio.m4a:lang=en:group=1:disable -add audio.ac3:lang=en:group=1 -add subtitles.srt:lang=en:hdlr=sbtl:disable -chap chapters.txt -ipod -new "output.m4v" Since I use a Windows box to batch encoded movies, using Subler is out of the question. And although I'd love to use .MKV, I'd rather create .MP4/.M4V since most of my products are Apple (iPad, iPhone, Apple TV). What's everyone using to mux Apple compliant .m4v files? |

oops. Realized I started this thread in the wrong forum. Meant to be in the a/v container one.
But the good news is that MkvToMp4 also seems to fix the output of mp4box. Seems to have something to do with TKHD atoms. Quote:

You could give a try to L-Smash's muxer or remuxer...

In order to work out which streams are causing a problem I suggest you try generating 'test muxes' using just the video and audio streams first. And build up from there.
Apple media players can be extremely fussy with various stream combinations as their media players don't conform fully to the MPEG-4 ISO standard.

Life would be so much easier if Apple made their devices truly 'end-user friendly' and offered greater ISO 14496 compliance
