Muxing to mp4 (x264 + Vorbis or LC-AAC)

[Meelis]

Hi

Muxing to mp4 (x264 + Vorbis or LC-AAC)
is it not possible, because MediaCoder can't do that?

Audio is encoded with MediaCoder
Video is encoded with MediaCoder or VirtualDub x264vfw or RipBot264.

Copy audio + copy video - mux to mp4 container.

32bit MediaCoder2011-R3-5135 and not only that version it goes months and months back.
Vista 64 bit. i have K lite mega codec pack 32 and 64 bit.

1280x720 30fps x264
Video file sources are
1) RipBot264v1.16.5 made mp4 or mkv container x264 encode
2) VirtualDub 1.9.11 32bit (x264vfw 114r1913bm 5fd3dce) avi x264 encode
3) mkvtoolnix-unicode-4.7.0 mkv container of some video encode from point 1) or 2)

Problem is it can't mux, it muxes to mp4 file only video part, even if i selected copy audio external file.
If i do encode in MediaCoder it does it and when it starts mux it files.

Why i need MediCoder is because RipBot doesn't have 500 kbits LC-AAC, but only 128kbits AAC for mp4.
I know mkv is much better but Vimeo and YouTube use mp4, i figured there must be some good in mp4.

In one case mediacoder demuxed from mkv merge mkv container video, an file that was 20 MB smaller than original mp4 file from ripbot (70 mb vs 87mb).
Ofcorse video was broken. But MKV merge had problems with that file in 1st place when muxing mp4 video and flac audio to mkv.

The mp4 from ripbot x264 encode displayed error in MKV merge gui:

and the 'CTTS' atom is needed for getting the timecodes right. As it is missing the timecodes for
this track might be wrong. You should watch the resulting file and make sure that it looks like you expected it to.

Can it be relevant that YouTube wasn't able to decode x264 video with some settings

YouTube decoded only some intra frames from such video:

Oo too bad mp4 container doesn't support vorbis audio.
And AAC is not mentioned atleast the LC-AAC

I figured mp4 is relatively new container but it's ages older than Ogg Vorbis and LC-AAC.

Perhaps i muxed AC3 audio and remembered wrong it beeing AAC.
Anyways LC-AAC 500 kbits is much better quality than AC3 576 kbits.

Thank good for mkv

Have you tried Handbrake?

No, but i can pretty much everything done with Virtualdub MediaCoder and mkvmerge GUI.

Afterall even YouTube can decode the file if i use:
* fast decode
* zero latency

I think this 2 options above will turn on this settings:
No cabac
no b-frames
weightp=0
rc=cqp
mbtree=0
