muxing h.264 in mp4

[ivan_alias]

Does anyone know of a way to put h.264 in an mp4 container? (in windows)

I thought mp4creator would work, but the version I have is from May and it doesnt seem to like the raw h.264 bit stream.

Videolan doesnt seem to do it.

mencoder doesnt output mp4

ffmpeg doesn encode h.264

Im stuck!

Anyone have an idea of how to do this!?

Thanks a lot

I made some x264 encodes with ffdshow in AVI container. I was able to mux them to MP4 with VLC latest 0.8.0 beta. Nero Showtime was able to decode that files, so give it a try.

edit: typo

[bond]

latest cvs of mp4creator should do it too

[pogo stick]

Is there anywhere I can find compiled version of it?
And by the way, does VLC produce compliant mp4 files now?

[tiki4]

Here, latest beta package (0.8.0-test2), dunno about mp4creator, I could possibly compile it for Linux, though.

NO, VLC doesn't produce compliant mp4 files.

"mp4.c" have not changed for 2 months.( http://developers.videolan.org/cgi-b...k/modules/mux/ )

Fenrir has made a tool to store raw video h.264 in an AVI container. I haven't tested yet but you can grap it here. Then, with mp4crator you could create your mp4 file.

no need for that, since mencoder can output avi already. Also, mp4creator does not like to use avi files, and v1.1 does not recognize h.264 streams in the avi container.

I'll give another shot at compiling the mpeg4ip CVS at home and try to mux it. If it works I'll upload the binaries somewhere.

Thanks gotaserena

Hope it works!

then I hope videolan will be able to play it back..

[gotaserena]

CVS worked fine in linux:

$ mp4info video.mp4
mp4info version 1.1.7
video.mp4:
Track Type Info
1 video H.264, 203.520 secs, 1068 kbps, 320x256 @ 25.000000 fps
Metadata Tool: mp4creator 1.1.7

I even muxed two video streams in the same file by mistake! :P

In case pp are trying to play it in mplayer (best for slow < 2.0GHz computers), just remember to edit codecs.conf:

videocodec ffh264
info "FFmpeg H.264"
status working
fourcc H264,h264,avc1
format 0x10000005
driver ffmpeg
dll h264
out YV12,I420,IYUV

since mp4creator changes the fourcc of the stream when importing. I don't know if celtic_druid's builds have this problem, but it did show in my compilation.

[ivan_alias]

Well this is good news.

Does anyone have a windows compile?? :-)

[gotaserena]

here!

Seems to work here (in a P4), but don't blame me if it breaks anything (or itself).

hm, i read somewhere that the nero filters can play h.264 vlc-muxed .mp4 files, so i dunno if they arent spec compliant already and the failure was in neros filters

or do you have other info, why these files are not compliant?

[Drachir]

I posted here a question to mp4 files produced with vlc: http://sourceforge.net/forum/forum.p...orum_id=287546

Jean Le Feuvre1- the IODS box/atom is optional in MP4 specification
2- more quoting:
"There are a number of possible file types based on usage, depending on the descriptor:
· Presentation, contains IOD which contains a BIFS stream (MP4 file)
· Sub-part of a presentation, contains an IOD without a BIFS stream (MP4 file)
· Sub-part of a presentation, contains an OD (MP4 file)
· Free-form file, referenced by MP4 data references (free-format)
· Sub-part of a presentation, referenced by an ES URL.
NOTE - The first three are MP4 files, a file referenced by a data reference is not necessarily an MP4 file, as it is free-format. Files referenced by ES URLs, by data references, or intended as input to an editing process, need not have an Object Descriptor Box."


so the files created by VLC should not be treated as "compliant MPEG-4 presentation" by a player - which doesn't mean it won't read it, cf gpac

ah thanks, totally forgot that thread

[gotaserena]

ffdshow-20041012 doesn't like avc1 in mp4 it seems. I just manage to open a h.264 encode done by mencoder in avi using graphedit, but if I mux the raw stream into mp4 using mp4creator I can't decode it anymore. Splitter was 3ivx's. I changed the fourcc from h264 to avc1 and ffdshow still played it.

VLC 0.8-2 opens the mp4 without any problems, though.

[bond]

the 3ivx splitter doesnt support avc-in-mp4, you cant use it with such files!

[gotaserena]

Yes, now I see that. But isn't the splitter supposed to give some error message when it encounters a track that it cannot handle?

[gotaserena]

Ok, I've managed to encode my first H.264+5.1AAC using mencoder, faac and mp4creator! I'm feeling like that ape from 2001: clutching at bones trying to figure them out!

Bad news is that mp4creator still has some trouble importing AVC. Even with --rate=25 the reported fps of the video stream is "61.553780 fps". mplayer (linux) did not complain, though. VLC plays it also but reports the length of the video as 11h35min, and only decodes stereo. I have to wait till next moonlights beta splitter to try ffdshow.

[ak]

Hm, just checked bunch of samples lying around (.mp4's with x264 encodes inside), it shows fps correctly on all of them (mp4info that is). They are mostly video-only though.

As for decoders, moonlight h264 ds decoder is the only one that can decode b-frames correctly at the mo. Even with new nero filters it's jerky and corrupted all over the place, just like with lavc :shocked:
