Problems playing MP4s with Osmo4

[udi.wertheimer]

I am totally new to the MP4 container, and wanted to check out what it's capable of.
I downloaded http://www.comelec.enst.fr/osmo4/mp4/mediacontrol_animatrix.mp4 from this forums' MP4 FAQ and loaded it into GPAC Osmo4, and there is no picture or sound whatsoever (although the time indicator does progress), only giving me a black window and a "Stream Setup Failure: Media Codec Not Found" message in the status bar. From what I can understand from the FAQ, this player comes with all needed codecs, am I wrong? And besides, I have on my machine pretty much any MPEG-4 related codec I can think of...
The file wouldn't play on Quicktime 6.5 either.

I also tried http://isabelle.math.ist.utl.pt/~l52768/sw_sample.zip from a post about DVD menues ( http://forum.doom9.org/showthread.php?s=&threadid=66583 )... it did play, but with no menues, only the main film, without sound, and everything was kind of... green. I mean, had a strong green tint to it, don't really know how to explain it, I guess I could add a screenshot if you don't get what i'm trying to say...

So, am I doing anything wrong?

The MP4 test encode you downloaded does not actually contain an Mpeg4 compliant video stream. Even the audio is Mpeg2 (Mp3) and not AAC, which is more usually associated for use with the MP4 container!

That said the Osmo4 player should play it. Or you could try VideoLAN!

both samples, sw and animatrix, play here without any problems with the latest osmo4 player version from here (http://rarewares.hydrogenaudio.org/files/GPAC_0.1.2.exe) (no need to replace the dll anymore as stated in the sw sample readme as the aac decoding is already included in 0.1.2 by default)

videolan, quicktime doesnt handle the interactive part of these files (menus etc..)

I forgot that the animatrix encode had an interactive element!

However, if udi.wertheimer requires an example of an fully interactive encode with compliant streams, your StarWars encode is much better!

I don't have problems with playing mediacontrol_animatrix.mp4 and sw_sample.mp4 with Osmo4 too. And I didn't change any settings after installation to play it.
Osmo4 is very good. The only one that plays mp4 with menues correct.
But the things that are stoping me and maybe other people from using it is that it doesn't play Xvid and DivX with b-frames and it doesn't play 5.1 aac right.
I hope it will be fixed some day.

there are now 2 mpeg-4 decoder plugins: one based on xvid and the other based on ffmpeg

I just tested Osmo4 0.1.2 with Xvid 1.0 RC2.
1 b-frame, Closed GOV enabled.
Packed Bitstream, qpel and gmc are disabled.
MP4 made with 3ivX muxer and GraphEdit.
Osmo4 doesn't play it with any decoder plugin.
The same without b-frame is playable.
Strange thing is that AVIs with b-frame are playable. But MP4s are not.
And OpenXviD Decoder didn't play anything at all.
Decoding Error: MPEG-4 BitStream Not Compliant.

Well I tried the two files again on another machine, and got the exact same results. I have no idea what's wrong, I guess I'll try to make my own MP4 and see what happens.
