Trouble playing MP4 file (MP41)

[ESPNSTI]

Hi there.

I have an MP4 file that refuses to be played by just about anything.
Quicktime says it's not a valid MPEG-4 file and it says that the 'moov' atom couldn't be found.
WMP Classic says it can't open it.
MPegable says it can't open it.
mp4UI says the atom size is invalid.

Now I do have another MP4 file that works just fine.
When I compared the first chunk of the file that doesn't work:

00 00 00 14 66 74 79 70  69 73 6F 6D 00 00 00 00
6D 70 34 31 09 62 F0 54  6D 64 61 74 C0 11 A4 CD
54 61 50 2A 20 B3 F8 00  00 03 F8 00 00 02 B1 00
00 00 00 12 81 12 85 41  4F 80 01 80 80 18 11 80

I noticed that the one that doesn't work is MP41 and the one that does work is MP42.

Is my file bad, or do most players and such not deal with MP41?
Ideas? Comments?

BTW, was this the right place to post this?

welcome to doom9

how did you create that file?

it seems your file (that doesnt work) doesnt have a moov atom, which basically is one of the most important ones
i would say your file simply isnt spec compliant to the mpeg-4 standard.

maybe you want to try your luck with renaming .mp4 to .mov or .3gp, but i am not sure it will help much

[Yong]

Try to decode it with ffdshow or mplayer

Unfortunately, I didn't create it.

[bond]

well the only thing i can say is that you could keep on trying either extracting the video/audio from the file with different mp4 tools

or playing it with more players

for a list of thos tools have a look at the mp4 faq

@ESPNSTI:
May be you can upload the file, and lets someone to hack it.

[multicone]

This is likely an AVI file with Microsoft MPEG 4 V1 codec, FourCC 'mp41', and not a MP4 file.

Here you go (it's a zip split into 9 parts, about 133MB).
Please only download it if you're going to try it, since I believe there is a download limit of 25 times on yousendit.

Also when I was googling for "ftypisom" I found several other MP4 files with headers that seemed similar to my non-working one, and sure enough I couldn't play those either (I don't have any idea what these movies are about):

http://hideout.musichall.cz/stuff/capture.mp4 (2MB)
http://hideout.musichall.cz/stuff/foo.mp4 (1.2MB)

Well I tried renaming to AVI, but that didn't work either.
If I read the header layout right ( http://www.geocities.com/xhelmboyx/q...mp4-layout.txt ), this appears to be an MP4 container.

[Yong]

I tried playing the foo/capture.mp4 with mplayer, with verbose switch,

here is the part of mplayer output:

h.264 video?
Any idea?

[bond]

i doubt its a raw h.264 stream as if so you wouldnt get a ftyp atom

still you might want to rename to .264 (try muxing this with mp4creator to .mp4)

0x56444152 is the id for libavcodec's implementation of rawDV audio (which I did not bother to compile into mplayer). Like the text in bold above and bond's comments: it does not seem to be a mp4 file at all.

Did anyone peek at the creation dates of these files ? http://hideout.musichall.cz/stuff/
scroll down to "capture.mp4 05-Mar-2002 23:51" - Who knows what specs were used to create these mp4's
Got my curiousity though

- this .mp4 file http://www.cs.ubc.ca/~westrom/animation.mp4
has the same ftypisom mp41 and plays fine plus I have Xvid files muxed with 3ivx into mp4 that show mp41 as well.

Some sort of early spec MP4 file?

I was able to play this one as well.

At the end of the "capture" file ( http://hideout.musichall.cz/stuff/capture.mp4 ), there was some text.
It doesn't mean much of anything to me, but perhaps it rings a bell for you :

MP4V-ES/90000

a=isma-compliance:1,1.0,1..a=mpeg4-iod: "data:application/mpeg4-iod;base64,AoCA

PS, thanks for all the help.

Tried,
mp4creator give me an abnormal program termination....

[bond]

some comments:

1) 2002 is not a that early creation date for a .mp4 file. the .mp4 specs are existing longer
2) these .mp4 files are not spec compliant no matter what you try (the moov atom is a very central part of .mp4, and its missing in these files) and therefore simply cant be handled by normal .mp4 tools, which are following the specs
3) therefore the only solution is to find out what tool created that file (someone wanting to send this "hideout.musichall.cz" guy a mail?) and use this for editing these files

Good idea.
I sent him an email.

[jumpjack]

sorry for digging up such an ancient thread, but I have same problem, and I cannot figure out which program was used to produce my MP4 file, as it is created by an EMTEC N100 digital recorder!

GSpot says:
isom: MP4 Base Media v1 [IS0 14496-12:2003]
- mp41: MP4 v1 [ISO 14496-1:ch13]

Hex editor says (header):
ftypisom mp41 mdat

I tested a dozen different players, none works.

Searching ISO 14496-1:ch13 I found this page :
http://www.ftyps.com/

But on http://www.iso.org/ site I couldn't find anyuthing useful.

Any help?
