x264 produces crap output, players crash

Egladil · 4th February 2006, 01:00

I have a problem: I've encoded some movie and the resulting mp4 file is 6GB, the problem is that if I seek to the data which is beyond the 4GB border, every player crashes, mp4box crashes. I'm able to mux the video in mkv, beu there every player crashes too and when trying to demux the raw stream only 4 GB are written and then mp4box (or mkvextract) crashes.

Anyone knows what I can do?

So... your encode is bigger than the source?

Egladil · 4th February 2006, 01:02

no, the source is 14 GB, it's HD material.

Manao · 4th February 2006, 12:19

What was the version of x264 you used ? And mp4box ? And mkvtools ?

I Have the exact same problem as you... i encode at 6mbits and around 1h33:54sec (witch is 4gig approx) it crash for a my encode. All movies under that mark work like a charm!

Rev408, and the MP4 itself crash so it's a problem with the encoder, VLC crash, FFDSHOW crash, CoreAVC Crash all without audio

I used x264 rev410 cli, mp4box 0.4.1-dev. I must be a bug in x264 or gpac, I'll try encoding to raw stream, but it'll take a few days.

You can use very fast settings, it shouldn't matter. That may speed things up.

Egladil · 5th February 2006, 02:19

Ok, did some tests, it seems that mp4 output is b0rked. encoding to raw stream, playback with vlc-> ok, muxing with latest mp4box and then playing->crash. encoding to mkv->works.

as stated before the players crash on the 4 GB border

run mp4dump from mpeg4ip on the output mp4 and post the log here plz

Egladil · 5th February 2006, 17:29

On a 9GB mp4 mp4dump says:

mp4dump version 1.2.8
ReadChildAtoms: of root
ReadAtom: pos = 0x0
ReadAtom: type = "ftyp" data-size = 16 (0x10) hdr 8
Read: majorBrand = avc1
Read: minorVersion = 0 (0x00000000)
Read: compatibleBrandsCount = 2 (0x00000002)
Read: brand = isom
brand[1] = avc1
ReadAtom: pos = 0x18
ReadAtom: type = "mdat" data-size = 9074710898 (0x21ce51972) hdr 16
Skip: 9074710898 bytes
ReadAtom: pos = 0x1ce5199a
ReadAtom: type = "free" data-size = 33 (0x21) hdr 8
Skip: 33 bytes
ReadAtom: pos = 0x1ce519c3
ReadAtom: type = "p,3" data-size = 1108602032 (0x4213ecb0) hdr 8
Warning: atom type p,3 is suspect
Warning: p,3 atom size 1108602032 is suspect
Read: data = <1108602032 bytes>
...
then comes 3.5 Gb of data
...
ReadAtom: pos = 0x5ef9067b
ReadAtom: type = "¯¾^" data-size = 1659965119 (0x62f10ebf) hdr 8
Warning: atom type ¯¾^ is suspect

then it bails out while printing "MP4ERROR:" on the console (stdout was redirected to a file)

bond · 5th February 2006, 17:51

what verbose level did you use? try without setting verbose, the file should be much smaller

Egladil · 5th February 2006, 17:53

I used verbose=3

without verbose it just works for a while, then prints "MP4ERROR:" and exits

bond · 5th February 2006, 18:09

does the verbose output mention "stco" or "co64" somewhere?

Egladil · 5th February 2006, 18:16

no it doesn't

bond · 5th February 2006, 18:42

can you upload the output of mp4dump when not using verbose somewhere?

Egladil · 5th February 2006, 18:46

it has no output other than "MP4ERROR:"

KWAGGA · 6th February 2006, 02:16

I prefer mkv container, less hassle then mp4 and supports more streams, mp4 is pretty cool though especially using mp4 box to extract streams.

try muxing the raw stream with mp4creator to mp4 and check if that file works better

Egladil · 6th February 2006, 17:04

well the version 1.2.8 of mp4creator (i didn't find binaries of later versions) produces pretty crap mp4 output, the seeking is corrupt after 2GB and the player crashes after 4 GB
