MP4 creation fail

[kotrtim]

I read Doom9's "Creating MP4 files - ISO compliant MPEG-4 streams with AAC audio"
guide

Step 1: Encode video

Please follow one of the abovementioned guides to encode your video. As a better alternative, you can use my very own MeGUI for encoding. You can set it to produce a raw file, which is best for what we're going to do.

This is bad... The first time I tried to encode x264, (RV 391A), I followed
the mentioned method, creating a RAW stream with MeGUI-x264 (HQ-Slow) first, the encoding is ~3.8 fps and it took me ~12 hours to encode. When I tried to mux the RAW stream with AAC into MP4 with MeGUI 0.2.3.1b (MP4Box - GPAC version 0.4.1-DEV)
....the video importing halt at 84%. I tried YAMB 1.4 and have no luck
Finally, I tried to use avc2avi and it works. But too bad, its avi, I deleted
the file and encode again!

This time, I use x264 RV 392A, encode to MP4 instead of raw,
and the resulting can be also muxed with AAC with MeGUI without
any problems.

For safety reasons, I think it's safer to encode to MP4 instead of RAW since mp4box also support mp4 importing

can you try again with the latest mp4box from here (http://www.aziendeassociate.it/cd.asp?dir=/gpac/dev)

also whats your video framerate? does it also stop importing if you set -fps 25?

[kotrtim]

I set the frame rate to 23.976 in MeGUI

anyway, when I import with yamb 1.4, I didn't set frame rate, the default is 25fps? And yet it failed

MeGUI/YAMB 1.4 also cannot import .sub file created with Vobsub ripper
... Only .srt works! I thought .sub is supported?

And the link you gave me, the mp4box version is the same as the one i'm using.

... Only .srt works! I thought .sub is supported?Well.. the text based .sub is supported... but not VobSub (which is probably what you're looking for).. there's somebody who managed to write a vobsub mp4 muxing tool and promised a patch for mp4box.. but so far it hasn't surfaced yet

kotrtim , make a bug report about this on the mp4box bug tracker (http://sourceforge.net/tracker/?atid=571738&group_id=84101&func=browse) plz

I don't really know what to tell the devs.... can you help me please?


The source (AVS, cropped) is 720x368, 23.976 fps

the problem is this, I encoded a RAW sample with x264 MeGUI with setings HQ-Slow which is equivalent to "x264.exe" --pass 2 --bitrate 724 --stats ".stats" --ref 5 --bframes 3 --b-pyramid --weightb --filter -2,-1 --subme 6 --trellis 1 --analyse all --8x8dct --progress --no-psnr --output "" ""

import fail

With the same settings but mp4 stream, the video can be imported successfully

Thanks for your help

I can't think of a good reason to recommend having x264 output raw instead of mp4. Can someone enlighten me to the reasoning behind this?

I don't really know what to tell the devs.... can you help me please?write all you know about the issue as detailed as possible in the bug report

[Doom9]

write all you know about the issue as detailed as possible in the bug reportWhich includes build number, build date (or rather: the CSV checkout date for the build) and of course the commandline. Even better, provide a raw and mp4 sample to reproduce the problem.
