MP4Box created files won't play in Quicktime/Itunes (error -2014 incorrect duration)

[jonathonsunshine]

howdy yall

I want to make a batch file to create iPod compatible mp4 video files from AVI s.

If I make a Avisynth script, a really basic one, like


directshowsource("myvideofile.avi")

and then use it as the video and the audio source in MeGui it works fine. I try to take the commands from MeGui's log and put them in a batch file, it SEEMS to work fine, the file plays ok under MPC or VLC but quicktime says "Error -2014: the movie contains an incorrect duration (myvideofile.mp4)"

here are the commands i use (i have separated them out from batch file but I have posted the complete contents of the batchfile and the avisynth script at the bottom)

for creating audio

"F:\AA - Video Audio Encoding Scripts\Programs\bepipe\bepipe.exe" --script "directshowsource(^myavifile.avi^) .convertaudiotofloat .normalize .convertaudioto16bit" | "F:\AA - Video Audio Encoding Scripts\Programs\NeroAAC\neroAacEnc_SSE2.exe" -q 0.4 -ignorelength -if - -of "F:\AA - Video Audio Encoding Scripts\ipod\ipodaudio.mp4"



for creating video

"C:\Program Files\megui\tools\x264\x264.exe" --crf 20 --level 3 --no-cabac --partitions p8x8,b8x8,i4x4 --qpmin 16 --vbv-bufsize 1500 --vbv-maxrate 1500 --me umh --merange 12 --threads auto --thread-input --sar 1:1 --progress --no-psnr --no-ssim --output "F:\AA - Video Audio Encoding Scripts\ipod\ipodvideo.mp4" "F:\AA - Video Audio Encoding Scripts\ipod\ipodvideo.avs"


and then muxing them together

"C:\Program Files\megui\tools\mp4box\mp4box.exe" -add "f:\AA - Video Audio Encoding Scripts\ipod\ipodvideo.mp4" -add "f:\AA - Video Audio Encoding Scripts\ipod\ipodaudio.mp4" -tmp "f:\AA - Video Audio Encoding Scripts\ipod" -new "f:\AA - Video Audio Encoding Scripts\ipod\ipodvideo-muxed.mp4"

the file appears to be fine in MPC or VLC but quictime gives that error code and iTunes acts like it doesn't exist. (IE I drag and drop it on my ipod and there is no response.

Any ideas appreciated.

Hi, that's a known problem with mp4box. See this thread (http://forum.doom9.org/showthread.php?p=1126702#post1126702) and this (http://forum.doom9.org/showthread.php?p=1146232#post1146232) for a solution.

Generating QuickTime compliant muxes with MP4Box can be a "hit-and-miss" affair.... I suggest you try using Crypto's MP4Muxer instead.

EDIT: Looks like Crypto beat me to it....

It seems that MP4Creator can only handle elementary streams. Which in itself isn't an issue but it seems it needs to be told the framerate of h264 streams ? Is there away to use it with muxed streams already ?

Or alternativly, can someone tell me what MeGui is doing that I'm not ?
