Hi,

I'm facing some mp4box muxing issues, I get glitches at random positions while watching on PC and PS3,
after finding a glitch on 1st playback I remuxed the video with no sound to check if it was an encoding problem,
I then checked at the exact position I've seen the glitch and there was no problem anymore,
I muxed the thing with the sound for the 2nd time and it was gone too, but other glitches appeared at other positions ...
I verified again without sound and again it was not an encoding problem,

I'm using this mp4box version :
MP4Box - GPAC version - 0.4.5-DEV - compiled by Kurtnoise - Sep 14 2007

I'm using a 250kbps 5.1 aac file and the video was encoded like this:

x264-988.exe --pass 2 --bitrate 4200 --level 4.1 --vbv-maxrate 22000 --ref 6 --mixed-refs --no-fast-pskip --partitions all --bframes 4 --b-pyramid --b-rdo --bime --weightb --deblock -2:-1 -deadzone-inter 5 --deadzone-intra 5 --subme 7 --8x8dct -merange 24 --me umh --threads auto --cqmfile "matrix/Prestige.cfg" --psy-rd --progress --aq-strength 0.5 --no-dct-decimate -no-psnr --no-ssim --output thevideo.264 ironman.avs

then muxing like :

mp4box -fps 23.976 -add thevideo.264 -add thesound.aac something.mp4

Do you guys know something about such problem ?
I'm wondering if the --vbv-bufsize option could be part of the problem as I'm not using it

Thanks in advance :)

wrong forum...

anyway,
which players did you use on PC ?
which A/V decoders did you have ?

try with a new MP4Box build or with an other mp4 muxer...

I'm using MPC with last ffdshow release on PC, but as I said I'm getting the same problem on PS3,
I'll try some newer mp4box build, can you propose some other muxer ?

MP4Muxer with mp4creator, gdsmux from haali package filters...

Thanks man,
but I've been testing those ones with no success :'(
with gdsmux I can't input directly a h264 it says it can't find a filter or something, so I used a mp4 muxed with mp4box or mp4creator as input, so I basically remux it, but the final thing loses synch with playback,
with mp4box I'm getting some errors / warnings and the final mp4 is not playable on MPC, it starts but doesn't play, I can only seek thru it :/,
I'll have a look at the options.
