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 :)
