I don't have a PSP to test it on (yet ) but give this profile a try:
Changes: added the lavfopts format option, removed brames x264encopts option, and added global_header option.Code:[PSP 480x272 (AVC/H264, FW > 3.30) *MODIFIED*] PixelLimit=130560 ScreenRatio=16:9 Manufacturer=Sony Playstation Portable (PSP) Res1=364x272 ResAna1=480x272 ARate=48000 ABRate=96 Format=avi moac=faac movc=x264 lavfopts=format=psp:i_certify_that_my_video_stream_does_not_use_b_frames mopts=-faacopts br=%abrate%:mpeg=4:object=2 -x264encopts bitrate=%vbrate%:level_idc=21:global_header:frameref=2:nopsnr:nossim%PASS% FileType=mp4 Quality=15 useMencoder=1 SubTitle=1 MaxVBitrate=750 ThumbNail=JPG AllowChapterFiles=0 MVolume=10 Remux=2642MP4 QualityFactor=130
I have no idea if it will work - I've just seen references on the web to this sort of problem...
AtTheAsylum, your profile works great, but the frame resolution is 480X272. What we are all looking for is 720X480 so it looks good on the TV as well as the PSP. The A/V sync issues are better with your profile! Great job.
