Re: [Mjpeg-users] Fast Forward with mpeg2enc encoded dvds
No, definetly not the authoring tool or the multiplexer. I tried different mpeg streams with different authoring tools. The NAV VOBUS seem to be ok anyway when skipping to chapters, quality is good as well. The only thing is the fast forward scan. regards Clemens Am Mittwoch, den 07.12.2005, 16:22 -0800 schrieb Steven M.

[Mjpeg-users] Fast Forward with mpeg2enc encoded dvds
Hello, My standalone DVD Player (Grundig GDV 130) has problems with mpeg2enc encoded dvds. To be more precisely, the fast forward scan does not work. When doing a 2x FF, the player continues with normal speed but without sound. When doing a 4x FF, it does basically the same as at 2x With 8x, 16x, 32x 62x I get some fast forward, because the player begins to skip larger sequences. When playing a standard dvd, the 2x FF brings real 2x speed video, without skipping (looks smooth). I fiddled around with mpeg2enc options, espacially with --sequence-header-every-gop and --closed-gop, but it did not help. One example: transcode -i *$i*avi -x mplayer,mplayer -y mpeg2enc,mp2enc -F 8,"-b 9000 --interlace-mode 0 --sequence-header-every-gop --closed-gop --keep-hf --force-b-b-p --custom-quant-matrices tmpgenc --multi-thread 2 -2 1 -4 1 -q$QUAL " -Z 480x416 --post_clip -80,0 -M 1 -b 160 -n 0x55 --export_asr 2 -o colt.$i Any Hints?
