Re: [transcode-devel] A/V sync problem transcoding from .nuv to .mpeg

[etc etc] These changes are now committed to CVS, so try updating and compiling again (but make sure you install lzo first, and don't forget "make distclean; autoreconf -f -i"). Status report: Hey - it's working! Just a couple of surprises. It seems that you have to give the --enable-lzo option to './configure' just to get support for the .nuv import filter. This looks like a side effect of other changes, and certainly isn't obvious to a random punter. Might I suggest that someone renames --enable-lzo to --enable-nuv, as Andrew did say in the previous post that lzo was no longer an option anyway. Oh, and it seems that when you say 'lzo' you mean lzo2, it doesn't seem to compile with lzo1 (on Fc2 at least). The ./configure script maybe could be cleverer about detecting lzo2.               ------------------ Anyway - suddenly, I can transcode Nuppelvideo with no A/V sync issues any more! However, I've so far only managed to create mpeg4 AVI files using the "-y ffmpeg -F mpeg4" options. I can't seem to get "-y ffmpeg -F mpeg2video" to work, nor anything involving "-y mpeg2enc". Actually, the former generates status lines indicating that it is working, but mplayer complains there's no video in the resulting file..... The latter just barfs complaining about a missing shared library. Again, it would have been nice if ./.configure had noticed that there was something amiss with the shared library. Judging by other posts, there's been some syntax changes to the -y option in the 1.1.0 branch, maybe I just need to learn a bit more about that. Do I also see signs that as yet, 'transcode' can't produce an mpeg multiplex? I presume that (for now) transcode could produce mpeg2 video and mp2 sound as elementary streams, and I could run 'mplex' by hand to create a program stream. That's what I apparently has to do in 1.0.2 anyway. Steve.
