If Cinelerra does get this ability, I probably won't use it that often. The reason is, I need to convert to several different file formats from the same source video. Rather than render several times, it makes more sense for me to render separately to YUV4MPEG and WAV files, then use ffmpeg: (ignoring aspect ratios and other options for simplicity here) ffmpeg -f dvd -i file.yuv -i file.wav dvd.vob ffmpeg -f vcd -i file.yuv -i file.wav -s 352x240 vcd.mpg ffmpeg -f mov -i file.yuv -i file.wav -s 320x240 video-ipod.mov etc... The end result is timesaving, as ffmpeg is very quick to compress these files. However, I also agree that the MPEG-PS encoding feature needs to be added into Cinelerra - I've even made an attempt to work on it myself. However, I seriously doubt I'll be able to finish it in a month by myself - it might be a week of work for Andraz, but for someone who isn't intimately familiar with the internals of Cinelerra and AV multiplexing, it's a learning curve. I do however think it is vitally important to get one working encoder using libavformat/libavcodec to produce muxed files. When this happens it will be easy to use that code as a basis to encode many additional input/output formats (taking advantage of the avformat library) that probably wouldn't be on the radar otherwise, but could make Cinelerra more popular with other groups of video enthusiasts (for instance , people interested in video podcasting, SWF video, PSP, etc), hopefully leading to more developers getting involved long-term. So, I'm motivated to put some serious work into a libavformat-based MPEG-PS encoder, but I need help, mostly in getting the rough framework designed. Anyone else working on this want to collaborate? -Joe _______________________________________________ Cinelerra mailing list [email protected] https://init.linpro.no/mailman/skolelinux.no/listinfo/cinelerra
