Re: [CinCV] Can't render with YUV4MPEG Stream
Hello, I suggest trying mencoder. It's my swiss knife for getting video files which actually work. I've published my notes under Rendering for DVD, in my site (http://billauer.co.il/cinelerra-video-edit-quickstart.html), with the relevant part copied below (mencoder notes at the bottom): * Video and Audio are rendered separately * MPEG-2 streams can be generated directly from Cinelerra, but the manual doesn't tell you to do that. * ... maybe because it's easy to get off-standard with many GUI parameters to set. * For video, the output file format is YUV4MPEG, and check To Pipe. * Create an executable script (with #!/bin/bash) file saying: |mpeg2enc -v 0 -K tmpgenc -r 16 -4 1 -2 1 -D 10 -E 10 -g 15 -G 15 -q 6 -b 8600 -f 8 -o /path/to/output-video-file.m2v| * Note that unlike what's implied in the manual, Cinelerra doesn't pass the output file name as first argument to the script. The file name is therefore hardcoded * It does send some garbage instead. A simple trick is to end the pipe's command with a '#' which comments out the garbage * Then choose AC3 as output format, and render audio. The standard allows up to 1536 kBits/sec, so you can't go wrong with this. * Note that you can use mencoder and YUV4MPEG as well for a safer encoding. * Check the console for error messages and progress (when using mencoder) * When using mencoder, create a raw PCM audio file (Microsoft WAV is fine) and then apply the file with the -audiofile parameter. * In the script file you'll have something like: |mencoder -audiofile full/path/to/only-audio.mov -oac lavc -ovc lavc -of mpeg -mpegopts format=dvd -vf scale=720:480 -srate 48000 -af lavcresample=48000 -lavcopts vcodec=mpeg2video:vstrict=1:vrc_buf_size=1835:vrc_maxrate=9800:vbitrate=5000:keyint=18:acodec=ac3:abitrate=192:aspect=4/3 -ofps 3/1001 -o movie.mpg -| (NTSC) * Note the dash, telling mencoder to read from standard input * If mencoder complains that it cannot seek backward in linear streams and seek failed (several times), adding the |-cache 8192| parameter is likely to help. Good luck, Eli -- Web: http://www.billauer.co.il

Hellor Einar, welcome in the club of cinelerra bug hunters ;-) The issue described above is one of the most annoying strange design decisions in Cinelerra. Probably a lot of people (including myself) would welcome just to phase it out. This is true and may solve a basical problem of cin's usability Some years ago I worked on a larger patch to remove the greatest obstacles and strangenesses on the bezier automation curve handlings. This patch is not accepted into Cin-CV until today. One of the reasons is that I too tried to partially rectify these and some similar problems with dragging nodes in the trackcanvas (GUI). Would be great to merge your work (for 64 bit) with Einar's one; after doing that cinelerra cv would get a big step forward in usability for extended production Meanwhile the situation might be different, inasmuch develompment on the community version of Cinelerra is mostly stalled, I don't think this is still true by now, as long as I've been teaching for 2 years cinelerra cv (2.1), and I think that most people on this ml still consider that version of cinelerra as the stable version. And how to we all (Cinelerra community) judge the situation? Do we still intend to merge in what upstream provides, or would we be willing to stick to the Cin-2.1 codebase and in turn accept more disruptive changes? I consider the second option as the more usefull by now, in order to keep the value of the community work; and I agree that the bezier patch sould be merged with the whole 2.1 codebase as long as the Einar's changes after a short testing on other supported architectures. In order to test Einar's code I'd like him to put it into a pubblic repo.

Re: [CinCV] Can't render with YUV4MPEG Stream
Arthur, I have a script that contains: ffmpeg -f yuv4mpegpipe -i - -y -target ntsc-dvd -flags ilme+ildct -f mpeg2video $1 that I pipe cinelerra rendering to. Works for me. I guess you could use the pipe directly in cinelerra by changing the $1 to a % sign. I use a script and have several different pipe command strings in it all but one of which is commented out. mpeg2enc and ffmpeg change, or have in the past, their command line arguments so when they have updated, things that did work stopped working. If all else fails, try the documentation for the version of mpeg2enc or ffmpeg you are using to see what works. In looking at your ffmpeg -f yuv4mpegpipe -i - -y -target ntsc-dvd -ilme -ildct -hq -f mpeg2video % command, I think the -ilme -ildct may be causing the problem depending on the version of ffmpeg. My line uses -flags ilme+ildct instead which is what is required by my version.

The entire video itself will play on all players (mplayer, vlc, WMP), and I can even load it into avidemux and edit it there. Other times, none of the video (0 seconds) will load. My only suggestion might be to run cinelerra from a console window, and see if any messages are displayed - especially from the underlying codec libraries. If no one here can help with those, try the mplayer/ffmpeg mailing list. They can at least explain what the messages mean. I do have one gripe, though. With all due respect for a really great application, it is not very robust. Aside from the problems mentioned above, most of the times I have used cinelerra, I have gotten many continuous messages about file read errors - especially with corrupted frames; it easily crashes, as well as barfs up core dumps. This is not a flame, just a simple critique from observations. ken
