Re: [Mjpeg-users] jerky leaps on hardwareplayer
Hallo I just tried for the fourth time to convert a analog video to dvd. But everytime I have the same problem. I'm not sure if it's a problem with streamer or mjpeg tools. So maybe some one can help. That's what I have done: 1. streamer -t 67500 -s 720x576 -n pal -r 25 -o movie.yuv -f 4mpeg -F stereo -O movie.wav -R 48000 -p 5 -b 64 Can you try once to record with streamer and generate a mjpeg encoded Quicktime movie. The command lookes like that: streamer -t 0:30 -s 352x240 -r 24 -o movie.mov -f mjpeg -F stereo Do not use AVI because the mjpegtools ca only handle AVI up to 2GB. And use the lav2yuv and lav2wav to generate th audio and video. 2. yuvdenoise -t2 -b 3,1,710,570 movie.yuv |mpeg2enc -q4 -f8 -b9000 -np -F3 -I1 -21 -41 -r16 -N1.0 -Khi-res -D10 -s -c -P -o movie.m2v The third test with -b8000 doesn't change anything. The end result was the same. Try to drop every option excep the -f 8, 3. mp2enc -r 48000 -o movie.mpa movie.wav That one should work well. 4. mplex -S 0 -f 8 -V movie.mpa movie.m2v -o movie.mpg 5. dvdauthor -o /temp/dvdwork/dvd/ movie.mpg 6. dvdauthor -T -o /temp/dvdwork/dvd/ Viewing the result in /temp/dvdwork/dvd/ with mplayer or xine works perfectly, but when I burn the result on a dvd and try to view it with a hardware dvd player the video has jerky leaps after ~20 minutes. Tone is OK the whole time. The leaps are only in millisecond range, but they appear every few seconds. I don't have any clue what the problem could be. If you mjpeg encoded MOV files you can cut the video with glav/lavplay, and encode the part after the 20 minutes. Create a disk of that part of the movie afterwards, to get a better feeling where the problem is. From your description that problem sounds like if the card would drop a frame or so. auf hoffentlich bald, Berni the Chaos of Woodquarter Email: [EMAIL PROTECTED] www: http://www.lysator.liu.se/~gz/bernhard --- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM.

[Mjpeg-users] how to encode an MPEG from an AVI?
Hi, i did not encode any MPEGs from an AVI for a longer time. I used to use mp2enc for that, but it seems it is not in the latest distribution i use any more. I think there were some license issues with this one, if i remember correct? What could i use best nowadays to encode an MPEG from an AVI, e.g. for a SVCD or something similar? Best regards, Torsten. --- SF.Net email is sponsored by: Discover Easy Linux Migration Strategies from IBM. Find simple to follow Roadmaps, straightforward articles, informative Webcasts and more!
