Hi,
maybe this is only a small one but i could not find a solution so far:
I have a problem with converting avi's to mpeg . I am recording from my tv-card (haupauge pci) to an avi file using streamer from xawtv and want to convert it using mjpeg tools to a mpeg file and burn it to a SVCD DVD.
When i record one hour with
streamer -t 1:00:00 -s 480x576 -r 25 -j 85 -f mjpeg -F stereo -o testy.avi
i get a 6 to 7Gig avi file. Next step i extract video and audio using:
lav2wav +p testy.avi | mp2enc -o testy.mp2
lav2yuv +p testy.avi | mpeg2enc -f8 -b4000 -o testy.m1v
and after that i am using mplex and dvdauthor to finalize it...
mplex -f8 testy.mp2 testy.m1v -o testy.mpg dvdauthor -o testy -v 480x576+pal+4:3 -a mp2+de testy.mpg dvdauthor -o testy -T
Now the DVD seems to look fine but only the first 17 to 20 minutes of the original material are on the final disk. It seems that after extracting 2Gig of the the 6Gig avi (~20 minutes equals one third of an hour) the
lav2yuv +p testy.avi | mpeg2enc -f8 -b4000 -o testy.m1v
stops. Now what i did was rechecking the ./configure script of the mjpeg build for large file support options but I could only find a "disable" option. Anyhow I tried the following
./configure --prefix=/usr/local/mjpeg/1.6.2/ --enable-largefile=yes
but still when I am doing the extraction of the video part the final result contains not more than 20 minutes of film sequence.
I assume that the large file support should be turned on per default ?? I do not have a problem with large files with other applications on my system (debian woody running 2.6.10) like tar , samba, dd etc. so generally spoken it should be ok. Maybe i am wrong but am i running into a 2gig issue here? Is there something missing in my ./configure script?
Sounds like the 2 GB file size limit... You could try mencoder from the mplayer package. I find it to be quite poor at recording video (doesn't seem to know how to deal with variable A/V sync issues resulting from dropped frames, so resyncing later is unfeasibly difficult), but I have always found it to be VERY good transcoding video that is already well synced into a different format (I used it for transcoding to VCD).
HTH.
