Hi Anne,
im using the last version of mjpegtools 1.8.0-2 in ArchLinux
(http://archlinux.org/packages/search/?q=mjpegtools).
I tried to join videos in several ways:
1- Using avimerge from transcode package:
$ avimerge -i PiratesOfSiliconValley.cd1.avi
PiratesOfSiliconValley.cd2.avi -o PiratesOfSiliconValley.avi
With this i get sync problems after 30-40 mins on the output video.
2- Using lavtrans (as described in mjpegtools manual, Join Videos section):
$ lavtrans -o stream.avi -f a record_1.avi record_2.avi record_final.avi
With this i get the 2Gb max limit problem, obviously because lavtrans
doesnt encode the videos, just join them in a new avi. Is possible to
make lavtrans avoid 2gb complaining?
3- Last try with cat and mencoder:
cat video1.avi video2.avi> tmp.avi ; mencoder -ovc copy -oac copy -o
final.avi tmp.avi
This way is very unstable and seems to have problem when traying to
join more than 2 files.
Because of this I want to avoid spliting and joining process, fixing
the problem of the 2gb limit. Any idea?
Regards,
