Hi,
I have two problems using mencoder to encode jpg files to an avi stream.
First of all when I am using lots of files (somewhere between 2162 and 3078)
not all of them get encoded. (3078 files leads to 626 frames)
The other problem is that using the lavc encoder family leads to a
segfault in memcopy.
Please let me know if you need more info.
Best Regards
Jens
