lav2yuv cannot open mjpeg file

[Henrik]

Binary package hint: mjpegtools

After upgrade to 9.0.4 the lav2yuv program fails to open the mjpeg file.
htx@ub1:/DG$ tcprobe -i taily.avi
[tcprobe] RIFF data, AVI video

htx@ub1:/DG$ lav2yuv taily.avi
**ERROR: [lav2yuv] Error opening taily.avi

The program worked ok under 8.0.4, but after upgrade to 9.0.4 via 8.10 it failed to work.

I have attached the input file, it could be that it was the one causing the problems.

I have just reinstalled my machine from scratch with Ubuntu 9.04 and the error is still present.

The machine is an AMD64 based HP.

Running strace lav2yuv taily.avi reveals the following (only the last part):

I hope that someone can extract some information out of this, because I'm starting to get into problems with deadlines etc., and I really need this little program.
