I'm posting this bug as a reference to
because it seems that the mlt project is largely
inactive and there are no fixes to be expected.

This has been fixed in MLT now - well, sort of... there is a
bug in ffmpeg which causes the duration of the video to be
miscalculated, but the crash is resolved. Many thanks for
the feedback and apologies for the long delay.

Does a corresponding bug report exist in the ffmpeg bug db?
I haven't checked - most of their bug reports are handled
via their cvs mailing list.
They're only interested in bugs reported against CVS too,
and I can confirm that with your test file, current CVS
misreports the duration as follows:
$ ffplay -stats ~/Desktop/test.avi
Input #0, avi, from '/home/charlie/Desktop/test.avi':
Duration: 00:01:56.0, start: 0.000000, bitrate: 494 kb/s
Stream #0.0: Video: rawvideo, yuv420p, 720x576, 25.00 fps(r)
Stream #0.1: Audio: pcm_s16le, 48000 Hz, stereo, 1536 kb/s
I haven't checked if this is a general issue with all
rawvideo avi's though - it might simply be down to the tool
you used to create it - which tool was it? And did you do
anything during the creation of the file such that it might
have been truncated?
FWIW, I have incorporated the fix in the ubuntu build of the
current jah (and I hope to add an amd64 and another [other]
debian package soon).
I don't think that the vid length given by ffmpeg is due to
a bug in ffmpeg. The test vid has been produced with
avidemux 2.0.42 (and that program is quite buggy: for
example, I cannot start encoding after saving a
project....). Using mencoder to copy a small part from my
raw vid dump creates a file that is properly evaluated by
ffplay. (ffplay does not play back both versions of it, it
just gives a black window each time)
BTW: I have installed the current mlt and mlt++ cvs versions
and jahshaka 2.0rc3 still produces this SIGSEGV. For me, it
looks like the mlt lib treats the YV12 (yuv420) raw images
as yuv422 images and therefore assumes a too large frame
size. (though I have not checked that)
I'm running Gentoo. What do I need to update to get your
fix? Just Jahshaka?
Could well be an issue with avidemux then.
Which version of ffmpeg are you using? Personally, I don't
think there's much point in using it directly unless it's
the very latest svn version :-).
Ditto for mlt - you'll definitely need cvs for the rawvideo
fix (I only checked it in last night).
Cool. I can open the files now. (with the recent ffmpeg from
