Bugzilla Bug 100869

The lavtools leak memory when writing avi files. After a few minutes they
usually take some hundred Megabytes of RAM and eventually, when all available
memory is occupied, they get killed by the kernel. Because of this it is no
longer possible to record/process anything bigger than 10-20 minutes.

Trying to record/save in quicktime .mov format helped me to circumvent the
memory leak but broke the audio track instead; Trying to use any other sound
format than 16 bit stereo obviously doesn't work. Depending on the selected
bits/channel combination you could get anything from garbled sound to almost
immediate crashes (i.e. segmentation fault or some memory corruption in glib).

The problems described here only occur with the quicktime USE-flag set. The
whole lavtools got almost unusable in this configuration with mjpegtools-1.6.2-r4.

Reproducible: Always
Steps to Reproduce:
AVI Memory leak:
Try to record an avi file by running "lavrec -s test.avi"
As an alternative you can try to convert some large quicktime move with
lavtrans, i.e. "lavtrans -o test.avi test.mov"

Quicktime crash/sound problem:
1. Try to record an quicktime file by running "lavrec -s -a 8 test.mov",
"lavrec -a 8 test.mov", or simply "lavrec test.mov".
2. If you were lucky and lavrec didn't crash, try to play the resulting file
with some media player. As an alternative you can try to convert some random avi
file with 8bit/mono, 8bit/stereo or 16bit/mono soundtrack to quicktime with
lavtrans.

Actual Results:  
AVI Memory leak:
Memory and Swap gets filled and then the program is killed.

Quicktime crash/sound problem:
lavrec/lavtrans crashes with a segmentation fault or a message that some memory
corruption happened somewere in glib. If the program didn't crash and you play
the resulting file, the sound is garbled (a few octaves to high and very noisy).

Expected Results:  
The programs should not use excessive amounts of memory when writing AVI files
and should not crash or corrupt the audio track in quicktime movies.

Created an attachment (id=64775) [details]
replacement patch file

I found out that the problems mentioned above are caused by the patch located
in
media-video/mjpegtools/files/mjpegtools-1.6.2-libquicktime094.patch
in the portage tree. It is broken in several ways, i.e. allocating/freeing
memory in the wrong places among ignoring different sample formats, among some
other things.

I finally fixed those bugs and created a replacement for that broken patch.

Calling arches. mjpegtools-1.8.0 is safe (as it does not use the patch), that
should probably be marked stable to fix this bug, as changing the patch would
anyway require a revbump losing stable.

you mean mjpegtools-1.8.0-r1, don't you?

Yep sorry, making more informative the subject, too

stable on ppc64

sparc stable.

x86 done

amd64 stable
also removing ppc since hansmi already marked it stable

Alpha? You're the last needing to stable this to be able to drop the
non-modular version.

Alpha done by agriffis. Resolving since we are last on the list.
