Bugzilla Bug 128404

The following command consumes more and more memory; after < 1 h, 512 MB Ram
are used up and lavrec crashes. The latest version (lavtools 1.8.0) still has
this problem.

<example>

avalon dvd #  lavrec -f a -i P -g 352x288 -t 7200 -q 80 -R m -l 85 -r 48000 -a
16 --software-encoding junk%02d.avi

**ERROR: [lavrec] Error reading audio: Audio task died. Reason: Error Audio
ring buffer overflow

Reopen with ebuild name and version...

ebuild name and version is:
mjpegtools-1.8.0-r1

Does lavrec somehow involve lav2wav? 
Have a look at 
http://article.gmane.org/gmane.comp.video.mjpeg.user/9226/match=mjpegtools+1+8+memory

I think we have to wait until 1.8.3 or use the CVS version.

Sorry, I meant 1.8.0.-r3 (not 1.8.3)

Have a look at #100869

That broken patch made it somehow into 1.8.0 upstream; I'm currently working on
an updated patch.

Created an attachment (id=86726) [details]
possible fix

This patch should fix it, but tested on x86 only.

I'm not sure if there are any issues with different
endian machines (like PPC) left. In case it's broken you get
only "noise" in the audio track...

*** Bug 134740 has been marked as a duplicate of this bug. ***

Patch added to mjpegtools-1.8.0-r2.

I have a report that this bug is still existing.

Can someone please test mjepgtools-1.9.0_rc1, and tell me if that patch (that
still gets applied) need to be removed.

This patch seems to be correct, and it was not included in 1.9.0_rc1
(upstream).
It has now been pushed there.
