segfault combining rawvideo and audio

[GoogleCodeExporter]

I'm wondering whether pkt.destruct() is ever anything other than 
av_free(pkt.data).

If pkt.destruct() can be more than av_free(pkt.data) then perhaps 
ist.pkt_data_to_free should store the pkt.destruct to call later, instead of 
storing pkt.data.

FYI, I'm posting this issue in case I cannot work out a fix for myself. I may 
get back later, or talk on IRC.

It's due to interlacing scaling with rawdecoding and uyvy422, frame is not 
allocated but from the demuxer itself.

Ok - interesting...
As a workaround, I can fix the segfault by adding one EXTRA scale & format pair 
in the command line, so instead of

-vf scale=1920:1080:interl=1,format=uyvy422

(which segfaults) I can do:

-vf 
scale=1920:1080:interl=1,format=yuv422p,scale=1920:1080:interl=1,format=uyvy422


(which does not segfault)
The thought of how that 'fixes' the problem scares me...

It fixes it because the frame will "become" allocated by the filter chain in 
the middle. I think it is just a buffer "padding" issue in that particular case.

Should be fixed in 0.7.2
