Are you saying that after this commit you have a x264 cli that works<br>
withouth segfaulting (either with or without --input-res)?<br>

correct, I am NOT able to reproduce a crash after the indicated<br>
revision, nor after updating to the latest libav (which now has<br>
libswscale at 2.0.0).<br>
I tested on what platforms i have available to me which is win32,<br>

Okay, so I've tried (again). I pulled x264 (no updates), compiled it,<br>
and installed it. Then I pulled ffmpeg (no relevant updates), compiled<br>
it, and installed. Then, because of back-and-forth dependencies between<br>
libx264 (x264) and libav* (ffmpeg), I compiled x264 once more and<br>
installed it.<br>
<br>
Then I did this:<br>
<br>
x264 --profile=high --preset=veryslow --level=40 --aud --keyint=100 --ref=4 --nr=1000 --bframes=8 --threads=16 --vbv-bufsize=31250 --vbv-maxrate=25000 --nal-hrd=vbr --crf 24 test.avi -o test.264<br>
<br>
Where test.avi is an avi with mjpeg and pcm audio. And then I get this:<br>
<br>
lavf [info]: 704x576p 16:11 @ 25/1 fps (vfr)<br>
resize [warning]: converting from yuvj420p to yuv420p<br>
x264 [info]: using SAR=16/11<br>
x264 [info]: using cpu capabilities: MMX2 SSE2Fast SSSE3 FastShuffle SSE4.2<br>
x264 [info]: profile High, level 4.0<br>
[1] 24101 segmentation fault x264 --profile=high --preset=veryslow --level=40 --aud --keyint=100 --ref=4<br>
<br>
Gdb says (very terse because no debug info atm):<br>
<br>
Program received signal SIGSEGV, Segmentation fault.<br>
0x00007ffff6995562 in ?? () from /usr/lib64/libswscale.so.2<br>
(gdb) where<br>
#0 0x00007ffff6995562 in ?? () from /usr/lib64/libswscale.so.2<br>
#1 0x0000000000000000 in ?? ()<br>
<br>
I checked that the proper versions of the libraries were linked and used<br>
using ldd. This is on x86_64 / amd64. I am using gcc 4.5.1 and glib 2.13.1.<br>
<br>
Adding --input-res=704x576 makes no difference.<br>
<br>
Thx.<br>
