I'm getting the same segfault with my mingw builds.<br>Higher the lookahead, the less bframes it needs to crash?<br><br><a href="http://pastebin.com/f2b76078c">http://pastebin.com/f2b76078c</a><br><br><div class="gmail_quote">

../foreman_cif_352x288.yuv --progress --pass 1 --threads 4<br>
still seg faults on mingw<br>
<br>
it's the exact same seg fault that i reported from v13... so check my<br>
report from there for the details.<br>
<br>
at 9 bframes, it's working fine,<br>
but when i raise it to 10 and higher it starts seg faulting on b-adapt 2.<br>
haven't seen problems with b-adapt 1.<br>

> Alright - thanks to all those who found yet a few more bugs, and to Dark Shikari who continually insisted it was a bug in my code, and not the pthread_cond_wait library that was causing it to go slower than the old usleep version. Please find attached yet another updated patch - this one is back to getting our 6-10% speed gains - settings and CPU count dependent. I am getting 10%+ on a dual core system with b-adapt 2. I think I have all the bugs (16 frames @ b-adapt 2, and >8 threads == deadlock) out of this one, but again encourage folks to test on various platforms and settings. FWIW: the speed problem was that I was blocking the input queue while in slicetype decide, thereby stalling the encoding threads.<br>
