FFMPEG needs to be updated

[kkartaltepe]

You should update the ffmpeg binary as trying to encode 2 pass with multiple threads fails with the version packaged. Updated ffmpeg binary encoded beautifully with multiple threads

Even when using the latest ffmpeg build from http://ffmpeg.zeranoe.com/builds/ I crash with multiple threads.

What version are you using?

[kkartaltepe]

ffmpeg version N-63378-g1d36def
built on May 22 2014 22:08:41 with gcc 4.8.2 (GCC)

is working for me, however trying the newest build from zeranoe (built on the 24th) is again broken for me as well. Seems I just got lucky when I updated.

Ahh, I think the FFmpeg you use should be the same as your given architecture. Just did a quick check downloading from http://ffmpeg.zeranoe.com/builds/win64/static/ and the corresponding win32. All win64 compiled libraries work fine on my win8.1 64-bit machine while the 32-bit libraries crash on multiple threads.

Oh, that sucks.

N-62162-gec8789a is working for me too, not had issues with multi-thread 2-pass with any ffmpeg though

My fork now supports threaded encoding. Thanks for pointing out why threads didn't work.
