I don't know how to run sliced threads instead of frame threads with
ffmpeg (the application). I assume I would also need an -enable-w32thread
build?
Also I cannot provide any meaningful backtrace as I'm on windows and
cannot build ffmpeg. I compiled the w32thread.c class in my windows
project and called ff_thread_init, before the usual avcodec_open.
The FF_SLICE_THREAD option only seems to call the "execute" function at
all if I encode the file with the options, -slices 8 -tune fastdecode, if
I don't provide -tune fastdecode then it won't call the execute function
at all.
