H264 Encoding Broken with pthreads > 1 on windows

Reported by: DJX Owned by:
Priority: important Component: undetermined
Version: git-master Keywords: Win32 Win64 H264

Description (last modified by cehoyos)

Summary of the bug:
Encoding H264 appears to be broken on both Win32 & Win64. The encode goes along for a while then pauses then continues again. It will do this repeatedly until eventually it hangs forever with CPU utilization at 0% and you have to kill the process.

How to reproduce:

comment:2 Changed 5 years ago by burek

did you try updating your libx264?

comment:3 Changed 5 years ago by DJX

The version of libx264 compiled into the binary is: 20120508-git-999b753.
I am using the builds provided here:

Thank you.

comment:4 Changed 5 years ago by DJX

Just an update:
This issue might be related to the forum thread here:
There, one user sites the following commit as a possible cause to the issue:

commit e4e30256f87f177decf59b59e923d05ef64147df
Author: Janne Grunau <janne-libav at>
Date: Sun Dec 25 11:45:05 2011 +0100

threads: default to automatic thread count detection

Another user on that thread says "compiling with --disable-pthreads rather than --disable-w32threads" fixes the issue.

comment:5 Changed 5 years ago by cehoyos

Can you confirm that the problem does not happen with -threads 1 ?

comment:6 Changed 5 years ago by DJX

I confirm that the problem does not happen with -threads 1.
...just encodes at a lovely 20 fps...

comment:7 Changed 5 years ago by cehoyos

  • Priority changed from normal to important

I suspect this is important.

comment:8 follow-up: Changed 5 years ago by arad85

The problem goes away when you compile with Win32 threads. This is being looked at by Roger Pack - he is working with the pthreads team to identify the cause. I haven't seen any update for around a week now.

comment:9 Changed 5 years ago by rogerdpack

as a note I'm able to reproduce this with -threads 1 with "later" builds but not those around jan 1 2012. However, with -threads 6 I'm able to reproduce this with basically any version, so my guess is it's a bug in the internal pthreads library in use. Still investigating...

comment:10 Changed 5 years ago by michael

  • Summary changed from H264 Encoding Broken to H264 Encoding Broken with pthreads > 1 on windows

Any news on this ? its quite a while ...

comment:12 Changed 4 years ago by DJX

While I don't know if current Zeranoe builds are using pthreads, I can say that my current FFmpeg, from Zeranoe, is working correctly. During the following encode, FFmpeg was using all available cores.
