Short description of error

Using H.264 and PNG codec, causes a segmentation fault.

Exact steps for others to reproduce the error

  1. Open a new .blend file
  2. Under Render tab, and under the Output header, set file format to H.264
  3. Under the Encoding header, set Codec to PNG.
  4. Press Animation in Render tab. It will either give "Error: Specified pix_fmt is not supported" or have a segmentation fault. If you get the error, hit Animation again. It will eventually have the segmentation fault (and crash).

(Blender 2.69 r60991 does not seg fault, only gives that error message)

Here is a .blend with the first 3 steps completed:

Upon crashing it wrote out this .crash.txt file:

It seems to culprit is RGBA. If set this to RGB i have no issues.
On osx the error with RGBA is:
Error: Error writing frame

Looks like it's fixed in rB2175302. At least buildbot builds doesn't crash for me anymore.

Thanks for the report, closing it now!

Great, thanks! The problem is gone for me in the latest build too.
