Summary

0001212: 2 pass rendering H264 always failed

Description

When I render a project using profile "H.264 .....k 2pass" it always failed at the end with error:
melt: encoder/slicetype.c:706: x264_slicetype_analyse: Controletest 'h->frames.b_have_lowres' faalt

When I render the same project using profile "H.264 .....k" 1 pass it don't fail. It doesn't matter wich profile I use, tested with 6000k and 10000k and 25000k. It only fails with 2 pass profiles.

Steps To Reproduce

Render a project using a 2 pass H264 profile.

Additional Information

It happens with latest ffmpeg svn. With ffmpeg r20024 (from suse packman repo) it renders fine.

(0004164) assem046 (reporter) 2009-10-14 09:29	I don't think it is the same as 1197. At the end of the second pass, it says "Rendering of .... aborted, resulting video will probably be corrupted. Yesterday, I tried rendering with an "MPEG-4 25000k 2pass" profile and it finished correctly. So maybe it's an ffmpeg x264 issue but I don't know. Also with x264 there is an audio delay of 1 second in the rendered movie. This don't happen when I rendered with "MPEG-4 25000k 2pass" profile.

(0004174) ddennedy (developer) 2009-10-18 06:49	There were some major changes in x264 recently and then in FFmpeg's integration of x264. I had to add some options in the export profiles in the 0.7.6 release to even get any x264 encoding to work with these recent versions. Now, it seems there are some other problems. I just tested successfully here 2 pass at 200K and 6000K with FFmpeg r19873 and x264 r538 (build 67). Yes, I know this is not a very recent version of x264. In debugging the problem with recent versions I had upgraded temporarily and then downgraded. This is just informational for now. I do not know exactly when I will get around to updating and retesting. I might wait a while to see if things settle down or shake in FFmpeg.
