Okay I isolated the issue, it's the audio codec, when enabled it causes ffmpeg to crash, when disabled it works fine:

Duplicate of ticket #2846

Please understand that there is nothing to fix in FFmpeg afaict (consider providing a backtrace if you disagree), you simply have to use the same (or at least more similar) parameters for first and second pass.

comment:6 Changed 6 years ago by cehoyos

Or, as I tried to explain there: It would probably be even worse if the crash wouldn't tell you that encoding went completely wrong.

Version 0, edited 6 years ago by cehoyos (next)

comment:7 Changed 6 years ago by ramitbhalla

so if I understood correctly (and tried and it works), replacing the -f rawvideo NUL with 2ndpassfail.mp4 in the 1st pass works fine (no crash).
Are you saying that the audio format difference (since NUL causes audio to be disabled) is what is causing the sync/crash?

If so, how does one use NUL in the first pass to speed things up?

comment:8 Changed 6 years ago by ramitbhalla

got it, I used -f mp4 and it worked fine. I guess -f rawvideo was changing muxers (which caused the audio to be disbaled in 1st pass) hence causing 2nd pass to crash since audio was present with the mp4 muxer.

Is this correct?

Also I didn't any performance improvement by using -f mp4 NUL vs xyz.mp4 - is that the right behavior?
