Short description of error
blender crashes while rendering animation into a video file. Cycles. Mp4 h264 (haven't check other codecs yet)
It renders some amount of frames, maybe about 40 on last build then crashes. Rendering into png sequence works fine. Rendering into a video file (mp4, h264) from image sequence works fine either.
Rendering same file with same settings worked fine till about 16th May, then started to crash on every new build

Exact steps for others to reproduce the error
open file in attachment, press ctrl+f12.

Brecht Van Lommel (brecht) triaged this task as Needs Information from User priority.

Please simplify the .blend file as much as possible so that it still crashes. Reduce samples, resolution, disable denoising if not needed, etc. We are not going to do hours of rendering to reproduce a bug unless absolutely needed.

Indeed, here is a copy 640x360p with no denoising and 1 sample.


It has crashed on frame 60 or so this time on 2.8 last build ( commit date: 2019-05-31 22:45, hash: rBcc600de6695a) BUT! I can't reproduce it when trying to write debug logs by running "blender_debug_log.cmd" It won't crash.

No more crashes while rendering this file on today build - hash: 12da679fa094
So problem is probably solved
