1 | initial version |
It looks like this issue is specific to certain newer versions of ffmpeg which are incompatible with the 2.4.x branch of OpenCV. However, I have successfully used Opencv 3.0.0 beta to write videos with the X264 FourCC.
What exact version of ffmpeg break the OpenCV compatibility is still a mystery however. I'll be trying out various versions and report back if I find the culprit.
