Description

There seems to be a problem with the FFmpegFrameRecorder that worked fine from 1.5.1 to 1.5.3. It seems that there is no problem if the codec is mpeg4, but when I use h264, Java will be crashed. I would appreciate it if you could let me know if there is a workaround.

A fatal error has been detected by the Java Runtime Environment: SIGSEGV (0xb) at pc=0x00000001c7c9ed92, pid=6835, tid=0x000000000001e60f

JRE version: Java(TM) SE Runtime Environment (8.0_172-b11) (build 1.8.0_172-b11) Java VM: Java HotSpot(TM) 64-Bit Server VM (25.172-b11 mixed mode bsd-amd64 compressed oops) Problematic frame: C [libavcodec.58.dylib+0xfc2d92] aver_isf_history+0x2ae3a2

Contributor guide

Research direction
