[FFmpeg-user] Video corruption when transcoding on new computer

2020-06-08 Thread Michael Kohne via ffmpeg-user
We use ffmpeg to transcode video from an H.264 video stream from an IP camera to an mpeg4 AVI file. On our old system (Core i7-4765T, CentOS 6, with a locally built 3.16.60 kernel. 4 cores + hyperthreading) we had no problems. Upon switching to a new system (with a Core i7-6600U, still CentOS 6,
