Hi Rahul, Are you able to provide steps and/or bitstreams which reproduce this issue using FFmpeg alone and not in Niagara Workbench? There are a number of reasons using FFmpeg 7.0.1 could crash this software which are not due to bugs in FFmpeg. Most notably, does the software actually support FFmpeg 7? This is a major version bump and so FFmpeg 7 is not ABI- or API-compatible with FFmpeg 6. All the best, Frank _______________________________________________ ffmpeg-devel mailing list ffmpeg-devel@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-devel To unsubscribe, visit link above, or email ffmpeg-devel-requ...@ffmpeg.org with subject "unsubscribe".
