I tried to stream H264 video outside Niagara(attached file) Looks like it is
running there:
Can you pls guide how to capture ffmpeg crash specific logs which we are facing
in Niagara?

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
