[FFmpeg-user] How to make FFMEPG ignore errors and keep encoding

[Bryce McLeod]

Hi,

This isn't something you can do with command line flags. If you cannot
resolve the problem with the stream then have your calling process/script
restart ffmpeg when this happens. Depending on the error checking the exit
code is usually enough.
