[FFmpeg-user] FFmpeg HLS Output Blank During Live Stream — Possible Causes?

[Vedant Bhugul]

Hi FFmpeg team,
During a certain period, the HLS output (i.e., .ts segments and .m3u8
playlist) remained blank for every live stream attempted. However, the .flv
output stream continued to function normally. For each affected session, we
had to manually terminate the FFmpeg transcoding process—only then did the
HLS output recover and begin functioning correctly. The issue resolved
itself after this period and has not reoccurred since. It also remains
unreproducible.

Note: Unfortunately, I do not have the FFmpeg logs from the time of the
incident.

I have attached the code-snippets.txt file for your reference.

I tried adding delays both in the transcoding server code and on the ingest
server side to see if it would help reproduce the issue, but none of these
attempts had any effect. The problem did not occur again and remains
unreproducible.

*I would appreciate any guidance or assistance in identifying the root
cause of this issue* to ensure it does not recur in the future.

Best Regards,
Vedant
