Describe the bug
After frequently pushing videos successfully, it often happens that when the player plays the HTTP-FLV stream, SRS does not push the video stream.

Version

Frequent pushing of video streams, video publish successful, HLS video can be opened.

Expected behavior
However, the HTTP-FLV video cannot be opened.

Screenshots

Additional context
After examining the SRS logs, as shown in the image above, it was discovered that the stream was abnormally terminated before the publish hook callback succeeded. This resulted in the HTTP-FLV connection showing active=0. By modifying the SrsLiveSource::stream_is_dead function in the srs_app_source.cpp file to return failure when stream_die_at_ == 0, the aforementioned anomaly was not reproduced.
