[FFmpeg-devel] [PATCH] avformat/hlsenc: calculate bitrate for segments with duration < 0.5

[Jack Lau]

The previous code sets the bitrate to be calculated only when duration>0.5, which is obviously not general enough.

In some scenarios, we may need to set hls_time<0.5, then the generated segments are all <0.5. At this time, because the bitrate is not calculated, max_bitrate is empty, and ff_hls_write_stream_info cannot write stream info normally, causing master_pl to be unavailable.
