From: Jack Lau via ffmpeg-devel <ffmpeg-devel@ffmpeg.org> To: ffmpeg-devel@ffmpeg.org Cc: Jack Lau <jacklau1222@qq.com> Subject: [FFmpeg-devel] [PATCH] avformat/hlsenc: calculate bitrate for segments with duration < 0.5 Date: Mon, 24 Mar 2025 07:13:22 +0800 Message-ID: <tencent_1D2850575A172F11274023BAB3497C3D6308@qq.com> (raw) 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.
