[FFmpeg-devel] [PATCH v2] examples/transcoding: Fix time_base handling

The `dec_ctx->time_base` was incorrectly default set by avcodec_open2(), while `enc_ctx->time_base` was derived from `dec_ctx->framerate`. This mismatch could cause incorrect video duration in the output. This patch corrects the issue by adjusting the `enc_ctx->time_base` calculation to accoun

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

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_
