[FFmpeg-user] issue with [PATCH] avformat/hlsenc: actual segment file size and duration in segment filenames

[Christian Johannesen]

I tested new functionality that was recently added to FFMPEG to include the
segment size in bytes and segment duration in the filename. I tried
re-multiplexing a MP4 with H.264 video and AAC audio into HLS with this
feature, but only the last HLS segment has this data, all other ts segments
contained zero data.

>ffmpeg.exe -i D:\media\mix_of_clip_960x540_2128.mp4 -codec copy -f hls
-hls_time 6 -hls_list_size 5 -hls_flags
second_level_segment_index+second_level_segment_size+second_level_segment_duration
-use_localtime 1 -use_localtime_mkdir 1 -hls_segment_filename
"D:\media\mix_of_clip_960x540_2128\segment_%%04d_%%08s_%%013t.ts"
