ffmpeg first segment does not have audio
5 mars 2018, par Giorgi PeikrishviliI’m recording http stream using ffmpeg. Here is my command :
ffmpeg -i https://tv-tbs-silk-front 1.adjara.com/4w/rustavi2hd/index.m3u8\?token\=376d9f864d81c7f85410ac5d3d0bde3dd6574daf-Hog86dAubE-1522939917-1520175117 -c copy -map 0 -bsf:a aac_adtstoasc -flags +global_header -f segment -segment_time 10 -force_key_frames 10 -segment_format_options movflags=+faststart -reset_timestamps 1 -strftime 1 %Y-%m-%d_%H-%M-%S.movIt makes segments as should be, but the only first segment does not have sound, others does.
Any ideas about that ?Update as suggested in comments :
Here is full outputffmpeg -i -c copy -map 0 -g 10 -bsf:a aac_adtstoasc -flags

ffmpeg trying to remove the first few seconds of video
