Hi everyone, I have an srt stream running 24/7, at some point in time I'd like to start an HLS stream that has as its input the srt stream.
Now, the HLS stream could go down for arbitrary reasons and I am fine with that, it should be able to be restarted and keep going, however because I will be logging some events that take place at a point in time, I need to be able to refer to that point in time regardless of when the HLS stream started. This has led me to using unix epoch as a starting offset, specifically: ` ffmpeg -re -i srt://$url/?latency=20&mode=caller <http://10.21.6.126:9001/?latency=20&mode=caller> -map 0:v -map 0:a -hls_list_size 0 -master_pl_name stream1.m3u8 -strftime 1 -hls_segment_filename /core/data/stream1/%Y%m%d/segment-%s.ts -strftime_mkdir 1 -output_ts_offset $(date +%s) -hls_flags program_date_time /core/data/stream1.m3u8 ` Using ffprobe, I am able to verify that pts time is correct and gets incremented correctly: ` ffprobe -show_packets $url ........ [PACKET] codec_type=audio stream_index=1 pts=83020451563104 pts_time=1729592740.898000 dts=83020451563104 dts_time=1729592740.898000 duration=N/A duration_time=N/A size=344 pos=9420493 flags=K_ [/PACKET] ..... ` pts_time and dts_time look correct, same for the rest of the a/v streams. Now I want to seek on that hls and cut chunks out of it: ` ./ffmpeg_g -y -ss 1729592740.898000 -t 2 -seek_timestamp 1 -i https://10.21.6.110/stream1.m3u8 /tmp/test123.mp4 ` I am getting `could not seek to position 1729592740.898` and I end up with an improper mp4 cut from live instead from the right timestamp. Am I misusing the cli somehow here? Looking forward to hearing your thoughts Kind regards, George Daramouskas _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
