Hi Guys I am having a bit of a problem seeking a HLS live stream.
I have a HLS live stream running, that can run up to 18 hours a day. (For now with my test its just 10 minutes). With this live stream I want to be able to say create a Video by specifying the start time and duration of the video I want to create. For my Test, I want to start 10 seconds after the start of the Live Stream and record for 10 seconds. ffmpeg -y -loglevel info -re -ss -00:00:10.0 -i http://cdn.smartvideo.cointelvas.co.za//platform_3/Live/430A222A128A41CACEAC2E47986389E9/430A222A128A41CACEAC2E47986389E9_Main.m3u8 -t 00:00:10.0 test.mp4 The command above works, but it starts recording from 10 seconds after I started the command and not 10 seconds from the start of the stream. Below is the output for my test.
