If you want to use youtube-dl in addition to ffmpeg, then remember that the command youtube-dl --get-url generates a two line stream. One for the video and another for the audio.. you need a small shell script that handles both.. Try this (and notice that I have changed 4 minutes to seconds and use -t instead.) ffmpeg $(youtube-dl -g 'https://www.youtube.com/watch?v=DM-I6UugaFs' | sed "s/.*/-ss 06:06:00 -i &/") -t 240 -c copy testpassvideo.mp4 > I assumed that it would start recording 6h 6m from the start of the stream > (which is 12 hours long) and last until 6h 10m into the stream (duration 4 > minutes). > But in fact it recorded from current time and did not stop after the 4 minutes > so I had to manually stop it using the keyboard q key. > So this attempt did not go into the past as requested. > > Then I tried this: > > youtube-dl --external-downloader ffmpeg --external-downloader-args "-ss > 06:06:00.00 -to 06:10:00.00" -f 93 > "https://www.youtube.com/watch?v=DM-I6UugaFs"; > -o testpastvideo3.mp4 > > Again the recording did not stop after 4 minutes but had to be manually > stopped, > this time using Ctrl-C (since youtube-dl was the main program). > This also recorded from current time rather than from the beginning of the > stream plus the 6 hour offset > > _______________________________________________ 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".
