Recording the BATC streamer

You can record a BATC streamer channel on your local PC using ffmpeg.

First you need to install ffmpeg - details elsewhere on this forum.

The basic command is:

ffmpeg -i rtmp://batc.org.uk/live/<streamname> -c:v copy -c:a copy -f mp4 recording.mp4

You can also record on a Portsdown. ffmpeg is already installed, so you just need to use the command:

rpidatv/bin/ffmpeg  -itsoffset 00:00:1.0 -i rtmp://batc.org.uk/live/<streamname> -c:v copy -c:a copy -f mp4 recording.mp4

You will find "recording.mp4" in the directory that you called the command from. Note - adjust the itsoffset number (final digits are seconds) for best lipsync. The value above seems to work perfectly on a Raspberry Pi 3.
