srt-yt can stream a whole video supported by yt-dlp to a srt receiver
ether obs studio or using srt-live-transmit and mpv with the srt-mpv script
srt-trim lets you stream a clip with a start and end point from any site supported by yt-dlp
to a srt receiver which could be obs studio or using srt-mpv
srt-trim uses ffmpeg to create a start and a to point
with the -s and -t options
you define a start point and then the amount of time after the start you want to stream for
to stream a video from 1 minute for 1 minute the command would look like this
with the default ip and port define in the script which you can change
Code:
srt-trim -u 'https://www.youtube.com/watch?v=dQw4w9WgXcQ' -s 00:01:00 -t 00:01:00
or over ride the default ip and port with the -i and -p options
Code:
srt-trim -i 192.168.1.131 -p 6882 -u 'https://www.youtube.com/watch?v=dQw4w9WgXcQ' -s 00:01:00 -t 00:01:00
so you dont set the -t option to 00:02:00
that would record from 1 minute for 2 mintues
thats just the way ffmpeg works
dont blame me
to make things easier i created a script that allows you to put in the start and end times
and then it will give you the duration for the -t option
Code:
calculate sexagesimal duration by subtacting end time from start time
sexagesimal-time -s 00:00:00 -e 00:00:00

the srt-trim script has a default ip and port set
so you can just edit the script and change those
you can also over ride the defaults on the command line
Code:
#===============================================================================
# defaults
#===============================================================================
# default ip
ip_default='192.168.1.131'
# default port
port_default='6882'
Code:
srt-trim -i ip/dns -p port -u input -s 00:00:00 -t 00:00:00
you can create a media source in obs studio that acts as a receiver for the srt stream
Code:
srt://192.168.1.131:6882?mode=listener&latency=1000&timeout=500000
remember to open a udp port with pf
in the above example im using port 6882
and then set obs to bind to a specific ip
srt-trim with obs studio as the receiver
using the default ip and port in the script
Code:
srt-trim -u 'https://www.youtube.com/watch?v=Wmc8bQoL-J0' -s 00:01:00 -t 00:01:00
srt-mpv as the receiver
