Thanks for this example, I have now extracted parts of the code and put it into
my download script as a way in order to find the m3u8 URL at the beginning of
the download:

VIDEOURL="https://msnbcdailyshows.com/"
ggid=`curl $VIDEOURL | grep -o -e "https://goodgame\.ru/player?[0-9]\+" | grep
-o -e "[0-9]\+"`
VIDEOSTR="https://hlss.goodgame.ru/hls/${ggid}.m3u8"

And then I have used these for ffmpeg as follows:

CMD="ffmpeg -hide_banner -user_agent \"Mozilla\" -i $VIDEOSTR -vf
scale=w=-4:h=480 -c:v libx264 -preset fast -crf 26 -c:a copy -t $CAPTURETIME
$TARGETFILE"
eval $CMD

I could not use the resolution flag you showed because it did not work properly
for me. But the re-formatting code was already done and working so I kept that
instead.

Thanks again!
