Capturing the 5 live video stream

[Kevin Lynch]

ok - I reread the instructions and suppressed the space Vangelis
suggested and it works

so here are the commands that work


 2004  ffmpeg -loglevel 16 -re -i
http://vs-hls-uk-live.edgesuite.net/pool_10/live/bbc_radio_five_live_video/bbc_radio_five_live_video.isml/bbc_radio_five_live_video-audio_1=128000-video=1374000.m3u8
-c copy bbc_radio_five_live_video.ts
and the remuxing of the stream
 2006  ffmpeg -i bbc_radio_five_live_video.ts -c:v copy -c:a copy
-bsf:a aac_adtstoasc bbc_radio_five_live_video.mp4


created two shell scripts
1) 5livewebcamcap - capture a feed and include the time the feed
started in the filename
2) 5livewebcamremux - create the mp4 version of the files and move the
.ts to a subfolder "done"

# 5livewebcamcap
cd /media/sf_iPlayer_Recordings/avi5livewebcam
NOW=`date +%Y-%m-%d-%A-%H%M%S`
ffmpeg -loglevel 16 -re -i
http://vs-hls-uk-live.edgesuite.net/pool_10/live/bbc_radio_five_live_video/bbc_radio_five_live_video.isml/bbc_radio_five_live_video-audio_1=128000-video=1374000.m3u8
-c copy bbc_radio_five_live_video$NOW.ts


5livewebcamremux
cd /media/sf_iPlayer_Recordings/avi5livewebcam
# and the remuxing of the stream
for file in *.ts
do
ffmpeg -i $file -c:v copy -c:a copy  -bsf:a aac_adtstoasc $file.mp4
mv $file done
done
