How to Capture stream of NBCOlympics.com

(http://stream-recorder.com/forum/showthread.php?t=13287)

Re: How to Capture stream of NBCOlympics.com

Mr. Paul,

Thanks so much for your help. Capturing in 1080p is working wonderfully.

I am also wondering whether or not -ss command will work. When I try to use it to start recording 42 min (-ss 00:42:00), ffmpeg begins downloading but with 0bytes & 0 bitrate with 00:00:00 time. Is this correct. Will it only start downloading once it hits 42 min mark?
Thanks for any assistance with this.

Re: How to Capture stream of NBCOlympics.com

As I'm downloading I had one video throw a 404 and die but the rest have been working. However I'm noticing during busy traffic hours on Comcast I get a lot of drops.

I've tried replaying the video and can't see any quality degradation in video or audio so I'm wondering if these drops get retried until the frames are delivered without quality loss in the end. Is that the case?

Re: How to Capture stream of NBCOlympics.com

If your download is getting cut off try downloading during low traffic hours. I do all my downloading after midnight

BTW has anyone found such a simple solution to downloading from BBC? I only see a convoluted rtmpdump method. I'm thinking of just recording the audio, since all I really want is the commentary. There's almost none on NBC's videos

Type in "m3u8" in the filter on top right
Start the video you want to see
Click the gear icon on bottom right of video and select the quality you want (typically 1080) and you'll see a new m3u8 file appear
Use this URL for the "-i" option of ffmpeg

cheers, mrPaul for reply my other thread about Eurovisionsports.tv
but unfortunately, the web-console don't seem to pick up anything on EVS's site. no m3u8 file. :-(

hers a sample link : http://www.eurovisionsports.tv/londo...?video_id=8503

is there perhaps another way using ffmpeg?

yea theres that too, but so far
the DL has been intermittent and unstable. :-(

Re: How to Capture stream of NBCOlympics.com

when i enter -t XX:XX:XX ffmpeg still keeps on downloading. i have to stop it myself. how i make it stop itself?

On another video i set up -ss XX:XX:XX but after a while the link timed out. I want to record certain parts of long videos but the link dies before ffmpeg gets to where I want it to start. Any way to make ffmpeg start downloading immediatley at the time I set -ss at?

unfortunately not, =(
do you happen to know a noob friendly ffmpeg user guide?
or how a noob should navigate round the ffmpeg documentation to
"earn the ropes" ?

cheers
