I am unable to figure out from that link how to get the 1080p URL. I have tried multiple chrome plugins that track all HTTP requests and the Inspect Element option's Network tab to no avail.

I can usually find this:
https://video.media.yql.yahoo.com/v1/video/sapi/streams [...]

And this:

text/javascript;charset=utf-8

but not the next part

Code:

"host":"https://ci-b679e955e2-2e7308d8.http.atlas.cdn.yimg.com","path":"/livenation/3/5/b2e360f7-b157-478c-a2a2-4dae626f4550_mEzg2xNxDcVzbfkc3dpDMV_fckBjsmhOijcX0UHckRGvjpo0ZAyZzj-4ZGY84AAbxgbIEG-JV2w-_11_0.m3u8?a=[...]","width":1920,"height":1080,"bitrate":4192,"duration":245,"mime_type":"application/vnd.apple.mpegurl"

I would like to get the 1080p source for this:

https://screen.yahoo.com/live/event/david-crosby

Any help would be appreciated. Thanks

EDIT: I am now trying Wireshark but it seems overkill.

As far as I can see, there is no 1080p source. Only 720p:

Code:

https://yahoo-live.hs.llnwd.net/livenation2p.m3u8

Code:

livestreamer "hlsvariant://https://yahoo-live.hs.llnwd.net/livenation2p.m3u8" best -o 01.ts

Code:

Hi everyone
I also think that there is only a 720p live streaming (and for the 24 hours replay), with a bitrate slightly higher than 6Mbps, and the 1080p links that you can find sniffing are from the other videos in the page, ie, currently in the link https://screen.yahoo.com/live/livenation, below the live streaming frame, there is a section called "Moments you may have missed", and that videos have 1080p links, but with lower bitrate than the 720p live streaming.

Thank you! Indeed it looks like there isn't a 1080p link. The one surya posted is just one of the other videos.

It looks like there is no way to start recording from the beginning without actually waiting for the video to loop to the beginning because the m3u8 file gets constantly updated with a list of 10 ts sub-parts. I guess you could try to figure out where it starts and ends by guessing and looping through all the numbers but probably not worth it.

There is a Lindsey Stirling concert tonight on Yahoo Screen. I have been trying to figure out what the base URL is for a bit, but I cannot seem to find it. Can anyone take a look at this?

https://screen.yahoo.com/live/event/lindsey-stirling

https://screen.yahoo.com/live/event/lindsey-stirling

720p

.ts format

Code:

livestreamer "hlsvariant://https://yahoo-live.hs.llnwd.net/livenation1p.m3u8" best -o lindsey-stirling.ts

or

Code:

ffmpeg  -i "https://yahoo-live.hs.llnwd.net/livenation1p.m3u8" -c copy lindsey-stirling.ts

.mp4 format

Code:

ffmpeg  -i "https://yahoo-live.hs.llnwd.net/livenation1p.m3u8" -bsf:a aac_adtstoasc  -c copy lindsey-stirling.mp4

perhaps in 1080p quality, but I do not have the courage to search.
and I think the trick of surya987 does not work anymore

Edit: Nevermind what I said before. It seems like yahoo might've changed things a little bit with their streams as they air live, where the URLs are longer and can't have the filenames manually changed to download a different segment or switch the quality number. Then when it goes to a looped replay and it's no longer live, the URLs go back to the much-shorter URLs that can be manually changed and batch-downloaded. Does anyone know what I'm referring to? I realize that ffmpeg and livestreamer both work with m3u8 files regardless, live or replay, but I'm talking about downloading the individual .ts segments.

I don't remember it being like that before, even as recently as last month. When it aired live, the URLs were the same no matter what, always the short format, which can be batch-downloaded by simply adjusting the numbers in the filename. That no longer seems to be the case when it's playing live, or even during the beginning of the first replay. I think maybe after midnight EST is when the URLs change back to the short format. Another difference to prove I'm not crazy.. when the URLs are the longer format, the segments are roughly 8 seconds each, instead of 10 seconds per segment when the URLs are shorter. Therefore, the segment filesizes are also different. The 10 second ones average about 7.5 MB per segment at the highest 720p setting, while the 8 second ones are less than 6 MB per segment.

If anyone else has noticed this about the streams as they air live or knows what I'm referring to, I was wondering if it's possible to batch-download the individual segments when they have the longer URLs / shorter segment size. I was also wondering how long it's been like this because I thought it used to always be the same whether the stream was live or not. Thanks a lot in advance for any help.
