Why not AdobeHds.php can't download NBC ‘meet the press’, but livestreamer can

[charmsoya]

Hello guys, this is my first time to try to download a HDS stream. If there is any error or incorrect, please point out .


What I want to download is ‘Meet the Press’ whose address is

http://www.nbc.com/meet-the-press/vi...121#vc210121=1

I found its corresponding HDS f4m is

http://nbcmpx-vh.akamaihd.net/z/vide...hd core=3.5.0

Then I use the latest AdobeHds.php to download,

php AdobeHDS.php --manifest "http://nbcmpx-vh.akamaihd.net/z/video/641/943/160226_2992970_Meet_the_Press__Feb__28__2016_mpx_, 1696,1296,896,696,496,306,240,150,64,.mp4.csmil/manifest.f4m?hdnea=st=1457256438~exp=1457269068~ac l=/z/video/641/943/160226_2992970_Meet_the_Press__Feb__28__2016_mpx_* ~id=28361036-d540-4481-a749-b4e0d5b2afe9~hmac=5d735e7977c814952d922706f5df0cd4 ea702d1a0b055f81578403ab150f8f03&g=SEKVBLWCWDJO&hd core=3.5.0"

But the output is "Access Denied! Unable to download fragments."

After trying for many times, it still didn't work, so I had to use 'Livestreamer', the command line is

livestreamer "hds://http://nbcmpx-vh.akamaihd.net/z/video/641/943/160226_2992970_Meet_the_Press__Feb__28__2016_mpx_, 1696,1296,896,696,496,306,240,150,64,.mp4.csmil/manifest.f4m?hdnea=st=1457256438~exp=1457269068~ac l=/z/video/641/943/160226_2992970_Meet_the_Press__Feb__28__2016_mpx_* ~id=28361036-d540-4481-a749-b4e0d5b2afe9~hmac=5d735e7977c814952d922706f5df0cd4 ea702d1a0b055f81578403ab150f8f03&g=SEKVBLWCWDJO&hd core=3.5.0 'pvswf=https://player.theplatform.com/p/NnzsPC/widget/select/media/guid/2410887629/2992970?fwsitesection=nbc_nbcnews_meet_the_press_v ideo_v15&excludeSharing=true'" best -o meet_the_press.flv

And it works and successfully downloaded the tv program.


Now I want to inquire, where is the problem of AdobeHDS.php? Is it caused by my wrong parameters or some others.

Which browser are you using? On Firefox the file is getting sent as an Apple HLS stream for me, which is working in both FFMpeg and Livestreamer.

Try using the "HDS Link Detector" Firefox add-on. you seem to be missing the --auth parameter. it will automatically capture all the required parameters. I am also getting only HLS (.m3u8) links not HDS (.f4m).

try us proxy this link http://link.theplatform.com/s/NnzsPC/media/lxIm5XHPMSQC?player=Onsite%20Player%20%28Universal %29&policy=43674&formats=m3u,mpeg4&format=SMIL&emb edded=true&tracking=true

Special thanks for all of your replies. I will try it later.

I didn't use firefox. I use the Chrome brower.

How I get the F4M address? The step is：

For example I chose ‘Meet the Press’ of 6th, Mar., 2016

（1） Open the web page

http://www.nbc.com/meet-the-press/vi...121#vc210121=1

you can find the address from the source page of the above link

https://player.theplatform.com/p/Nnz...deSharing=true

（2） open the above link： https://player.theplatform........, then look for the 'f4m' address in the 'network' tab, as shown in the following figure.

the f4m address is: http://nbcmpx-vh.akamaihd.net/z/vide...hd core=3.5.0

Conclusion: I don't find a suitable plugin for HDS address detection in Chrome. BUT may be this method can be used for a rough search.

Any suggestion?
