Streamlink & Xfinity (SAMPLE-AES)

[streamtownmall]

Has anyone successfully found a way to use streamlink for downloading an on-demand stream from Xfinity (xfinity.com/stream)? An example m3u8 URL is: https://ccr.ipvod-cim.top.comcast.net/v1/frag/bmff/enc/cbcs/t/cimomg06/OPUS/733/431/15..._500000_5.m3u8

The stream is DRM protected with SAMPLE-AES and I haven't been successful in any methods so far with ffmpeg, youtube-dl, and streamlink. I'm wondering if there's a specific process someone has discovered that works. Thanks in advance!

Here's an example of a download attempt with streamlink:

additionally, here's the output from youtube-dl -F:

Url?

[streamtownmall]

the m3u8 url is linked in my last few posts. Is there a different one you'd like?

edit: just in case, here's the URL where the m3u8 was pulled from: https://www.xfinity.com/stream/entity/7326589994731892112

When you play it in your browser, does the web player actually play those hls (m3u8) sources? Or does it play dash sources (mpd) instead?

[streamtownmall]

I'm not certain. It'll pull down about 110 mp4 segments at a time and play through those. The mp4's are linked in this format:

https://odol-atsec-cca-03.ipvod-cim.top.comcast.net/v1/frag/bmff/enc/cbcs/t/cimomg06/O...0-frag-108.mp4

The page source shows the embed using the m3u8 link:

<video src="https://ccr.ipvod-cim.top.comcast.net/v1/frag/bmff/enc/cbcs/t/cimomg06/OPUS/733/431/1577020995979/1564156608713/1577020995979_1564155138774_500000_5.m3u8" iswrapped="true" style="height: 100%; width: 100%;" c-t-playing="true" c-t-pause="true" ispaused="true"></video>

The page also has reference to "DashMpdConverter" in the PlayerPlatformAPI.js but I don't know if that's an option for other means of streaming.

Xfinity's page source for this stream also shows:

   "asset.streamingFormat": "mpd" === XTV.Player.api.asset.getUrlType() ? "DASH" : "HLS",
                    isEMESupported: XTV.isEMESupported()
