Oh boy! Sorry to be back here again!
Now I am caught again!
They have changed the format of the stream such that my tools fail again.
There appears to be no more any m3u8 stream....
So it is no longer possible to extract by looking for m3u8...
If I hit F12 when I display the webpage https://msnbcdailyshows.com/ I see a lot
of stuff streaming by on the Networking tab and it seems to be instead of m3u8
some <changing_text>.dash, like this:
https://vsd79.mycdn.me/dash/stream_1146644400798/stream.manifest/sig/RcfEI7wlP-c/expires/1636066246262/srcIp/158.174.104.130/clientType/0/srcAg/GECKO/mid/2125507010206/frag-high-6827906.dash
Is it possible to find a working URL for ffmpeg to use in such a situation too?
I have tried to check the site using this command:
youtube-dl -F https://msnbcdailyshows.com/
After some thinking it returns:
[info] Available formats for 2125507010206:
format code extension resolution note
hls-109 mp4 864x488 109k
hls-175 mp4 640x360 175k
hls-485 mp4 428x240 485k
hls-782 mp4 1280x720 782k (best)
So I tried to use youtube-dl to download the video:
youtube-dl -f hls-175 -o test.mp4 https://msnbcdailyshows.com/
And it seems like it is doing what it should as if it was a regular youtube
streaming video, however I cannot stop it successfully like I can with normal
youtube streams by using ctrl-C. And Youtube-dl does not have any argument to
set the duration of the download either as far as I can tell.
On normal streaming videos youtube-dl closes the video download on receiving
Ctrl-C and then exits.
And the interrupted video is fixed so it can be played.
So I am using a this command structure in my at job to download a specific
video:
timeout --signal=2 64m youtube-dl -f hls-175 -o xxx.mp4 some-youtube-stream-url
And this causes youtube-dl to run for 64 minutes from when it was started and
then cleanly close the video and exit.
Not so with this one site, here youtube-dl will just abort the download and the
xxx.part file remains and cannot be viewed.
Is there any possibility to use ffmpeg itself to download from this kind of
stream and if so what would the argument for the stream be?
