Mlb Rtmpdump Problem?

[j_cool]

After hls stream detector detects 6 urls right click on game and select one of m3u8s'

I set my hls stream detector to copy m3u8 link as livestreamer command.

Here you see the result:

You can copy m3u8 url and paste it in new tab's address bar and save "1800_complete.m3u8".

Open it and this is one of lines from "1800_complete.m3u8", maybe streamlink knows how to handle that.

#EXT-X-KEY:METHOD=AES-128,URI="https://mlb-ws-mf.media.mlb.com/pubajaxws/bamrest/MediaService2_0/op-generateKey/v-2.3?contentId=1239053383&kid=20269291",IV=0x948886 D04001BCB7CF97A4FA0218DC46



I looked at this website from time to time and never caught a stream until today, and it was as before sound only, no video.

You can install firefox extension "User Agent Switcher", set user agent to iphone 3.0 and get streamlink command as I did.
It will have iphone 3.0 user agent. See if you get the stream playing, as you know streamlink runs VLC.

I don't know what to do about "Failed to create decryptor" error. Can you help? Thanks!

The yoursportsinhd website is using the m3u8 and ts directly from the mlbtv service servers. Then, the yoursportsinhd video player ignores the key url in the m3u8 because it requires secure retrieval with mlbtv service cookies.

Instead, the yoursportsinhd video player substitutes the key off their own server on-the-fly. See proxying the hls aes keys.

If won't be easy to play in vlc directly because you'd have to do the key substitution yourself instead of having the yoursportsinhd video player do it. You can do the monkeypatch idea with livestreamer, mentioned by mckv in post #6 - or you can download the key from yoursportsinhd and setup a local server on your machine and redirect key requests there so that livestreamer will work with vlc.

MCKV,

There are 2 things here:

How it works fine without monkey-patch, we're not getting it for now ?

May I pass your code to Streamlink team to see if they can make some use of it?
I'm not able to until I learn python.

It works fine without the monkey-patch in the example quoted by mckv because the stream shown in his quote is for the MLB Network Channel, which does not use a secure url for the key. The MLB Network Channel only occasionally shows games and mostly has US baseball reporting and commentary.

The livestreams which exclusively stream games always use a secure url for the key.

@ JonDough,

Can you give me an example of how I can do the monkeypatch idea with livestreamer, mentioned by mckv in post #6, using this game? Thanks again!

Streamlink plugin: yoursportsinhd.py.

Save it to

%APPDATA%\streamlink\plugins\yoursportsinhd.py

on Windows or

~/.config/streamlink/plugins/yoursportsinhd.py

on macOS/Linux

This is great for the specfic site. As a general mater, it would be great if streamlink had a command variable to override/substitute the aes key urls in a hls playlist with data from a local copy of the key(s) or in a config file.

Too often the key retrieval from the hls playlist url requires complex cookie parameters or intermittent access of another url that is not in the playlist. If streamlink had some dynamic options to override the playlist key urls and utilize local copies of the keys, it would be very useful for these cases.

Thanks again for the plugin!

Thank you very much for the help! Is it possible to include "Select Feed" option in yoursportsinhd.py? Thanks again!

By feed, do you mean the quality? If so, that can be selected using the usual hls parameters of streamlink. In this case: 540p, 720, best, etc.
If you mean something else by feed, explain.
