Hi everybody,


I'm working on an addon for the F1TV official streaming service.
I think I got the business logic/parsing of the API right.
Now I started to create a simple addon that lets you browse the entire archive of the streaming service.

However:
The stream itself is provided using an m3u8 file that seems to be unique per user/session.
When I try to open the link to this file using xbmc.Playlist().load(url) it just fails with the error:
bash:
17:59:26.370 T:123145319133184   ERROR: EXCEPTION Thrown (PythonToCppException) : -->Python callback/script returned the following error<--

The M3U8 looks like the following:

Code to open:
python:


playlist = xbmc.PlayList(xbmc.PLAYLIST_VIDEO)

playlist.load(path)

xbmc.Player().play(playlist)

Am I missing something?

Thanks for your help

How could we tell anything without seeing the code?

And I guess even with the code we couldn't help much. There must be a reason you edited the files before providing them.

That's only a personal guess, but if you want us to support any kind of piracy, then this is the wrong forum for you.

Try:
 
python:
xbmc.Player().play(path)

No, this is definitely not about piracy.
I even implemented a layer using their official authorization API.

The reason I edited the file is because in each returned playlist there are user specific tokens, and as I donˋt want to share my credentials/tokens here I needed to edit them...

 You are my hero sir!

Thanks a lot - it works even better than expected.


Now some more code cleanup needs to be done and eventually I can start publishing it at the weekend!

Thanks for working on it, much appreciated.
If you have further questions feel free to ask here. If you need testers (mainly from germany) let me know.

Alright, I will definitely need further support for testing esp. because I would like somebody with TV Access to test (I only have Pro).

I‘ll post an update here once I did some further cleanup!

Okay...
I guess I pretty much made some progress with my addon.
Unfortunately, there are still issues with the playlist:
In some of the m3u files there are variants for each stream:
m3u:


#EXTM3U

layer_1_<<SPECIAL_TOKEN>>/<<FILENAME>>_<<SPECIAL_TOKEN>>_1.m3u8

<<....MORE VARIANTS OF THIS IN DIFFERENT RESOLUTIONS....>>

In the above example you can see:
<<SPECIAL_TOKEN>> == Token that seems to be user/session specific
<<FILENAME>> == The filename of the m3u file, not relevant here. Is always the same

The problem is: When I try to view this with xbmc.Player().play(path), I only get ONE video (line 15) and TWO audio streams (line 6 + 7, group "audio-aacl-130").
Is it possible that the player does not evaluate the complete playlist file?

Xbmc.player is limited to scripts and NOT recommended for plugin use. Use setresolvedurl

xbmc.Player() is used to prevent "watched" marks and resume points from being saved for live content links.

It doesn't work this way... you are using a hack and improperly using the xbmc.player() class which was designed for scripts and not the plugin VFS.
