I'm trying to play a HLS stream and it works only for 5 minutes. After looking for http packets I did realize that the player isn't changing a cookie that is set on every response.
Look for vssession cookie. After 5 minutes every .m3u8 and .ts file returns error 403

Code:
GET /dvr/m/off24ha/master-playlist.m3u8?h=0411440465697761939438414404691735864119652h6rN-AOOhXZcPlp2UCV8Fg&k=html5&a=F&u=52dfc02cdd23810590000f57_605fd6ba-6320-4a5a-b10f-065e5363421d HTTP/1.1

The addon just play the video by:
Code:
player = xbmc.Player()
        player.play(stream['url'], item)

Any ideas what might be wrong? Is that a Kodi bug?

This looks like a FFMpeg issue, so I did open a ticket on FFMpeg.
https://trac.ffmpeg.org/ticket/4808

If someone code in C/C++, please send a PR to this issue. Looks like an easy fix.

Can you explain how you fixed it? Did you urlencode the '|' chars in the cookie?

The issue was with FFmpeg. I've sent a patch to FFmpeg (https://github.com/FFmpeg/FFmpeg/commit/...316296a78e).
The HLS module wasn't able to handle setcookies during stream, with my patch now every response with setcookie ajusts the cookies of future requests.

But of course I had to force the cookies.
Code:
session = requests.Session()
req = session.get(url)
m3u8_header = { 'Cookie': '; '.join(['%s=%s' % (key, value) for (key, value) in req.cookies.items()]) }
urlvideo = urlvideo + '|' + urllib.urlencode(m3u8_header)

This is interesting. I've experienced a similar situation where I need to clear/set a session cookie on each response. Thanks.

For some reason the kodi isn't using the same path as a pure ffmpeg command line. I'm now unable to debug it.
