[SOLVED] VLC: gnutls tls session error when playing remote file

VLC: gnutls tls session error when playing remote file

I'm using the python-vlc library to play audio.

import vlc
import time

player = vlc.MediaPlayer('https://r1---sn-cu-nuoe.googlevideo.com/videoplayback?ip=5.81.184.196&sparams=clen%2Cdur%2Cei%2Cgir%2Cid%2Cinitcwndbps%2Cip%2Cipbits%2Citag%2Ckeepalive%2Clmt%2Cmime%2Cmm%2Cmn%2Cms%2Cmv%2Cpl%2Crequiressl%2Csource%2Cexpire&gir=yes&id=o-AHt-uyg7B2wvOuqq_PMrTGhjp-zwBd_fKvwvxFrryBFF&expire=1508865966&keepalive=yes&initcwndbps=913750&ipbits=0&mime=audio%2Fwebm&dur=205.008&lmt=1500954362115026&key=yt6&itag=171&source=youtube&requiressl=yes&clen=3247546&mm=31&mn=sn-cu-nuoe&ei=TiPvWYqfBtaBVI2ZurAI&ms=au&mt=1508844287&pl=25&mv=m&signature=C509ED606089E3A98A4740C2AD355F663A8DC0C8.86347E6F134BC6953927084455DC74A7371F0893&ratebypass=yes')
player.audio_set_volume(20)
player.play()
time.sleep(100)

I get the url from youtube-dl like this:

youtube-dl -g -f "bestaudio" <video-id>

It works fine initially however at a seemingly random point and not with every file this error message appears:

[02f8a9a4] gnutls tls session error: Error in the pull function.
[02fdba24] core access error: read error: No error

I've run it again with GNUTLS_DEBUG_LEVEL=99 and got this (last few lines included here)

VLC version: 2.2.6

Edit: I've reproduced the same error in proper VLC. The errors at the point of failure are the same, here is the full log.

Solution

Looks like this was a bug in VLC 2.2.6

Trying the nightlies (specifically 3.0.0) I've not yet had any problems so I think it's been fixed.
