stopping a dash stream on last 2.1.0 nightly build

[angelo.difino]

Dear vlc and dash team,
I'm currently using the last nightly from vlc to stream video with dash, but in the
last WIN32/64 versions of the 2.1.0 nightly (from vlc-2.1.0-git-20120806-0005 and
beyond, towards vlc-2.1.0-git-20121003-0003) I'm encountering some problems
when i "stop" the player. Since the problem seems kind of random, I've some
difficulties to open a issue on this subject.
The problem seems not reached in simple HTTP scenarios.

The main problem encountered is (when i stop the rendering):

Code: Select all

[026a8318] main stream error: Polling error: Non-socket handle specified

The detailed stack trace is:

I confirm it happens also on a MacBoookPro (MACOS 10.7 Intel i7 x64)
with last nightly build.

the complete stack trace now is:

Does VLC hang after that?

[Rémi Denis-Courmont]

I don't see any stack trace. It seems like a bug in the DASH plugin cleanup.

[angelo.difino]

Yes, the vlc hang after i've invoked the STOP... even on Macos.

I attach the complete stack trace made today with last nighly
vlc-2.1.0-git-20121004-0003-win32

the trace is very verbose since it tooks me 6/7 attempts before failing :/

--> http://research.cedeo.net/angelo/mylog.txt

[angelo.difino]

i've noticed also some strange behaviors when EOF is reached.

i'll take a look to the source code this weekend and next days... i'm already in contact with dash
developers but if someone is looking this issue or has some knowledge to share, contact me privately!
