Decoding video stalls on movie end or frame seek #703

Open GoogleCodeExporter opened 9 years ago

GoogleCodeExporter commented 9 years ago 
Have you tried Pyglet 1.2 alpha1 or the repository code?
YES.

I tried following combinations:
Windows 8 64 bit with Python 32 bit:
2.6.6 + pyglet 1.1.4 -> bug does NOT occur
2.7.5 + pyglet 1.1.4 and "tip" as seen on 19.02.2014 -> bug OCCURS

What steps will reproduce the problem?
1. I run "media_player.py" from "examples" directory and use an example AVI 
file, without sound,
2. when I play the movie and the movie ends, the whole application window 
stalls (goes unresponsive); if I press CTRL+C at this moment, I get EXCEPTION 
#1 (see below)
3. when I play the movie and I try to seek to a video frame, the app gets 
unresponsive again and if I press CTRL+C at this moment, I get EXCEPTION #2

Paste in the traceback or error message:

AVBin version 5? That's too old I'm afraid/

Can you try to reproduce the bug with a more recent AVBin version? Latest one 
is 10: http://avbin.github.io/AVbin/Download.html

I'm not saying that the bug is not pyglet related, but we can't support an 
AVBin version that is not supported.

Thanks for your report!

Thank you very much for your suggestion! I agree, AVbin 5 is tad old. 

So... 
I just got: fresh pyglet checkout, AVbin 10, python 2.7.6 32-bit
and I was able to reproduce the bug.

As I want to make the bugfixing experience really pleasant for you and as a 
proof of my pyglet-bugfixing journey, I also recorded an interesting 
screencast, that shows the problem. It is available on VIMEO here: 
https://vimeo.com/87213276 (the password is: pyglet). When I submitted this 
comment, website said, that I need to wait about 43 minutes for conversion of 
the video. YouTube would be faster, perhaps. Note to Google: Dear Google, I 
love YouTube and I would use it but you are not going to force me into Google 
Plus, as I value my privacy. 

As I wrote before, my commit I referenced above may be a possible fix for the 
lockup-when-movie-ends issue. I have no business in fixing video seek issue, 
but if you give me some hints, I am sure I'll be able to provide a patch. 

THANKS!

Thanks for the follow up!

I'll try to watch the video when it's ready.
