Hi Franco,

It's good to hear that I'm not the only one using wxMediaCtrl :)

Although it has a steep learning curve, I do seem to get around all my
problems eventually. And I now have a nice display of wxMediaCtrl and I
even have some editing going on.

With regard to your problem:

1) Firstly, do you have control over the server end? Maybe you could
experiment with using a different codec?

2) Secondly Windows is generally very tolerant of poor encoding, but VLC is
better. There is a VLC backend out there somewhere:

http://www.nabble.com/Introduction-%2B-patches-for-wxGrid-%2B-proposal-for-v
lcbackend-td20090167.html

But it's not part of wxWidgets yet (apparently).

I think it would be very a nice addition.

Try using VLC standalone and see if it works.

Good luck.

Regards

Steve

as expected.

After trying also to update, the issue remain the same.
But i've found something new.

After many try, i found that if i try to open the stream using mplayer (
with subprocess.Popen ), if i set the -nocache option in the mplayer command
line, i don't get any sound and i see in stdout "stream not seekable", if i
put a -cache 32, all work great.

The same using directly WMP, if i let the player doing some caching, it
work, if i set cache to 0 it won't work.

So, maybe can be just a caching issue, on gstreamer it work, but on
quicktime and wmp if i don't let the player doing some minimal caching, the
stream won't work, and wx.media.mediactrl seem to launch the player without
any caching.

Is there any way to set a minimal cache on both wmp and quicktime?
