<div>Hi Pierre,</div>
<div> </div>
<div>Have you had a chance to look at this (see description below)? I can download and try the latest build, but wanted to know if anything changed before trying it out. Of course I never rule out that there isn't any problem and that I am just doing things wrong. In that eventuality, let me know if you have any idea on how differently I should do things, I would greatly appreciate. It is a bit problematic for me to not be able to start a new play from inside the media reached end callback.</div>
<div> </div>
<div>Thanks for your help,</div>
<div> </div>

<div>Hi Pierre,</div>
<div> </div>
<div>Unfortunatly my plan didn't work as well as I had hoped. Here is in a nutshell what I do in the callback now:</div>
<div class="Ih2E3d">
<div> </div><font size="2">
<div>I create a new media descriptor (libvlc_media_descriptor_new)</div>
<div>I add options (<font size="2">libvlc_media_descriptor_add_option)</font></div>
<div></div></font></div>I set the descriptor (<font size="2">libvlc_media_instance_set_media_descriptor)</font>
<div class="Ih2E3d"><br>
<div><font size="2">I start the play (<font size="2">libvlc_media_instance_play)</font></font></div>
<div> </div></div>
<div>The rest I do once at start up:</div>
<div class="Ih2E3d">
<div> </div>
<div>
<div>I create a media instance (<font size="2">libvlc_media_instance_new_from_media_descriptor)</font></div></div></div>
<div>
<div>I get the event manager (<font size="2">libvlc_media_instance_event_manager)</font></div>
<div class="Ih2E3d">
<div>I attach to it (<font size="2">libvlc_event_attach)</font></div></div></div>
<div> </div>
<div>Now when I am in the event it hangs in the call to libvlc_media_instance_set_media_descriptor. This happens independently if I call from the event or if I post myself a message and do it there! Strange! In an attempt to figure things out I have added a call to <font size="2">libvlc_media_instance_stop prior to calling <font size="2">libvlc_media_instance_set_media_descriptor. This makes things work IF not called directly from the event, otherwise it hangs in libvlc_media_instance_stop. </font></font><br>
</div>
<div>Hopefully I have included enough details to help you out.</div>

<div>Hi Pierre,</div>
<div> </div>
<div>I just took a closer look at the API and I will try creating a media instance that will be used for the life of my application and use libvlc_media_instance_set_media_descriptor for each new file I play. That way I won't release the media instance from inside my event. This seems like a much better idea. I'll let you know how it turns out. </div>

<div>Hi Pierre,</div>
<div> </div>
<div>Well yes the problem is with the release of the media instance and it probably make sense that it hangs there. But I don't know how to do things diffrently. If I need to create a new media descriptor and then get a new media instance from it, if I don't release the previous one won't I end up with memory leaks? Here is what I do in my event callback. Any suggestions on what to do differently for things to work? </div>
<div> </div>
<div>I detach from the event manager (libvlc_event_detach)</div>
<div>I release the media instance (libvlc_media_instance_release)</div>
<div>--> and it hangs right here as expected <---</div>
<div>I create a new media descriptor (libvlc_media_descriptor_new)</div>
<div>I add options (<font size="2">libvlc_media_descriptor_add_option)</font></div>
<div>I create a media instance (<font size="2">libvlc_media_instance_new_from_media_descriptor)</font></div>
<div>I release the media descriptor (<font size="2">libvlc_media_descriptor_release)</font></div>
<div>I get the new event manager (<font size="2">libvlc_media_instance_event_manager)</font></div>
<div>I attach to it (<font size="2">libvlc_event_attach)</font></div>
<div><font size="2">I start the play (<font size="2">libvlc_media_instance_play)</font></font></div>
<div> </div>
<div>I hope this helps you figure things out. Let me know if you need more details.</div>
<div> </div>
<div>As always: thanks for your help it is greatly appreciated!</div>

I may not be doing things correctly but presently it simply hangs in my callback. Probably because I am trying to release something that is probably what is calling me back! :-) The media descriptor. I have circumvented the problem by posting myself a message (I am working under Windowzzzz) and this lets me do what I want since in the handler for this message I am out of the libvlc_MediaInstanceReachedEnd event callback. But I would rather not have to resort to this double callback scheme to get things working. </font><br>

<div>This is a bit weird cause you shouldn't get issue when releasing the media descriptor in the media_instance callback, unless you are releasing the media instance that currently plays the media descriptor.</div>

<div>Tell me if you encounters more trouble, I'll have a look over the weekend.</div><font color="#888888">
