Aaaah, it’s UTF-8. That’s mostly what I already tried except I didn’t tried the correct charset. Awesome. Thank you! I totally agree with you it is unnecessary to build a huge framework around libvlc. The one I used before was so complex I didn’t know where to start looking for an error that occured somewhen… now it’s easy and transparent.

Hi Konzertheld, please take a look at this thread and see if it works:
http://forum.videolan.org/viewtopic.php?f=32&t=53714

The method converts the UTF-16 string to a UTF-8 byte array with System.Text.Encoding.UTF8.GetBytes and passes it as a byte array instead of a string to the libvlc function.

Another alternative may be to set the charset of the string to UTF8 when importing the function from the dll, but I have not tested this.

Thanks, that helped a lot, understanding and using. The only trouble that remains is when I have German umlauts in my file path. It is a VLC issue, do you have any idea how to work around that? I tried URL encoding, did not help. I also tried passing an ISO-8859-1 byte array instead of a string to libvlc_media_new_location or (libvlc_media_new_file, what I’m usually using), also did not help. When I pass such a file, just nothing happens, it seems to be played and no error occurs but it is not played. When I rename the file so there are no more umlauts it works fine. Would be great if you could help me with that…

George,

Thanks a big heap for the simple article. I was able to use the examples to get my unattended remote play out server working with one exception. If I play a file for a certain duration say 30 minute, but it turns out to end after 15 minutes, the player still says it is playing and freezes on the last frame and will stay there until my timer says it should be done. I thought I could check for being stopped or set a stopped event, but that doesn’t work. I tried the command line parameter –play-and-exit, without success either. I didn’t see any functions on the VLC page you referenced in the previous post (or maybe I didn’t know what to look for). Any advice?

Thanks.

Try libvlc_media_player_set_rate. If you're unsure how to use the function, read both pages of this post. That's what the purpose of it is, and you can apply it to any function..
