Hi, I want to use libvlc_video_set_crop_geometry in vlc-.1.0.3 to crop video to get something like vlc player does, when choosing Video > Crop > 16:9. I am calling libvlc_video_set_crop_geometry with parameter 180 x 120 + 0 + 0 but nothing happens. I tried other numbers but still nothing happens. Wh...

Hi, we are using vlc-1.1.0, which is 2 weeks old. I want to display some text on the screen with marquee. I cannot do anything until I init marquee with libvlc_video_set_marquee_int(_asd, libvlc_marquee_Enable, 1, &_vlcexception);. But then the text "VLC" is displayed on the screen and...

Hi,

We want to use libvlc 1.1.0 version in our application. So I wonder, if there is any known stable git commit or branch of 1.1.0 version. Or should we just clone the trunk?

Thanks,
Juraj

I recompiled the newer version from git (from yesterday) and there is no problem with volume. So I think it was already fixed. Sorry for bothering.

Hi, I use libvlc 1.1.0 (from git 11.01.2010) under mac 10.6.2 and always when I want to do something with volume (functions libvlc_audio_get_volume, libvlc_audio_set_volume or libvlc_audio_set_mute) I get following libvlc fatal error: LibVLC fatal error locking mutex (22) in thread 140735082355680 a...

@Remi: Yes, I think I built everything correctly. 374 plugins are loaded at run-time, no "cannot load plugin" warning at run-time. I will further investigate this problem, I just wanted to know if there is not some change in functions between versions like libvlc_media_player_set_xwindow (...

Hi guys, We want to switch from vlc-1.0.3 to vlc-1.1.0. I compiled sources of vlc-1.1.0 from git on Ubuntu 9.04 and want to use it in our application, which used vlc-1.0.3 so far. I embed video output in Qt widget this way: libvlc_media_player_set_xwindow(_mediaplayer, _displayWidget->winId(), &...

Yes, I understand that. But then when I removed old libvlc and libvlccore from /usr/lib and recompiled vlc-1.1.0 again, some plugins were built without reference to libvlccore and these plugins didn't work properly (e.g. audio_filter/liba52tofloat32_plugin.so). But I resolved this problem already. I...

Hi, I compiled VLCKit (also with all vlc libs) successfully from git on January 11. However I got some errors at the beginning, see this: viewtopic.php?f=12&t=70368

I removed libvlccore.so.2 from my /usr/lib and recompiled everything. My app starts now without crash but several of vlc plugins are not loaded. I checked ldd for new vlc-1.1.0 plugins (not working) and old vlc-1.0.3 plugins (working) and: new vlc-1.1.0 plugins (not working): ldd audio_filter/liba52...

Thank you. I pulled the git source code and compiled it under linux. However I am getting an error, when starting my app and initializing libvlc with options "-I", "dummy", "--ignore-config", "--verbose=2", "--no-plugins-cache": [0x88cd210] main libv...

Is it possible to use marquee funtions in libvlc (http://www.fr.videolan.org/developers/vlc/doc/doxygen/html/group__libvlc__video.html#g72b965e7dc02755132302312a7b20943)? When I tried to use it libvlc_video_set_marquee_option_as_int(_mediaplyer, 2, 10, &_vlcexception); I got an error: error: ‘li...

Hi,

I pulled the newest version from git yesterday (VLC media player - version 1.1.0-git The Luggage ...), compiled and there is no function libvlc_exception_get_message (in src/control/core.c). Was the function considered to be obsolete? How can I get human readable error message?

Thanks.
Juraj.

Better, but I am still getting errors. I did following: 1.) opened vlc-config.in 2.) changed vcdx section: libs="${libs} -liconv -lvcdinfo -liso9660 -lcdio" 3.) rerun make and got errors: Undefined symbols: "_DASessionUnscheduleFromRunLoop", referenced from: __eject_media_osx in ...

Thanks for your quick replay but I don't know what file do I need to change and what should I write in there. If you have patience yet, please tell me.

Thanks!

Same problem here. I don't understand this sentence "If I manually run the compile line with the -lvcdinfo -lcdio". What is compile line? I tried to do the following, when make didn't succeed. I ran: ./compile -lvcdinfo -lcdio same error. Then I ran: ./compile -liso9660 -lcdio same error. ...

Can this help you - viewtopic.php?f=32&t=69037? I changed and recompiled libdirect3d_plugin.dll. This plugin is responsible for handling key and mouse events in windows.

Mouse and key events for windows are handled in libdirect3d_plugin.dll. To implement vout-event=3 (disable handling mouse and key events in vlc) also for windows I changed modules\video_output\msw\events.c this way: void* EventThread( vlc_object_t *p_this ) { .... // New stuff ... /* key and mouse e...

Hi, is there any way how to display an image (or text on the fly) in vlc output. I would like to display a semitransparent image in video just like vlc does it with snapshot preview when snapshot is taken. Should I create a couple of new functions for that in libvlc or is already something there? Ca...

Hi, I am not 100% sure, but in my opinion NO. When you download vlc source code, you find in src/video_output/vout_intf.c function VoutOsdSnapshot: /** * This function will display the name and a PIP of the provided snapshot */ static void VoutOsdSnapshot( vout_thread_t *p_vout, picture_t *p_pic, co...

I took a look and found 2 problems: 1. I need to keep the aspect ratio of video, not to hardcode the width and height. I doubt, it is possible with vmem (http://forum.videolan.org/viewtopic.php?f=2&t=51447&p=166848&hilit=vmem#p166848). Moreover video window can be scaled in my app even g...

Wow. Your code looks very good at the first glance. I managed to display Qt widget over VLC video on my own - just normal qt approach to overlay 2 widgets (specifying parent without layout). But I cannot make the upper widget semitransparent to see the video thru it on WinXP. I used windowOpacity an...

One more question: is it possible to prevent vlc from responding to double click event. If I want to build a custom video widget which handles fullscreen on its own I need to prevent vlc to respond to double-click. I know there is a startup argument "--vout-event=3", but this is not workin...

Hi,

is it possible to play a video using libvlc backwards (in reverse order)? I want to build a feature, where user can click a back button (in the middle of the movie) and the video start to play backwards. Is it possible to achieve with libvlc and when yes, how?

Thank you very much!
Juraj

Thanks for reply. Can you please tell me, how I can configure vlc to render a static image? I can make a snapshot before the end and then I can tell VLC to display it at the end. Is this a way how vlc do it on double click event? Because as I said, vlc player can go to fullscreen with double click w...
