Hello! I'm trying to write simple application with LibVLC and have a problem. I need to crop video, so I've written the following code (roughly): vout_thread_t *vout = 0; vlc_object_t *main = libvlc_get_vlc_instance(vlcInstance); if (main) { vlc_object_release(main); vout = (vout_thread_t *) vlc_obj...

Further "investigation" had shown, that despite ftp's "unseekable nature", 'Open' function inside modules/demux/avi/avi.c tries to seek it . More precisely, it tries to call AVI_IndexLoad on this stream, which in turn calls AVI_IndexLoad_idx1. This call fails, because reading uns...

UPDATE I've downloaded that file and compared logs with diff, here's some interesting thing (as far as I can guess). Highlighted parts are only present when opening local file... avi debug: </list 'INFO'> avi debug: found Chunk fourcc:4b4e554a (JUNK) size:1122 pos:13206 avi debug: found Chunk fourc...

Hello! I have a problem with AVI playback directly from FTP. The problem is, VLC is trying to seek past over the end of file, and playback fails. One suspicious line in log just before this over-the-end seek: "[VLCLOG] [WRN] demux.avi: seems to have lost position, resync" . Full log is at ...

One detail: there's periodic calls to libvlc_audio_set_track (every ~1min.) in my working (GUI) thread. Removing this calls seemed to remove hangs. So I consider what happens is this: stream playback "hangs", call to libvlc_audio_set_track occurs, effectively blocking input thread (or maki...

Hello! I have the following situation. I play multicast UDP stream with libvlc. Then suddenly playback stops, and when I try to access any of the functions libvlc_media_player_* , they all hang altogether with my GUI. It only occurs on two specific streams, both are HD-quality. The thing is I cannot...

Hi! I need to have a "pause" functionality in my application -- simply freeze frame and stop playing, and after un-pausing stream should continue from the current time point. But VLC seems to make time-shifting instead, which is pretty cool, but not the kind of behaviour I want. I can just...

Actually it's true. I'm playing network stream, so I think audio track info is not available till stream is cached. Making a slight delay fixed situation, thank you.

Hello! I have videos with multiple audio tracks and I want to handle them from my code, which uses libvlc api. I've tried libvlc_audio_get_track_count, libvlc_audio_get_track_description, but the first always returns 0, and the second -- NULL. How can I do just that: enumerate audio tracks in video ...

But aren't video filters working inside this internal video output thread? I'm trying to call pf_display from the event handler inside my video filter.

Hello! I'm writing custom application built on top of VLC. Application in essence is pure VLC with OSD interface on top of it. And though this is OSD interface, it is implemented as a "video filter" module (because I'll need to scale video source at some point, but that's another story). J...
