To overcome this issue which part of the script that I need to modify. It was mentioned that the change_prefix.sh is re-written. Could you make this modified script available "I also found that change_prefix.sh, which rewrites .pc files to deal with their chosen location, used the -i option whi...

I want to know where in the source the underlying functionality is implemented for libvlc_media_player_next_frame. Basically what happens when var_TriggerCallback( p_input_thread, "frame-next" ); called. Where is it implemented ? void libvlc_media_player_next_frame( libvlc_media_player_t *...

Hi, If I open a multi-track video file say that consists of 3 video streams, it will pop up three video windows. Their titles (video window titles) just says "VLC" (2nd and 3rd stream). Instead of this, is it possible to add track names to the title ? Or a similar approach that uniquely id...

In my libvlc qt based player i need to always use an one instance, i.e. when a media file is double clicked while another file is running, the double clicked file should open in the same instance that currently running. It may close the existing file and start to play the new file. But, when I doubl...

You are too vague.

OK think I found it. src/video_output/video_output.c

vout_PutSubpicture( vout_thread_t *vout, subpicture_t *subpic )

Hi, When .mkv files are played with a subtitle track, which vlc source files handle the subpicture display for subtitles at the video output level. Requirement is to manipulate the part so subtitles does not appear at the video out put level while they appear at the decoder level. In a linux environ...

I want to implement disable / enable subtitles in the custom player I developed. In VLC when we do this it removes the corresponding decoding module and reload it when enabled. For example, if we want to disable 'subt' type subtitles, when the disable subtitles option is selected it will remove usin...

Hi, I have a custom player developed using libvlc. I want to play a file within the player when the file is double clicked. For the specific file type I have selected the mimeopen option to be the player I developed. So when I double click the file it opens the corresponding player, but it does not ...

How does libvlc_media_player_next_frame() behaves on a multi video track file like .mkv. If the .mkv file is consisted of 3 video tracks and after they are opened in 3 simultaneous windows (vlc opens them and plays simultaneously), when libvlc_media_player_next_frame() is executed it only affects on...

Does it work with the hotkeys?

Hi,

Currently vlc has the ability to adjust delays between subtitle/ video and audio/ video and hotkeys do work for these. My requirement is to adjust the delay between two video tracks (i.e. video/ video) in a multi video file. Not sure how ro do this at the moment.

No, this is only for streaming.

Hi,

Is there a way to do this, that is to introduce an arbitrary delay to a specific video track of a multi-track .mkv video file. By modifying mkv.cpp or etc.

Can I use the options sout-delay-id and sout-delay-delay to delay a specific video track of a multi track video file. ex:- .mkv file with three video streams.

I have a mkv file with multiple video streams and when the file is opened in vlc the streams are played simultaneously in separate windows, but they are out of sync. How to correct this ?

Hi, My video files contain 'subt' type subtitles and it's being decoded by modules/codec/subsdec.c. I can see the subtitles without a problem when the video is played. Also, I can see subtitles are being properly decoded while the video is played as I print the value of “p_spu_sys->text” of the func...

Then you need to get access to freetype or do a similar plugin than freetype. Hi, subsdec.c is indeed the file that is being used as the subtitle type is 'subt'. I modified the "static subpicture_t *ParseText( decoder_t *p_dec, block_t *p_block )" function in this file to dump the subtitl...

What do you want to extract? The text? Hi, Yes indeed, the text. We are just passing simple text along with the video. As an example following type of text will appear along with the video in the subtitle form, i.e., whether or not a horn is being pressed and so on. Horn 0 Break 1 Bell 0 So I need ...

Hi, I have a .mkv video file with soft subtitles. I can extract subtitles from this file into a separate file using mkvextract successfully. But, my requirement is to access and manipulate the subtitles while the video is being played by the custom Qt + libvlc player I developed. Is there a way to i...

Hi Agron, Thanks for the reply. So I need to pass this when I create a libvlc instance as an argument, right? libvlc_instance_t* libvlc_new(int argc, const char *const * argv) I did not check that. As a result I permanently enabled it and recompiled vlc, so RTP over RTSP (TCP) will be selected by de...

Hi,

How to set above option via libvlc. Is there a function to do it ? I want to change 'Input and Codec Settings > Live555 Stream Transport Option' from HTTP(default) to RTP over RTSP.

In vlc this option is found under Tools > Prefernces > Input and Codecs

Hi Rémi,

If I were to modify a section of vlc to direct the opened windows to a single window ( as it capable of playing the embeded video on three windows without a problem) what source files I should focus on? As I started developping using libvlc nearly a week ago

When a .mkv file with three video tracks is opened via libvlc functions it pop-ups three separated windows in a disordered manner. I want to open these three windows in a single window through libvlc. How can I do this? My custom application is based on Qt and libvlc and it is capable of running sin...
