Subtitle Access

[jrockow]

I have been searching for quite a while to find the correct attribute to toggle thru the subtitles in my Pyhton VLC script.
When I use VLC directly the "v" works as described.
I can find the "play", "pause", "stop" etc., but nothing to toggle the subtitles.
I apologize if this is not the correct forum to ask for help with this.

That hotkey just flips through the available subtitle tracks.

[jrockow]

Right, that's exactly what I want to do.
Tell me how I can do that with Python.

Shift+v to toggle subtitles.

[jrockow]

You guys are missing the point.
I need to know how to pass the 'v' to VLC via a Python command.

[Rémi Denis-Courmont]

That's in the API documentation.

I've looked at the API documentation. I'm just a low-level coder and that's over my head.
I was just hoping there would be someone familiar with the VLC module that could help me.

Hi, the API changed a bit in 4.0, where this was added:

https://videolan.videolan.me/vlc/group_ ... track.html

In 3.0.x, you could use the following events:

- libvlc_MediaPlayerESAdded
- libvlc_MediaPlayerESDeleted
- libvlc_MediaPlayerESSelected
- libvlc_MediaPlayerESUpdated

(see https://videolan.videolan.me/vlc/group_ ... 2392f62fc6)

As well as those direct functions:

Code: Select all

/** * Get current video subtitle. * * \param p_mi the media player * \return the video subtitle selected, or -1 if none */ LIBVLC_API int libvlc_video_get_spu( libvlc_media_player_t *p_mi ); /** * Get the number of available video subtitles. * * \param p_mi the media player * \return the number of available video subtitles */ LIBVLC_API int libvlc_video_get_spu_count( libvlc_media_player_t *p_mi ); /** * Get the description of available video subtitles. * * \param p_mi the media player * \return list containing description of available video subtitles. * It must be freed with libvlc_track_description_list_release() */ LIBVLC_API libvlc_track_description_t * libvlc_video_get_spu_description( libvlc_media_player_t *p_mi ); /** * Set new video subtitle. * * \param p_mi the media player * \param i_spu video subtitle track to select (i_id from track description) * \return 0 on success, -1 if out of range */ LIBVLC_API int libvlc_video_set_spu( libvlc_media_player_t *p_mi, int i_spu );

(from https://code.videolan.org/videolan/vlc/ ... er.h#L1208)

which you can also find in python there: https://www.olivieraubert.net/vlc/pytho ... index.html

With every ones help and a lot of reading I can finally see my subtitles.
My question now is "can I change the font and/or size of the subtitles"?

Also, how do I exit VLC at the end of the video?

My question now is "can I change the font and/or size of the subtitles"?

Yes, try adding CLI args from python https://wiki.videolan.org/VLC_command-line_help/

[jrockow]

Reading thru the command line help file the closest thing to what I want was "subtitle scaling", at least that's all I can see.
I was hoping for something like a typeface and typesize command.
Let me stress again that I'm a rookie at this, and may have missed your point.
I should also mention that the subtitles I'm working with are imbedded in the .TS file.
