Generate Thumbnails

Postby neosettler » 06 Apr 2019 18:02

Greetings,

Giving a try at fetching and/or generating video thumbnails using LibVLC 3.0. Is there a common way to do this? The idea is to populate a custom file browser (using Qt) that display video files with thumbnails.

thank you,

You should look at the thumbnailer from the vlc-android project https://code.videolan.org/videolan/vlc- ... mbnailer.c

Thank you for your suggestion Jean-Baptiste,

I should have mentioned that I'm on Windows but I'll see what I can do with the VLC-Android. It seems like replacing pthread would get the job done.

Having execution speed in mind, is there any recommandation like how to turn audio tracks off? Also, set play does seems like a major over head while only one frame is needed. Basically, even if the process stops after fetching the first frame, the audio has been started.

Seriously, read the android libvlc thumbnailer, it is very easy to adapt.
