Strange QMediaPlayer::setPosition() on Windows when play from URL
I try to play video file from URL.
For that i do like this:
QString fileName = "https://r5---sn-jvhnu5g-gv8l.googlevideo.com/videoplayback?........D4B58C1";
I use youtube MP4 URL (url gotten using youtube-dl util) . Playback starts normally but some issues on WIndows 8 and WIndows 10:
- QMediaPlayer::bufferStatus() is always returns zero
- QMediaPlayer::bufferStatusChanged() is never caled
- after QMediaPlayer::setPosition() much forward NO LONGER player update frames, just nothing displayed. This is with long videos like 1-2 hours. Not possible to seek forward.
Interesting is that under Ubuntu Linux same QT app with gstreamer-ffpeg library - all is fine. I can setPosition() i see how bufferStatus() is changing after seek forward from 0% to 100%.. In Linux setPosition() forward is quite fine.
What to do?
Hi and welcome to devnet,
That might come from the fact that the Windows backend and Linux backend doesn't use the same technologies.
