I'm trying to use gstreamer to decode 4K video with subtitles.
It work fine with Full HD video (1080p) with the command :
gst-launch-1.0 playbin uri=file:///home/root/Sintel.2010.1080p.mkv
But when I use it on a Ultra HD video (4K), the CPU become overloaded, and the video fail.
I suppose gstreamer try to add subtitle into video without hardware acceleration.
Are those type of issue encountered on I.MX6 ?
Does the gstreamer subtitle with hardware acceleration exists ?
