Use can change the video player zoom using the next keys:
* +: Zoom in
* -: Zoom out
* Up/Down/Right/Left: Move the frame
* r: reset the zoom
Also mouse navigation events can be used for a better UX.
Furthermore, it works with an pipeline using other video compositor
filters like glvideomixer. For instance:
glvideomixer \
name=mix background=1 \
sink_0::xpos=0 sink_0::ypos=0 sink_0::zorder=0 \
sink_0::width={WIDTH} sink_0::height={HEIGHT} \
! glimagesinkelement \
gltestsrc pattern=mandelbrot name=src \
! video/x-raw(memory:GLMemory),framerate=30/1,width={WIDTH},height={HEIGHT},pixel-aspect-ratio=1/1 \
! queue \
! mix.sink_0
Probe was added in the sink pad to get direct navigation events w/o
transformation done by the mixer. More info about it in the PR [1].
