Sorry for reviving an old thread - but i’ve been playing with the GLvideo today and find that it’s a little shuddery as if it’s missing frames. I have the PI’s graphics set to 1080 @50fps, which is my local standard in the UK. I’ve tried the 480, 720 and 1080 MOV and AVI files from Blender (big buck bunny) and find the 720 and 1080 to be jumpy. Playing back from a class 10 SD card, nothing else running. Any idea’s where to look to trouble shoot this? AFAIK the Pi 3B should be able to process x264 video without any issues at fullHD. (audio is working just fine)
