    I have tested more VC-1 movies on my PI 4, and I think that if one cpu core is powerful enough to decode the movie (decoder cpu core utilization < 95%), then the playback is smooth (no frame drop), and if one the decoder core utilization is higher than 95% VC-1 playback stutters, there are frame drops.


    yes the switch to software decoding on PI4 for VC-1 and MPEG-2 uses to much CPU (often ~80%) and as you wrote it stutters if a core is used to high.

    would be good if this load could be distributed to the other cores... is this possible?
