Hi,
The problem in short: At some point during playback, render time starts to grow and when it reaches a certain point, MediaPortal drops dozens of frames. After this the playback is fine for a while until the same happens again. This only seems to happen if I run MediaPortal on the secondary display (in my case the TV). I do not see any significant spikes in CPU or GPU usage during the frame drops. The problem does not appear to be frame rate or refresh rate dependent as it occurs with a variety of different material. I have also experimented with the dynamic refresh rate control but it made no difference.
As a reference, I configured MPC-HC to use the same filters and decoders (Haali Media Splitter, ffdshow, AC3Filter, EVR custom presenter). It played back the same files full screen on the secondary display with basically no problems (a couple of frames were dropped at the beginning of playback). This makes me wonder, what exactly is the difference between the EVR implementations of MP and MPC-HC...
The two sample video files I used while taking the logs can be found here:
