[QUOTE="mironicus, post: 635337, member: 69593"] [b]AW: MP1 EVR Presenter/dshowhelper community development[/b] Some other stutter problem I detected - this seems to be more codec-related but the modified directshowhelper.dll helps here too and it performs much better than the default dll. If I playback 1080p-H264 movies with DXVA enabled (MPC HC-decoder) that starts with high bitrates I have stutter at the very beginning of the movie and I loose about 10-12 frames. After the short stutter the movie plays fine. If I playback 720p-H264 movies I do not notice any stutter at the beginning because only 1-2 frames are dropped. If you watch TV and switch between H264-channels you have the same little stutter at the beginning of the playback. That seems to be the same behaviour like with those 1080p-H264 movies. However there is a hidden option to eliminate those little stutters during channel change if you enable "[b]Do not use slow motion to sync video to audio on channel change[/b]" using the debugoption within Mediaportal Configuration. So... could this option also be used for normal video playback? ;) If I disable DXVA in the codec Mediaportal does not loose frames at the beginning. [/QUOTE]
