Thanks Miryan,
I may be missing a new setting somewhere, but this build still displays flashing white squares on the bottom few lines of Elizabeth. One nudge down fixes it. All the problem lines are below 1080. Attached is a screenshot taken using ctrl-I (quite heavily jpeg compressed to save space, but at original resolution). In my opinion all lines below 1080 should be cropped before display (optionally if you like, but by default). Last edited by Jong; 22nd May 2008 at 12:48. |

I have a weired problem with my new htpc and 1080p24 mkv playback. So far everything plays fine and smooth. DXVA works and CPU load ist pretty low (5-15%). But sometimes the playback becomes jerky for aprox. 0,5-1 second and i have no idea why. It looks like as some frames were dropped but the statistics says "dropped Frames =0". It happens nearly ervery minute but every time at different positions in the movie. I'd monitored the CPU-load while the playback becomes jerky but it stays under 15%.
I tried the MPC-HC decoder, CoreAVC and Power DVD8 Codec. No difference. I'm using Vista Ultimate 32Bit, latest MPC-HC @ EVR and AC3 Filter. All drivers are up-2-date. It's an fresh installation. No other Software like AV-scanners or similar is installed. My System: - Gigabyte 780g Mainboard - 4050e Processor (2x 2,1Ghz.) - 2x 1GB Ram @ Dual Channel - 250GB Samsung SATA HDD - Sony 40V3000 @ 1080p/24 |

They truncate to the target destination give by the parser. I thought Haali was truncated to 1080... I'll look maybe the best thing will be to truncate in the decoder to prevent such things.

I don't really understand the pin data in MPC-HC (not in it's entirety at least!) but the input to the MPC video decoder shows a resolution of 1920x1080 but the output to VMR9 shows 1920x1088. Quote:

Just to add that with this 1920x1088 problem I am not sure it is possible to get 1:1 pixel mapping, or even a correct aspect ratio, of a 1920x1080 blu-ray sourced video to a 1920x1080 screen.
I guess it may be driver dependent. I have an ATI3850 with Cat 8.4. There are many possible permutations of aspect ratio and pan&scan settings but I have yet to find one that displays the video as intended. If 1920x1088 is displayed with the right aspect ratio in 1920x1080 it should be displayed as 1920*1080/1088 by 1080. This leaves small black borders to the left and right. Not to say there isn't one but I have yet to find a combination of settings that does this. If I select "stretch to fit" the video fills the screen horizontally but still has 1088 lines squeezed into 1080. Clearly the video is distorted. If I select "normal size" something odder happens. The video appears stretched even further horizontally, but still with the same vertical compression. It appears the video is being rendered as 1920*1088/1080 by 1080, with a few pixels cropped from left and right to display as 1920x1080. This seems to be the inverse of the adjustment needed to acheive the right aspect ratio |

Well the image above is as captured from MPC-HC using its internal image capture facility (ctrl-I) and you can see it is 1920x1088. All of it is being displayed.
I do not know how to splice a bit of an mkv file. If you can point me to a tool I will gladly do it. How big can the file be? How much do you need? Video only OK? (before I muxed with audio & subtitles?). |

Here is a link to a short clip with some flashing noise in the last few frames:
http://jong.pwp.blueyonder.co.uk/images/clip-004.mkv Please let me know when you have it so I can take it down. Don't know if this is useful but interestingly the final incomplete clip that I cropped from the mkv could not use the MPC filter for some reason and used the Cyberlink filter instead. There there was no noise at the bottom. This was the pin info: Quote:

I have download you sample. It play with mpc internal decoder, but i haven't the squares at the bottom line. Alt+I create picture 1920x1080 too. I have tried with VRM9 windowed and renderless : same results.
Can you post the pin properties with Cyberlink ?
