I have 100 LED (32 horizontally and 18 vertically), which have a gap of 2cm compared to the screen (7% and 3% gap).  \r\n\r\nThe problem I have is the following:\r\n=> horizontally the LED are in sync with the displayed picture, if I move a red box over the screen it follows the position correctly and the size of the box is correct\r\n=> vertically, the upper corner of the box is displayed correctly but the lower part is 3 LED too low\r\n\r\nExample: the box has a hight of 4LED  and a width of 4 LED\r\n=> width is correct and 4 horizontal LED show the color of the box, if I move the box, LED follow\r\n=> hight is not correct, the upper start position of the LED is correct but 6 LED are LID instead of 4\r\n\r\nI try now to change this behavior by changing the settings, but can not work it out, what to change. The main issue is in consequence that the lower row of horizontal LED take the color of 70% of the screen and not from the bottom. In other words, the vertical ratio of the picture seems to be wrong and a 4LED high box light 6 LED and a 6 LED high BOX, lights up 8 LED on the side.\r\n"},"comment":{"url":"https://api.github.com/repos/tvdzwan/hyperion/issues/comments/137993462","html_url":"https://github.com/tvdzwan/hyperion/issues/266#issuecomment-137993462","issue_url":"https://api.github.com/repos/tvdzwan/hyperion/issues/266","id":137993462,"user":{"login":"lobocobra","id":7016785,"avatar_url":"https://avatars.githubusercontent.com/u/7016785?v=3","gravatar_id":"","url":"https://api.github.com/users/lobocobra","html_url":"https://github.com/lobocobra","followers_url":"https://api.github.com/users/lobocobra/followers","following_url":"https://api.github.com/users/lobocobra/following{/other_user}","gists_url":"https://api.github.com/users/lobocobra/gists{/gist_id}","starred_url":"https://api.github.com/users/lobocobra/starred{/owner}{/repo}","subscriptions_url":"https://api.github.com/users/lobocobra/subscriptions","organizations_url":"https://api.github.com/users/lobocobra/orgs","repos_url":"https://api.github.com/users/lobocobra/repos","events_url":"https://api.github.com/users/lobocobra/events{/privacy}","received_events_url":"https://api.github.com/users/lobocobra/received_events","type":"User","site_admin":false},"created_at":"2015-09-05T20:37:51Z","updated_at":"2015-09-05T20:37:51Z","body":"I found a fix which works now pretty much for me. Here how I did it...\r\n1) I checked with mplayer, if I have the same issue. So I started mplayer: /usr/bin/mplayer -tv driver=v4l2:width=96:height=54:device=/dev/video0 -vo fbdev -fs -fps 24 -aspect 16:9 -nosound tv:// </dev/null >/dev/null 2>&1 &\r\n=> exactly same behavior\r\n2) I went back to hyperion as it is anyhow faster:/usr/bin/hyperion-v4l2 --frame-decimator 1 --size-decimator 6 --crop-height 5 --crop-width 5 --skip-reply --signal-threshold 0.11 >/dev/null 2>&1 &\r\n3) now I had the idea it might have to do with the ratio and I changed in the json file:\r\n  => picture 96/54 !!! please notice that player is 4:3 and jonson is 16:9. this improved it and now the picture is vertially only  1 LED misplaced, which is acceptable vs the 4 prior\r\n4) in addition I removed the correction factor  of vertical and horizontal gap in jonson config file and did a new config file and changed vertical and horizontal depth to 3%\r\n=> I did not test, what did the change, but now it works... hopefully it helps somebody.\r\n"}}
