Description of problem: The patch openchrome-0.2.904-I420_Xv_surface_for_CME.patch attempts to add I420 support to Openchrome. It is incomplete, viaQueryImageAttributes is lacking a case statement to correctly calculate the pitches and offsets for I420. Hence it calculates the pitches/offsets in the default: section which assumes a single plane. A single pitch/offset is returned to vlc, which then cores when trying to use the 2nd and 3rd pitches which should be there. How reproducible: 100% Steps to Reproduce: 1.Play mpeg2 video in vlc 1.1.4 on fedora 14 2.Core Actual results: Expected results: Additional info: Adding case FOURCC_I420: above case FOURCC_YV12: in viaQueryImageAttributes allows I420 playback with incorrect colour - as U and V planes are obviously reversed. This shows that I420 should be treated as a 3 planar mode similar to YV12 - they are the same except U and V are reversed. THis also shows that the rest of the code for I420 support is correctly working, it just needs to correctly determine pitch and offset.

This message is a notice that Fedora 14 is now at end of life. Fedora has stopped maintaining and issuing updates for Fedora 14. It is Fedora's policy to close all bug reports from releases that are no longer maintained. At this time, all open bugs with a Fedora 'version' of '14' have been closed as WONTFIX. (Please note: Our normal process is to give advanced warning of this occurring, but we forgot to do that. A thousand apologies.) Package Maintainer: If you wish for this bug to remain open because you plan to fix it in a currently maintained version, feel free to reopen this bug and simply change the 'version' to a later Fedora version. Bug Reporter: Thank you for reporting this issue and we are sorry that we were unable to fix it before Fedora 14 reached end of life. If you would still like to see this bug fixed and are able to reproduce it against a later version of Fedora, you are encouraged to click on "Clone This Bug" (top right of this page) and open it against that version of Fedora. Although we aim to fix as many bugs as possible during every release's lifetime, sometimes those efforts are overtaken by events. Often a more recent Fedora release includes newer upstream software that fixes bugs or makes them obsolete. The process we are following is described here: http://fedoraproject.org/wiki/BugZappers/HouseKeeping
