What card are you using? I've just added support to the NV50 textured video adapter upstream, but since you say nv works, I'm guessing you're using an older card than GeForce 8 (nv has *no* Xv support for it on that arch). (In reply to comment #1) [ 1065.025] (--) PCI:*(0:1:0:0) 10de:0402:1458:3452 nVidia Corporation G84 [GeF orce 8600 GT] rev 161, Mem @ 0xfa000000/16777216, 0xd0000000/268435456, 0xf80000 00/33554432, I/O @ 0x0000df00/128, BIOS @ 0x????????/131072 The report of XVideo working with the nv driver is a recollection from previous versions of Fedora on other hardware; I have not tried it on the current card under Fedora 13. I didn't want to deal with the pain of turning off the nouveau driver. I don't know how this goes for nv, but I have dealt with it WRT the proprietary nVidia driver. xorg-x11-drv-nouveau-0.0.16-8.20100423git13c1043.fc13 has been submitted as an update for Fedora 13. http://admin.fedoraproject.org/updates/xorg-x11-drv-nouveau-0.0.16-8.20100423git13c1043.fc13 That update fixes my issue. Thank you. xorg-x11-drv-nouveau-0.0.16-8.20100423git13c1043.fc13 has been pushed to the Fedora 13 testing repository. If problems still persist, please make note of it in this bug report. If you want to test the update, you can install it with su -c 'yum --enablerepo=updates-testing update xorg-x11-drv-nouveau'.

Created attachment 439515 [details] Code for XVideo testing with various encodings Description of problem: I have a video stream from an industrial firewire camera which is encoded in UYVY. With radeon driver, Intel driver, nVidia proprietary driver or nv driver, I could feed this directly into XVideo. However, someone at Fedora chose to make the fledgling xorg-x11-drv-nouveau the default driver on nVidia cards, and while it has XVideo, it does not support UYVY. Version-Release number of selected component (if applicable): 0.0.16-7.20100423git13c1043.fc13.x86_64 How reproducible: 100% Steps to Reproduce: 1. compile testxv_yuv program with -lX11 -lXext -lXv 2. run test program: testxv UYVY 3. it opens window, then immediately crashes and closes window. Actual results: Nothing Expected results: Window showing test pattern Additional info: The driver does support YUY2 encoding. Someone should tell the nouveau developers that all you have to do to convert UYVY stream to YUY2 is swap byte pairs. Really, it's that simple.
