[linux-dvb] No xv under 2.6 :-(

[Gregoire Favre <greg@magma.unil.ch>]

Hello,

under 2.5.73 I hadded xv for my first DVB card, now, there is no more XV
(I am running 2.6.0-test1-ac2 with the dvb-kernel from tonight).

xvinfo tells me:

        bits per pixel: 16
        number of planes: 1
        type: YUV (packed)

Running xawtv with -v 2:

main: xvideo extention [image]...
  image format list for port 53
    0x32595559 (YUY2) packed [ok: 16 bit YUV 4:2:2 (packed, YUYV)]

    0x59565955 (UYVY) packed [ok: 16 bit YUV 4:2:2 (packed, UYVY)]

And selecting fullscreen from within xawtv:

Otherwise, it seems to works pretty good ;-)
