snip [huffyuv @ 0x8e1890]Error: YV12 is not supported by huffyuv; use vcodec=ffvhuff or format=422p what happens if you follow that instruction?
Oops I totally forgot about posting that. And it seems like I overlooked there were TWO different option. The ffvhuff one does not work. The other one does. Nevertheless I posted both results. As I do not know if it is a bug or not, I will leave it as 'new' instead of 'invalid'. Maybe it has to be that way with versions >= 1.0_pre6 though. ***************************************************************************** $ mencoder -o tvcapture.avi -ovc lavc -lavcopts vcodec=ffvhuff -oac pcm tv:// -tv driver=v4l2:alsa MEncoder 1.0pre6-3.4.3 (C) 2000-2004 MPlayer Team CPU: Advanced Micro Devices (Family: 8, Stepping: 10) Detected cache-line size is 64 bytes Cannot test OS support for SSE, disabling to be safe. 77 audio & 189 video codecs File not found: 'frameno.avi' Failed to open frameno.avi success: format: 9 data: 0x0 - 0x0 TV detected! ;-) Selected driver: v4l2 name: Video 4 Linux 2 input author: Martin Olschewski <olschewski@zpr.uni-koeln.de> comment: first try, more to come ;-) Selected device: Terratec Cinergy 600 TV Tuner cap: STEREO LANG1 LANG2 Tuner rxs: MONO STEREO Capabilites: video capture video overlay VBI capture device tuner read/write streaming supported norms: 0 = PAL; 1 = PAL-BG; 2 = PAL-I; 3 = PAL-DK; 4 = NTSC; 5 = SECAM; 6 = PAL-M; 7 = PAL-Nc; inputs: 0 = Television; 1 = Composite1; 2 = S-Video; 3 = Composite2; Current input: 0 Current format: BGR24 v4l2: current audio mode is : STEREO [V] filefmt:9 fourcc:0x32315659 size:640x480 fps:25.00 ftime:=0.0400 ========================================================================== Opening audio decoder: [pcm] Uncompressed PCM audio decoder AUDIO: 44100 Hz, 2 ch, 16 bit (0x10), ratio: 176400->176400 (1411.2 kbit) Selected audio codec: [pcm] afm:pcm (Uncompressed PCM) ========================================================================== Opening video filter: [expand osd=1] Expand: -1 x -1, -1 ; -1 (-1=autodetect) osd: 1 ========================================================================== Opening video decoder: [raw] RAW Uncompressed Video VDec: vo config request - 640 x 480 (preferred csp: Planar YV12) VDec: using Planar YV12 as output csp (no 0) Movie-Aspect is undefined - no prescaling applied. videocodec: libavcodec (640x480 fourcc=48564646 [FFVH]) [ffvhuff @ 0x8e1890]This codec is under development; files encoded with it may not be decodeable with future versions!!!

Please read the messages from libavc : [ffvhuff @ 0x8e1890]This codec is under development; files encoded with it may not be decodeable with future versions!!! Set vstrict=-1 to use it anyway. Bug marked as invalid. Please relax a bit and remember that is better keep a cool mind and read what is wrong before taking any action. I hope it is working as supposed afterall
