I'm having problems with image quality with ivtvfb kernel module. The image looks "grainy" with both X server and recorded video that I try to play on the S-video tv-out of my PVR-350 card. The entire screen has a uniform graininess that, if I look closely, looks like it is moving from bottom to top. I'm using kernel 2.6.26-ARCH i686.
I appreciate any suggestions about what it might be or how I could troubleshoot further. Thanks, Dirk Here's what I get when I modprobe ivtvfb: -------------------------------------------------------------------------------------------------------------------------------------------- Mar 8 20:33:34 obmyth ivtvfb0: Framebuffer at 0xe1510000, mapped to 0xf9a10000, size 1665k Mar 8 20:33:34 obmyth ivtvfb0 info: ivtvfb_check_var Mar 8 20:33:34 obmyth ivtvfb0 info: Display size: 720x480 (virtual 720x480) @ 32bpp Mar 8 20:33:34 obmyth ivtvfb0 info: Display position: 1, 1 Mar 8 20:33:34 obmyth ivtvfb0 info: Display filter: on Mar 8 20:33:34 obmyth ivtvfb0 info: Color space: RGB Mar 8 20:33:34 obmyth ivtvfb0 info: ivtvfb_get_fix Mar 8 20:33:34 obmyth ivtvfb0 info: ivtvfb_set_par Mar 8 20:33:34 obmyth ivtvfb0 info: ivtvfb_set_var Mar 8 20:33:34 obmyth ivtvfb0 info: Display size: 720x480 (virtual 720x480) @ 32bpp Mar 8 20:33:34 obmyth ivtvfb0 info: Display position: 1, 1 Mar 8 20:33:34 obmyth ivtvfb0 info: Display filter: on Mar 8 20:33:34 obmyth ivtvfb0 info: Color space: RGB Mar 8 20:33:34 obmyth ivtvfb0 info: ivtvfb_get_fix Mar 8 20:33:34 obmyth ivtvfb0 info: Set blanking mode : 0 Mar 8 20:33:34 obmyth ivtvfb0: Framebuffer registered on ivtv card id 0 Mar 8 20:33:35 obmyth ivtvfb0 info: Set blanking mode : 0 Mar 8 20:33:35 obmyth ivtvfb0 info: ivtvfb_check_var Mar 8 20:33:35 obmyth ivtvfb0 info: ivtvfb_check_var Mar 8 20:33:35 obmyth ivtvfb0 info: Display size: 720x480 (virtual 720x480) @ 32bpp Mar 8 20:33:35 obmyth ivtvfb0 info: Display position: 1, 1 Mar 8 20:33:35 obmyth ivtvfb0 info: Display filter: on Mar 8 20:33:35 obmyth ivtvfb0 info: Color space: RGB Mar 8 20:33:35 obmyth ivtvfb0 info: ivtvfb_check_var Mar 8 20:33:35 obmyth ivtvfb0 info: ivtvfb_check_var Mar 8 20:33:35 obmyth ivtvfb0 info: Display size: 720x480 (virtual 720x480) @ 32bpp Mar 8 20:33:35 obmyth ivtvfb0 info: Display position: 1, 1 Mar 8 20:33:35 obmyth ivtvfb0 info: Display filter: on Mar 8 20:33:35 obmyth ivtvfb0 info: Color space: RGB Mar 8 20:33:35 obmyth ivtvfb0 info: ivtvfb_set_par Mar 8 20:33:35 obmyth ivtvfb0 info: ivtvfb_set_var Mar 8 20:33:35 obmyth ivtvfb0 info: Display size: 720x480 (virtual 720x480) @ 32bpp Mar 8 20:33:35 obmyth ivtvfb0 info: Display position: 1, 1 Mar 8 20:33:35 obmyth ivtvfb0 info: Display filter: on Mar 8 20:33:35 obmyth ivtvfb0 info: Color space: RGB Mar 8 20:33:35 obmyth ivtvfb0 info: ivtvfb_get_fix Mar 8 20:33:36 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:36 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 1382400 bytes, 338 pages Mar 8 20:33:36 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:36 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 63428 bytes, 16 pages Mar 8 20:33:37 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:37 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 756068 bytes, 185 pages Mar 8 20:33:37 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:37 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 1382400 bytes, 338 pages Mar 8 20:33:37 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:37 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 63428 bytes, 16 pages Mar 8 20:33:37 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:37 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 1382400 bytes, 338 pages Mar 8 20:33:37 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:37 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 1382400 bytes, 338 pages Mar 8 20:33:39 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:39 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 1382400 bytes, 338 pages Mar 8 20:33:44 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:44 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 1382400 bytes, 338 pages Mar 8 20:33:44 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:33:44 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 1382400 bytes, 338 pages Mar 8 20:34:00 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:34:00 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 91076 bytes, 23 pages Mar 8 20:35:00 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:35:00 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 91076 bytes, 23 pages Mar 8 20:36:00 obmyth ivtvfb0 info: IVTVFB_IOC_DMA_FRAME Mar 8 20:36:00 obmyth ivtvfb0 info: ivtvfb_prep_dec_dma_to_device, 91076 bytes, 23 pages -------------------------------------------------------------------------------------------------------------------------------------------- _______________________________________________ ivtv-users mailing list [email protected] http://ivtvdriver.org/mailman/listinfo/ivtv-users
