Hi Guys, (I'm copying Ezequial on this because of the work he has done on the stk1160). My colleague (a Doctor) had this to say on the medical images I posted earlier (see below): The impactVCB-e image is redder and less clear. The dvc100 and easycap seem similar to me and both of them

I looked at the pictures as well and I noticed a few things: The aspect ratio of the impactvcb-e isn't right, it's too narrow. What width and height did you specify when capturing? I can't test this myself as I'm abroad, but try 720x480 or 768x480. I also noticed that the cx23885 driver selects

[PATCH] videobuf2-dma-sg: Fix NULL pointer dereference BUG

2014-04-25 Thread Ricardo Ribalda Delgado
vb2_get_vma() copy the content of the vma to a new structure but set some of its pointers to NULL. One of this pointer is used by follow_pte() called by follow_pfn() on io memory. This can lead to a NULL pointer derreference. The version of vma that has not been cleared must be used. [

ivtv_yuv_init() is used in atomic context, so memory allocation should be done keeping that in mind. Call graph for ivtv_yuv_init() is as follows: - ivtv_yuv_next_free() - ivtv_yuv_prep_frame() [ioctl handler] - ivtv_yuv_setup_stream_frame() - ivtv_irq_dec_data_req() - ivtv_irq_handler()

Is the as102 tree ever likely to go mainline? The only reason it's in staging is because it doesn't meet the coding standards (i.e. whitespace, variable naming, etc). Somebody needs to come along and expend the energy to satisfy the whitespace gods. Seems like a fantastically stupid reason to
