does anybody by chance know if gstreamer handles the interlaced v4l2 formats correctly and deinterlaces it?
larsc: It will detect it and deinterlace if the deinterlace element is preset in the pipeline.
ok, thanks.
hverkuil: Hi Hans! Is VB2_MMAP io_mode valid for exporting via dma_buf sharing APIs - I am debugging pagefault when the user tries to import.  Exporting driver supports VB2_MMAP (V4L2_MEMORY_MMAP)
Yes, that's valid.
Which kernel version are you using?
thanks
hello. Is it necessary to set a format through  xioctl(fd, VIDIOC_G_FMT, &fmt) before allocating a mmap buffer, or can I set it on the fly?
(same question for the resolution)
