  • 2d7007153   [media] media: videobuf2: Restructure vb2_buffer ... Browse Code »

    Remove v4l2 stuff - v4l2_buf, v4l2_plane - from struct vb2_buffer.

    Add new member variables - bytesused, length, offset, userptr, fd,
    data_offset - to struct vb2_plane in order to cover all information
    of v4l2_plane.
    struct vb2_plane {

    unsigned int bytesused;
    unsigned int length;
    union {
    unsigned int offset;
    unsigned long userptr;
    int fd;
    } m;
    unsigned int data_offset;
    }

    Replace v4l2_buf with new member variables - index, type, memory - which
    are common fields for buffer management.
    struct vb2_buffer {

    unsigned int index;
    unsigned int type;
    unsigned int memory;
    unsigned int num_planes;
    struct vb2_plane planes[VIDEO_MAX_PLANES];

    };

    v4l2 specific fields - flags, field, timestamp, timecode,
    sequence - are moved to vb2_v4l2_buffer in videobuf2-v4l2.c
    struct vb2_v4l2_buffer {
    struct vb2_buffer vb2_buf;

    __u32 flags;
    __u32 field;
    struct timeval timestamp;
    struct v4l2_timecode timecode;
    __u32 sequence;
    };

    Make videobuf2-v4l2 as a wrapper of videobuf2-core for v4l2-use.
    And replace videobuf2-core.h with videobuf2-v4l2.h.
    This renaming change should be accompanied by the modifications
    of all device drivers that include videobuf2-core.h.
    It can be done with just running this shell script.

    replace()
    {
    str1=$1
    str2=$2
    dir=$3
    for file in $(find $dir -name *.h -o -name *.c -o -name Makefile)
    do
    echo $file
    sed "s/$str1/$str2/g" $file > $file.out
    mv $file.out $file
    done
    }

    replace "videobuf2-core" "videobuf2-v4l2" "include/media/"
    replace "videobuf2-core" "videobuf2-v4l2" "drivers/media/"
    replace "videobuf2-core" "videobuf2-v4l2" "drivers/usb/gadget/"
    replace "videobuf2-core" "videobuf2-v4l2" "drivers/staging/media/"

  • 8e6e8f93f   [media] V4L: Add mem2mem ioctl and file operation helpers ... Browse Code »

    This patch adds ioctl helpers to the V4L2 mem-to-mem API, so we can avoid
    several ioctl handlers in the mem-to-mem video node drivers that are simply
    a pass-through to the v4l2_m2m_* calls. These helpers will only be useful
    for drivers that use same mutex for both OUTPUT and CAPTURE queue, which
    is the case for all currently in tree v4l2 m2m drivers. In order to use
    the helpers the drivers are required to use struct v4l2_fh.

  • 33bdd5a88   [media] mem2mem: add support for hardware buffered queue ... Browse Code »

    On mem2mem decoders with a hardware bitstream ringbuffer, to drain the
    buffer at the end of the stream, remaining frames might need to be decoded
    from the bitstream buffer without additional input buffers being provided.
    To achieve this, allow a queue to be marked as buffered by the driver, and
    allow scheduling of device_runs when buffered ready queues are empty.
    This also allows a driver to copy input buffers into their bitstream
    ringbuffer and immediately mark them as done to be dequeued.
    The motivation for this patch is hardware assisted h.264 reordering support
    in the coda driver. For high profile streams, the coda can hold back
    out-of-order frames, causing a few mem2mem device runs in the beginning, that
    don't produce any decompressed buffer at the v4l2 capture side. At the same
    time, the last few frames can be decoded from the bitstream with mem2mem device
    runs that don't need a new input buffer at the v4l2 output side. The decoder
    command ioctl can be used to put the decoder into the ringbuffer draining
    end-of-stream mode.

  • 7f98639de   V4L/DVB: add memory-to-memory device helper framework for videobuf ... Browse Code »

    A mem-to-mem device is a device that uses memory buffers passed by
    userspace applications for both their source and destination data. This
    is different from existing drivers, which utilize memory buffers for either
    input or output, but not both.

    In terms of V4L2 such a device would be both of OUTPUT and CAPTURE type.

    Examples of such devices would be: image 'resizers', 'rotators',
    'colorspace converters', etc.

    This patch adds a separate Kconfig sub-menu for mem-to-mem devices as well.
