--- Comment #28 from Nicolas Dufresne (stormer) <nicolas.dufresne at collabora.co.uk> ---
Works now, it also fixes a lot of the issues I was having on nouveau here. The
dirver is probably less robust to us giving wrong larger size.

    glmemory: Provide correct size on upload

    Provide the right size to GL when uploading. Using maxsize is wrong
    since we offset the data point with the memory offset and video
    alignement offset.

    glmemory: Provide correct size on download

    Provide the right size to GL when downloading. This fixes downloading
    from GLMemory that where created for libav.

    glmemory: Use fallback for partial copy

    When the memory is partial copy, the texture size and videoinfo no
    longer make sense. As we cannot guess what the application wants, we
    safely copy into a sysmem memory.

    glmemory: Add GstAllocationParams and alignment support

    This implements support for GstAllocationParams and memory alignments.
    The parameters where simply ignored which could lead to crash on
    certain platform when used with libav and no luck.
