#13391 — [Bug 297454] multimedia/ffmpeg: Fail to build on current since the introduction to video(4)

https://bugs.freebsd.org/bugzilla/show_bug.cgi?id=297454

            Bug ID: 297454
           Summary: multimedia/ffmpeg: Fail to build on current since the
                    introduction to video(4)
           Product: Ports & Packages
           Version: Latest
          Hardware: Any
                OS: Any
            Status: New
          Severity: Affects Only Me
          Priority: ---
         Component: Individual Port(s)
          Assignee: multimedia@FreeBSD.org
          Reporter: monwarez@mailoo.org
          Assignee: multimedia@FreeBSD.org
             Flags: maintainer-feedback?(multimedia@FreeBSD.org)

Since the introduction of https://reviews.freebsd.org/D58367
ffmpeg is seeing the header <sys/videoio.h>, and thus no longer include
<linux/videodev2.h> .
Given that both headers does not define the same sets of pixel format types,
ffmpeg fail to build.

I wonder what would be the best approach, given that we now have both video(4)
and webcamd that is able to generate a /dev/videoN devices and that they does
not seems to have the same capabilities in terms of pixel format, should we
take the minimal set of feature instead ?

This also impacts legacy ffmpeg4 (so we don't forget to clean up the others
while we're here)

This also impacts graphics/opencv, which breaks x11/kde among other things.

I opened D58793, to fix the build. tested against ffmpeg and opencv.

There is mplayer that needs --disable-tv-v4l2, i dont think anyone is using
analog tv with it.

    video: add V4L2 compat symbols for ffmpeg/opencv

    Adds v4l2_std_id, struct v4l2_standard/v4l2_plane, VIDIOC_G_STD/S_STD/
    ENUMSTD, V4L2_STD_NTSC*, the MPLANE capability flag, multiplanar types
    (VIDEO_MAX_PLANES, v4l2_plane_pix_format, v4l2_pix_format_mplane,
    V4L2_TYPE_IS_MULTIPLANAR), V4L2_PIX_FMT_JPEG/YUV411P/SN9C10X, and the
    MPEG control class (V4L2_CID_MPEG_BASE, V4L2_CID_MPEG_VIDEO_B_FRAMES).

    video(4) capture devices are digital-only and never expose these, but
    ffmpeg's libavdevice/v4l2.c and opencv's cap_v4l.cpp both reference
    them unconditionally. Fixes their build against sys/videoio.h.
