Hi:
The problem is you have to tell v4l2 which one is the right reference for
your pixel format. I think they have already added, but if you have this
problem please check it.
Open pjmedia/src/pjmedia-videodev/*v4l2_dev.c *replace this table :
static vid4lin_fmt_map v4l2_fmt_maps[] =
{
{ PJMEDIA_FORMAT_YV12, V4L2_PIX_FMT_YVU420 },
{ PJMEDIA_FORMAT_RGB24, V4L2_PIX_FMT_BGR24 },
{ PJMEDIA_FORMAT_RGBA, V4L2_PIX_FMT_BGR32 },
{ PJMEDIA_FORMAT_RGB32, V4L2_PIX_FMT_BGR32 },
{ PJMEDIA_FORMAT_AYUV, V4L2_PIX_FMT_YUV32 },
{ PJMEDIA_FORMAT_YUY2, V4L2_PIX_FMT_YUYV },
{ PJMEDIA_FORMAT_UYVY, V4L2_PIX_FMT_UYVY },
{ PJMEDIA_FORMAT_IYUV, V4L2_PIX_FMT_YUV420 }
};
Hi:
I am still playing with pjsip 2.0 with the video. I am triying to setup de
camera under linux, but I have a problem. When I run ./vstreamutil.c I get
the next output.
16:43:50.888 v4l2_dev.c Found capture device UVC Camera (046d:0990)
16:43:50.889 v4l2_dev.c Enumerating formats:
16:43:52.211 v4l2_dev.c Unsupported: MJPEG
16:43:52.211 v4l2_dev.c Supported: YUV 4:2:2 (YUYV)
16:43:52.211 v4l2_dev.c Unsupported: RGB3
16:43:52.211 v4l2_dev.c Supported: BGR3
16:43:52.211 v4l2_dev.c Unsupported: YU12
16:43:52.211 v4l2_dev.c Unsupported: YV12
16:43:52.211 v4l2_dev.c Video4Linux2 initialized with 1 devices
16:43:52.211 colorbar_dev.c Colorbar video src initialized with 1 devices:
16:43:52.211 sdl_dev.c SDL initialized
and as ffmpeg only suppor I420 and YV12 (if I am not wrong) I get the
problem that the pixel format from the camera and the codec doesn' t match
so it launchs an error.
>From my point of view I think that mz v4l2 is doing something wrong because
when I look the dev I see some references to YV12 but it sais that is
unsupported.
Could you help me?
Regards
Jorge
