omx_mjpegdec problem

sphone pan
Prodigy 180 points

Hi,
I'm trying to render a mjpeg stream using gstreamer on DM8148 EVM.
First, I enter following command ,and it can work success.
root@dm814x-evm:~#gst-launch -v v4l2src ! image/jpeg,width=640,height=480 ! jpegdec
! ffmpegcolorspace ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! omx_videosink
sync=false
Then ,I exec the command "gst-inspect omx_mjpegdec",and show the following:
        Factory Details:
        Long name: OpenMAX IL JPEG/MJPEG decoder
       Class: Codec/Decoder/Video
       Description: Decodes video/images in MJPEG/JPEG format with OpenMAX IL
       Author(s): Felipe Contreras
        Rank: primary (256)
It means that omx_mjpegdec can decode the jpeg format picture.
So I want to use omx_mjpegdec substitute jpegdec,
root@dm814x-evm:~# gst-launch -v v4l2src ! image/jpeg,width=640,height=480 ! omx_mjpegdec !
omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! omx_videosink sync=false

But it error:

/GstPipeline:pipeline0/GstV4l2Src:v4l2src0.GstPad:src: caps = image/jpeg, width=(int)640,

Could anyone tell me the error reason and how I can use omx_mjpegdec success.

Thanks !

    Hello,

    You could try  below gst pipeline:

    MJPEG in MOV container format

    gst-launch -v filesrc location='test.MOV' ! qtdemux name=demux demux.video_00 ! queue ! omx_mjpegdec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! gstperf ! omx_videosink

    MJPEG Elementry Stream

    gst-launch -v filesrc location= test.jpeg ! typefind ! jpegparse ! omx_mjpegdec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! gstperf ! omx_videosink sync=false

    or you could try for example:

    gst-launch  v4l2src !'image/jpeg, width=640, height=480, framerate=(fraction)30/1' !  ffdec_mjpeg  ! ffmpegcolorspace ! 'video/x-raw-yuv,format (fourcc)YUY2, width=640, height=480, framerate=(fraction)30/1' ! gstperf  ! v4l2sink userpointer=false

    or

    gst-launch  v4l2src !'image/jpeg, width=640, height=480, framerate=(fraction)30/1' !  omx_mjpegdec  ! ffmpegcolorspace ! 'video/x-raw-yuv,format (fourcc)YUY2, width=640, height=480, framerate=(fraction)30/1' ! gstperf  ! v4l2sink userpointer=false

    Best Regards,

    Margarita

    Hello,Margarita Gashova,Thank you for you reply.
    I have try the gst pipleline you suggested.

    1:The gst pipleline is ok.And it work success.
    gst-launch v4l2src !'image/jpeg, width=640, height=480, framerate=(fraction)30/1' ! ffdec_mjpeg ! ffmpegcolorspace !
    'video/x-raw-yuv,format (fourcc)YUY2, width=640, height=480, framerate=(fraction)30/1' ! gstperf ! v4l2sink
    userpointer=false

    ----------------------------------------------
    2:I don't have a *.jpeg picture ,but I have one *.jpg picture. the gst pipleline run fail!
    root@dm814x-evm:~# gst-launch -v filesrc location= img1.jpg ! typefind ! jpegpar
    se ! omx_mjpegdec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! gs

    Hello,

    In most cases this error means  your bootargs are wrong.:

    notify_shm_drv_sendevent failed! status = 0xfffffff2
    notify_send_event failed! status = 0xfffffff2
    notify_shm_drv_sendevent failed! status = 0xfffffff2
    notify_send_event failed! status = 0xfffffff2

    There are separate set of bootargs for EZSDK which should be mentioned in EZSDK user guide.

    Best Regards,

    Margarita

    Hello,

    You could check here about omx_mjpegdec:

    http://e2e.ti.com/support/dsp/davinci_digital_media_processors/f/717/t/207597.aspx

    and let me know the result.

    Hi, Margarita Gashova

    gstreamer in 5.05 has a bug that prevents the gstreamer omx_mjpeg decode component from working. The fix for that is attached to this post and is included in the define SDOCM00097118.

    sdocm00097118.zip

    After I fix it,the following gst pipleline can work,it can decode the mjpeg streamer via omx_mjpegdec

    root@dm814x-evm:~# gst-launch -v filesrc location= test.mjpeg ! typefind ! jpegparse ! omx_mjpegdec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MODE_1080P_60 ! gstperf ! omx_videosink

    But when I was trying decode mjpeg streamer from a usb camera,but it fail..A and B 's results is same .unrecoverable error..........

    A:root@dm814x-evm:~#gst-launch  v4l2src !'image/jpeg, width=640, height=480, framerate=(fraction)24/1' !  omx_mjpegdec  ! ffmpegcolorspace !  video/x-raw-yuv,format (fourcc)YUY2, width=640, height=480 ! gstperf  ! v4l2sink userpointer=false

    B:root@dm814x-evm:~# gst-launch -v v4l2src ! image/jpeg,width=640,height=480 ! typ
    efind ! jpegparse ! omx_mjpegdec ! omx_scaler ! omx_ctrl display-mode=OMX_DC_MO

    the ezsdk version is ezsdk_5_05_01_04,the gst-openmax is lastest get from https://gstreamer.ti.com/svn/gstreamer_ti/trunk/gstreamer_ti_dm81xx

    Could you give me some suggestions.

    Thanks!
