Hi,everyone!

I have a DM3730 board, and I want to trasmit some video data to webserver with GStreamer

the website  is about example GSstreamer pipelines ,http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines#OMAP35x

 I have referenced the related Video command , as follows:

gst-launch -v v4l2src always-copy=FALSE num-buffers=2000 ! TIVidenc1 codecName=h264enc engineName=hmjcp contiguousInputF

rame=TRUE byteStream=FALSE ! qtmux ! filesink location=sample.mp4 

error as follows:

......................................

(Ldiv0+0x8/0x10)

[14159.497985] Division by zero in kernel.

ERROR: Pipeline doesn't want to pause.

Additional debug info:

Why ? What should to be done for this problem?

Hope help

    Hi Yang,

            I have the same problem. Have you solved the problem? I used DM3730 + OV5640 + gstreamer for video capture test. and used rtp for sending.

           I used the follow command：

    gst-launch -v v4l2src device=/dev/video2 !\
    ffmpegcolorspace !\
    video/x-raw-yuv,format=\(fourcc\)UYVY !\
    TIVidenc1 codecName=h264enc engineName=codecServer !\
    rtph264pay pt=96 ! udpsink host=192.168.2.32 port=7000 sync=false async=false

      and the print :

    libv4lcontrol: error getting username using uid instead: No such file or directory
    ERROR: Pipeline doesn't want to pause.
    ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Device '/dev/video2' cannot capture at 32768x32768
    Additional debug info:
    gstv4l2object.c(2082): gst_v4l2_object_set_format (): /GstPipeline:pipeline0/GstV4l2Src:v4l2src0:
    Call to S_FMT failed for YU12 @ 32768x32768: Invalid argument
    Setting pipeline to NULL ...
    Freeing pipeline ...

    My main aim is stream video by gstreamer via rtsp.
    Can somebody help me?
    BR.
