dm365 video streaming compressed on dvsdk4

Other Parts Discussed in Thread: TVP5151, TVP5150

Sorry for my not enough gstreamer knowledge (I'm improving it...).

tvp5151 works on my custom board and I can get video using this command:

gst-launch v4l2src ! 'video/x-raw-yuv, format=(fourcc)UYVY, fr
amerate=(fraction)60/1, width=(int)720, height=(int)480' ! ffmpegcolorspace ! filesink location=video_19_11_2010_003.raw

I can see the video on the host using this command:

mplayer -fps 6 video_19_11_2010_002.raw -demuxer rawvideo -rawvideo w=720:h=480:format=uyvy

I'm working with the arago kernel and loadmodules ok (mem=60M).
 I'd like to stream to windows in mpeg4/h264 in the easiest way.
 I guess gstreamer-ti+mpeg4+vlc on win O.S.
Looking at http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines I guess that the info are to be updated.
It doesn't matter anyway...

Now I have found in targetfs some examples:
 find target_fs/ -name "gst*"
 target_fs/home/root/dm365/matrix/bin/gst_encode_h264
 target_fs/home/root/dm365/matrix/bin/gst_decode_mp4
 target_fs/home/root/dm365/matrix/bin/gst_decode_h264
 target_fs/home/root/dm365/matrix/bin/gst_decode_mpeg4
 target_fs/home/root/dm365/matrix/bin/gst_passthru
 target_fs/home/root/dm365/matrix/bin/gst_decode_mpeg2

and I'm trying to move from the following working command:

gst-launch v4l2src ! 'video/x-raw-yuv, format=(fourcc)UYVY, fr
 amerate=(fraction)60/1, width=(int)720, height=(int)480' ! ffmpegcolorspace ! fi
 lesink location=video_19_11_2010_003.raw

to the streaming example in http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines, that is:
 gst-launch -v v4l2src always-copy=FALSE ! TIVidenc codecName=h264enc engineName=hmjcp contiguousInputFrame=TRUE ! rtph264pay pt=96 ! udpsink host=<HOST_PC_IP> port=5000

passing from /home/root/dm365/matrix/bin/gst_encode_h264 example:
 gst-launch v4l2src always-copy=FALSE num-buffers=500 ! 'video/x-raw-yuv, format=(fourcc)NV12, framerate=(fraction)60/1, width=(int)1280, height=(int)720' ! tee name=t ! queue ! TIVidenc1 codecName=h264enc engineName=codecServer contiguousInputFrame=TRUE bitRate=600000 ! filesink location=/home/root/GStreamer_encoded_file.264 t. ! queue ! TIDmaiVideoSink videoStd=720P_60 videoOutput=component sync=false hideOSD=true contiguousInputFrame=TRUE -v

I really need NV12 or I can use UYVY  ?
 If use UYVY the resizer is not happy:
 davinci_resizer davinci_resizer.2: Operation mode doesn't match with current hw mode
Any idea?

bye,
Raffaele

    Hi Raffele,

    Unfortunately the codec does not support UYVY. NV12 is the only supported colorspace.

    Best regards,

    Vincent

    who can help me ?thanks,

    I don't know if  it is relate to /dev/fb*  ,

    oh,yes, it is relate to /dev/fb* . you can use "DMAI_DEBUG = 2     ./you program" to get detial information.

    then ,you can create /dev/fb*  .(may be ).
