Other Parts Discussed in Thread: TVP5146

hi there !

i have been trying to run H.264 encoder with leopard imaging board LI-TB02 using DM368 with ridgerun demo image for TVP5146 composite input.

here is my gstreamer pipeline

gst-launch -v v4l2src input-src=composite chain-ipipe=true always-copy=false queue-size=6 ! 'video/x-raw-yuv,format=(fourcc)NV12, width=736, height=576' !

dmaiaccel ! dmaienc_h264 targetbitrate=6000000 bytestream=true copyOutput=false single-nalu=true encodingpreset=2 entropy=0 intraframeinterval=14 idrinterval=10

ratecontrol=2 ! rtph264pay ! udpsink host=199.200.15.61 port=6666 sync=false enable-last-buffer=false

getting reasonable delay and acceptable quality but a small portion of video (approx 80 to 100 pixels) of left side of the image are shown on the right hand side. image and

video attached for illustration.

here is the video

i wrote the video to a file and played the video on vlc but same results,

i am using sdp file with vlc to stream the video on windows pc.

sdp contents are as under:-

o= IN IP4 199.200.15.61
m=video 6666 RTP/AVP 96
c=IN IP4 199.200.15.61
a=rtpmap:96 H264/90000

Hello,

On Ridgerun's page for "TVP5146 GStreamer example pipelines" I see this pipeline is given as example.

HOST_IP=10.111.0.4

gst-launch -v v4l2src always-copy=FALSE input-src=composite ! priority scheduler=1 rtpriority=40 ! "video/x-raw-yuv,format=(fourcc)NV12,width=720,height=480,pitch=736" ! dmaiaccel ! dmaienc_h264 targetbitrate=800000 ! dmaiperf ! rtph264pay ! udpsink host=$HOST_IP port=3000



I would recommend you to check these threads also:

Hello,

In additional, I would recommend you to try pipeline only capture->save in file to check is the problem comes from the capture side.

Best Regards,

Thanks Margaret,

i tried said pipeline

gst-launch -v v4l2src always-copy=FALSE input-src=composite ! priority scheduler=1 rtpriority=40 ! "video/x-raw-yuv,format=(fourcc)NV12,width=720,height=480,pitch=736" ! dmaiaccel ! dmaienc_h264 targetbitrate=800000 ! dmaiperf ! rtph264pay ! udpsink host=$HOST_IP port=3000

but the video shift is still there.

secondly, i tried your suggestion (capture->save ), i used following pipeline to capture raw image/video and used yuv player tool to play that yuv raw video file.

gst-launch -e v4l2src input-src=composite always-copy=false num-buffers=50 ! 'video/x-raw-yuv, height=576,width=736'! ffmpegcolorspace ! filesink location=
/t2.raw
