I want some pipeline examples such as Capture/Encoder/Networking for DM8148 besides those listed in example_pipeline.sh.
Could someone share them here or update the wiki page http://processors.wiki.ti.com/index.php/Example_GStreamer_Pipelines?
Thanks a lot!
Gstreamer Pipelines tested on DM81xx can be found at http://processors.wiki.ti.com/index.php/DM81xx_Gstreamer_Pipelines. This page doesn't have capture+encode+stream pipelines yet since there was no video capture element supported yet in gstreamer port for DM81xx (available at gstreamer.ti.com). This page will be updated with capture+encode+stream pipelines as soon as we have gstreamer element for video capture available.
Thanks
Satish
Satish, this implies that even today there are no Gstreamer elements for video capture available? I would be also interested in capturing with gstreamer!
Hello Tobias,
Gstreamer capturing:
You could use v4l2.
Best Regards,
Margarita
Hello,
Here is example:
gst-launch -v v4l2src always-copy=false queue-size=12 num-buffers=2000 ! 'video/x-raw-yuv-strided,format=(fourcc)NV12,width=1920,height=1080,framerate=(fraction)60/1' ! omxbufferalloc numBuffers=12 ! omx_h264enc bitrate=5000000 ! filesink location=v4l2cap.h264
Best Regards,
Margarita
Margarita, thanks for your example. As I don't have anything connected to the video inputs your pipeline doesn't record anything. But I would like to use a UVC USB Webcam (Logitech 9000) - but I don't get it running, I either get "could not link v2l4src0 to ..." or "Could not negotiate format":

Hello,
"gst-launch -v -e v4l2src always-copy=false device=/dev/video4 ! 'video/x-raw-yuv,format=(fourcc)YUYV,width=640,height=480,framerate=(fraction)30/1' ! ffmpegcolorspace ! fakesink"
WARNING: erroneous pipeline: could not link v4l2src0 to ffmpegcsp0
In this case it means that could not link the v4l2src component. I guess when you don't use ffmpegcolorspace component you get the error: "Could not negotiate format". In both cases it means that your video source is not recognized.
Are you using EZSDK?

yes
It seems to me that its a problem with v4l2src of GST in EZSDK. The camera has following formats:

I used the following pipelines to check functionality
## Record AVI with MJPEG , camera input YUV
gst-launch -v -e v4l2src device=/dev/video4 num-buffers=30 ! video/x-raw-yuv,width=320,height=240,framerate=30/1 ! ffmpegcolorspace ! jpegenc ! avimux ! filesink location=record.avi
## Record AVI with MJPEG, camera input MJPEG
gst-launch -v -e v4l2src device=/dev/video4 num-buffers=30 ! image/jpeg,width=320,height=240,framerate=30/1 ! avimux ! filesink location=video.avi
## Both results in the following error:
## ERROR: from element /GstPipeline:pipeline0/GstV4l2Src:v4l2src0: Could not negotiate format
## Recording to fakesink - just for checking functionality of camera, input YUV
gst-launch -v -e v4l2src device=/dev/video4 num-buffers=30 ! 'video/x-raw-yuv,format=(fourcc)YUYV,width=320,height=240,framerate=(fraction)15/1' ! ffmpegcolorspace ! fakesink
gst-launch -v -e v4l2src device=/dev/video4 num-buffers=30 ! 'video/x-raw-yuv,format=(fourcc)YUYV,width=320,height=240,framerate=(fraction)15/1' ! fakesink
## Both results in the following error:
## WARNING: erroneous pipeline: could not link v4l2src0 to fakesink0
Could the problem be, that the camera has only YUYV, but there is actually no gst-element that supports YUYV? A interesting thing is, the the pipe is working on PC, but there it automatically selects YUV2 as format. Webcam used was a Logitech Pro 9000.
Hi
I am trying to test my camera , but i am getting following issues, can some one help me.
Thanks in advance

Hello Tobias,
This error 'Could not negotiate format' indicates some parameters are not set right in GstV4l2Src/V4l2 driver layer or not supported by camera, but gstreamer component is asking for them. So, it is better to try capture using only V4l2 level, with out Gstreamer and make it work. After that try with Gstreamer. I mean you could try to run saLoopBack demos in EZSDK:
http://processors.wiki.ti.com/index.php/TI81XX_PSP_VIDEO_CAPTURE_Driver_User_Guid
Sample application chapter.
Let me know the result.
Best Regards,
Margarita
