Other Parts Discussed in Thread: AM5728
Hi,
EVM: Ti AM5728 evm
Kernel: 4.4.41
I tested the pipeline indicate in this web page:
processors.wiki.ti.com/.../Processor_Training:_Multimedia
Pipeline:
Gst-launch-1.0 -v v4l2src device = / dev / video1 num-buffers = 900 io-mode = 4! 'Video / x-raw, \
Format = (string) YUY2, width = (int) 1280, height = (int) 720 '! Vpe num-input-buffers = 8! Tail! kmssink
In fact it does not work, here is the error that I met after execution:
Root @ am57xx-evm: ~ # gst-launch-1.0 -v v4l2src device = / dev / video1 num-buffers = 900 io-mode = 4! 'Video / x-raw, \
> Format = (string) YUY2, width = (int) 1280, height = (int) 720 '! Vpe num-input-buffers = 8! Tail! kmssink
Setting pipeline to PAUSED ...
Pipeline is live and does not need PREROLL ...
Setting pipeline to PLAYING ...
New clock: GstSystemClock
ERROR: from element / GstPipeline: pipeline0 / GstV4l2Src: v4l2src0: Internal data flow error.
