Introduction
DM81xx
Encode videotest pattern in H.264 (without container)
gst-launch-1.0 videotestsrc num-buffers=1000 ! omxbufferalloc num-buffers=8 ! omxh264enc ! perf print-arm-load=true ! filesink location=sample.h264
Scale the QVGA video test pattern to VGA
gst-launch-1.0 videotestsrc num-buffers=1000 ! 'video/x-raw,format=(string)NV12,width=320,height=240,framerate=(fraction)60/1' ! omxbufferalloc num-buffers=8 ! omxscaler ! 'video/x-raw,format=(string)YUY2,width=640,height=480,framerate=(fraction)60/1' ! perf print-arm-load=true ! fakesink
DM8148
V4l2 Capture and recording
gst-launch-1.0 v4l2src io-mode=3 device=/dev/video0 num-buffers=1000 ! 'video/x-raw,format=(string)NV12,width=1280,height=720,framerate=(fraction)60/1' ! perf print-arm-load=true ! omxbufferalloc num-buffers=12 -v ! omxh264enc i-period=30 idr-period=30 ! queue ! rrh264parser single-nalu=true ! mp4mux dts-method=0 ! filesink location=test_v4l2src_1.0.mp4
V4l2 Capture and UDP streaming
These instructions show how to do video streaming over the network, a video will be captured on the board and viewed on the host. These pipelines use the port that you configure to send the packets. To configure the port and the host ip to send the streaming you have to set the variables port=$PORT and host=$HOST to your own).
- Server: DM81xx
