Examples for RZ/G2L

Down Scaling using vspmfilter

  • Below table show range of support:
Supported solution range
Input resolution Output scale down ratio
Min 128x72 1
Max 1920x1080 15

Following are sample commands for Up/Down Scaling with h264 Elementary Stream file.

Case of Down Scaling

gst-launch-1.0 filesrc location=./<FullHDsize_h264_file> ! h264parse ! queue ! omxh264dec ! queue ! vspmfilter outbuf-alloc=true ! video/x-raw, format=BGRA, width=1280, height=720 ! waylandsink

Case of Down Scaling (without color format conversion)

gst-launch-1.0 filesrc location=./<FullHDsize_h264_file> ! h264parse ! queue ! omxh264dec ! queue ! vspmfilter outbuf-alloc=true ! video/x-raw, width=1280, height=720 ! waylandsink

Case of Down Scaling (without color format conversion – use dmabuf)

gst-launch-1.0 filesrc location=./<FullHDsize_h264_file> ! h264parse ! queue ! omxh264dec ! queue ! vspmfilter dmabuf-use=true ! video/x-raw, width=1280, height=720 ! waylandsink

Color format conversion using vspmfilter

  • Below table show color format conversion using vspmfilter:
Supported color format
No. Supported color format
1 BGRA
2 BGRx
3 RGB16
4 YUY2
5 NV12

Following are sample commands for converting color format. Please set the output format which begin supported following “format=”.

Case of BGRA output

gst-launch-1.0 filesrc location=filename.mp4 ! qtdemux ! queue ! h264parse ! omxh264dec ! queue ! vspmfilter outbuf-alloc=true ! video/x-raw, format=BGRA ! waylandsink
