Examples for RZ/G2L
Down Scaling using vspmfilter
- Below table show range of support:
| 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:
| 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
