Please follow instructions below to build C++ command-line example apps in the
|
|
supported MediaPipe [solutions](../solutions/solutions.md). To learn more about
|
|
these example apps, start from [Hello World! in C++](./hello_world_cpp.md).
|
|
|
|
## Building C++ command-line example apps
|
|
|
|
### Option 1: Running on CPU
|
|
|
|
1. To build, for example, [MediaPipe Hands](../solutions/hands.md), run:
|
|
|
|
```bash
|
|
bazel build -c opt --define MEDIAPIPE_DISABLE_GPU=1 mediapipe/examples/desktop/hand_tracking:hand_tracking_cpu
|
|
```
|
|
|
|
2. To run the application:
|
|
|
|
```bash
|
|
GLOG_logtostderr=1 bazel-bin/mediapipe/examples/desktop/hand_tracking/hand_tracking_cpu \
|
|
--calculator_graph_config_file=mediapipe/graphs/hand_tracking/hand_tracking_desktop_live.pbtxt
|
|
```
|
|
|
|
This will open up your webcam as long as it is connected and on. Any errors
|
|
is likely due to your webcam being not accessible.
|
|
|
|
### Option 2: Running on GPU
|
|
|
|
Note: This currently works only on Linux, and please first follow
|
|
[OpenGL ES Setup on Linux Desktop](./gpu_support.md#opengl-es-setup-on-linux-desktop).
|
|
|
|
1. To build, for example, [MediaPipe Hands](../solutions/hands.md), run:
|
|
|
|
```bash
|
|
bazel build -c opt --copt -DMESA_EGL_NO_X11_HEADERS --copt -DEGL_NO_X11 \
|
|
mediapipe/examples/desktop/hand_tracking:hand_tracking_gpu
|
|
```
|
|
|
|
2. To run the application:
|
|
|
|
```bash
|
|
GLOG_logtostderr=1 bazel-bin/mediapipe/examples/desktop/hand_tracking/hand_tracking_gpu \
|
|
--calculator_graph_config_file=mediapipe/graphs/hand_tracking/hand_tracking_desktop_live_gpu.pbtxt
|
|
```
|
|
|
|
This will open up your webcam as long as it is connected and on. Any errors
|
|
is likely due to your webcam being not accessible, or GPU drivers not setup
|
|
properly.
