building errors

[melody-rain]

With following commands:

bazel build -c opt --config=android_arm64     mediapipe/examples/android/src/java/com/google/mediapipe/apps/facedetectiongpu     --incompatible_depset_is_not_iterable=false     --incompatible_disable_deprecated_attr_params=false     --incompatible_no_support_tools_in_action_inputs=false

I always get errors:

melody-rain@, this issue probably can be solved by modifying third_party/ffmpeg_linux.BUILD and
third_party/opencv_linux.BUILD like the following:

Let me know if that works. If it does, we will fix this in the next release. Thanks.

@jiuqiant I can build it now. Thanks.
