why?

Because num_channels was a size_t. But I changed it to an int, so we don't need
this anymore.

+namespace webrtc {
+
+// NOTE: This struct is still under development and may change without notice.
+struct AudioEncoderG722Config {
+  bool IsOk() const {
+    return frame_size_ms > 0 && frame_size_ms % 10 == 0 && num_channels >= 1;
+  }
+  int frame_size_ms = 20;
+  int num_channels = 1;
+};
+
+}  // namespace webrtc

+#endif  // WEBRTC_API_AUDIO_CODECS_AUDIO_ENCODER_G722_CONFIG_H_
