onRequestKeyFrame method

FutureOr<void> onRequestKeyFrame(dynamic streamId, dynamic streamInfo, dynamic videoIndex)

@detail callback @author wangzhanqiang @brief 提示流发布端需重新生成关键帧的回调 @param streamId 远端编码流的 ID @param streamInfo 远端编码流的属性 @param videoIndex 对应编码流的下标

Implementation

FutureOr<void> onRequestKeyFrame(
    dynamic streamId, dynamic streamInfo, dynamic videoIndex) async {
  if ($instance == null || $instance is! IExternalVideoEncoderEventHandler) {
    return;
  }
  return ($instance as IExternalVideoEncoderEventHandler)
      .onRequestKeyFrame
      ?.call(streamId.toString(), int.tryParse(videoIndex.toString()) ?? 0);
}
