HarmonyOS 视频解码的时候OH_VideoDecoder_RenderOutputBuffer方法一直返回为2

参考官方案例，使用XComponent渲染解码后的视频，但是解码的方法OH_VideoDecoder_RenderOutputBuffer一直返回2，导致demo没有画面。

代码：

int32_t VideoDecoder::FreeOutputData(uint32_t bufferIndex, bool render)
{
  if (decoder == nullptr) {
    OH_LOG_ERROR(LOG_APP, "Decoder is null");
    return AV_ERR_UNKNOWN;
  }

  int32_t ret = AV_ERR_OK;
  if (render) {
    ret = OH_VideoDecoder_RenderOutputBuffer(decoder, bufferIndex);
  } else {
    ret = OH_VideoDecoder_FreeOutputBuffer(decoder, bufferIndex);
  }
  if (ret != AV_ERR_OK) {
    OH_LOG_ERROR(LOG_APP, "Free output data failed： ret=%{public}d", ret);
    return AV_ERR_UNKNOWN;
  }
  return AV_ERR_OK;
}
int32_t ret = videoDecoder_->FreeOutputData(bufferInfo.bufferIndex, true);
if (ret != AV_ERR_OK) {
  OH_LOG_ERROR(LOG_APP, "Decoder output thread out");
  break;
}

结果：
