Question

我已将GStreamer包含在我的iOS项目中，我收到的一些错误如下：

Undefined symbols for architecture arm64:
  "_kVTCompressionPropertyKey_Quality", referenced from:
      _gst_vtenc_set_quality in GStreamer(libgstapplemedia_a_arm64_-libgstapplemedia_la-vtenc.o)

ld: symbol(s) not found for architecture arm64
clang: error: linker command failed with exit code 1 (use -v to see invocation)

我已经包含在构建阶段库中，例如：

GStreamer.framework
libiconv.tbd
libresolv.tbd
libstdc++.6.0.9.tbd

但我仍然明白。有什么建议吗？

Answer 1

您需要将项目与VideoToolbox.framework相关联，因为错误中的符号（VTCompressionSessionInvalidate，VTCompressionPropertyKey_Quality）已在其中定义。

GStreamer
