生成native-lib_arm64-v8a：错误：没有匹配的函数调用'av_rescale_q_rnd'

问题描述

我正在尝试编译我的native-lib.cpp，但我一直收到此错误。这里的问题是参数

pkt.pts = av_rescale_q_rnd(pkt.pts,in_stream->time_base,out_stream->time_base,(AVRounding)(AV_ROUND_NEAR_INF|AV_ROUND_PASS_MINMAX));
        pkt.dts = av_rescale_q_rnd(pkt.dts,(AVRounding)(AV_ROUND_NEAR_INF|AV_ROUND_PASS_MINMAX));
        pkt.duration = av_rescale_q(pkt.duration,out_stream->time_base);

我得到的错误

从上面的错误中我认为它似乎仅针对arm64-v8抛出

app\src\main\libs\arm64-v8a\include\libavutil\mathematics.h:151:9: note: candidate function not viable: no kNown conversion from 'AVRational *' to 'AVRational' for 2nd argument; dereference the argument with *

因为这是一个ffmpeg示例代码块，所以我没有做任何更改。仅当我尝试生成签名的apk时，Android Studio才会引发错误，并且我可以在我的Android 6设备中正常运行此错误。

我尝试将in_stream->time_base,out_stream->time_base替换为*in_stream->time_base,*out_stream->time_base，这会引发其他类型的错误

app\src\main\cpp\native-lib.cpp:716:45: error: indirection requires pointer operand ('AVRational' invalid)
