- remove GeneratedPluginRegistrant.java file then remove .gradle/flutter clean/flutter pub get








I have this issue in every version of the plugin. There is something wrong in my configurations or maybe this is a plugin issue ?

When I run

 Stream #0:0: Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, stereo, s16p, 384 kb/s



Meaning that the video and audio streams swapped indices. I'm writing a program which uses
libav
where I rely on this to not happen. What is the reason for this and can it be fixed ?
