[FFmpeg-user] Unknown Option "--enable-libwavpack"

2020-10-02 Thread 桃源老師
Hello, I pulled current git head 45070eec4c089b06947f07e25cdb1bc8b2102553, and do configure, then encountered configure error, Unknown Option "--enable-libwavpack". With git log command, it seems that libwavpack was removed. Is it true? Best Regards, // Miya aka. TougenRoushi
