Hello I`m try to build PJSIP 2.10 as static library with FFMEG 3.4 (static) and get error: ``` ../src/pjmedia/converter_libswscale.c:81:24: error: storage size of ‘srcFormat’ isn’t known enum AVPixelFormat srcFormat, dstFormat; ^ ../src/pjmedia/converter_libswscale.c:81:35: error: storage size of ‘dstFormat’ isn’t known enum AVPixelFormat srcFormat, dstFormat; ^ ../src/pjmedia/converter_libswscale.c:124:70: error: type of formal parameter 3 is incomplete sws_ctx = sws_getContext(src_detail->size.w, src_detail->size.h, srcFormat, ^ ../src/pjmedia/converter_libswscale.c:125:56: error: type of formal parameter 6 is incomplete dst_detail->size.w, dst_detail->size.h, dstFormat, ^ ``` When i run ./configure I get this message: ``` Using ffmpeg prefix... /home/pi/ffmpeg_build checking for pkg-config... pkg-config checking ffmpeg packages... libavdevice libavformat libavcodec libswscale libavutil checking for enum AVPixelFormat... no ``` "AVPixelFormat... no" BUT if I change ffmpeg version to 4.10 it still appears. in my `pjlib/include/pj/config_site.h` I set this: ``` #define PJMEDIA_HAS_VIDEO 1 #define PJMEDIA_HAS_FFMPEG 1 ``` I see that `-DPJMEDIA_USE_OLD_FFMPEG=1` How can I fix these errors?
