Hi,
I trying to compile latest pjsip with ffmpeg libs compiled for ios, but get
linking error.
I use following params, not sure if SDL is essential for ios video:
/configure-iphone --disable-sdl --disable-v4l2 --with
ffmpeg=/Users/iphone/video/ffmpeg-iphone
make dep && make clean && make
Here is the configure output:
Using ffmpeg prefix... /Users/iphone/video/ffmpeg-iphone
checking for avdevice_version in -lavdevice... yes
checking for av_register_all in -lavformat... no
checking for avcodec_init in -lavcodec... no
checking for sws_scale in -lswscale... yes
checking for av_malloc in -lavutil... yes
checking for avcore_version in -lavcore... no
checking for v4l2_open in -lv4l2... no
Here is the make output:
ld: warning: -force_cpusubtype_ALL will become unsupported for ARM
architectures
