Hello everyone 

I just try to build IOS webrtc with h264 support .

Unfortunately I can not make it work

gn gen out/ios_release --args='target_os="ios" target_cpu="arm64" is_debug=false use_rtti=true proprietary_codecs=true rtc_use_h264=true rtc_include_tests=false' --ide=xcode

first I meet some problem  
then  I did some fix

like 

build/config/chrome_build.gni

 is_chrome_branded = false -> is_chrome_branded = true



create a file if not you will get (fatal error: 'libavutil/avconfig.h' file not found)

src/third_party/ffmpeg/libavutil/avconfig.h

/* Generated by ffconf */
#ifndef AVUTIL_AVCONFIG_H
#define AVUTIL_AVCONFIG_H
#define AV_HAVE_BIGENDIAN 0
#define AV_HAVE_FAST_UNALIGNED 0
#endif /* AVUTIL_AVCONFIG_H */





then I meet this

[57/653] LIBTOOL-STATIC obj/third_party/ffmpeg/libffmpeg_internal.a

FAILED: obj/third_party/ffmpeg/libffmpeg_internal.a 

rm -f obj/third_party/ffmpeg/libffmpeg_internal.a && TOOL_VERSION=1553854376 python ../../build/toolchain/mac/filter_libtool.py libtool -static  -o obj/third_party/ffmpeg/libffmpeg_internal.a -filelist obj/third_party/ffmpeg/libffmpeg_internal.a.rsp

fatal error: /Applications/Xcode.app/Contents/Developer/Toolchains/XcodeDefault.xctoolchain/usr/bin/libtool: file list file: obj/third_party/ffmpeg/libffmpeg_internal.a.rsp is empty

[60/653] CXX clang_x64/obj/third_party/protobuf/protobuf_full/datapiece.o

ninja: build stopped: subcommand failed.








now what can I do next ?

I think webrtc has build-in h264 support for ios, no need to include ffmpeg like other platform, we've success turn on h264 native support with Videotoolbox build in webrtc

In general yes but for simulcast video toolbox is not working (

I have the same question.  
In order to achieve WebRTC iOS SIMULCAST H264, I use VIDETOOLBOX and SIMULCASTENCODERADAPTER to solve this problem.
