error: ‘I420Buffer’ is not a member of ‘webrtc’

ubuntu16.04 download your prebuild webrtc version https://github.com/sourcey/webrtc-precompiled-builds/blob/master/webrtc-18252-6294a7e-linux-x64.json and cmake using:

cmake .. -DWEBRTC_ROOT_DIR=/home/demobin/work/github/libwebrtc -DCMAKE_BUILD_TYPE=DEBUG -DBUILD_SHARED_LIBS=OFF \
         -DBUILD_MODULES=OFF -DBUILD_APPLICATIONS=OFF \
         -DBUILD_SAMPLES=OFF -DBUILD_TESTS=OFF \
         -DWITH_WEBRTC=ON -DWITH_FFMPEG=ON \
         -DBUILD_MODULE_base=ON -DBUILD_MODULE_crypto=ON \

         -DBUILD_MODULE_util=ON -DBUILD_MODULE_uv=ON \
         -DBUILD_MODULE_webrtc=ON

then make, i got these error:

any suggestion?

The buffer class was changed recently... Which prebuilt library version are you using? You should be able to use the latest prebuilt library without issue.

webrtc-18252-6294a7e-linux-x86.tar.gz is this the latest prebuilt linux webrtc version? i cann't find another except this

[auscaster]

OK it looks like the I420Buffer class still exists in the main repo, it was the VideoFrame class that changed.

Maybe try adding the include

#include "webrtc/api/video/i420_buffer.h"

at the top of

videopacketsource.cpp

[demobin8]

OK! Compile success Thanks!

[auscaster]

Great! Did adding the include work?

I'll need to make a patch

[demobin8]

yes
