Setting ffmpeg_branding = "Chrome" is what causes a compilation error
(see [1], where h264_cabac.c is included):
../../third_party/ffmpeg/libavcodec/x86/cabac.h:193:9: error: inline assembly requires more registers than available
BRANCHLESS_GET_CABAC("%0", "%q0", "(%4)", "%1", "%w1",
[...]
See: https://build.chromium.org/p/tryserver.webrtc/builders/linux32_dbg/builds/50.
Also, from the compililation error, this might be a bug on clang?
...
clang: note: diagnostic msg: PLEASE submit a bug report to http://llvm.org/bugs/ and include the crash backtrace, preprocessed source, and associated run script.
