avutil/avutil: make AV_TIME_BASE_Q available in C++
ISO C++ forbids compound-literals. It's not available with MSVC. This is a known issue from 10 years ago, and that's why there is a av_get_time_base_q(). Since we have no plan to remove AV_TIME_BASE_Q, just make it available in C++. There are multiple choices: 1. Use C++11 syntax: AVRational{1, AV_TIME_BASE} Users may still use C++98 to write new code. So no. 2. Use av_get_time_base_q(). It's for this purpose. But it's not compile time constants as AV_TIME_BASE_Q in C. So I choose av_make_q() as Anton's suggestion. https://libav-devel.libav.narkive.com/ZQCWfTun/patch-0-2-fix-avutil-h-usage-from-c Signed-off-by: Zhao Zhili <zhilizhao@tencent.com>
