avformat_open_input cant handle unicode filename after update to ffmpeg-6 and c++20

Reported by: DarylE Owned by:

Description

Our c++ application (xlights.org) is now failing with unable to open mp3 files when given a filename with unicode characters.
eg. Everybody Want (From “The Hunger Games_ Catching Fire” Soundtrack).mp3

this is our call.

int res = avformat_open_input(&formatContext, _audio_file.c_str(), nullptr, nullptr)

Is there anything we could or should have done to handle this now in this version of avformat?
(windows 64bit, along with Unix and MacOS)

Are you passing the filename as UTF-8?

This is the definition .. 

std::string _audio_file;

Our fix was to go thru the code with ToUTF8(). Weird how this would have changed..

int res = avformat_open_input(&formatContext, ToUTF8(_audio_file).c_str(), nullptr, nullptr);

Maybe this changed the behaviour: 92885f26817b6b2515ac9fd5410c9e8be64bd0c0

In any case, you should pass UTF8 filenames to avformat_open_input, so closing this.
