I'm trying to build the most recent obs-studio (say, 27.2.4 ) under Ubuntu 22.04, with ffmpeg 5.0 . But failed with the following ERROR messages:
So, when will obs-studio be compatible with ffmpeg-5.0?

You'll probably want the master branch instead of 27.2.4. We've only recently been adding support for 5.0.

I got it... it looks
C++: 
#if LIBAVCODEC_VERSION_INT >= AV_VERSION_INT(57, 48, 101)
is NOT working properly...

I can tell that
C++: 
LIBAVCODEC_VERSION_MAJOR is equal to 59
, but the above code doesn't work at all..


It's actually this defintion
C++: 
#define AV_VERSION_INT(a, b, c) ((a)<<16 | (b)<<8 | (c))
brings the problem?

Anyway, my ENV:

Bash:

Temparorily, I just modify the above code to:

C++: 
//#if LIBAVCODEC_VERSION_INT >= AV_VERSION_INT(57, 48, 101)
#if (LIBAVCODEC_VERSION_MAJOR > 57) || \
    ((LIBAVCODEC_VERSION_MAJOR == 57) && (LIBAVCODEC_VERSION_MINOR > 48)) || \
    ((LIBAVCODEC_VERSION_MAJOR == 57) && (LIBAVCODEC_VERSION_MINOR == 48) && (LIBAVCODEC_VERSION_MICRO >= 101))

And problem solved...

Hi, sorry for reviving the topic.
But I didn't understand, well how does adding this dependency solve the problem?

I use Disto base Manjaro and the ffmpeg I have installed is 4.

By the way thanks, I added the dependency and it compiled I used version 27 the last one, because my laptop is old and doesn't have any necessary instructions for version 28.
