I'm compiling with msvc and get some errors with PRIx64 and similars.
For example:
snprintf(name, sizeof(name), "0x%"PRIx64, ch_layout);
won't compile, but this work (with the extra space):
snprintf(name, sizeof(name), "0x%" PRIx64, ch_layout);
Can this be included in the sources without introducing problems for
other platforms?
You'll have to provide more information. We have automated builds with
MSVC which are running just fine right now.

For example, in ffplay.c sample (ffmpeg version 5.0.2):
if (is->audio_filter_src.channel_layout)
snprintf(asrc_args + ret, sizeof(asrc_args) - ret,
":channel_layout=0x%"PRIx64,
is->audio_filter_src.channel_layout);
gives the following error:
error C3688: invalid literal suffix 'PRIx64'; literal operator or
literal operator template 'operator ""PRIx64' not found
The error is gone when adding a space before PRIx64.
Note that I'm mixing C and C++ in my projet. Compiling in plain C seems
to work.
