#1704 Add support for ffmpeg 5.x

[Frederic bezies]

Hello.

In the coming months, main distributions will push ffmpeg 5.x either in their testing or main branch.

I tried to build Vice with ffmpeg 5.0, and I got this error in configure stage:

checking for FFMPEG_AV... yes
checking for libavformat/avformat.h... yes
checking for FFMPEG_SWSCALE... yes
checking for FFMPEG_SWRESAMPLE... yes
configure: error: ffmpeg version is not comnpatible. Use 4.x

Workaround? Remove --enable-external-ffmpeg to continue build process.

A proper support - if possible - of ffmpeg 5.x will be great!

This is not a bug. FFMPEG has been a constant annoyance due to their API breakage and thus will be removed.
That said, it will likely take a while before ffmpeg 4 will no more available in distros

OK. Can you add an ffmpeg 4.4 detection in configure step? On my test, I'm stuck because configure only found ffmpeg 5.x even if I have both ffmpeg4.4 and 5.x installed.

Thanks!

Edit: Archlinux - which I'm using - is now providing both ffmpeg 5.0 and 4.4. I have to remove --enable-external-ffmpeg to get build process working again.

So I cannot record any video until there is a working detection for ffmpeg 4.4 :(

please attach your configure.log

Here it is. If you need files from ffmpeg4.4 package, you can find these here: https://archlinux.org/packages/extra/x86_64/ffmpeg4.4/

I think I found a workaround (based on a tweak applied to Dosbox-x-sdl2).

If I use this configure line, ffmpeg 4.4 is added to produced binaries.

PKG_CONFIG_PATH="/usr/lib/ffmpeg4.4/pkgconfig" ./configure --prefix=/usr --libdir=/usr/lib --enable-external-ffmpeg
