Liquidsoap 2.2.0 install problem with OPAM

[SkillenUK]

I'd be grateful if someone could offer some advice. I'm trying to install Liquidsoap 2.2.0 with OPAM, but ffmpeg-avcodec.1.1.8 fails to install. I'm running...

opam depext taglib mad lame cry ffmpeg ssl liquidsoap
opam install taglib mad lame cry ffmpeg ssl liquidsoap

During the install I see the message...

[ERROR] The compilation of ffmpeg-avcodec.1.1.8 failed at "dune build -p ffmpeg-avcodec -j 1 @install".

If I try to then try to install ffmpeg-avcodec.1.1.8 seperately I get...

Requested 'libavcodec >= 58.87.100' but version of libavcodec is 58.54.100

I'm a bit stuck as to what I need to try now. I started with an OPAM switch for ocaml 5.0.0, so it was a clean start rather than an upgrade from Liquidsoap 2.1.4. I know that the build method has changed so I have posted in discussion because I suspect it's something that I'm doing wrong rather than an issue.

Thanks,

SkillenUK.

Hi @SkillenUK,

• liquidsoap=2.2.0 requires ffmpeg=1.1.8
• ffmpeg=1.1.8 requires libavcodec>=58.87.100
• ubuntu:20.04 provides 58.54.100

If I were you, I would consider one of these options

1. Use liquidsoap in a container.
2. Upgrade ubuntu to 22.04.
3. Install ffmpeg from ppa, for example https://launchpad.net/~savoury1.
4. Build ffmpeg from sources.

Thanks, it might be time to move to Ubuntu 22.04 :)
