ffmpegdecklink -- Ubuntu 20.04 #335

Closed camardo closed 1 year ago

camardo commented 1 year ago

Upon installing ffmpegdecklink, libiec61883 does not appear to be installing with ffmpeg 5.1.2.

privatezero commented 1 year ago

Did you apply the flag when you ran brew install? brew install ffmpegdecklink --with-iec61883.

It won't install it automatically otherwise. You will also need to have the dependencies for the iec61883 device installed, which should be all or some of

sudo apt-get install libiec61883-dev
sudo apt-get install libraw1394-dev
sudo apt-get install libavc1394-dev
sudo apt-get install libavc1394-tools

See the vrecord linux install page for more information about the process and potential issues

Thanks @privatezero. I'm working with @ncam610 on this issue. We were missing the flag, and I ran through installing all the dependencies. Now when I attempt to install with iec61883, I get the following error message.

If you think configure made a mistake, make sure you are using the latest
version from Git.  If the latest version fails, report the problem to the
ffmpeg-user@ffmpeg.org mailing list or IRC #ffmpeg on irc.libera.chat.
Include the log file "ffbuild/config.log" produced by configure as this will help
solve the problem.

@privatezero -- I was confused about that. I was previously running ffmpeg 4.2.7 with -libiec61883 enabled. I received an error about updating ffmpeg to avoid potential a/v sync issues. I was having trouble installing ffmpeg 5 with iec61883, so I turned to the amiaos repo. It looks like there is a flag in ffmpegdecklink to enable libiec61883 if OS = linux:

@belak1 @ncam610 : Have you done

sudo apt-get install libiec61883-dev

as mentioned in Steps for a successful install of Vrecord on Linux?

privatezero commented 1 year ago

@belak1 I uninstalled ffmpegdecklink on my Ubuntu 20.04 machine, and was able to recreate your problem. It doesn't appear to be an issue on Ubuntu 22.04...@retokromer, are you aware of any changes that might have affected where Homebrew searches for dependencies on 20.04?

retokromer commented 1 year ago

@privatezero Off the top of my head, no. I am currently in Jerusalem and will be traveling to The Hague in a few days, therefore I cannot check it right now. I am sorry for that.

privatezero commented 1 year ago

@belak1 @ncam610, is this still an issue on your end? I've just retested on the same machine that reproduced the problem, and after a brew upgrade I was now able to successfully build ffmpegdecklink with the usual brew command. Possibly something upstream was worked out?

retokromer commented 1 year ago

@privatezero I am not aware of an upstream change, but it works on my end as well (with a little different setting though).

DabeDotCom commented 1 year ago

For whomevr this helps...

I managed to work around this by linking the system-installed libiec61883 and lib*1394 headers and libraries into a place the brew-installed gcc-12 could find them:

eval $(/home/linuxbrew/.linuxbrew/bin/brew shellenv) \
  && ln -sf /usr/include/libiec61883 "$(brew --prefix)/include/" \
  && ln -sf /usr/include/libraw1394  "$(brew --prefix)/include/" \
  && ln -sf /usr/include/libavc1394  "$(brew --prefix)/include/" \
  && ln -sf /usr/lib/x86_64-linux-gnu/libiec61883* "$(brew --prefix)/lib/" \
  && ln -sf /usr/lib/x86_64-linux-gnu/libraw1394*  "$(brew --prefix)/lib/" \
  && ln -sf /usr/lib/x86_64-linux-gnu/libavc1394*  "$(brew --prefix)/lib/" \ 
  && ln -sf /usr/lib/x86_64-linux-gnu/librom1394*  "$(brew --prefix)/lib/"

After that, brew install ffmpegdecklink --with-iec61883 applied cleanly.

Thanks much for reporting that @DabeDotCom!

Thanks! Troubleshooting updated in https://github.com/amiaopensource/homebrew-amiaos/pull/342
