I am trying to rebuild ffmpeg 4.2.2 with new dependencies.  Honestly, I
really don't know much about ffmpeg except that it probably should have
x264, aac, and other common libraries.  So, I try to enable everything,
based on the --current ffmpeg-4.2.2 slackbuild, with source from --current.

Using a sbopkg file,   libffado seems to fail.  Also, I thought it was a
dependency for jack, but it looks for jack at the beginning.

  MD5SUM check for libffado-2.4.1.tgz ... OK
  Error occurred with build.  Please check the log.

Would you like to continue processing the rest of the
queue or would you like to abort?  If this failed
package is a dependency of another package in the queue
then it may not make sense to continue.

(Y)es to continue, (N)o to abort, (R)etry the build?: N
