mpeg4ip activation fails

[yanjingfeng@…]

After the installation of faac (audio), there will be activation fault when installing mpeg4ip. The error claims mp4.h is used by faac and needs to deactivate faac to finish mpeg4ip installation. A possible solution is change mpeg4ip include and lib directory.

As of 9/28/2007 version 1.6.1 was released and all upstream development was abandoned. Current MacPorts version is 1.5.0.1. Is there any interest in updating this port and addressing the issue of this ticket or should this ticket be closed and the port possibly deleted from MacPorts. Isn't this functionality available in other ports?

[dbevans (David B. Evans)]

Actually their download page ​http://mpeg4ip.sourceforge.net/downloads/index.php says the current tar ball is corrupt and they can't regenerate it. I vote to delete the port.

Replying to devans@…:

I agree, however, aacgain appears to depend on it currently, so that will have to be updated to use an alternative if possible. Cc'ing aacgain's maintainer.

[dbevans (David B. Evans)]

The following ports also have variants that depend on mpeg4ip:

cmus +aac
easytag +mp4
easytag-devel +mp4

Cc'ing their maintainers as well.

[dbevans (David B. Evans)]

Referring to the homepages for aacgain, cmus and easytag all claim to be dependent now on libmp4v2, a subset of the functionality of mpeg4ip which avoids potential patent problems with the full mpeg4ip. It is available here: ​http://resare.com/libmp4v2. However, it appears that port faac comes with libmp4v2 embedded which is the reason for the conflict.

It looks possible that the solution is to get rid of port mpeg4ip and have the ports that currently depend upon it depend upon faac instead.

I'm going to try this with easytag which currently has no maintainer and see if this works.

[dbevans (David B. Evans)]

Well, faac doesn't work to replace mpeg4ip. Although both have versions of libmp4v2, the separate libmp4v2 distribution has additional functions that easytag and others need. But faac can be configured with a --without-mp4v2 switch in which case it builds fine against libmp4v2 (or mpeg4ip).

Since libmp4v2 is reputed to be free of mpeg4ip's patent infringement issues, I suggest that it be used as a replacement for mpeg4ip and then build faac with the --without-mp4v2 option to avoid a conflict.

Have created a new port libmp4v2 (committed in r41643) and updated easytag (committed in r41643) with good results. If faac and the others can be modified to use libmp4v2 (which is what they now seem to prefer) then mpeg4ip can be deleted.

[dbevans (David B. Evans)]

Oops, easytag was committed in r41644.

[dbevans (David B. Evans)]

Modifications to faac to depend on external libmp4v2 committed in r42233 (#17141).

[dbevans (David B. Evans)]

cmus variant +aac changed to depend on libmp4v2 in r42285. easytag-devel variant +mp4 changed to depend on libmp4v2 in r42974 (#17297) aacgain changed to depend on libmp4v2 in r42956 (#17298)

[dbevans (David B. Evans)]

A grep of the ports tree indicates that there are no remaining dependencies on mpeg4ip either directly or via variants. All such previous dependencies have been replaced by libmp4v2.

Is there any objection at this point to deleting port mpeg4ip for the reasons outlined above and closing this ticket?

[dbevans (David B. Evans)]

Port mpeg4ip deleted in r43479.

[dbevans (David B. Evans)]

Port mpeg4ip restored in r43903 less files provided by port libmp4v2 per request in #17651.
