mlt-0.5.6- build error

[julpub@…]

Hi, I am new to MacPort.

I have an issue building mlt. I do not understand the log. I have pass the ffmpeg issue, activating ffmpeg-devel.
Any help would be appreciated. If I have to supply other details, let me know.

oups, Sorry. How to find the maintainer's email for a given port ?

ok, I have found how to know the maintainer, sorry again.

I think this should only happen if you have an old version of ffmpeg installed - perhaps one not from macports.

The MLT configure script uses the output of 'pkg-config --modversion libavcodec' to determine whether to use the old img_convert or the current swscale API. The img_convert API was removed in 2009, but I keep some old compatibility around for some commercial users. Run that command in a terminal and report the result here. It should be >= 52.21.0. If not, then you probably have more than one copy of ffmpeg installed on your system.

Hi,

I have executed "pkg-config --modversion libavcodec" command, it returns "52.66.0". Does it mean I have a too recent version ?

a "port installed" returns "ffmpeg-devel @22866_0 (active)" but no ffmpeg installed.

How can I know if I have another copy of ffmpeg installed ? May it comes from 3rd Party software that I have installed, out of MacPort scope ?

Thanks in advance

[dan@…]

52.66.0 is fine. That is what I am using too. So, it should be working regardless if there is another ffmpeg installed. Locating another installed ffmpeg can be a bit complicated - it basically amounts to searching your disks for some files. Let's skip that for now. I see something from your log that is a very reasonable explanation: ":debug:main Skipping completed org.macports.configure (mlt)"

Basically, the mlt package configure step was executed when just the 'ffmpeg' package was active instead of 'ffmpeg-devel' and on this build it is skipping build steps already completed. I think the -f option to the port command will take care of installing it by restarting the process (not all dependencies, just mlt): port -f install mlt

[dan@…]

forgive me; I am not a port expert. Now I am thinking if -f does not work, then perhaps a 'port clean mlt' will reset the state of that package.

[julpub@…]

doing the port -f does not succeed, but the clean does the work. I have it installed !

Thanks a lot for your help.

How do I update this libavcodec? I have 52.20.0 and want the most up to date one.

RTFM sudo port sync sudo port upgrade ffmpeg-devel
