With the same configure-options, ffmpeg could also be shipped as singel package.
I asked about it here

Yes, but then anyone who wanted to build their own ffmpeg with additional options would end up having to rebuild all the stuff that links with it (the ffmpeg api/abi has a habit of changing frequently). I use ffmpeg and mpv, and I'm glad I can add those to my system without breaking other parts that I would have to rebuild if a system level ffmpeg library were used.

This is only the case if another ffmpeg-version is used, you could stick with that ffmpeg that would come as stock package, adding options without further player-recompilation. If you really need a bleeding edge ffmpeg, than you'll have to recompile your player against ffmpeg anyway to be able to playback the files.

MPlayer/Xine could break, of what interest are these if one uses mpv?
If Mplayer/Xine are really wanted with the limited ffmpeg(thats the current case), you could build them statically with ffmpeg. I think most people would be happier with adding codecs to alle players using a stock ffmpeg.

Maybe there are multiple users on the system that prefer to use different players, or perhaps the choice is dependent on the media being played: Xine is still better at DVD menu's than the others, which is what I use it for.

Yes, I could rebuild everything impacted if necessary. I was merely pointing out that the static/in-tree builds simply mean that I don't have to (admittedly at the cost of them becoming 'stale' over time).

On my flash-drive with Alien's Live-Slak (the latest Plasma), this is what I got when trying to build it...

Code:

root@darkstar:/home/live/built_srcs/libvorbis (aoTuV enhanced)# ls
aotuv_for_1.3.5.diff    libvorbis-aotuv_b6.03_2015.tar.bz2  slack-desc
libvorbis-1.3.5.tar.xz  libvorbis.SlackBuild*
root@darkstar:/home/live/built_srcs/libvorbis (aoTuV enhanced)# ./libvorbis.SlackBuild
tar: /home/live/built_srcs/libvorbis: Cannot open: No such file or directory
tar: Error is not recoverable: exiting now

@ftio Hmmm.... can't reproduce this. I have altered the slackbuild a little to avoid picking up the wrong archive in the build folder but this should have no bearing on what is happening on your system...

rename the folder where you are building from without spaces.

That was the ticket! Thank you, ponce!

Giving this old thread a boot with an updated version, this time with aotuv and lancer:

http://www.andrews-corner.org/slackb..._aotuv_lancer/

Remember that this replaces the stock libvorbis that comes with -current. Test run here demonstrates typically:

Code:

andrew@ilium~/tmp$ ogginfo "02. Canzonetta , Allegro vivacissimo.ogg"
Processing file "02. Canzonetta , Allegro vivacissimo.ogg"...

New logical stream (#1, serial: 6a4579fe): type vorbis
Vorbis headers parsed for stream 1, information follows...

And with both a nice sound and a fast encode....
