[PPA] libopencv-dev incompatible with format junkie dependencies

[Thomas Ward]

Refer to this for details:
http://askubuntu.com/questions/210500/error-while-installing-an-application/210537#comment261808_210537

Apparently, installing libopencv-dev causes formatjunkie and other libraries it depends on to be uninstalled.

[Thomas Ward (teward)]

Issue traced a bit:

Package: libavcodec-extra-53
...
Conflicts: libavcodec53

This package here, with -extra-53, is part of the libav-extra source package. The packages we're using in the PPA are dependent on the -extra-53, but whatever "extras" are included in that set of packages conflicts with the more minimal set of packages in the libav source package. I can't fix that. Can you guys build it with only the libav stuff, and not the -extra-53 and similar package libaries? If that works, I'll change the package to use only those minimal libraries.

alexsol: does FormatJunkie run with libavcodec53 and related packages (and not the -extra ones)? If so, I can resolve this with the next package update in the PPA, along with Bug #1073980. (the version will not change, but the package revision number will)

If that's not possible, then this becomes "Won't Fix" because its not going to be changed.

[Alex Solanos (hakermania)]

Too busy to check it right now. Please wait till (Sat/Sun)day :)

[Alex Solanos (hakermania)]

Format Junkie runs well as far as I tested it even with the libavcodec53 installed. Please build FJ only with this package, there shouldn't be any problems.

[Thomas Ward (teward)]

OK. I'll do this once I get my packaging system back from repairs. Set the status to Triaged here, please.

[Thomas Ward (teward)]

Fix Committed to the PPA builders, if the PPA doesn't update to that information in the next 20 minutes or so i'll reupload.

[Thomas Ward (teward)]

Marked "Fix Released" due to fixes being in the PPA.

Hi,

I'm the one who wrote an article about FormatJunkie in the french Linux Pratique Essentiel Nr 29 (http://www.ed-diamond.com/feuille_lpe29/index.html pages 80 & 81) and who told you about Bug #1070737 and Bug #1070746 (but I'll come back later on those two).

I'm sorry to tell you that, with changing the dependency between libavcodec-extra-53 to libavcodec53, you just remove the ability to convert an audio file to MP3 !!!!!!!!!!!!!!!
And by the way, made impossible to upgrade FormatJunkie without removing libavcodec-extra-53, the one that CAN convert to MP3...

I believe you when you're saying: "Format Junkie runs well as far as I tested it even with the libavcodec53 installed." but it seems you're not using MP3, what Joe average user and the people I try to get away from Windows will!!!

Some proofs of what I'm saying:
- try to convert any FLAC file to MP3 = you get "The conversion of 1 file has finished with one error!
- use the "Show Errors" to see the log and here it is = no MP3 encoder available !!!

log:

Solution:
As it's impossible to force aptitude or apt-get to work this dependency problem, you have to install FormatJunkie with the libavcodec53 package (and let him remove libavcodec-extra-53), then modify the /var/lib/dpkg/status file, changing the "Depends:" line back to "libavcodec-extra-53" (and NOT libavcodec53) and then, installing AGAIN libavcodec-extra-53, which will in turn removing libavcodec53 at the end.

And when you've done all this, you can AGAIN convert a file from FLAC to MP3.

But sadly, that brings us to the point that Bug #1070737 is STILL NOT solved, because with 100% quality, you STILL got an ugly 78 kbps audio file, where with 1% quality conversion, you got a nice 230 kbps...

And, if you try to convert the FLAC file to OGG, it still uses the FLAC codec (as in Bug #1070746) and not the Vorbis, making a .ogg file with the same size as a .flac, what doesn't relly make it a challenger to the MP3 format for newbies....

So, leon promised to solved the 2 other bugs, that didn't happened from October 'till now, but this one get "solved" in 3 weeks, breaking FormatJunkie a little bit more ? I'm not sure I would write the same article today...

Reopened as a [REGRESSION]

[Thomas Ward (teward)]

actually, ignore that on #10, replace with "Fix Released"

[Thomas Ward (teward)]

fvj (fred-alternation): please refer to LP Bug #1092524 for the regression bug. And for PPAs, please file new bugs when previous bugfixes break things, i don't like reopening older bugs unless I have to.

[fvj (fred-alternation)]

Thomas (teward): OK, will do if I find anyhting else in the future.
And THANKS a lot for the lightning fast reaction =:)

[Thomas Ward (teward)]

Reversing the change in which I set this as Won't Fix. just because this bug in its form was fixed, although it introduced the regression in Bug 1092524.
