Bug#593162: marked as done (audacity: Audacity fails to load libavformat)
Attached patch allows audacity to runtime detect match_ext() vs av_match_ext().
Audacity compiled with this patch against FFmpeg 0.5 will still have
problems with AVPacket and AVFifo API issues that they have put behind

Bug#593162: marked as done (audacity: Audacity fails to load libavformat)
Well, for exactly reasons like this, I find installing libraries from 3rd party repositories problematic at least. I agree it's not ideal, but unfortunately there's some functionality that isn't present in the main repositories. (for example, a build of gtkpod that supports AAC) And I've asked you to check this. Until this happens, I'd agree to leave this bug closed. It would be great if you could help with filling the gaps. Since that's the case, I can try both the testing and experimental versions, but most likely it will be this weekend or the next when I have the time.

This thread on Audacity forums ( http://forum.audacityteam.org/viewtopic.php?f=18t=28048) documents the problem, and also includes a patch. According to that thread, the change appeared in ffmpeg 0.5.1. If I'm reading the version numbers correctly, both debian-multimedia and experimental have ffmpeg 0.6 (with slightly newer version in debian-multimedia), the package distributed by debian-multimedia is not based on ffmpeg 0.6, it is just horribly and confusingly named. It is based on SVN trunk, were a lot of development is going on, and such compatibility bugs still need to be found and ironed out. Christian Marillat is obviously not helping with that at all. and the standard squeeze install has 0.5.1. (which also means that the standard squeeze libraries might experience the same problem) And I've asked you to check this. Until this happens, I'd agree to leave this bug closed. I would prefer not to try to install a different version of the libraries since I don't have any experience working with different repositories like that, especially since I would have to deal with the dependencies. Well, for exactly reasons like this, I find installing libraries from 3rd party repositories problematic at least. (I'm mainly worried about getting everything back together again when I'm done...) If somebody could try it on a standard testing and/or experimental install that would be great. Well, you've reported an imcomplete bug, and I've told you what information is missing. It would be great if you could help with filling the gaps. -- Gruesse/greetings, Reinhard Tartler, KeyID 945348A4 ___ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/pkg-multimedia-maintainers

I'm actually pretty confident that this problem also appears with the ffmpeg package from experimental. Aaron, or someone else, can you please try to reproduce this with the package from experimental? If I'm right, then this bug needs to be reopened. Aaron's analysis about the match_ext vs. av_match symbol makes totally sense to me. audacity shouldn't have used the match_ext function from libavcodec at the time it was still private at all. -- Gruesse/greetings, Reinhard Tartler, KeyID 945348A4 ___ pkg-multimedia-maintainers mailing list pkg-multimedia-maintainers@lists.alioth.debian.org http://lists.alioth.debian.org/mailman/listinfo/pkg-multimedia-maintainers
