Bug#741935: Is the avbin package still being maintained?
Wow, until now I didn't even know there was a Debian package for avbin. I've been the maintainer since I picked up the abandoned project in 2011. Let me answer the questions in this thread in chronological order: I'm wondering if this package is still actively maintained? Not really at the moment. I would like it to be maintained...read on for the messy details. But maybe on linux they're fine? No, there is a problem with the fundamental changes in ffmpeg (before it forked libav and we switched to it) that occurred after the project was abandoned but before I tried to rescue it. The core symptom is visual artifacts and audio/video syncing issues with video. I spent a couple hundred hours researching and experimenting (and made all sorts of _other_ improvements to the project [web site, build system, binary installers]) but simply don't have enough C knowledge to figure this out...yet. I thought I had it figured out a dozen times. In fact, I *might* correctly understand the underlying problem, but all my attempts to refactor the thin wrapper to address the problem resulted in equivalent or worse behavior. I'm not certain if I misunderstood the problem, made an error refactoring avbin in the C code, or made an error refactoring Pyglet in the integrate-with-avbin Python/C code, or some combination of the above. (I did fix a lot of other issues along the way though...) The even bigger problem is that I stopped using avbin (and Pyglet) myself in 2013, so even though I could probably brute-force my way through figuring the problem out in another couple hundred hours...I don't _want_ to spend another couple hundred hours on it. If someone with a lot of C and/or Libav experience could lend a hand in fixing the dang core bug, I would be willing to fix the build system (at least on OS X, Apple manages to break compilation every dang release - the Linux/Windows builds may still work) and put out new binary installers. I may actually just fix the build system and issue a version 11 anyway, as Juan Martinez requested. Audio decoding was working well when I left off almost exactly a year ago. I took a brief look at it. It seems that the new upstream doesn't believe in a system provided libav... Well, ya. The entire point of the project is to supply a 1) self-contained, statically-linked, 2) 100% consistent (as in acts exactly the same way on any distro) portable (across distros) binary library whose ABI doesn't change 3) with an LGPL license (Libav needs to be configured a specific way for it to be LGPL instead of GPL). In a nutshell, the point of the project is to provide a single binary library for all the platforms Pyglet supports so Pyglet can use it to decode audio and video. I'm not sure that goal fits very well with Debian's packaging system. I'm surprised it got in the system in the first place, quite frankly. Maybe one of the four pyglet maintainers are interested in adopting it? If not, I'd still rather see it removed, at least from testing for now. I've offered to the pyglet community to transfer maintainership to anyone willing to take on the responsibility. So far no one has come forward. The offer still stands. I'd also be happy to stay on in a merge-contributed-patches and make-the-installers role. I'm just not willing/capable to do the research/refactoring necessary to fix the outstanding core issue in the C code. I don't have any opinion one way or the other as to whether avbin remains in the Debian package system. If you decide you want the binary version that we build, I'm willing to follow whatever QA steps you have for the packaging system. If you decide that it doesn't belong in the Debian packaging system, that's okay with me too. If you really want a build-it-from-source-on-debian version, then someone else will need to step up and do the work. --- Now that Libav seems to have stabilized on versioned branches, another option is for Pyglet to refactor its avbin python module to integrate with libav directly on the various systems. Then there would be no need for the avbin project at all, and we could simply close down the project. As far as I am aware, no project other than Pyglet uses avbin. (Though many projects use Pyglet). ~ Nathan
Bug#741935: Is the avbin package still being maintained?
Hi, I'm Juan J. Martinez, one of the maintainers of pyglet upstream. I found this bug report and I'd like to add some information in case it helps. AVBin is technically optional for Pyglet, but in practice is a requirement as pyglet can only handle a very limited set of basic media formats and AVBin is required for anything else. Re: https://github.com/AVbin/AVbin/issues/41#issuecomment-10700404 AFAIK there are some issues with video support that are a blocker to get AVBin 11 out; but audio support is stable. Re: AVBin forking libav: AVbin is designed to be used with a particular version of Libav. This version of Libav is included as a git submodule of the AVbin project under the libav directory. Note that this version of Libav may contain AVbin-specific patches, though we try to get all patches accepted upstream. When AVBin started libav was in continuous development and it was changing the API too often making difficult to track. Looks like the situation has changed and perhaps AVBin maintainer would be keen to start tracking one release branch of libav. I've contacted current AVBin maintainer upstream trying to get help from him regarding this issue.

Bug#741935: Is the avbin package still being maintained?
Package: avbin Severity: serious Hi, I'm wondering if this package is still actively maintained? I cannot help but noticing that the debian avbin package lacks several upstream versions behind, and has seen its latest maintainer upload almost 5 years ago. If the current maintainers think it would be best to let this package go, then I'd suggest to reassign this bug against ftp.debian.org and ask for its removal. Otherwise, I'd suggest to close this bug by uploading a new upstream version (and consider orphaning this package). In any case, I'd suggest to remove avbin from testing for the time being to not hold up the libav10 transition further, which is file I file this bug with severity serious. -- regards, Reinhard -- To UNSUBSCRIBE, email to debian-bugs-rc-requ...@lists.debian.org with a subject of unsubscribe.
