For those wondering: I intentionally keep this package as close to the native package as possible, to the extent of the available dependencies. FFMPEG package sees a lot of modifications through time and I prefer to follow the changes applied to the native PKGBUILD as much as possible. The more it goes, the more flags are added and the more often we need to cherrypick commits (until a new release comes in).

This means I'll keep the dependencies around even if there is no obvious usecase for them.

Also, since openjpeg2 is still used with the native package, I'll also keep it around. Last thing I read about the JPEG2000 internal decoder was that it was faster, but that it was still introducing errors in the rendering. This probably explains why it is still enable in the native package. I look at it once in a while and things may have evolved since, but a quick checkup didn't bring up any tangible answer.

Now, if someone would like to take the ownership of this package, I would be more than pleased to hand it over. The same goes for any related packages that I maintain mostly for FFMPEG. lib32-libffmpeg and lib32-ffmpeg could be merged back together to simplify its maintenance.

Let me know if this is something you're interested in.

About GPG, it is up to you to import the missing public key. If you receive an error about it, this is ffmpeg's project public key. Something like the following should do the trick: gpg --recv-keys B4322F04D67658D8

@oxalin Have you taken a look at DistroWatch's RSS feed? They usually post an update to ffmpeg although I am not sure if it's possible to filter out notifications...

slyscorpion commented on 2017-01-08 06:04 (UTC)

@oxalin Thanks for the tip on the keys :)

@slyscorpion: it is up to you to import the missing public key. This is ffmpeg's project public key. Something like the following should do the trick: gpg --keyserver x-hkp://pool.sks-keyservers.net --recv-keys B4322F04D67658D8 On another subject, I'm updating the package to 3.2.2. I still need to figure out a way to be notified from new releases automatically. The ffmpeg's RSS is unreliable.

This package fails to build due to PGP signature issues: ==> Validating source files with sha256sums... ffmpeg-3.2.1.tar.bz2 ... Passed ffmpeg-3.2.1.tar.bz2.asc ...

Thanks JonnyJD. Patch was first included, and then removed since the dev group released 3.1.5 which already includes the openjpeg2 patch. Sorry for the noise. To be noted: SDL support will be dropped in the next release in favor of SDL2. Stay tuned.

Sorry, I don't have time to maintain the package, currently. I made oxalin the new maintainer (the notification mail is wrong, I disowned).

@versusvoid It could be added, but that would be up to @JonnyJD to do.

@oxalin Adding lib32-openjpeg2 to `depends` also wouldn't be a bad thing.

@Enverex, there is another (new) known bug about undefinded references to openjpegenc.o after a recent change in the static openjpeg2 library... Briefly, it comes to "The FFmpeg code was setting OPJ_STATIC, and in master, OPJ_STATIC sets API method visibility to hidden (because it is a static build, so visibility not needed)." See https://trac.ffmpeg.org/ticket/5694 The next ffmpeg release should contain the following fix: https://trac.ffmpeg.org/raw-attachment/ticket/5694/ffmpeg_opj2.patch @JonnyJD Meanwhile, maybe we would be better to add and apply that patch to the current package.

@JonnyJD - Just an FYI, installing lib32-openjpeg2 doesn't fix lib32-ffmpeg failing to build (with the /usr/bin/ld: libavcodec/libavcodec.so.57: hidden symbol `opj_setup_decoder' isn't defined error). Removing openjpeg2 is the only way to have the build complete (doing an -Rdd then reinstalling it after this is built seems to be the easiest way to get around it).
