Bug 619486 – media-plugins/alsa-plugins-1.1.4: Building against media-video/libav-12 fails with "undefined reference to `av_resample_close'"

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Peter Levine 2017-05-23 23:43:29 UTC]

"alsa-plugins-1.0.28-libav10.patch" was dropped from alsa-plugins-1.1.4.ebuild, presumably because it doesn't apply cleanly.  This causes build failure when built with USE="ffmpeg libav":

Same here on ~amd64.

[Comment 3 Steve Arnold 2017-08-20 23:11:12 UTC]

Please try 1.1.4-r1 (it all works for me with the fixes in bug #621172 and a fixed "fix" for bug #588482 even with gold linker).

[Comment 4 Nathan Caldwell 2017-08-21 06:24:19 UTC]

Still failing here with 1.1.4-r1.

It seems all that -r1 changed was to depend on virtual/jack instead of directly on jack-audio-connection-kit.

ping.

[Comment 6 Peter Levine 2018-07-11 03:45:14 UTC]

There is no change in the incompatibility between alsa-plugins and libav (tested with media-plugins/alsa-plugins-1.1.6 and media-video/libav versions 12.2, 13_pre20171219, and 9999).  I switched to media-video/ffmpeg a while back anyway though. Since upstream is indifferent to the issue and it's unreasonable to maintain a patch with each version bump, perhaps the "libav" USE flag should be dropped and media-plugins/alsa-plugins should depend directly on media-video/ffmpeg.

See bug 653742.

Yep. media-plugins/alsa-plugins-1.1.7 builds fine. Tested against media-video/libav-12.3.

[Comment 9 Pacho Ramos 2019-06-30 10:52:52 UTC]

fixed in newer versions
