Bug 678222 – media-tv/kodi-17.3-r1 with media-video/ffmpeg-3.4.5 - sound output issues

• Status: RESOLVED FIXED
• Product: Gentoo Linux

[Description Sebastian 2019-02-17 10:31:38 UTC]

Hi all,

Yesterday ffmpeg was upgraded from 3.3.6 to 3.4.5. Afterwards I noticed that the sound was not working in kodi. The sound just was bad. Lots of noise (seemingly unrelated to the codec - I tried mp2, ac3 and dts, they were all sounding way off).

I found a Debian bug report about the same, see URL above. It includes a small patch to fix this. Alpine uses the same (https://raw.githubusercontent.com/alpinelinux/aports/master/community/kodi/19-fix-audio-with-latest-ffmpeg.patch).

I'm using stable kodi 17.3. With the patch applied the sound is back to normal.

Kind regards,
Seb

Reproducible: Always

Video is also a bit off. When skipping the video goes green for a few seconds. This was already reported elswhere and fixed upstream (https://github.com/xbmc/xbmc/pull/12988).

The patches that Debian uses are here: https://sources.debian.org/src/kodi/2:17.6+dfsg1-4/debian/patches/

c7e2acc1b2ee781af6e14d80da0edd0aa23bdf03.patch

They apply cleanly to 17.3. The green screens after skipping are gone.

Regards,
Seb

Can you please test again with media-tv/kodi-17.6-r10 which I just added? I included the referenced patches - please let me know if it fixes the issues. If it does, I'll request that version to go stable.

And thanks for reporting the issue!

Hello Craig,

When trying to "emerge" media-tv/kodi-17.6-r10 it wanted to downgrade ffmpeg to 3.3.6. media-tv/kodi-17.3-r1 didn't do that and then it'd be pointless to add the patches. I suppose that was not your intention :-)

I removed the "<media-video/ffmpeg-3.4" line from

  system-ffmpeg? (
    >=media-video/ffmpeg-${FFMPEG_VERSION}:=[encode,openssl,postproc]
    <media-video/ffmpeg-3.4
  )

and built against 3.4.5. And indeed it all works fine.

Thanks!

Best regards,
Seb

Great - I'm adding -r11 with this change.

I'll file a stabilization request on March 18 (one month from now).

[Comment 6 Ewoud Kohl van Wijngaarden 2019-03-12 21:38:22 UTC]

Can confirm 17.6-r11 fixes my issues.

[Comment 7 Craig Andrews 2019-03-28 14:57:56 UTC]

Resolved by -r11 stabilization, see bug 680852
