[RPi] r12458 Audio - Delay in every MKV-File with AC3-Stream

[klopsknoedel]

Sound comes ~200ms to late in every MKV-file i've tested.

Here's a representative sample media info:

report to xbmc

Or you can try setting the latency in advancedsettings.xml

<advancedsettings>
  <video>
    <refresh>
      <min>23</min>
      <max>26</max>
      <delay>200</delay>
    </refresh>
  </video>
</advancedsettings>

latency is not working for me because other files without AC3 - Streams work as expected. May this correspond with Issue #1276

Edit: Could someone please add this report to "XBMC Upstream"?

[popcornmix]

Can you run: tvservice -d edid.dat edidparser edid.dat and post that here. (I'm interested if your tv/receiver reports a non-zero audio or video latency)

Unfortunately your TV/receiver is not indicating different audio/video latency: HDMI:EDID HDMI VSDB has no latency information

so there is nothing that can be done automatically there.

Do you have AC3 passthough enabled in xbmc settings?

[klopsknoedel]

Yes, passthrough for whole audio because I thought reencoding could cause latency.

[klopsknoedel]

Sorry, I accidently closed this issue.
