Having some problems with the audio getting out of sync when watching Live TV. Anyone else having any problems like that? Playback of recordings seems to be working fine, just Live TV that is doing weird stuff.
I'm running AreaScout's XBMC branch with the latest version of FFmpeg and a patch for LATM AAC audio decoding.
BTW: the patch for being able to group recordings by title is very handy!
For anyone using XBMC with MythTV recorded DVB-T H264 content, you may need to use the <skiploopfilter> setting in advancedsettings.xml to get playback without the audio getting out of sync.
I was having audio sync problems with 1080i content with LATM AAC audio. AAC is quite CPU intensive (or so I'm told) and my AMD X2 6000+ CPU wasn't quite cutting the mustard combined with the also CPU intensive H264 video content. So, unless you've got a rocketship CPU that's faster than 3.0Ghz try adding <skiploopfilter>48</skiploopfilter> to the advancedsettings.xml file in userdata.
Valid values are -16, 0, 8, 16, 32, 48.
Basically the larger the number the more h264 content gets thrown out in an effort to save on CPU cycles. I just managed to get audio to play in sync at 32. xbmc.bin was hovering just above 100% with that setting.
