Since i use my own splitter and decoder, and i have never seen such issues, i'll just say "cannot reproduce" :d

I've always had jitter correction enabled in ffdshow, and i never noticed the problem. I also never saw the problem with my own decoder.
Sounds like something else, possibly a audio renderer thing thats just being triggered by that.

Never dropped frames, except on some very weird movies i get one or two on load, but none in playback. Jitter is most of the time 0, sometimes (rarely) a value something below 10, but nothing that i ever noticed in playback (including the EVR-CP OSD graphs, perfectly smooth)
Oh, and do me a favor and shrink screenshots :P

Remove DTS track from MKV = no stutter. It happend only on DTS + custom EVR. Again, if i use simple EVR, playback is perfect:

Maybe you should bring that up with the renderer devs, then.. :d
As i said, i sometimes do see jitter with values < 10, but never dropped frames, and never any visual problems with the video.

For example MePo dev wrote that this is audio decoder bug. I just trying to found the source of this issue :/ Only way i found how to fix it is to use ffdshow audio decoder with disabled jitter correction.

Does it happen with other splitters?
You already said it happened with ffdshow as well, but only with LAV Splitter?

Only one thing helped - disabling jitter corection in ffdshow audio decoder - stuttering and droped frames are gone.

@nevcairiel:

I don't really have any active jitter correction in the LAV Audio Decoder .. i can produce a test build to disable on thing and see, but i don't think its relevant, but hey testing may help

I'll have to run some tests if that has negative results for other files, but in theory it should not have.
Thinking about it, i'm not sure why i coded it like that. If someone else wants, i would appreciate some tests using the version linked with various audio codecs, if you notice any problems. Just to be sure you see it, here is the link again: http://files.1f0.de/lavf/LAVFilters-...itter-test.zip

Running the jitter test ax now. Not noticed anything different so far, but I didn't have hoborg's problem in the first place.
On a different note, am I missing something regarding the new AC3 sub stream in TrueHD option? I've been testing the Dolby TrueHD Channel Check and another TrueHD sample from here, and I can hear the audio when the truehd 7.1 track is selected, and an AC3 5.1 track is exposed and tagged as [sub], but if I select that AC3 track I hear only silence. The LAV Audio status page shows constant full/maxed out bars on all 6 channels and 16-bit int under decode. 32-bit float output, channel mask looks right, 0x3f as with other AC3 5.1 tracks. Channels, sample rate, codec also looks OK in that status page. Everything seems normal when the "normal" truehd track is selected. |

The substreams are not new, what is new is the option to hide them. Previously, i would just always show them.
Can you possibly try 0.18 and see if it works there? I might have an idea what could potential have broken it, but i cannot test right now.
