LAV Filters - DirectShow Media Splitter and Decoders

+1 I can confirm if you want full bit rate and depth then TMT3 .185 is the way to go (I also own both)

Thanks for looking into the LATM issue.

Actually, both hearing impaired DVB subtitles (The Gift sample) and visual impaired audio tracks (Star Wars sample) in MPEG-TS are now tagged correctly running a recent ffprobe.exe. I guess that means this patch, or at least part of it may no longer be needed, if you're still applying it?

I actually got that applied upstream.

Nice.

I found the offending commit that broke LATM decoding. I'll revert it and upload a new 0.19 zip with a fixed ffmpeg. I will also try to bring it up with the ffmpeg devs, but from past experience, responding to regressions on old commits never really worked too well..

[nevcairiel]

Ok, same URLs as before

Download: 32-bit & 64-bit

Just that one commit reverted. I'll do a full update on ffmpeg tomorrow, and see if its maybe fixed (doubt it, from skimming the commit list since then), and try to get some attention on the mailing list, somehow. For some reason getting some change commited just by saying it works is easy, reporting a bug requires more then saying "it doesn't work". <.<

Please confirm that the issue is indeed fixed for you as well.

[Ger]

Yes, I can confirm it's fixed for me as well with avcodec-52.dll dated 20.03.2011 01:25.

I'll try to fix the libavcodec mode.

Here is hoping this is what was causing my MPEG-2 Seek Crashes with LAVSplitter. Changed from libmpeg2 to libavcodec and all so far (fingers crossed) is good!

[nevcairiel]

That old problem, eh. I still blame ffdshow for the crash, not sure why it doesn't happen with any other splitter, but it also doesn't happen with any other decoder, including the MPC-HC decoder which also uses libmpeg2.

Personally, i like the MS DTV Decoder for MPEG-2 content.

[jmone]

Yeah no idea either..... Anyway, I'm trying to keep the number of Filters down to a minimum and FFDSHOW's Subs and deinterlacing (YADIF Double Frame rate) is pretty good IMHO. So for me the ideal set of filters is looking like:
- LAVSplitter
- LAVAudio for all but DTS + Arcsoft HD Audio for DTS (thanks again for this config option!)
- FFDSHOW for Video (ffmpeg-mt for 264/AVC as handles 50p content without stuttering, libavocdec for the rest) + "MS WMVideo Deocder DMO" for VC-1 as it handles Interlaced VC-1 well (mmm I have not tried the Arcsoft decoder.....)
- madVR for the Video Renderer
- Reclock for the Audio Renderer (at least until J.River add auto frame rate changing to their renderer which should be soonish)

ffdshow? MS DTV Decoder? Are you guys watching that much native video content? If not, I wonder how you could *not* use the DScaler5 IVTC Mod MPEG2 decoder.

[nevcairiel]

I don't really watch any interlaced or TC'ed content, but if i do (got some DVDs that are TC'ed), i usually prefer hardware deinterlacing/ivtc, never got any software work as smooth as that (even when that means not using madVR for that few DVDs)

I cannot get Dscalar (with updated dlls) to work on Win7 x64 with any player. What OS are you using?

Are that PAL or NTSC DVDs? AFAIK, for NTSC movies hardware IVTC gives you 30p or 60p for movie content, which will result in the typical 3:2 motion judder. The DScaler IVTC mod should give you perfect 24p output instead. For PAL content the situation is different, though.

Works just fine on my win7 x64 HTPC. Anyway, this is out of topic, I guess. Was just wondering why you guys didn't use the DScaler IVTC mod.

NTSC. From what i experienced, if you use DXVA decoding and do IVTC in the same step, it actually reduces it to 24p properly.

In any case, can't use madVR for DVDs anyway. Screw you macrovision

Weird. Looking at the DXVA deinterlacing APIs, I don't see how that works. Anyway...

Now that madVR is working with the MPC-HC internal sub renderer (thanks Madshi ), I started playing around with it.

I noticed that LAVS does not work with the MPC-HC keyboard shortcut for switching streams ("S" and "Shift+S" are default, I believe).

Is this something that can be added?

Sweet. Can't wait to try it when I get home tuesday!

Hi.

I am posting this problem here too, becouse i would like to found the source of this issue - i just tested LAVF v.19 audio decoder + splitter.

DTS + EVR custom renderer = stuttering

I noticed there is a stuttering/droped frames in videos with DTS track if custom EVR renderer is in use (like MPC-HC/MediaPortal one). If i use simple EVR/VMR9 - no problem.
It can be fixed by disabling jitter correction (in fffshow).

Here is a video sample. (more info).

I have this problem in nearly all videos with DTS audio.
