Hi Nev,
Haven't used LAV filters for watching DVB-T broadcasts for about a month, but today I tried and quickly noticed a regression in the LAV audio component of 0.37, comparing to 0.36.
In 0.36 the audio is decoded fine, while in 0.37 the audio is decoded with lots of "noise" on top.
Also happens with the following dump when playing it offline in MPC-HC.
Here is a sample of a raw mpeg-ts dump, captured via the DVB-T application.

I figured out what broke it, its a change in ffmpeg. I'll revert it for the time being, and let them know about the issue.

Thx for supporting vobsub in mp4 files. Hope for officially supporting ordered chapters.

Custom build ( 32 and 64 bit )
LAVFilters-git-r1365(2dc15e5).7z: MediaFire, NMM-Mirror

PS. Could you please add an option to prefer text formats subtitles or image formats when they are in the same language?

Can we expect to add a deband filter and a TIVTC filter in lav video?

I ask that because with 10bit video, I can't use ffdshow if not output is transformed in 8bit. With only lav video chain stay in 10bits.

I wonder if you've change anything?
If so it is nice to give out a diff file for the changes. (git diff > changes.diff is handy)

Nev,

I've come across a strange possible bug in LAV Filters with LAVCUVID.

I'm using it with PotPlayer in dual head, playing video on one screen while I do other stuff on the other screen, and sometimes something like a facebook game can make the video play with reversed field order (I think... its really jittery/wrong looking).

If I pause/play it works perfectly again.

Currently on a fresh format of Win7 64bit/GTX260 card, EVR CP.

Any suggestions of how I can further troubleshoot?

The only patch I used is your rv seek on keyframe patch.

There are some experimental patches for ffmpeg, but they dont really work all that well. It may however be a basis for future developments - who knows.

That's usually an indication that you're not doing bit-perfect playback. What are your settings, filters, player, audio device, and OS?

Problem with Death Magnetic is that it's so poorly mastered. There are songs which have dynamic range under 3db. Also, no plugin is involved in this. I'd never use DRC or some other "enchancement" effect for listing to music. It's a pity that so lots of new songs suffer from poor mastering just to sound louder, especially metal.

I did few listening tests with different VST equalizer (Linear Phase Graphical Equalizer 2.1) and I didn't notice anything similar to electri-q. It definitely boosted bass range I chose, but without noticeable distortion with same samples, even with bigger values. So there must be something wrong with electri-q, maybe not preventing from clipping like both ouf you said, or some algo errors in free version.

Anyway, thanks for making things clear. So I'll use reclock's DRC for movies, since you guys claim it's working just fine.

Unpatched nightly builds (x86 and x64) :
Non-installer: LAVFilters-git-r1368(85d0d90).7z
Installer: LAVFilters-git-r1368(85d0d90)-Installer.7z

Happy to see that both libav and ffmpeg has supported both intra and inter/lossless H.264 4:2:2 decoding. Hope for the update of ffmpeg in lav's repo.

Not totally off topic... from the Icaros README file,

Code:
the requirements are the following:

	1. LAV Filters
	2. .NET Framework 4

Thanks Shark & co.
Now that we have a single filter that can split and decode almost anything and a true thumbnailing capability without the need for Media Foundation, suddenly, MF importance have just dropped dramatically.
The only wish I have is an option to choose the method of thumb extraction point: percentage based, which is implmented now or fixedtime based.

Though Microsoft did this for a big reason and that's the stability of Explorer and ehmm not to sound rude but lav splitter isn't stable as it would be needed to make Microsoft happy to replace one of their core functions in the OS. And getting dshow back for the Thumbnail creation seems a risky thing (unless you turn of the dynamic graph creation and only allow manual connections) as well in terms of crashing caused by interferences of other filter or vfw components that could get loaded as well, not to forget to think about the Security aspect as well.
