LAV Filters - DirectShow Media Splitter and Decoders

Thanks for confirming.
Seeking got better (faster, more responsive) with the new demuxer although the old one was already pretty good.

Sorry if this question has been asked before but I can't figure how to search inside threads.
LAV doesn't have any systray icon, but is there a way to check if the LAV audio decoder is active while playing a video?
Thanks

I'm not getting default subtitles selected in any mkv with new demuxer.

If you're using MPC-HC. While the video is playing right click anywhere in the video, choose filters. I think that is the case too in Potplayer (correct me if am wrong anyone).

Here is an example. Credits to Haruhichan weblog:

ADTS AAC + LAV 0.40 + ffDSHOW libfaad2 = auto seek to EOF, no playback. :/
works only with isomM4a or with libavcodec as AAC decoder in ffDSHOW.

Should be fixed.

Then, why not just use libavcodec?
Also, it should be fixed - it was however ffdshows fault, it accepts a media type which it doesn't understand, faulty design imho.

Hello Palladin, thanks for your answer. Is there another way to check if LAV Audio is active? Cause I'm using Windows Media Center on Win 7 64.

nev, found a bug in your last "official" build: default flags are ignored. The first audio track and the no subtitle track are always selected, as if the file had no flags.

edit
you know, i think something just went wrong with the muxing, so this isnt a lav splitter issue.

I'm using libfaad, too actually.

There was an issue with libavcodec's AAC decoder playing certain types of AAC streams that didn't have issues on the older libfaad decoder. However, if I remember the release notes from the latest CCCP, the new version of ffdshow it ships with should have gotten those issues fixed. I haven't tried it to find out though.

Looks like LAV is only seeing 5.1 audio inside a DTS-HD MA 7.1 file like http://www.trailerz.demo-world.eu/hd...t_lossless.rar, even with dtsdecoderdll.dll in use?

Known issue?

Thanks, Lee

Its just a cosmetic issue, if you decode it, LAV Audio should say 8 channels on its status page - just LAV Splitter doesn't know that.

That was fixed last night.

LAV Audio says 6 channels. I tried a couple of different demo 7.1 files, but LAV Audio says all of them are 5.1.

For a sanity check, I tried a Dolby HD 7.1 clip http://www.trailerz.demo-world.eu/hd...t_lossless.rar and both LAV Splitter and LAV audio reported 7.1.

Then you failed at putting the dts dll in the proper directory, or are using a very old version of the dll and forgot to install the required runtime (which would be automatically installed if you installed TMT. )

TBH, that change isn't all that useful for us.

[fastplayer]

It was more of an FYI. Quite a few times people have asked for a libass-based sub renderer here on D9. Now it's on ffmpeg which is "usually" a good sign.

You can use this tool to set your preferred DirectShow Decoder in w7. Select LAV audio for audio formats you want MC to decode and MC should use it.
