Lav Filters

[lorac 118]

What about using junction to make a hard link from ET LAV to the LAV install?

[Guest asrequested]

For my issue, LAV doesn't process AAC. I either have to remux (which I've done with a few) or I use ffdshow or just listen in stereo. I may just go through the entire collection and remux the relevant files. It'll take a while. Damn you, yify lol

And I probably should apologize for totally hijacking this thread

@@Luke Can we please have these options back? At least for MP3 and AAC. I have so many old shows and movies that have stereo tracks that don't get processed, and I have to finagle with my receiver settings. To be allowed to use other processing software would be so great. PLEASE! PLEASE! PLEASE! I implore you.

Is it not possible to have the server transcode AAC 2.0 to AC3 2.0 (or 5.1) using ffmpeg on the fly?

Right now there's just not a large enough audience for this feature.

Well the server is capable but there isn't really any configuration you can use to force that to happen.

Not even in a server profile? Is it possible a profile for Emby theater, just like Chromecast and Roku?

[Luke 42077]

There is a profile yes but it is embedded into Emby Theater. It's not exposed for configuration at this point.

I'd really like to get AAC to AC3 audio transcoding (at least for 6 channel audio) - I just searched through my movies and I have just over 100 with 6 track AAC and these all play back as stereo PCM with ET.

 

I've already manually re-encoded some to 5.1 AC3 but I don't relish doing it for all 100.

Okay. Normally only power user would need to change that.

 

Could you show us where, so we can poke around

[Luke 42077]

It's not in a place where you can get to it, but perhaps in the future.

Ffdshow can process AAC to AC3 on the fly, very well.

I've converted some of mine, too. 

 

@@Luke I'm not alone in this. How much demand would it take to have this implemented?

That shouldn't happen. What audio connector are you using?

[AdrianW 1058]

This is happening on two different PCs (my desktop and my NUC) - one is connected via HDMI and the other via SPDIF.

 

My desktop (SPDIF) has these settings under "Playback / Audio" in ET:

• Speaker Layout: 5.1
• Audio bitstreaming mode: SPDIF
• Audio Renderer: WASAPI
• Dynamic range compression: None
• Expand mono: Yes
• Expand 6.1 to 7.1: Yes
• WASAPI audio device: Default Device

The NUC is similar except it has Audio bitstreaming set to HDMI

 

My receiver always shows PCM 2.0 when playing AAC 5.1.

On the SPDIF system, you will only get two channels PCM. That is expected.

 

On a HDMI system using the WASAPI renderer you should get 6 channels. You can get 6 channels w/o the WASAPI renderer if you set the speaker settings in Windows to 5.1 as well. If this isn't working correctly, we can debug further.

I can confirm this works on my system with both WASAPI and ReClock. 6-channel AAC decoded and output as 6-channel PCM via HDMI.

You can add me to the list of those wanting to be able to tweak advanced settings in LAV - even if it's just setting the settings in LAV's guis and having the settings stick.  I'm more about the video settings, but both would be nice.

FWIW, the settings are the same (or greater) in ET v. MBT, just not exposed through the UI yet. Dig into the XML file, it's all there.

Yes, that's true of some settings, but they're not all in there.  One I'm particularly interested in is the ability to enable software deinterlacing (yadif and/or w3fdif) as those provide far superior results to madVR's deinterlace for live tv.  If it's available and I just need to know the key name to add, then that's cool.  I have no issues with editing the XML.

 

Right now I can make that change via LAV's gui and see the results, but of course that only changes it for the current playback - it doesn't stick.

I didn't say every setting LAV has... Just that what ET has is a superset of what was available via MBT.

 

What GPU do you have that SW DI produces better results than HW? It's not hard to add addition settings to the backend (xml). If you make a [short] list, I can commit to throwing them in.

[Guest asrequested]

My problem is that even if all of LAV's settings were exposed, it isn't able to process to AC3. We need something else. I started a new thread about having those settings back

The settings that were in MBT are in ET, they just aren't in the UI. If you could do something via config before, it's possible to do it now.

[Guest asrequested]

Which file do I modify. I don't remember which one I tried, but when I removed AAC from it, nothing changed. Can you point me in the right direction?
