Re: Upgrade Opus 1.1.5 to the faster & better Opus 1.2

1.2.1 is released:
Yeah, we had to do a 1.2.1 release to address an issue where the encoder would sometimes think the signal is low-passed at 12 kHz and not encode information above that. So it's better to upgrade to 1.2.1.

Re: Could fdk-aac be included in the shared builds?

The internal aac encoder still has a long way to go: https://hydrogenaud.io/index.php/topic, ... #msg914980

Would be interesting to see how it actually performs against libmp3lame and libfaac.

Re: Shine: fast fixed-point mp3 encoding

I tried out libshine in liquidsoap, but the I couldn't get decent enough quality out of it no matter what bitrate I used. It doesn't have any Psychoacoustic Model.

It might be useful for real-time encoding on something like a rasberry pi, but win32 doesn't run on it.

Re: DirectShow Capture support

I've got 2 different USB DVB-T2 devices that I can use to help with testing. Currently I am using ProgDVB to dumb raw streams to my hard-drive.

How do you specify the frequency and channel?
Would '-vcodec copy' and '-acodec copy' work with this?

Re: building ffmpeg with lib-voaacenc

OK I got the 64bit build working now (ran vcvarsall amd64 before msys) Here is a summary of ALL the speed tests I ran. I double checked the ffmpeg-latest-win32-zeranoe one and yes it really is that slow. The ffmpeg-2.8.5-win64-zeranoe aac encode @ 325fps vs libvo_aacenc @ 425fps on v2.8.5 would be ...

Re: Native AAC Encoder - Remove libvo*

By HE-LC I assume you mean HE-AAC.
The Native ffmpeg AAC encoder only supports LC-AAC just like libvo_aacenc.

Re: Native AAC Encoder - Remove libvo*

Seems like it doesn't really matter. The native AAC encoder has a higher priority than libvo.
So 'ffmpeg -i someAudio.wav someAudio.m4a' will automatically use the native AAC encoder when no codec is specified.

Re: Native AAC Encoder - Remove libvo*

Finally! :)
Now vo-aacenc can be removed from the builds.

Re: AAC Encoding - Native FFmpeg AAC encoder vs. libvo_aacenc

This might sound like a weird request, but I think it would be beneficial to remove the 'vo-aacenc' AAC encoder from the builds. The sound quality produced by vo-aacenc is far worse than the built-in AAC encoder and people might accidentally use vo-aacenc when they don't specify which AAC encoder to...

Re: AAC Encoding - Native FFmpeg AAC encoder vs. libvo_aacen

The native encoder will create better sounding output than libvo_aacenc, but I wouldn't personally use it. You would get a big quality increase by just using libmp3lame instead.
