ALAC audio file support?

Well its hard for me too to live without m4a now, since 2 of my band members use iPhones and any recording they do will come over the wire as m4a format. I have no idea if and how they can influence the recording codec on their side. Until that I can only listn to this on my desktop. Which is boring.

Consumers are trapped in stuff they don't understand and also they are just no giving choices. We got along way to go...

@nekojet said in ALAC audio file support?:

gstreamer1.0-libav

Oh and by the way, definitely need encoding support for opus when we ever want Telegram voice messages to be a thing. How could we get this in @dobey

@Flohack m4a is the MPEG-4 container format. It's not related to the codec for the audio embedded in the file, which can be ALAC, AAC, or numerous other things.

@Flohack Well, Opus is an open codec, and it seems to already be implemented in the gstreamer1.0-plugins-base package, which should already be in the image, so I guess it should just work.

@dobey Seems you are right, its AAC internally, but it still cannot be played back by UT...

@Flohack On what device? I don't think we include a software decoder for AAC, so it depends on hardware decoder support, as AAC is non-free. It should work on FP2 and Nexus devices at least, I think. If not, there might be some low level issue with Android drivers.

@dobey I am on Oneplus One, that might explain the issue. Hmm good question if it can be enabled if it would be there theoretically ^^

@Flohack From a quick search, I can't seem to find a list of definite hardware audio codec support on opo, so no idea what it actually supports.

Regarding AAC support on OPO...

I did a fresh OTA-11 RC install and wipe on my OnePlus One. It's now running OS build number 2019-W41/2. I can successfully play a couple of example AAC files I downloaded from here:

Hope this helps!

@dobey @Flohack I also downloaded an example OPUS file from here:

http://samplephotovideo.com/2015/12/download-opus-sample-audio-file-opus/

I can successfully play the file using my clean "install and wipe" installation of OTA-11 rc (OS build number 2019-W41/2) on my OnePlus One.

Cheers!
