Can you elaborate? AC3 is an audio codec (it's another name for Dolby Digital) not a video codec?

Yes.... a container with pass through video, but audio transcoded to dolby digital, ac3. I'd usually do with via ffmpeg cli, but not sure i can do that in TVH

There is option by using Spawn profile

Oh wow, I've been hunting through the settings and docs, not seen anything like that, but it does sound like what I need.

is it in the ppa releases, or do I need to build?

Thanks

Neil

With version you use?
Building yourself have more positives then stock from some repo.

dpkg --list | grep tvh

ii tvheadend 4.2.8-23~g74cdf3f16~bionic amd64 Tvheadend

This was from https://tvheadend.org/projects/tvheadend/wiki/AptRepositories

I've just looked at the output from ./configure --help and i see no mention of a 'spawn' profile

I've searched for 'spawn' profiles and whilst I can see how it works (a nice shell script with ffmpeg, whatever inside), I cannot for the life of my, see how to make this an option available to me?

It's embedded in code it's not a option.

If you need help how to build latest version from git

That's ok then, but please tell me how to select this as a profile?

I'm a dev myself and I'm assuming there'd be a stream profile called 'spawn', where the option / argument would the binary plus args, or a shell script?

Okay, I'll answer this myself... the 'spawn' feature is a part of the 'development' / unstable package.

It's very stable actually.
