Tvheadend

@ Di Bo
remove limit of zero audio streams.

Install official version.

I installed HTS Tvheadend 4.3-2100~gd1366a066 (latest official build?) now on three different machines as described here [https://tvheadend.org/projects/tvheadend/wiki/AptRepositories]. The problem persists. No audio transcoding / empty audio stream on all networks, devices and channels on all servers. Set the limit of zero audio streams (automatic setting) higher. No change. All codecs should be installed. Is this a mistake on my side or can someone reproduce this?

You have "Limited audio tracks = 0"

What do you mean? The "no limit" standard value is zero, but as I said before even setting to a higher number makes no change. There is still no audio on all machines I tested when the sound is supposed to be transcoded.

Standard value is 1

Did this ever get anywhere? I am getting the same exact problem.
I've tried all combination: only thing that works is "copy" on the audio codec. Everything else results in a no audio output.

I am on 4.3.0~pre+202304020018-0~built202304021716~gita10f7ea44~ubuntu20.04.1

Just to add some information: the ffprobe output above shows that the audio stream isn't even being delivered

Where can I get the official version for Ubuntu 20.04 ?

I installed this one via

add-apt-repository ppa:mamarley/tvheadend-git
apt-get update
apt-get -yqq install tvheadend

following the instructions here https://tvheadend.org/projects/tvheadend/wiki/AptRepositories linked from https://tvheadend.readthedocs.io/en/latest/install_tvheadend/

I was eventually able to do it (it's hard with https://doozer.io/ being down, and the unstable file descriptors referring to unexacting files), but with version 4.3-2115~ga10f7ea44 this problem is not present.

I spoke to soon.

The problem isn't present when the original audio track is `MPEG2AUDIO` but it still doesn't work if the original track is `AAC`:

this works. Ffprobe shows

Does not. FFprobe shows:

So the audio track magically disappears.

I believe `4.3-2115~ga10f7ea44` is an official version, so is anyone able to help ?

Thanks

A possible variance is that the example that works has multiple audio sources in english, the one that doesn't work has only one audio track in portuguese. I wonder if this makes a difference.

In both cases, using `COPY` for the audio transcoding, produces working audio outputs.

Thanks

Hi.

"Good" to hear I am not the only one with this problem.
As I said before I tried all kinds of inofficial and official recent builds on different hardware and the no audio transcoding problem occurs on all of them.

I know this worked earlier but I cannot remember up to which version.

So if anyone finds out what causes this please share it here.

Do you have it for all streams ? I find it intriguing that for some streams it works, for others the audio tracks are simply supressed.
The only pattern I noticed so far was the format of the source audio: if the source audio is MPEG2AUDIO it works well, if it is AAC, the audio track disappears.
Are you seeing the same ?
