Transcoding does not work

Rainer Dorsch

Hi,

I setup a codec entry and a streamprofile entry for transcoding.

All I get is -vcodec copy (!)

ffmpeg -loglevel fatal -i https://swrbwhls-i.akamaihd.net/hls/live/667638/swrbwd/master.m3u8 -vcodec copy -acodec copy -metadata service_name=SWR Baden-Wuerttemberg HD -metadata service_provider=IPTV-DE -mpegts_service_type advanced_codec_digital_hdtv -f mpegts pipe:1

instead of

-vcodec libx264

Here is the streamprofile

On top of that there seems to be no audio :-/

and the corresponding codec

The tvh log confirms that the profile imx6 is used

Why is there

-vcodec copy

and no transcoding takes place?

I use a recent version of tvheadend: Build: 4.3-1940~gfe0e5f1f9 (2021-03-06T18:28:43+0100)

Because that's how you set it up in the input settings.

Transcoding is not done by ffmpeg but by libav, you won't see a ffmpeg process for that.

Since my current setup does not really work, whereas transcoded by ffmpeg works, is there a way to switch entirely to ffmpeg?

Can you tell where are the input settings? Could not find such a field in neither the streamprofile nor the codec dialog.

Can anybody tell, why there is no audio? Neither at the kodi client nor at the mpv player started from the web frontend.
