Description

Trans-coding Live TV the stream profile is honored, when applying the same stream profile to DVR content playback it is ignored and the full stream is sent. This overloads WAN links

Client VLC
playback stream
Live TV - transcodes fine

HTS Tvheadend 4.1

This is because Tvheadend only transcodes live streams not recordings, it is a wanted feature.

IIRC it is already implemented here https://github.com/lekma/tvheadend/tree/codecs at the complete overhaul of the transcoding. So just sit and wait :)

Lekma's has been merged, but still recordings don't get transcoded when streamed, AFAIK.

So we have transcoding while recording and during live tv playback... and IMHO - since storage is plain cheap - recording profiles get more and more a nice feature. i never used it personally. But especially for mobile access the streaming profiles easily get the killer feature.

So I would really appreciate to have streaming profiles respected for playback of recordings (also to have the full experience when using Kodi via WAN).

Cheers,
Diddle

I'd like to see this too. I recently set up TVHeadend with some HW transcoding profiles so that I could watch TV on my phone while on a different network than TVHeadend, since my upload speed is not fast enough to stream the untranscoded material. This works great for live TV but doesn't work at all for recordings. I don't want to transcode while recording because I don't need to for disk space reasons, I don't want to reduce the quality for local playback, and my hardware transcoder is only capable of transcoding 3 HD streams at the same time without dropping frames but I have 4 tuners. Being able to transcode on-demand while playing recordings would be very nice.

Definetely a wanted feature. Same reason for me as Michael wrote.
Is there any work ongoing for tvheadend?

Played around with (vaapi) transcoding in TVH... cool feature. :)
Stumbled over this annoying limitation, that playback of recordings does not respect the streaming profiles. That's really a pity.

I'm not familiar with the code and architecture of TVH.
Would it be complicated to enabled this, at least for recordings that used the PASS profile? Handling should be quite similar as for live streams, I guess.

Thanks in advance
Rich

+1 to implement this.

That would be a very nice feature to have when using mobiles to play recordings...

(I'm sure I've already asked for this feature in the past)

Although I would like to see the whole MPEG-TS data handling re-written first :) (#3991)
