How to enable hardware transcode in TVH snap version?

m h

So I'm in the Configuration->stream->stream profiles menu. It lists the HEVC VAAPI codec, but it can't work. I don't know what settings should I change to make it work. Also has a libx265 codec, but it's only CPU transcoding, useless. h264 codecs also can't use the GPU.

I have an intel i3 8100 CPU, and using the integrated GPU. The hw transcoding works well in other programs like Jellyfin.

(Also I'm open to change to the apt version of TVH, if it would solve my problem. But the apt version cant't see my DVB-C tuners. These are network tuners (EyeTV Netstream 4C). I can't find the add-on which allows TVH to see my tuners. These addons are available in the snap version, which is working fine, except the hw transcoding. (And I tried some docker versions of TVH, one of them has the addon for the tuners, but can't find the channels.))

>> It lists the HEVC VAAPI codec, but it can't work.

TVH will list all codecs that TVH knows (not all codec that are supported by your VAAPI HW and Drivers).

if you want on-the-fly hardware detection for vaapi try:

https://github.com/tvheadend/tvheadend/pull/1531

Another option that is a little harder to follow (but has all info required to make Intel GPU transcode):
https://tvheadend.org/d/8186-tvheadend-build-and-install-on-lubuntu-20-04-64bit-with-igpu-8-for-gpu-transcoding?r=48662#message-48662

Follow the Gen 8/9/9.5 for your CPU (not 11+).

Note:
VAAPI transcoding require a particular set of drivers being installed. Also, Huc/GuC FW support must be enabled in your kernel.
You should try to build natively on your OS. mmarley has some distro with vaapi enabled (https://launchpad.net/~mamarley/+archive/ubuntu/tvheadend-git) - personally I never use it. In general, regular distro (ubuntu type) are not built with vaapi support.

Thank you guys! The transcoding is working now.
