TvHeadend, Transcoding and field Expert Settings -> Parameters

Added by Stefan Dietzel about 6 years ago

Hi,

I am a litte bit confused about how to add parameters for a software transcoding.

I tried to use libx264 and added the following expert parameters:
-hwaccel vaapi -hwaccel_device /dev/dri/renderD128 -hwaccel_output_format vaapi -c:v h264_vaapi

My problem is that those parameters are not used. Is there a special format how I have to add the parameters?

I know that I can directly use vaapi transcoding but the quality with an intel GPU is very bad for low bandwith.
If I use own parameters on command line I get a much better quality. This is a first try how to use own parameters.

Thanks in advance,
Stefan

Use pipe option spawn profile to do that.

Hi,

where do I find this option?
I don't see it in Codec Profiles (see attached screen on first post).

Thanks
Stefan

I am compiling my TVH version by my own and have the latest version from the repository:
Build: 4.3-1496~g275aec3c3 (2018-10-24T05:08:11+0000)

I still not find this option under Configuration -> Stream -> Codes Profiles -> libx264
Am looking at the wrong place?
