tvheadend & transcoding with pipe (ffmpeg) causes pixelation in image

Added by Gerog De almost 5 years ago

pipe:///usr/local/bin/ffmpeg -hwaccel cuvid -c:v h264_cuvid -i "LINE" -c:a copy -c:v h264_nvenc -preset llhq -rc cbr_hq -b:v 5M -maxrate 6M -bufsize 3M -zerolatency 1 -flags +global_header -f mpegts -async 1 -vsync 1 pipe:1

Anything else need adjusting?
Are there tvheadend-filters for pixelation or an extra program?

HTS Tvheadend 4.2.8-33~g8ef4c0c28

where can I check in the Tvheandend if it is switched on? (nvenc)

I need a recon please...

If I want to create a new nvenc streaming profile, I have to select transcode/av-lib?
In the transcode/av-lib profile I can not insert a pipe,
Does it perhaps need to be installed something in addition?
