Transcoding how to

Hello people,

I was wondering if some one can help me to correctly setup transcondig for channels. I have access to an iptv network and i have all channels mapped on tvheadend. All channels works without problems, but i need to transcode those channels in 480/720/1080

The problems is that i can't find any information about that, how to setup 3 codec profiles with 1stream profile.

I made a test using only 480 and it works great

Any idea?

Thanks

PD: Sorry for my really bad english Sad

Generally, use the Height attribute in the selected codec in TVH under Profile Settings and then set a bitrate under the codec settings. Alternatively you can set CRF (Constant Rate Factor) instead of bitrate.

There are many more things you can configure including hardware acceleration but to my experience Hardware Acceleration has been very problematic in TVH. Instead you can use your own ffmpeg binary and enable all kinds of acceleration there (QSV,VAAPI,NVENC) and then use this binary in TVH and pass parameters to it.
