Hi, help how to best nvenc faststart tvheadend.
How can this be done faster, or is it possible that the quality is poorer? The problem stops after 4-5 minutes.

or:

Code:
/usr/lib/jellyfin-ffmpeg/ffmpeg -y -hwaccel cuvid -c:v mpeg2_cuvid -i pipe:0 -c:a aac -ac 2 -ar 44100 -b:a 128k -c:v h264_nvenc -b:v 700k -f mpegts pipe:1

not working:

Code:
/usr/lib/jellyfin-ffmpeg/ffmpeg -hwaccel cuvid -threads 4 -i pipe:0 -map a -map -m:language:HUN? -map v -vf 'drawtext=textfile=/usr/lib/jellyfin-ffmpeg/info.txt:x=(w-text_w)/2:y=(h-text_h)/20:fontsize=20:fontcolor=white' -codec:v h264_nvenc -profile:v baseline -preset:v ultrafast -coder 1 -tune zerolatency -mbd rd -codec:a copy -strict experimental -async 1 -sn -fflags +genpts -metadata service_provider=STRING -metadata service_name=STRING -f mpegts pipe:1 -movflags +faststart
