HW acceleration for (DVB-T2) transcoding - command line

[the_majkl]

Hi,
I use this command for transcoding DVB-T2 stream to two separate MPG streams (for our old clients):

start "" "C:\Program Files (x86)\VideoLAN\VLC3011\vlc.exe" --meta-title="DVB-0 CT24 CT-D MASTER 8010,8020" ^
dvb-t2://frequency=514000000:bandwidth=8 :dvb-adapter=0 :live-caching=1000 :programs=272,276 ^ --sout=#transcode{vcodec=mp2v,height=576,acodec=mpga,deinterlace,ab=128,channels=2,samplerate=48000}:duplicate{dst=http{mux=ts,dst=:8036},select="program=272",dst=http{mux=ts,dst=:8025},select="program=276"} ^
:sout-all :sout-keep

It works, but CPU (i5) in the Windows machine goes 100% and it can not manage to generate the streams in real time. Is it possible eg to buy some graphic (which one?) card and make VLC to use HW acceleration for the transcoding (what option with?)? Or any other ideas?

Thanks Michal

bottleneck is decoding, not encoding to mpeg2

Thanks for your answer Any advice how to solve the bottleneck, please?

Will graphic card Radeon RX 570 help? It supports HW HEVC decoding/encoding. Will VLC be able to use it?

Thanks.

I don't know. Is that playback working without transcoding ? cpu usage ?
