DNLA Streaming Server transcoding stuff etc.

h1ght · June 17, 2019

Hello,

im figuring out, how i can archieve a good streaming setup at home.

currently im running a i5 7600k [5ghz with -2 avx offset at 1.32v llc mode 1]paired with a rx vega 64 as my gaming rig and testing the universal media server (ums) its a opensource thingy and does the same as the others like plex, serviio etc.

we got a small full hd tv in the kitchen and a other full hd tv in the living room. one got a ethernet connection to our cable router (avm 6590) and the smaller one a chromecast stick. currently my mom is watching a transcoded 4k movie with chromecast over wifi. it works so fine, but i cant think of using my pc for gaming or browsing the internet etc. ums using ffmpeg aswell as other stuff, but as i seen so far all streaming servers cant handle AMF/VCE properly. they just using decode stuff, not encode.

anyway, im thinking of buying new hardware dedicated for downscaling 4k stuff x264/x265(avc and hevc, maybe 10bit and hdr stuff aswell) to 1080p

synology got good nas with transcoding, up two 2 streams downscaled. i read somewhere, nvidia shield does a good job too. the new ryzen 2 stuff and aswell as the latest apu's using VCN instead of uvd/vce at all. some1 has reliable benchmarks for it? i dont wanne buy nvidia gpu so far, because it will be useless so far. then ive to build a new rig etc.

is there anything, affordable to buy? i know i can grab some used 2 socket many core thingys and setup own server/box/nas with such software etc. but it isnt that handy. and not cheap.

does ffmpeg using nvenc/cuvid properly on nvidia gpu's? and which of them are siuted for such task's as i intended to use. e.g. decoding and then encode at the same time not wasting 99% cpu time on a decent rig?

specs about the content, video bitrate up to 82mbit/s (untouched bluerays e.g.) avc and hevc aswell, dts, hdr 10bit, transcoded to 1080p, i think x264 is the most common.

i read hevc is the heaviest in software aswell as hwaccel stuff.

regards

PS

Maybe im the wrong section, if a mod come to the same conclusion it can be moved to hardware.

Synology works great for transcoding but its not gonna work for 4k 60 or 10 bit HDR content which is actually not the easiest thing to do on any system right now as going from HDR to SDR also means its a totally different color space and can fuck up the colors.
