svpcode and svpcast extensions was added just now
and they both use mpv for encoding

This's great, but SVP now needs more built-in encoders for transcoding and streaming - x265, QuickSync, AMD AMF.

> I'm surprised that SVP4 can't show the same good results for this goal.

Why? Only because it can't set "2 threads"? hmm
All settings -> set "frc.threads" = 2

I'm more surprised with the fact 2 threads can handle 1080p...
Which CPU do you have? Kabylake @5GHz ?

> how do you think this pipeline can be improved?

Probably by using mpv.

====

Just a little technical comment: number of threads is NOT a problem. The real problem is in ffdshow buffers size (open ffdshow properties, Avisynth tab, see "buffer back/ahead" values). In general, more threads need larger buffers -> gives higher latency, BUT you can adjust buffers size with frc.prefetch.ff_mul and frc.prefetch.ff_add values - <buffer size> = ff_mul * <threads> + ff_add. When the buffer will be too small for the given number of threads you'll see it wink

====

You can now set 2 threads in SVP 4 but you can't lower ffdshow buffer size below 7. Damn...

ah! the only difference I can see is different default encoder params:

svpcode:  "code.simple.opts.h264_amf" = "b=$B,quality=quality,profile=high,rc=vbr_peak"
svpcast: "cast.encode.opts.h264_amf" = "b=$B,quality=quality,profile=high,rc=cbr"

in fact you can try to put all the svpcast's params into svpcode's encoding profile (under "advanced" button):
b=4700000,quality=quality,profile=high,rc=cbr,g=60,keyint_min=60,refs=1,sc_threshold=0

Try the new .130 build.

- should be a little bit less CPU demanding
- added AMD AMF option (*)


(*) I can't check how good or bad it works, so please leave your comments wink
See the encoder options in "All settings": cast.encode.opts.h264_amf and cast.encode.opts.hevc_amf

Videostream encodes video for streaming with 5M bitrate.

> Nvenc doesn't matter as my gpu isn't being used when streaming anyways, mostly just the cpu.

You didn't read what I wrote sad Interpolation uses "mostly the cpu" and NVENC works just fine.

I'm wrong, it can do "native resolution", at least for 1080p...
but no NVENC smile

and 5M bitrate at maximum

good for you! now look in SVP's Events log...

and play some "normal" video, not 4K
your hardware obviously is too slow for streaming 4K
