NVEnc FFMPEG
#1
Hi Selur,

Bei mir läßt unter dem Encoder NVEnc FFMPEG (H.264) die spatial Filterstärke nicht einstellen. Die hängt immer bei "8" fest. Und das Setting für die  GOP-Länge taucht nicht auf. Kannst Du das mal bei Dir testen ? Hybrid ist aktuell und neu installiert worden unter W10.

Wenn ich Hybrid lade, NVEnc (FFmpeg)->Base->Adaptive Quantization aktiviere kann ich die aq-strength anpassen und die Command line wird angepasst.
Was gibt 'NVEncC --check-features' bei Dir aus?

Wenn Du mir sagst wie ich ffmpeg das für NVEnc sagen muss, kann ich ne option hinzufügen.

Ist ja nicht zu glauben, gerade mach ich die Kiste an, und nun läßt sich die "spatial Filterstärke" einstellen. Na gut.

GOP, REF und BF lassen sich z.B. mit "-g 24 -refs 3 -bf 3" einstellen (h264).
Bei hevc können nur keine Bframes gesetzt werden.

In meiner Mini-ffmpeg-GUI funktioniert das problemlos.

EDIT

Du mußt sicher nicht alles berücksichtigen. Wäre vielleicht interessant wenn man als User die Möglichkeit hätte, die fehlenden Optionen selber einzufügen. Bei QSVEnc hast du das ja freundlicherweise integriert: "Custom command line addition"

Super werde ich versuchen die Tage in Hybrid hinzuzufügen.
(momentan zu strikter Bettruhe vom Arzt verdonnert, aber es geht langsam wieder besser,..)

Dann wünsche ich Dir erst mal "Gute Bessserung".
