Transcodieren mit Nvidia(nvenc)!

[mango]

Hallo,

FFmpeg local gebaut -> /home/easyvdr um mit GPU-Unterstützung Filme zu transcodieren.
Warum "/home/easyvdr" softhddevice ist gegen ffmpeg-2.8.6 gebaut und ist dem System als ffmpeg bekannt.
Wird nun FFmpeg mit nvenc gebraucht muss auch der Pfad zu dieser Version angegeben werden.
Da die GT 630 nur h264_nvenc kann gibt es auch keinen Test mit hevc_nvenc.
Wer eine "GTX750TI" im System hat, kann auch mit hevc_nvenc transcodieren.
Anleitung gibt es hier -> https://trac.ffmpeg.org/wiki/CompilationGuide/Ubuntu
*-dev habe ich nicht installiert sondern alle Pakete neu aus Sources compiled ...FFmpeg wurde
nicht aus git geholt hier wurde Version 3.2.2 verwendet.

Code:

https://ffmpeg.org/releases/ffmpeg-3.2.2.tar.bz2
tar xjvf  ffmpeg-3.2.2.tar.bz2
