Encoding of two full hd streams in Linux + GPU with Intel HD4000 / VA API / FFMPEG / OpenGL
30 juin 2016, par qknighti want to encode/stream two full hd streams in realtime from my laptop to a remote location using linux/xorg on the host.
VA API
for this i’ve been playing with the VA API but the performance is pretty bad with 5.59 fps (see paste below).
FFMPEG
using ffmpeg with CPU encoding i get about 200 fps but then all cores of my Intel(R) Core(TM) i7-3520M CPU @ 2.90GHz are busy and the fan turns on.
future plans
i want GPU support in encoding and later integrate this into a program which streams a virtual xorg ’screen’, see https://lastlog.de/wiki/index.php/Raspberry_PI_virtual_screen for more details on my plans.
maybe h264 isn’t even what i want ? so if someone advices towards a different implementation, i’d welcome that.
besides VA API there seems to be QuickSync but i didn’t experiment with that yet as it is not packaged on NixOS just yet.
note : i need a library to have a smooth integration into the code.
h264encode -w 1920 -h 1080 —profile MPSource frame is 1920x1080 and will code clip to 1920x1088 with crop
