Hi @Jhans ,
I finally found the reason why I couldn’t record RTSP via Qgroundcontrol with “Force Nvidia Hardware”. The problem was the streaming codec, “Force Nvidia” only records if streaming is set to h264 (I was streaming in h265/h265+). It has nothing to do with the Nvidia graphics configuration (beyond the quality improvements offered by its configuration). I have tested it, in fact, with Intel graphics and with Nvidia graphics and both record video.
I really don’t understand why, because you can view the video stream in h265+/h265 with “Force Nvidia”.
As I already told you, you can also record in h265+ / h265 with “Force DirectX 11”, but the live video stream is somewhat worse, at least on my PC and graphics.
Note: All recordings save .ass files
This week I will make a video with the different encoding formats to show the quality of the video recorded in Qgroundcontrol in 4k / 60fps/ 16000 kbps, with the telemetry overlay and thus be able to compare the quality.
Regards
