Creating farms of unique websites
13 avril 2011, parMediaSPIP platforms can be installed as a farm, with a single "core" hosted on a dedicated server and used by multiple websites.

vaapi_encode_h265 : Reduce SAR to valid range

FFMPEG screen regarding using gdi is working as expected when given offset, width and height on different screen size ?
15 novembre 2018, par Mohsin AbbasI am working on an application that records the screen using ffmpeg. The recording works fine when I don’t specify offset, width and height.
When I specify the offset, width and height on my device and records according to the area but when I run it on a big screen and it records smaller area than provided. I am using following command to record :ffmpeg -f gdigrab -framerate " + Framerate + " -offset_x " + OffsetX + " -offset_y " + OffsetY + " -video_size " + width + "x" + height + " -show_region 0 -i desktop " + FileName;I think ffmpeg don’t take screen resolution into account or something ?
