Window capture performance on steam deck isn't good when playing the witcher 3 for example. The capture itself is fine but video encoding puts it to 30fps even if the game runs at 57 fps. diff --git a/src/main.cpp b/src/main.cpp index a7db997..05db5b0 100644 --- a/src/main.cpp +++ b/src/main.cpp @@ -632,8 +632,12 @@ static void open_video(AVCodecContext *codec_context, VideoQuality video_quality } } -static void usage() { - fprintf(stderr, "usage: gpu-screen-recorder -w <window_id|monitor|focused> [-c <container_format>] [-s WxH] -f <fps> [-a <audio_input>] [-q <quality>] [-r <replay_buffer_size_sec>] [-k h264|h265] [-ac aac|opus|flac] [-oc yes|no] [-v yes|no] [-o <output_file>]\n"); +static void usage_header() { + fprintf(stderr, "usage: gpu-screen-recorder -w <window_id|monitor|focused> [-c <container_format>] [-s WxH] -f <fps> [-a <audio_input>] [-q <quality>] [-r <replay_buffer_size_sec>] [-k h264|h265] [-ac aac|opus|flac] [-oc yes|no] [-v yes|no] [-h|--help] [-o <output_file>]\n"); +} + +static void usage_full() { + usage_header(); fprintf(stderr, "\n"); fprintf(stderr, "OPTIONS:\n"); fprintf(stderr, " -w Window to record, a display, \"screen\", \"screen-direct\", \"screen-direct-force\" or \"focused\".\n"); @@ -671,10 +675,12 @@ static void usage() { fprintf(stderr, "\n"); fprintf(stderr, " -oc Overclock memory transfer rate to the maximum performance level.
