• Parameters of game recording and streaming

  • [am.debug]
    continuous_recording_fps = u32!60 ; 30 or 60 FPS, default: 30
    continuous_recording_video_bit_rate = u32!0x780000 ; 7.5Mbps(0x780000 = 7,864,320), default: ~5Mbps(0x4C4B40), VBR(Variable Bitrate)
    continuous_recording_key_frame_count = u32!15 ; One I-frame in 15 frames (with other 14 P-frames), default: 15

  • Recommended: dvr-patches: Allow screenshot/recording in any games and remove overlay image (copyright notice or logo).
    • For optimal streaming experience, SysDVR via USB interface is recommended.
  • Known Issues (won't fix)
    • Game recordings may be less than 30 seconds if higher bitrate is used.
    • It has noticeable performance impacts in demanding games.
    • Video duration shown in album will be doubled, while the playback speed or mp4 file itself are not affected.
