[x11grab @ 0x558aae75d860] Stream #0: not enough frames to estimate rate; consider increasing probesize
Input #0, x11grab, from ':0.0':
  Duration: N/A, start: 1499569061.452458, bitrate: N/A
    Stream #0:0: Video: rawvideo (BGR[0] / 0x524742), bgr0, 1366x768, 30 fps, 1000k tbr, 1000k tbn, 1000k tbc
Codec AVOption cutoff (set cutoff bandwidth) specified for output file #0 (TEST003.flv) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Codec AVOption b (set bitrate (in bits/s)) specified for output file #0 (TEST003.flv) has not been used for any stream. The most likely reason is either wrong type (e.g. a video option with no video streams) or that it is a private option of some encoder which was not actually used for any stream.
Stream mapping:
  Stream #0:0 -> #0:0 (rawvideo (native) -> h264 (libx264rgb))
