	[nut @ 0x3f05740] Codec for stream 0 does not use global headers but container format requires global headers
	Output #0, nut, to 'concat.nut':
	Metadata:
	encoder : Lavf57.23.100
	Stream #0:0, 0, 1/51200: Video: h264, 1 reference frame (H264 / 0x34363248), yuv444p(left), 320x240 (0x0) [SAR 1:1 DAR 4:3], 1/51200, q=2-31, 25 fps, 25 tbr, 51200 tbn, 51200 tbc
	Metadata:
	encoder : Lavc57.22.100 libx264
	Stream mapping:
	Stream #0:0 -> #0:0 (copy)

	cur_dts is invalid (this is harmless if it occurs once at the start per stream)
