	1 # Ads should be moving.
	2
	3 People know the ads showing at brcon2023:
	4
	5 gophers://bitreich.org/1/con/2023/ads
	6
	7 There is already a subformat:
	8
	9 -before is played before the -after ad.
	10
	11 But there is a reason, why those files end in .vtv. The last v stands for
	12 video. It hasn't been implemented yet.
	13
	14 It would be pretty simple:
	15
	16 $frame0
	17 $frame1
	18 ...
	19 $framen
	20
	21 The frames have a hard-fixed size, so reading a frame and displaying it
	22 is simple.

	24 ## Making a video player.
	25
	26 This should be a simple shell script.
	27
	28 ## Optimisations
	29
	30 People know ncurses, the library. Why do we need this overcomplex
	31 library? It knows buffering and can send the diff of one buffer over the
	32 line, instead of sending the whole line. We have many vtXXX commands in
	33 the virtual terminal to simply just replace parts of it.
	34
	35 Can we do it and use it for the vt videos?
	36
	37 ## Compression
	38
	39 This should be pretty simple, once we get the differences done. Then
	40 compare the known compression formats against eachother.
	41
	42 Have fun!
