			Some ARMovie-specific codecs are documented below.

			=== Moving Lines ===
			This codec operates in RGB555 or YUV555 format. It reads one or several 16-bit words to determine operation.

			Control word with LSB set means raw pixel value in top 15 bits. Otherwise depending on those top 15-bit value range a specific operation should be performed:
			* <code>[0x0000..0x4800)</code> -- motion compensation from previous frame. Low 6 bits are copy length minus two, top 9 bits are motion vector table index (you can decode it as <code>val = idx + (idx >= 144; dx = (val % 17) - 8; dy = (val / 17) - 8;)</code>
			* <code>[0x4800..0x7300)</code> -- motion compensation from current frame. Operation length is the same as in previous case, motion values can be decoded as <code>dx = (idx - 0x120) % 19 - 9; dy = (idx - 0x120) / 19 - 9;</code>
			* <code>0x7300</code> -- end of frame marker;
			* <code>[0x7301..0x7800)</code> -- run. Low 6 bits are run length minus two, next 16-bit word is run pixel value;
			* <code>[0x7800..0x7C00)</code> -- skip. Low 10 bits are skip length minus one;
			* <code>[0x7C00..0x7FFF]</code> -- raw data. The following 16-bit words will contain continuously packed 15-bit values.


			=== Moving Blocks ===
			This codec operates on 4x4 blocks in YUV555 format. Each 4x4 block has three coding modes: raw, motion compensated (from previous or already decoded part of the current frame) and subdivide it into 2x2 blocks and code them in raw or motion compensated mode.

			Format specification may be found
			[https://www.chiark.greenend.org.uk/~theom/riscos/docs/apps/AcornReplayMovingBlocks.txt here].

			=== Moving Blocks HQ ===
			TODO

			=== Super Moving Blocks ===
			TODO

			=== LinePack ===
			This codec takes 16-bit little-endian words for input and outputs 15-bit RGB or YUV.

			If top bit is not set the word is pixel value, otherwise bits 12-14 signal the operation and low 12 bits (with some exceptions) transmit number of pixels to perform the operation on (e.g. run or skip length).

			Known operations are:
			* 0 -- leave pixels unchanged from the previous frame;
			* 1 -- motion: bits 0-2 are horizontal motion component plus four, bits 3-5 are vertical motion component plus four, bits 6-11 are operation length. Zero displacement means copying pixels from the line above, other values denote an offset in the previous frame;
			* 2 -- run. Next 16-bit word is run value;
			* 3 -- raw pixels (16-bit values are transmitted in the following bytes);
			* 4 -- four-colour pattern. Next four 16-bit words are four colours, the following 16-bit words contain 2-bit colour indices for the pixels (LSB first);
			* 5 -- pixel pair run. The following two 16-bit words are two colours that should be repeated the specified number of times.

			=== Movie 16:3 ===
			This codec codes 4x4 blocks in RGB555 format using 16-bit control words (though if pixel value is stored in control word, blue component there has only 4 bits). Two top bits specify operation:
			* 0 -- fill block with the pixel value from the low bits;
			* 1 -- copy block from previous frame with displacement. Horizontal displacement is stored in bits 0-4 (plus sign in bit 10), vertical displacement is stored in bits 5-9 (plus sign in bit 11);
			* 2 -- patterned fill. Low 14 bits from the control word are the first colour value, low 15 bits from the next word are the second colour value. If top bit on the second word is not set, read 16-bit mask word and fill the block with those two colours; if top bit is set, another pixel is read -- if its top bit is not set, this is a raw tile and 13 more pixels need to be read, otherwise read 5 more pixels and 16-bit mask and do two-colour 2x2 block patterned fill like in [[Microsoft Video 1]];
			* 3 -- paint block with three colours. For that another 16-bit word is read, top 2 bits are used for paint mode, low 14 bits are pixel value. The third colour is an average of those two colours. The patterns are ('1' mean interpolated colour):
			0 1 1 2 0 0 1 1 0 0 0 0 1 1 0 0
			0 1 1 2 0 1 1 1 1 1 1 1 1 1 1 0
			0 1 1 2 1 1 1 2 1 1 1 1 2 1 1 1
			0 1 1 2 1 1 2 2 2 2 2 2 2 2 1 1
