video encoder/decoder using the ffmpeg avformat/avcodec libraries.

|

The video decoder plugs into the media decoder functionality on media with an 'av:' prefix, specifically:
|
||||
The console command 'playfilm av:c:\foo.mpg' will start playing back c:\foo.mpg fullscreen.
|
||||
The shader term 'videomap av:c:\foo.mpg' will play the video upon the shader. This can be used with csqc+drawpic, csqc+beginpolygon, or placed upon walls.

The video decoder plugs into the media decoder functionality on media with an 'av:' or 'avs:' prefix, specifically:
|

The console command 'playfilm av:foo.mpg' will start playing back $BASEDIR/$GAMEDIR/foo.mpg fullscreen (or from inside paks/pk3s, but make sure seeking is fast, so avoid compression in pk3s...).

|

It theoretically supports any file that the avformat/avcodec libraries support, but has no ability to pass arguments, thus playback is likely limited only to files which require no explicit overrides.
|

|
||||
The video encoder plugs into the existing capture command. Or something. I don't know. Its all basically junk.

* version 1.1, 16 Feb 2003
|
||||
*
|
||||
* blast.c decompresses data compressed by the PKWare Compression Library.
|
||||
* This function provides functionality similar to the explode() function of
|
||||
* the PKWare library, hence the name "blast".
|
||||
*
|
||||
* This decompressor is based on the excellent format description provided by
|
||||
* Ben Rudiak-Gould in comp.compression on August 13, 2001. Interestingly, the
|
||||
* example Ben provided in the post is incorrect. The distance 110001 should
|
||||
* instead be 111000. When corrected, the example byte stream becomes:
|
||||
*
|
||||
* 00 04 82 24 25 8f 80 7f
|
||||
*
|
||||
* which decompresses to "AIAIAIAIAIAIA" (without the quotes).

|

* Format notes:

*
|
||||
* - First byte is 0 if literals are uncoded or 1 if they are coded. Second
|
||||
* byte is 4, 5, or 6 for the number of extra bits in the distance code.
|
||||
* This is the base-2 logarithm of the dictionary size minus six.
|
||||
*
|
||||
* - Compressed data is a combination of literals and length/distance pairs
|
||||
* terminated by an end code. Literals are either Huffman coded or
|
||||
* uncoded bytes. A length/distance pair is a coded length followed by a
|
||||
* coded distance to represent a string that occurs earlier in the
|
||||
* uncompressed data that occurs again at the current location.
|
||||
*
|
||||
* - A bit preceding a literal or length/distance pair indicates which comes
|
||||
* next, 0 for literals, 1 for length/distance.
|
||||
*
|
||||
* - If literals are uncoded, then the next eight bits are the literal, in the
|
||||
* normal bit order in th stream, i.e. no bit-reversal is needed. Similarly,
|
||||
* no bit reversal is needed for either the length extra bits or the distance
|
||||
* extra bits.
|
||||
*
|
||||
* - Literal bytes are simply written to the output. A length/distance pair is
|
||||
* an instruction to copy previously uncompressed bytes to the output. The
|
||||
* copy is from distance bytes back in the output stream, copying for length
|
||||
* bytes.
|
||||
*
|
||||
* - Distances pointing before the beginning of the output data are not
|
||||
* permitted.
|
||||
*
|
||||
* - Overlapped copies, where the length is greater than the distance, are
|
||||
* allowed and common. For example, a distance of one and a length of 518
|
||||
* simply copies the last byte 518 times. A distance of four and a length of
|
||||
* twelve copies the last four bytes three times. A simple forward copy
|
||||
* ignoring whether the length is greater than the distance or not implements
|
||||
* this correctly.
