Subject: [FFmpeg-devel] [PATCH] adpcm-ima-wav header and codec

94d9633a32 Replace "signed short" typecast with "int16_t" as suggested by 
Mans Rullgard. Value at the right side is 16 bit length signed.
We can not know for sure that short is in fact 16 bits, even if
this virtually always is the case.

0147f19856 beos/mov/adpcm patch by François Revol <revol at free dot fr> 
* Some BeOS fixes:
- errno stuff
- nanosleep() replacement
- added a doc/README.beos

* mov reader still has problems with most videos (skips many chunks),
- It should now read .mov files with zlib-compressed moov headers (aka cmov)
- added SVQ1 support.
- removed mapping 'raw ' and 'yuv2' to h263, was my mistake.
- added IMA4 support. (tested)
- fixed frame rate (it reported 0 fps or something before)
- extended file probing ('wide' and 'free' atoms)
- improved .mov/.mp4 detection (or so I think)

* adpcm
* added zlib support, with header file and lib check
