[FFmpeg-devel] [PATCH] Indeo5 decoder
Fri Mar 20 12:13:56 CET 2009
here is a patch for the Intel's indeo video v5 - my recent hard work
within the last year...
For convience the patch includes both "ivi_common.c" and "ivi.common.h"
I posted yesterday (Common code for Indeo interactive)
Samples here: http://samples.mplayerhq.hu/V-codecs/IV50/
Some inital docs here: http://wiki.multimedia.cx/index.php?title=Indeo_4
(will be continually updated, the most of the stuff there is true for
the indeo5 as well)
This decoder must be able to decode the most of IV50 videos. There are
some files out here it won't decode because:
- it was coded using the scalability mode. This mode is unsupported yet,
but I'll add a support for it in the near future.
- the clip was protected using a numeric password. We need to find a way
to decode such a stuff, because indeo5 encrypts the frame data
internally. It's needed to provide either a possibility to input the
correct password or a hack for this. Otherwise such encrypted videos
cannot be decoded properly...
