Anton Khirnov a84c8af042 FATE: add a test for the ONE_STR mapping mode of the channelmap filter 2014-03-16 07:44:03 +01:00
Anton Khirnov e843612695 af_channelmap: fix ONE_STR mapping mode

Anton Khirnov e854b8f9f4 Work around broken floating point limits on some systems. 
The values of {FLT,DBL}_{MAX,MIN} macros on some systems (older musl
libc, some BSD flavours) are not exactly representable, i.e.
(double)DBL_MAX == DBL_MAX is false
This violates (at least some interpretations of) the C99 standard and
breaks code (e.g. in vf_fps) like
double f = DBL_MAX;
[...]
if (f == DBL_MAX) { // f has not been changed yet
    [....]
}

Anton Khirnov e0ab5078a7 lavc: do not force the emu edge flag 
The default get_buffer2() implementation (and possibly some
user ones) does not allocate edges when this flag is set, which may
expose bugs in some decoders. Until the 10 release is out, it is safer
to remove this part.

Anton Khirnov adb199d1bc kgv1dec: replace forcing EMU_EDGE by a copy 
The decoder currently sets CODEC_FLAG_EMU_EDGE and relies on
get_buffer2() to always provide buffers with linesize == 2 * width.
This is wrong, since we place no such restriction on get_buffer2()
implementations.

Fix this by decoding into internal buffers and copying them to output
frames. Since this is a very obscure decoder, the performance hit should
not be an issue.
