Make avfilter_start_frame() invoke avfilter_get_video_buffer() on the

link rather than avfilter_default_get_video_buffer().
This is required as the buffer requested may be greater than the
buffer allocated locally by avfilter_default_get_video_buffer(), for
example if in filterchain there is a pad filter (like in "fifo,pad").
In that case the pad filter will try to write beyond the data of the
allocated buffer, resulting in a crash.

Fix the size of the data to be copied from an AVFilterBuffer to an
...
AVFilterBuffereRef in avfilter_default_get_video_buffer().
The error was being caused by the previous patch which resized
AVFilterBuffer's data and linesize arrays to 8.

Generalize pixel format enum fields to int formats.
...
This is needed to make the libavfilter framework work with audio
filters.
In particular add a type field to AVFilterLink, change the field types:
enum PixelFormat format -> int format in AVFilterBuffer
enum PixelFormat *formats -> int *formats in AVFilterFormats
enum PixelFormat *format -> int format in AVFilterLink
and change the function signatures:
AVFilterFormats *avfilter_make_format_list(const enum PixelFormat *pix_fmts); ->
AVFilterFormats *avfilter_make_format_list(const int *fmts);
int avfilter_add_colorspace(AVFilterFormats **avff, enum PixelFormat pix_fmt); ->
int avfilter_add_format(AVFilterFormats **avff, int fmt);
AVFilterFormats *avfilter_all_colorspaces(void); ->
AVFilterFormats *avfilter_all_formats(enum AVMediaType type);
This change breaks libavfilter API/ABI.

byte position information, as stored in the pkt.pos, through the

Note that the pos field is added *non* at the end of the
AVFilterPicRef struct, thus breaking ABI compatibility, which is
allowed as the API is still considered non-stable.

Extend the slice filter to make it issue slice height values randomly
...
choosen between 8 and 32 when the supplied parameter is the string
"random".
This is useful for testing the slice support, but it is not supposed
to be used for other purposes and this interface may change in the
future, thus it is not documented.
The randomization algorithm adopted is the standard Numerical Recipes
LCG.
