History

John Koleszar ad252daf65 ivfdec: webm reader support This patch enables ivfdec to decode WebM files. WebM demuxing is provided by the Matthew Gregan's Nestegg library. This patch also makes minor changes to the timebase->framerate handling when doing Y4M output. For WebM files, the framerate is guessed by looking at the first second of video. For IVF files, the timebase=1/(2*fps) hack is still in place, but is only used if the timebase denominator is less than 1000. This is in anticipation of change I8d25b5b, which introduces the distinction between framerate and timebase to ivfenc. In the case of high resolution timebases, like 100ns, we would have to guess the framerate like we do for WebM, but since WebM support in ivfenc will deprecate IVF output, we just assume 30fps rather than writing the lookahead code.

README

halloc 1.2.1
============
      
	Hierarchical memory heap interface - an extension to standard
	malloc/free interface that simplifies tasks of memory disposal 
	when allocated structures exhibit hierarchical properties.

	To build libhalloc.a with GNU tools run
		make

	To install in /usr/include and /usr/lib
		make install

	To cleanup the build files 
		make clean
=
	halloc-1.2.1
		* fixed a double-free bug in _set_allocator() as per
		  Matthew Gregan comments

		* switched to using NULL instead of 0 where applicable

	halloc-1.2.0
		* added missing <string.h> include to halloc.c
		
		* improved standard compliance thanks to the feedback
		  received from Stan Tobias. Two things were fixed -
		  
		- hblock_t structure no longer uses zero-sized 'data'
		  array, which happened to be common, but non-standard
		  extension; 
		  
		- secondly, added the code to test the behaviour of 
		  realloc(ptr, 0). Standard allows it NOT to act as
		  free(), in which case halloc will use its own version
		  of allocator calling free() when neccessary.

	halloc-1.1.0
		* initial public release (rewrite of hhmalloc library)
