Roman Shaposhnik	aa06658248	Moving dv_anchor back to the global scope. This creates a tiny memory leak for cases like dlopening libavcodec.so and such, but I still don't know how to catch such events. Originally committed as revision 4818 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	eea8c08fa8	cleanup & memleak fix Originally committed as revision 3095 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Roman Shaposhnik	901ee2bea3	* some significant clean-up of the dv_decode_ac (it looks real simple now, take a look for yourself). * additional optimizations of the decoder. It runs at 55fps now on my desktop and it used to be ~45fps. Originally committed as revision 2926 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago

Roman Shaposhnik	380fd6b1b4	* DV decoder simplifications. Now it looks to be 6% faster. At least on my desktop. * Misc. DV cleanups and fixes. Originally committed as revision 2892 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago
Roman Shaposhnik	e7a18d5deb	* moving some of the commonly used bit reading/writing functions from common.c -> common.h so that they can be inlined. + performace gain ~1% (measured with DV decoding) + code bloat 0.05% Looks like a win-win solution. Originally committed as revision 2874 to svn://svn.ffmpeg.org/ffmpeg/trunk	21 years ago

Roman Shaposhnik	e15c330246	* 3x encoding speedup. Finally we seem to be on par with libdv in terms of time and we're doing slightly better w.r.t. to quality. I don't think there's much room for improvement left, but I'd like to try and vectorize a couple of things. Btw, any ideas on what may impact performance will be greatly appreciated.

Roman Shaposhnik	10acc47995	* introducing dct248 into the DSP context. * simple/accurate implementation of dct248 * DV encoding now supports 2-4-8 DCT * DV encoding gets a bit faster (but still miles away from what I think it could do) * misc.

Roman Shaposhnik	4fa1c4fa8d	* preAlpha DV encoding support -- there's still a truckload of work to do, but it least people can try it out and share ideas. Please don't hesitate to give it a spin: $ ffmpeg -i file.avi file.dv is all you need. * fix for a deallocation bug in DV muxer Originally committed as revision 2327 to svn://svn.ffmpeg.org/ffmpeg/trunk	22 years ago
Roman Shaposhnik	7458ccbb02	* DV handling was streamlined for both muxing/demuxing and decoding. All muxing/demuxing functionality is now available in libavformat/dv.[ch]. * dv1394.c and avidec.c were hooked up with general DV demuxer. * DVAUDIO is dead! Long live pcm_s16le! * DV audio is now always recognized -- which means we can now hear all those ducks quaking in pond.dv.
