Roman Shaposhnik	3c8f30a745	* Restructuring the division of labor between DV codec and DV format [ Based on a patch by Brian Brice (bbrice at newtek dot com) ] Originally committed as revision 6161 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Aurelien Jacobs	75c998a219	force usage of ALT_BITSTREAM_READER where needed Originally committed as revision 6118 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Roman Shaposhnik	56419683b2	I still don't think this should be here. Note: without this code DV encoder will accept incorrect pix_fmt's and such, but decoder will work much better with containers not setting the same attributes. It seems like there will be a generic mechanism for checking such constraints, but if not I can always resurrect this check for encoder only.

Daniel Maas	0b297700b7	DVCPRO50 support. Patch by Daniel Maas dmaas at maasdigital dot com Originally committed as revision 5113 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Roman Shaposhnik	e5867e4d50	Not that we're that far from being an initial implementation, but at least weighting got implemented thanks to Dan. ;-) Originally committed as revision 5071 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Dan Maas	2e52b44e50	AC coefficient weighing (per SMPTE 314M) for the DV encoder and decoder. The performance impact is less than 1%. Patch by Dan Maas (dmaas at maasdigital dot com) Originally committed as revision 5070 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

Michael Niedermayer	d676478c8d	replace for loop with 2 asserts() Originally committed as revision 5066 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago
Dan Maas	6df5f6ae51	size[0-3] are not initialized (and can get random negative trash values), so the comparison with vs_total_ac_bits is messed up on the first couple loop iterations, leading to AC underflows. the b->prev[] pointers were not being maintained correctly. We potentially have to update b->prev[] both before and after the area whose VLC length is getting adjusted. this also might fix the ppc regression failure? patch by (Dan Maas <dmaas maasdigital com>) Originally committed as revision 5064 to svn://svn.ffmpeg.org/ffmpeg/trunk	19 years ago

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

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	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.

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.
