Michael Niedermayer	7e068841cb	replace long double in the audiophile kiddy mode with doubles, its faster (and more portable) and the audiophile placebo 120db stopband attenuation isnt affected Originally committed as revision 8482 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Michael Niedermayer	d6fead9089	change high precision mode to 30 bits again after making the code less overflow sensitive Originally committed as revision 8481 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago

Michael Niedermayer	66a148a19a	remove dithering of filter coefficients, improves precision by 1-2 bits and improves subjective sound quality on artificial sample (udial.wav resampling to 32khz) Originally committed as revision 8467 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
David Conrad	8076609a40	The NSV demuxer assumes that a video frame's timestamp increases by one on each frame, but some low-bitrate NSV files omit video frames for some NSV frames, and expect the timestamp to increase by one every NSV frame. This is noticeable in 64vp3.nsv where the video runs several times faster than the audio. Fix this by unconditionally incrementing the video's timestamp with each NSV frame. patch by David Conrad, umovimus gmail com Originally committed as revision 8466 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Wolfram Gloger	df7625ed62	av_estimate_timings_from_pts() flushes the packet queue but doesn't reset the streams' cur_dts values. This can lead to a fatal "error, non monotone timestamps ..." message later, because the out-of-date cur_dts values are used to compute some packet's dts. Fix this by calling av_read_frame_flush() and eliminate code duplication in the process. The additional hunk gives more detailed error messages. patch by Wolfram Gloger, wmglo dent.med.uni-muenchen de Originally committed as revision 8465 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
