Changes to 2.53 Released
- Added Overlay() for doing advanced video overlays/layers. See avisynth.org for documentaion.
- Added SuperEQ by Naoki Shibata. Further documentation atavisynth.org.
- EMMS is now executed between all filters to avoid potential FPU-states to be carried from one filter to the next.
- Better seeking precision in audio in DirectShowSource.
- Internal audio cache now has better efficiency.
- German documentation temporarily not included (being restructured).
- Reimplemented SSRC. It is now capable of running multiple instances, it has been better tested (occational strange sample should be eliminated). This version support both upsampling and downsampling with very high precision.
- Added fast=true/false mode to SSRC. This will use a faster mode for resampling. Default is false.
- Added internal audiocache by WarpEnterprises. Added automatically by the filters that need it.
- Fixed crashes and Audio corruption in ConvertToMono().
- Added IsYUV(clip) to script (it was only present in the documentation).
- If any filter should request audio that is out of bounds, if will no longer be passed to the filter above, but the invalid parts will be filled with silence.
- Documentation restructured and much has been updated!
- Added Histogram(mode="stereo") shows a clasic stereo graph (I guess) from the audio in the clip. Some may know these from recording studios. Quite nice actually.
- Added linear=true/false to changefps. this will make AviSynth request frames in a linear fashion, when skipping frames. Default:true.
- Added mode="stereooverlay". Draws the stereograph on top of the original image. YV12 only.
- Fixed green bars in small video with mode="levels" and mode="color".
- Added C-versions of conditional planedifference filters, for non-ISSE machines (not well tested though).
- Added SSRC resampling. Usage: SSRC(int samplerate). Note that it only downsamples. Audio is always converted to float.
- Added Tone(float length, float frequency, int samplerate, int channels, string type). This will generate sound.
- - Length is in seconds. Type can be "Silence", "Sine" (default), "Noise", "Square", "Triangle" or "Sawtooth".
- - Defaults are Tone(10.0, 440, 48000, 2, "sine").
- Fixed Unalignedsplice if only audio was present.
- Fixed Trim crash, if only audio was present (throws an error).
- Optimization: MMX in Dissolve.
- Fixed slowdown on multiple Directshow Sources.
