Consider multiple candidates when searching for audio substream

3

Right now when Sushi searches for audio substream in the destination audio, it only considers the best match, even though OpenCV calculates the diff value for every possible candidate. There...

Custom charset support for subtitles

3

Demux/open/write subtitles with user-specified charset. Something like this should work for FFmpeg (cp1252 example): ``` python args.extend(['-scodec', 'copy', '-sub_charenc', 'cp1252']) ``` And then use `cp1252` while opening the file instead...

Replace mt_merge blending formula

4

As mentioned [here](http://www.vapoursynth.com/2012/11/vapoursynth-tasks/#comment-136), mt_merge uses a slightly incorrect formula. Test script: ``` src = mt_lutspa(expr="x 255 *") mask = mt_lut(y=-255) mt_merge(mt_lut(y=-0), src, mask) mt_lutxy(last, src, "x y - abs 75...

Incorrect error message on y8 input

2

``` c=BlankClip(pixel_type="YV12") c.ConvertToY8().mt_merge(c,c.ConvertToY8(), u=3, v=3, luma=true) ``` Outputs "luma is not supported in 422".

Masktools doesn't complain if mt_merge is called with RGB mask and just crashes at runtime. Fix this.

Write a new signal library

1

``` signal_expr2( c1.signal_getvalue("avg"), c2.signal_getvalue("med"), "x y + whatever" ).signal_setvalue(last) ``` After 16-bit support is implemented in masktools, add a new signal library based on the same common shared lib. Each...

Optimized version of mt_lutxy("x y - abs"). Request by torchlight.

Actually this should be allowed if chroma planes are in NONE mode but it might be a pain to implement. Anyway we should at least print some reasonable error message...
