PCM files larger than 4GB are not indexed by WAVSource

[FranceBB]

Hi there,
I noticed an issue with PCM files larger than 4GB.
Basically, if you have a PCM file larger than 4GB saved as .wav and you try to index it using WAVSource, it won't index it.
I think that this is related to the fact that WAVSource only supports the old WAV container and not w64 nor rf64.

To reproduce this:

p1=ColorBars(848, 480, pixel_type="YV24")
p2=ColorBars(848, 480, pixel_type="YV24")
p1++p2

ch1=GetChannel(1)
ch2=GetChannel(2)
MergeChannels(ch1, ch2, ch1, ch2, ch1, ch2, ch1, ch2, ch1, ch2, ch1, ch2, ch1, ch2, ch1, ch2)

save as .wav on VirtualDub.

Then try to index it in Avisynth:

video=BlankClip(length=215783)
audio=WAVSource("Y:\00_INGEST_MAM\Colorbars.wav")
AudioDub(video, audio)

Will result in:

AVIFileSource: Couldn't open file


On the other hand, using BestAudioSource() works:

video=BlankClip(length=215783)
audio=BestAudioSource("Y:\00_INGEST_MAM\Colorbars.wav")
AudioDub(video, audio)


So... is w64 and rf64 support going to be added to WAVSource() in Avisynth+?
