Description

Every time I try to open a FLV with an Alpha, Quicktime says it doesn't have a plugin for that. All other FLVs open fine.

  • owner changed.
  • component changed from Perian-Main to ffmpeg.

This isn't supported by ffmpeg, whatever codec it is.

FLV_CODECID_VP6A = 5 I'd post it to ffmpeg's issue tracker but that seems to be down right now...

It's now implemented in ffmpeg. See: https://roundup.mplayerhq.hu/roundup/ffmpeg/issue166

  • milestone set to 1.1.1.

I think QuickTime has a YUV+alpha pixel format, but it might be 4:4:4 only. I'm not really interested in writing a fast converter...

The VP6A decoder seems buggy. (it returns silly negative values when there wasn't an error)

  • status changed from new to closed.
  • resolution set to fixed.

(In [876]) Add VP6A, and some associated fixes for it and ZMBV. Might not work until the decoder is fixed in ffmpeg, but closes #237.
