Hap_q_alpha is it possible?

Alex Ramos
Hello,
I think I'm missing something.
ffmpeg -i source.mov -vcodec hap -format hap target.mov OK
ffmpeg -i source.mov -vcodec hap -format hap_alpha target.mov OK
ffmpeg -i source.mov -vcodec hap -format hap_q target.mov OK
This is not working, what's switch for Hap Q Alpha ?
ffmpeg -i source.mov -vcodec hap -format hap_q_alpha target.mov

I'm on win7
Thanks
Alex

HapQ Alpha encoding is not yet implemented in FFmpeg.
(Only decoding for now)
