But in fact, it wasn't possible to convert video to webm format with alpha channel preserved (using ffmpeg/libvpx). Source files definitely contain alpha channel. But no matter which format do I choose in options (yuva420p, rgba and so on), libvpx just forces encoder to pick yuv without alpha.
May you please provide me a hint on how to encode webm with alpha preserved, or are there some other way / codec which may do that?
