  Changed paths:
    M src/modules/avformat/consumer_avformat.c

  Log Message:
  -----------
  Add alpha channel support to avformat consumer.

This requires that you set the pix_fmt property correctly for the codec:
  vcodec=png pix_fmt=rgba
  vcodec=targa pix_fmt=bgra
  vcodec=qtrle pix_fmt=argb

Sometimes you also need to use mlt_image_format=rgb24a to prevent losing
the alpha channel during image processing.
