Dear FFMPEG users and developers,

I followed this
<https://gist.github.com/VCone/266ff5c7ce2c3ac7a64d8017125f8b0c> to bring a
stdinput into FFMPEG.

The idea is: we use AS3 to capture every frame in Animate to byteArray
(with ARGB pixel format - means the frame can have transparancy
background). After that, we transfer that byteArray into FFMPEG to get
output.

If I capture a non-transparency picture motion (the picture with
background), the process works well to create a motion video.

But when I capture transparency pictures and make motion (multi-frame
video), the problem appears as below:

We can see the bird print a long streak, but I expect one bird flying from
the right to the left like this.

It seems like the previous frames are not cleared.

Do you have any suggestions to solve this?

Best regards,
N Phat from Vietnam
