I am not sure I understand this sentence, but in any
case: There is a png parser but no gif parser, so if
you try to send gifs through a pipe (no matter if
base64 encoded or not), it will not work, sending
pngs through a pipe to FFmpeg is expected to work

Apparently not, at least judging from your report.

You could implement an option to the pipe
protocol to accept (and decode) base64.
Note that a base64 decoder exists in libavutil.
Please fix your quoting and do not top-post;-)
