[FFmpeg-user] ffmpeg architecture question

[Mark Filipak]

Another revealing example:

"split[A][B],[A]select='eq(mod((n+1)\,5)\,3)'[C],[B]datascope,null[D],interleave"

Though the [B][D] branch passes every frame that is presented at [B], datascope does not appear for 
frames 2 7 12 17 etc.

That reveals that traversal of ffmpeg filter complexes is not recursive.

Do you agree, Paul, or am I mistaken?
