I'd remove this, before it stays there for years.

This macro seems very silly. Better do:
struct type var = {0};
....
var = (struct type){0};

Might make sense to move them to the start, so that positional filter
arguments work? (I don't know.)

Uh, what do b_frames do outside of the decoder? Filters always get
frames in display order. This makes no sense to me.

Well, I hope this doesn't over-read the input AVFrames if the AVFrames
are not aligned. Some AVFrames might still be padded (if they're output
by a decoder which does so), but you can't rely on this.

Generally, all of these occurrences should be replaced with proper
ffmpeg-style error codes and error checks. Use AVERROR(ENOMEM), and use
"err < 0" as check whether a function failed. Make it consistent,
because the current state is confusing.
