[FFmpeg-devel] How to pass metadata between filters

[Mujib Haider]

Dear ffmpeg-devel,

I have a general question about the capabilities of avfilter.

Is it possible to send meta-data between avfilters? Specifically, I want to create a filter to take a single input image, and produce a single output image along with metadata which encodes information about the image.

Sincerely,
Mujib
