Quoting you from [1]:
"seriously, example code should be simple and useage of av_free* may not be
for someone unfamiliar with libav* development"

So maybe we should have a similar comment like we have on output-example:
        /* image buffers passed into libswscale can be allocated any
way you prefer,
           as long as they're aligned enough for the architecture, and
           they're freed appropriately (such as using av_free for buffers
           allocated with av_malloc) */
