Is there any way to specify an output fps on decoding? So in other words it

were not interested in receiving every single frame from the decoder.
Just decoding every n-th frame is not possible unless it's an intra
only codec. For other codecs you can try settting skip_frame to
AVDISCARD_NONREF, AVDISCARD_BIDIR or AVDISCARD_NONKEY. How regularly
resulting frames will be depends on the input. All except the first
value might result in incorrectly decoded frames due to missing
references.
