| AVRational FilterLink::frame_rate |
Frame rate of the stream on the link, or 1/0 if unknown or variable.
May be set by the link source filter in its config_props(); if left to 0/0, will be automatically copied from the first input of the source filter if it exists.
Sources should set it to the best estimation of the real frame rate. If the source frame rate is unknown or variable, set this to 1/0. Filters should update it if necessary depending on their function. Sinks can use it to set a default output frame rate. It is similar to the r_frame_rate field in AVStream.
