Function ffav_sys::avcodec_receive_packet

pub unsafe extern "C" fn avcodec_receive_packet(
    avctx: *mut AVCodecContext, 
    avpkt: *mut AVPacket
) -> c_int

Read encoded data from the encoder.

@param avctx codec context @param avpkt This will be set to a reference-counted packet allocated by the encoder. Note that the function will always call av_frame_unref(frame) before doing anything else. @return 0 on success, otherwise negative error code: AVERROR(EAGAIN): output is not available in the current state - user must try to send input AVERROR_EOF: the encoder has been fully flushed, and there will be no more output packets AVERROR(EINVAL): codec not opened, or it is an encoder other errors: legitimate decoding errors
