The current impementation of early frame drops (dropping frames before adding them to the picture queue) has multiple problems: Even after gettin A-V sync, the frame droping continues until VideoState->skip_frames reaches 1, which can take a lot of time causing useless additional frame drops and bad AV-sync. This issue can be easily triggered with for example changing the audio stream. Also video_refresh currenly does not handle early skipped frames in every case, for example if we skip a frame, then the last frame duration calculation will compute the duration of the sum of the skipped frame and the duration of the frame before that, and in compute_target_delay we may multiply this unusually big delay.
