When not using the fieldanalysis element immediately upstream of deinterlace, behaviour should remain unchanged. fieldanalysis will set the caps and flags on the buffers such that they can be interpreted and acted upon to produce progressive output. There are two main modes of operation: - Passive pattern locking Passive pattern locking is a non-blocking, low-latency mode of operation that is suitable for close-to-live usage. Initially a telecine stream will be output as variable framerate with naïve timestamp adjustment. With each incoming buffer, an attempt is made to lock onto a pattern. When a lock is obtained, the src pad and output buffer caps will reflect the pattern and timestamps will be accurately interpolated between pattern repeats. This means that initially and at pattern transitions there will be short periods of inaccurate timestamping. - Active pattern locking Active pattern locking is a blocking, high-latency mode of operation that is targeted at use-cases where timestamp accuracy is paramount. Buffers will be queued until enough are present to make a lock. When locked, timestamps will be accurately interpolated between pattern repeats. Orphan fields can be dropped or deinterlaced. If no lock can be obtained, a single field might be pushed through to be deinterlaced. Locking can also be disabled or 'auto' chooses between passive and active locking modes depending on whether upstream is live. |
