Techniques are generally described for catch-up pacing for video streaming. In various examples, a camera may capture first video data representing a physical environment. In some examples, motion in the physical environment may be detected from the first video data. A communication channel may be established with a remote computing device. In some examples, the camera may capture second video data. In various examples, the second video data may be captured during a period of time corresponding to the establishment of the communication channel. An available bandwidth of the communication channel may be determined. The available bandwidth may comprise a first bitrate. Third video data may be captured by the camera. The third video data may be encoded at a second bitrate lower than the first bitrate. The first video data, second video data and third video data may be sent to the remote computing device.

Catch-up pacing for video streaming

Techniques are generally described for bit rate stabilization. In various examples, an encoder may identify a first frame of video data to be encoded using a first quantization value. In some examples, the encoder may determine an estimated compressed frame size of the first frame encoded using the first quantization value. In various examples, the encoder may determine that the estimated compressed frame size is less than threshold size. The encoder may further determine a second quantization value that may be less than the first quantization value. The encoder may generate a compressed first frame of video data using the second quantization value and the first frame of video data. The compressed first frame may be sent to a recipient computing device.
