Callback for video frames

API description

public void onReceiveFrameYUVData(int sessionId, ByteBuffer y, ByteBuffer u, ByteBuffer v, int width, int height, int nFrameRate, int nIsKeyFrame, long timestamp, long nProgress, long nDuration, Object camera);

Parameters

Parameter Description
sessionId The session ID.
Y The luma (Y’) information of video streams.
u The chroma (U) channel information of video streams.
v The chroma (V) channel information of video streams.
width The width of video images.
height The height of video images.
nFrameRate The frame rate of video streams.
nIsKeyFrame Indicates whether a keyframe or an I-frame is used.
timestamp The timestamp.
nProgress The playback progress of the video pushed by the Message Center module.
nDuration The duration of the video pushed by the Message Center module.
camera The IPC that collects video footage.

Only nProgress and nDuration are required for video playback.

Navigate from alerts to SD card-stored content

By default, alerts are generated independently from playback of SD card-stored content. In certain conditions, video recording and alert triggering might occur at the same time.

  • During SD card-stored video recording, alerts and video footage can be simultaneously generated by the same triggers. Specifically, they have the following differences:

    • Alerts are stored in the cloud.
    • SD card-stored video footage is stored on an IPC. If the SD card capacity is insufficient, the earlier video footage might be overwritten by later footage.
  • The switch for SD card-stored video recording is set independently from the switch for detection alerts. Therefore, during SD card-stored video recording, alerts do not always trigger video recording.

    In certain cases, alerts can be linked with video footage stored on the SD card. The IPC SDK does not provide a typical API method to query video footage based on this type of correlation. However, to find the video footage triggered by alerts, users can find the time and date when the alerts were generated. Then, check whether the target video footage was created on this date. You can implement navigation from alerts to SD card-stored video footage in this way.
