How Do I Determine the Video Stream Format Standard When I Perform CSC on a Model Using AIPP?

Symptom

The video stream format standard failed to be determined when CSC is performed on a model using AIPP.

Solutions

The third-party tool ffprobe is used as an example.

1. Click here to download the tool and related documents.
2. Obtain the video information with the ffprobe -show_frames filename option.

   This parameter displays information about each frame and subtitle contained in the input multimedia stream. The information for each single frame is printed within a dedicated section with name "FRAME" or "SUBTITLE".

3. Determine the video standard based on the result:

   color_range: tv or pc

   color_space: bt709 or bt601

   tv indicates "limited", that is, narrow range. pc indicates "full", that is, wide range.

   For example, color_range=tv and color_space=bt709. The video stream format standard is narrow range, BT.709.

   

   If the command is different from the example, refer to the official description of the tool.
