ReadWriteEDID

Supported Hardware Devices: Pro/USB Capture devices supporting HDMI signals

Contents Demonstrated in the Sample:

1. Export EDID from a specified channel to a binary file
2. Import a binary file (EDID) from a specified path and write it to a specified channel

Call Logic:

1. Obtain version information, initialize, and enumerate devices: MWGetVersion, MWCaptureInitInstance, MWRefreshDevice, MWGetChannelCount
2. Open the device:
   1. Open the device specified by command parameters: MWOpenChannel
   2. When no device is specified in command parameters, open the first available channel by default: MWGetDevicePath, MWOpenChannelByPath
3. Retrieve channel information and filter devices: MWGetChannelInfo, MWGetVideoInputSource, MWGetAudioInputSource
4. Determine based on command parameters whether to export the current channel information to a binary file or import binary file information and write it to the current channel:
   1. Save EDID information from the specified channel to a binary file:
      1. Retrieve EDID information: MWGetEDID
      2. Write to binary file
   2. Read binary file information and write to the specified channel:
      1. Read binary file: fread
      2. Write EDID to current channel: MWSetEDID
5. Release resources: MWCloseChannel, MWCaptureExitInstance
