The driver fills in both the struct v4l2_capability driver and card fields the same values, that is the driver's name plus the information if the dev is a decoder or an encoder.But the driver field has a fixed length of 16 bytes so the filled data is truncated: Driver Info (not using libv4l2): Driver name : s5p-jpeg decode Card type : s5p-jpeg decoder Bus info : platform:11f50000.jpeg Driver version: 4.7.0 Also, this field should only contain the driver's name so use just that. The information if the device is a decoder or an encoder is in the card type field anyways.
