Image JPEG Encode (nvm_ijpe_sci)
The NvMedia Image JPEG Encode application, nvm_ijpe_sci,
demonstrates how to encode image surfaces into JPEG bitstreams using NvMedia JPEG encode
APIs. It parses the command line with required parameter sets for JPEG encoder
including:
- Input file name
- Resolution
- Output bitstream file name
- Quality, etc.
It then reads the input file into the image surface and sends the information to the NvMedia JPEG encoder. It saves the resulting bitstreams into a set of output files.
The application also supports CRC generation and CRC checking modes. CRC generation is mainly for developers to provide an original CRC. It can be a different CRC for different Tegra chip versions. CRC checking mode is for QA to verify the application for new releases.
The following diagram describes the basic function flow:
