- General considerations
- Basic tutorials
- Decoding tutorials
- Encoding tutorials
- Video PreProcessing (VPP) tutorials
- Transcoding tutorials
Intel Media SDK Tutorials package was designed in the simplistic manner. Each tutorial suites the purpose to demonstrate some technique of working with the Media SDK library. For the simplicity sample code supports only minimum required number of options without which it is impossible to variate input data and produce correct result. This command line reference is divided into few parts. Each part describes group of tutorials which have the same or similar list of command line options and arguments. The parts are:
- Basic tutorials.
- Decoding tutorials. The only configurable component in these tutorials is decoder (H.264). Configuration parameters are input and output streams.
- Encoding tutorials. The only configurable component is encoder (H.264). Configuration parameters (besides input and output stream) - width, height, bitrate, framerate.
- VPP tutorials. The only configurable component is VPP. Configuration parameters (besides input and output stream) - input stream width and height.
- Transcoding tutorials. Configurable components are decoder (H.264) and encoder (H.264). Configuration parameters are: input/output streams, bitrate/framerate to encode.
simple_1_session [-sw | -hw | -auto] Tutorial initializes Intel Media SDK session of a specified type. If -auto is specified (the default) Media SDK dispatcher will automatically select library implementation to use. If -hw is specified HW implementation will be used, -sw - SW one. Depending on Media SDK distribution different implementations may present. Options to adjust session type are applicable for all other tutorials described in this reference.
