# General considerations
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.

| -b bitrate | Mandatory option. Sets bitrate with which data should be encoded, in KBits-per-second. Example: -b 5000 to encode data at 5Mbit. |
| -f framerate | Mandatory option. Sets framerate with which data should be encoded in the form -f nominator/denominator. Example: -f 30/1. |

| Argument | Description |
| ------:| -----------:|
| input-file | Mandatory argument. Sets incoming input bitstream to process. Input data should be in raw H.264 format. |
| output-file | Optional argument. Sets raw H.264 video file to write output data. If file will not be specified, tutorial will work in the performance mode: it will process data, but will not produce any output |

Tutorial demonstrates how to transcode given input raw H.264 video stream (input-file) into H.264 stream with different parameters. This tutorial adds VPP processing (x4 down-scaling) in the pipeline. If output-file was specified, produced stream will be written into it. If output-file is omitted, tutorial can be used to estimate constructed pipeline’s performance. Constructed pipeline is configured to share opaque memory between decoder and encoder and work in the asynchronous mode.
