50  * This tries to test video encoder / decoder performance by running encoding / decoding
51  * without displaying the raw data. To make things simpler, encoder is used to encode synthetic
52  * data and decoder is used to decode the encoded video. This approach does not work where
53  * there is only decoder. Performance index is total time taken for encoding and decoding
54  * the whole frames.
55  * To prevent sacrificing quality for faster encoding / decoding, randomly selected pixels are
56  * compared with the original image. As the pixel comparison can slow down the decoding process,
57  * only some randomly selected pixels are compared. As there can be only one performance index,
58  * error above certain threshold in pixel value will be treated as an error.
