Transcoding Benchmark for Simultaneous AVC-AVC Transcodes

This test attempts to extract the maximum number of simultaneous AVC transcodes while maintaining a
minimum of 30 FPS using Intel® Media Server Studio and a web-available video sample.
 Target: Most number of simultaneous AVC transcodes achieved while keeping 30 FPS (real-time)
 Test configuration: 2x Intel VCA 2 with all 6 nodes running simultaneous transcoding
 Environment: Bare metal, non-persistent image
 Transcoding software: Intel Media Server Studio 2017 (available at
en-us/intel-media-server-studio)
 Input file: blue_sky_1080p25_3min.h264 (available at
test_sequences/1080p/)
 PAR file details:
-async 3 -hw -u 7 -cqp -qpi 24 -qpp 26 -qpb 28 -gop_size 61 -dist 3 -i::h264
/input/blue_sky_1080p25_3min_18.h264 -o::h264 /dev/null
 Results: See Table 9

Temperature Profile

The temperature while booted in idle mode is ~35 °C. Temperature during workload is expected to reach
~60 °C. During transcoding workload, the script runs the load twice to ensure frame rate achieved is correct,
hence the temperature curve between runs is expected.
