PeerTube Performances Test Kit

Scripts to generate video files and live streams for performance testing of PeerTube

Dependencies

These scripts rely on :

• ffmpeg to generate the audio/video streams. Tested with ffmpeg versions:
  • 4.1.6
  • 4.2.4
• bc to compute the encoding buffer size from the specified video bitrate

To install the dependencies on Debian 10 (Buster):
sudo apt install ffmpeg bc

Mains scripts

There are 4 main scripts :

• gen_pattern_sine.sh
  generate video file with static pattern, time overlay (seconds elapsed from start) and sine wave stereo audio
• gen_random_noise.sh
  generate video file with random video, time overlay (seconds elapsed from start and local timestamp) and sine wave stereo audio
• stream_pattern_sine.sh
  send live stream and save a copy to file with static pattern, time overlay (seconds from start) and sine wave audio
• stream_random_noise.sh
  send live stream and save a copy to file with random video, time overlay (seconds elapsed from start and local timestamp) and sine wave audio

Run the scripts with no parameter for help.

The "random_noise" scripts are designed to produce video streams that are very hard to encode. These are to test worst case scenarii

The "pattern_sine" scripts produce video streams that are lighter to process (use less CPU to encode on peertube side) and compress to a smaller size.

Helper scripts

The other scripts are helpers that are just sortcuts to call the main scripts with some pre-defined parameters values. The names of these scripts should be self explanatory :

• gen_pattern_1080p_60s.sh
• gen_pattern_720p_60s.sh
• gen_random_1080p_60s.sh
• gen_random_720p_60s.sh
• stream_pattern_1080p_300s.sh
• stream_pattern_1080p_3600s.sh
• stream_pattern_720p_300s.sh
• stream_pattern_720p_3600s.sh
• stream_random_1080p_300s.sh
• stream_random_1080p_3600s.sh
• stream_random_720p_300s.sh
• stream_random_720p_3600s.sh
