# PeerTube Performances Test Kit
Scripts to generate video files and live streams for performance testing of PeerTube
Scripts to generate video files and live streams for performance testing of PeerTube
## Dependencies
These scripts rely on ffmpeg to generate the videos files and RTMP streams.
Tested with ffmpeg versions:
- 4.1.6
- 4.2.4
# 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 paramters 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-devfined 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
