Pi Space-Cam

Records video from the pi camera into h264 format, streams it, and saves it for later

• saves as much video as possible, but when sd card starts to get full deletes oldes video segments

Run

• copy the options.py file into the same directoy as the server scripts
• run python3 main.py

stream

• To stream video move options.py into the same directoy as the streamer_client.py file
• run pyton3 streamer_client.py
• requires vlc

recordings

• I'm working on a bash script to simplify this

• to use the .h264 files run them through ffmpeg ffmpeg -r <record framerate> -i <input h264> -r <record framerate> <output file>

• to concatenate video segments

myfiles.txt
file 'file1.h264'
file 'file2.h264'

ffmpeg -f concat -i myfiles.txt -c copy output.h264

Potential Concerns

• if MIN_FREE_MEM is set too high, there won't be enough records in R_FILE_DIR to delete to create an acceptable amount of free disk
• Current implementation does not allow for different framerates for recording and streaming
• recording must have equal or higher resolution to streaming #TODO: confirm this
• if unix epoch time wraps the memory manager will delete the newest recording segments instead of the oldest
  • a smarted memory managment scheme should be implemented, or the old recording deleted manually if this is a concern
