The next 420x360x3 bytes afer that will represent the second frame, etc. If the video has a size of 420x320 pixels, then the first 420x360x3 bytes outputed byįFMPEG will give the RGB values of the pixels of the first frame, line by line, top to bottom. and install ffmpeg-python again with : pip install ffmpeg-python. First, right click This PC (Windows 10) or Computer (Windows 7) then click Properties > Advanced System Settings > Advanced tab > Environment Variables. exe in cmd you have to tell your computer where it can find it. uninstall both with: pip uninstall ffmpeg pip uninstall ffmpeg-python. Vscode python no such file or directory Before you can use ffmpeg. 2>&1 your-process where your process will gets the data to stdin. Im guessing this happens if youve installed both, ffmpeg and ffmpeg-python. Now we just have to read the output of FFMPEG. to redirect the output of ffmpeg to be the input of your process use the following: ffmpeg -i inputfile. It can be omitted most of the time in Python 2 but not in Python 3 where its default value is pretty small. In sp.Popen, the bufsize parameter must be bigger than the size of one frame (see below). The format image2pipe and the - at the end tell FFMPEG that it is being used with a pipe by another program. In the code above -i myHolidays.mp4 indicates the input file, while rawvideo/rgb24 asks for a raw RGB output. Import subprocess as sp command = pipe = sp.
