Pass ffmpeg stream through python script
Please tell me how to pass my stream from ffmepg through python script, get response back, and pass it to ffmpeg again? For now i have something like this:
FFMPEG_SCRIPT = [ "ffmpeg", '-i', 'fifo', '-pix_fmt', 'bgr24', '
-vcodec', 'rawvideo', '-an', '-sn', '-f', 'mpegts', '-' ]
pipe = sp.Popen(FFMPEG_SCRIPT, stdout = sp.PIPE, bufsize=4096)
After this i'm just reading video-frames in while loop
while True:
frame = pipe.stdout.read(480*720*3)
sys.stdout.write(frame)
So how can i access the frame after i wrote it to stdout at the last line?
