===Pipe to stdout=== | |||
Below is an example of piping the video only to stdout: | |||
<pre> | |||
ffmpeg -i video.webm -pix_fmt rgb24 -f rawvideo - | |||
</pre> | |||
In Python, you can read it as follows: | |||
<syntaxhighlight lang="python"> | |||
ffmpeg_process = subprocess.Popen(ffmpeg_command, | |||
stdout=subprocess.PIPE, | |||
stderr=subprocess.PIPE) | |||
raw_image = ffmpeg_process.stdout.read( | |||
video_width * video_height * 3) | |||
image = (np.frombuffer(raw_image, dtype=np.uint8) | |||
.reshape(video_height, video_width, 3)) | |||
</syntaxhighlight> | |||
