I am running this command to get two images per second from an rtsp stream:
const ffmpeg = spawn(this.ffmpeg, [
// Set the frame rate of the input video to 2 frames per second
'-r',
'2',
// Specify that the RTSP stream should use TCP as the transport protocol
'-rtsp_transport',
'tcp',
// Set the input source to the RTSP stream specified by the `rtspUrl` variable
'-i',
rtspUrl,
// Set the video filter to only output two frames per second (final video)
'-vf',
'fps=2',
// Set the output format to "image2pipe," which specifies that the output should be written to stdout as a series of images in a pipe
'-f',
'image2pipe',
// Overwrite any existing output file without prompting for confirmation
'-y',
// Set the output destination to stdout
'-',
]);
I am subscribing to the stdout and saving each emit into a file (just for testing, I need to process the data later)
let i = 0;
from(ffmpeg.stdout)
.pipe(
concatMap((data) => {
i++
return writeFile(`file_${i}`, data).then(() => i);
}),
)
.subscribe((i) => {
this.imageLogger.log(`file_${i} saved`);
});
The thing is, I am getting a lot more than 2 images per second:

Am I missing some part? why I do not only get 2 stdout events pro second?
ffmpeg version 5.0.1-static node: 18.12.1
When I run this command on the terminal:
ffmpeg -r 2 -rtsp_transport tcp -i "rtsp://user:[email protected]:554/stream2" -vf fps=2 -timecode 00:00:00:00 test.mp4
The generated video has a frame rate of 2 but it looks like it is in slow motion. Since the source video has also a timer, I see how it takes something like 12 "frames" to go from one second to another.
This is the output:
