Rotating RTSP Camera Video with OS X FFmpeg

If you're looking for a way to rotate your RTSP camera video on an OS X system, you've come to the right place. With FFmpeg, a popular command-line tool for video processing, you can easily transcode and rotate your video streams. In this article, we'll explore how to use FFmpeg to rotate your RTSP camera video.

First, let's consider the requirements. You need to ensure that the video stream is captured from your RTSP camera and then rotated by 90 degrees. Since your server is headless without an X display, you're looking for a command-line daemon that can perform this task. Unfortunately, the camera doesn't allow software rotation, so we'll have to rely on FFmpeg to do the trick.

Before we dive into the solution, it's worth noting that there might be some buffering issues (see below) and/or deciding when to terminate the encoding process. However, with FFmpeg, you can easily address these concerns by tweaking the command-line options.

To get started, make sure you have FFmpeg installed on your OS X system. Once you have it set up, you can use the following command to rotate your RTSP camera video:

```

ffmpeg -rtsp_input_location rtsp://camera_ip:554/ -i input.mp4 -vf 'transpose=1' output.mp4

```

In this command:

* `-rtsp_input_location` specifies the location of your RTSP camera stream.

* `-i input.mp4` sets the input file to capture from the RTSP stream.

* `-vf 'transpose=1'` applies the rotation transformation to the video stream. In this case, we're rotating the video by 90 degrees clockwise.

* `output.mp4` specifies the output file for the rotated video.

To run this command as a daemon on your headless server, you can use tools like `launchd` or `cron`. This will allow you to automate the rotation process and ensure that your RTSP camera video is always captured and rotated correctly.

In summary, using FFmpeg on OS X provides a convenient way to rotate your RTSP camera video. With its powerful command-line interface and ability to transcode and manipulate video streams, FFmpeg is an ideal solution for this task. By following the steps outlined in this article, you should be able to get started with rotating your RTSP camera video in no time.
