Well, for kicks, I asked ChatGPT 4 if you can add GPS metadata to a MP4 file. Here is the conversation:
Me
Can I use ffmpeg to add geo location to mp4 files?

Yes, you can use FFmpeg to add geolocation metadata to MP4 files. Geolocation data is typically embedded in the metadata of a file in the form of GPS coordinates. To do this with FFmpeg, you would use the -metadata option to add custom metadata fields to your video file.
Here is a general approach to add GPS metadata using FFmpeg:
Determine the GPS Metadata Format: First, you need to know the correct format for embedding GPS data. This often follows a specific string format, such as GPSLatitude=xx.xxxx,GPSLongitude=yy.yyyy.
Use FFmpeg to Add Metadata: You can add this metadata using FFmpeg with a command similar to the following:
bash
ffmpeg -i input.mp4 -metadata "metadata_key=metadata_value" -codec copy output.mp4
Replace metadata_key with the appropriate key for GPS metadata (like location, GPSLatitude, GPSLongitude, etc.) and metadata_value with the actual GPS data.
For example:
bash
ffmpeg -i input.mp4 -metadata "GPSLatitude=35.6895" -metadata "GPSLongitude=139.6917" -codec copy output.mp4
This command will add GPS metadata to output.mp4 without re-encoding the video, thus preserving its original quality.
Check Metadata Format Compatibility: Be aware that the format for GPS metadata can vary depending on the playback system or standard you're targeting. You should verify the correct format for your specific needs.
Remember, the effectiveness of this metadata embedding can depend on how the player or platform reading the file interprets metadata. Not all players or platforms may recognize or use this metadata. Also, ensure that the GPS coordinates are in the correct format and are accurately representing the location you intend to embed. |
