go-mp4 is Go library and CLI tool which provide low-level I/O interfaces of MP4.
go-mp4 is Go library which provides low-level I/O interfaces of MP4.
This library supports you to parse or build any MP4 boxes(atoms) directly.
go-mp4 provides very flexible interfaces for reading boxes.
If you want to read only specific parts of MP4 file, this library extracts those boxes via io.ReadSeeker interface.
On the other hand, this library is not suitable for complex data conversions.
## Integration with your Go application
### Reading
