}}}
so each of them has a difference of 5 just like in your example, the fix
here is to use (see link on patchwork above)
The default value of 1/1000 is good **for most use-cases**, but there
might
be scenarios where it is not (e.g. **TrueHD packets** have a duration <
1ms,
so different packets will **end up with the same timestamp** when using
1/1000). If the user has set a timestamp precision, then that should be
honoured; **but if not, then we might use a different value than 1/1000**
(in the future; I know that currently no code path that makes use of
this exists).
I doubt this will be implemented.
