how to set property for Appsrc?

[Soho Soho123]

Hi Stefan,

Do you have idea about max-bytes, min-latency, max-latency properties?
I do not know which value of min-latency, max-latency is suitable for
reducing latency?
Do you know where is the example about the usage?
If I set smaller for max-bytes, can it reduce latency?
Thanks!
Soho
