This PR:

• adds discontinuity field to the MPEG.TS.PES packets created from a given input buffer, based on the value passed to the push_buffer function along that buffer

Hi @varsill! This is great, the integration with events done on the plugin as well looks way better now. As soon as you're still working on this discontinuity thing, could you please write a test case? Ideally a ts file in test/fixtures and the full processing of it!

If it is easier for you we might just add it to the plugin!

Hello, sure, I will do that!

I will add it to the membrane_mpeg_ts_plugin then, I think such a test will cover more parts of the code. [EDIT] I think it might be better to add test in both places ;)

Thanks @varsill!
