Re: How to provide data to RTSPClient wihout latency? [appsrc, buffering]

Hi Michael,

AppSrc ignores max-buffers and max-time, it just issues a warning and 
continues buffering. Maybe it is intentional, or perhaps it is because 
gst_base_src_loop is blocked, waiting for a reply from 
gst_pad_peer_query. Leaky-type leads to a jerky, stuttering video. 
is_live is already set to true.

The scenario of events looks fundamentally wrong. So, I want to 
understand what is going on.

Andrey.

For example `appsrc max-buffers=3 leaky-type=downstream` will only keep the latest 3 camera buffers and discard older ones. Also, if your buffers come from a camera set the `is-live=true` property as well. If I recall correctly, that'll let the pipeline know you're pushing data from a live source and will not perform this delay (don't quote me on that :) ). An initial PTS of 1000 hours is expected in video encoders, and is to allow reordering of frames where the first DTS can be lower than the first PTS.
