# rtspsrc2
|
|
|
|
|
|
|
|
|
|
Rust rewrite of rtspsrc, with the purpose of fixing the fundamentally broken
|
|
|
|
|
architecture of rtspsrc. There are some major problems with rtspsrc:
|
|
|
|
|
|
|
|
|
|
1. Element states are linked to RTSP states, which causes unfixable glitching
|
|
|
|
|
and issues, especially in shared RTSP media
|
|
|
|
|
2. The command loop is fundamentally broken and buggy, which can cause RTSP
|
|
|
|
|
commands such as `SET_PARAMETER` and `GET_PARAMETER` to be lost
|
|
|
|
|
3. The combination of the above two causes unfixable deadlocks when doing state
|
|
|
|
|
changes due to external factors such as server state, or when seeking
|
|
|
|
|
4. Parsing of untrusted RTSP messages from the network was done in C with the
|
|
|
|
|
`GstRTSPMessage` API.
|
|
|
|
|
5. Parsing of untrusted SDP from the network was done in C with the
|
|
|
|
|
`GstSDPMessage` API
|
|
|
|
|
|
|
|
|
|
## Implemented features
|
|
|
|
|
|
|
|
|
|
* RTSP 1.0 support
|
|
|
|
|
* Lower transports: TCP, UDP, UDP-Multicast
|
|
|
|
|
* RTCP SR and RTCP RR
|
|
|
|
|
* RTCP-based A/V sync
|
|
|
|
|
* Lower transport selection and priority (NEW!)
|
|
|
|
|
- Also supports different lower transports for each SETUP
|
|
|
|
|
|
|
|
|
|
## Missing features
|
|
|
|
|
|
|
|
|
|
Roughly in order of priority:
|
|
|
|
|
|
|
|
|
|
* Credentials support
|
|
|
|
|
* TLS/TCP support
|
|
|
|
|
* NAT hole punching
|
|
|
|
|
* Allow ignoring specific streams (SDP medias)
|
|
|
|
|
- Currently all available source pads must be linked
|
|
|
|
|
* SRTP support
|
|
|
|
|
* HTTP tunnelling
|
|
|
|
|
* Proxy support
|
|
|
|
|
* `GET_PARAMETER` / `SET_PARAMETER`
|
|
|
|
|
* Make TCP connection optional when using UDP transport
|
|
|
|
|
- Or TCP reconnection if UDP has not timed out
|

|
|
|
* Parse more SDP attributes
|
|
|
|
|
- extmap
|
|
|
|
|
- key-mgmt
|
|
|
|
|
- rid
|
|
|
|
|
- rtcp-fb
|
|
|
|
|
- source-filter
|
|
|
|
|
- ssrc
|
2024-01-10 10:10:19 +00:00
|
|
|
* Clock sync support, such as RFC7273
|
|
|
|
|
* PAUSE support with VOD
|
|
|
|
|
* Seeking support with VOD
|
|
|
|
|
* ONVIF backchannel support
|
|
|
|
|
* ONVIF trick mode support
|
|
|
|
|
* RTSP 2 support (no servers exist at present)
|
|
|
|
|
|
|
|
|
|
## Missing configuration properties
|
|
|
|
|
|
|
|
|
|
These are some misc rtspsrc props that haven't been implemented in rtspsrc2
|
|
|
|
|
yet:
|
|
|
|
|
|
|
|
|
|
* latency
|
|
|
|
|
* do-rtx
|
|
|
|
|
* do-rtcp
|
|
|
|
|
* iface
|
|
|
|
|
* user-agent
|
|
|
|
|
|
|
|
|
|
## Maintenance and future cleanup
|
|
|
|
|
|
|
|
|
|
* Test with market RTSP cameras
|
|
|
|
|
- Currently, only live555 and gst-rtsp-server have been tested
|
|
|
|
|
* Add tokio-console and tokio tracing support
|
