event_loop Subscribe error: no app or stream name

[fgadaleta]

In my scenario OBS is streaming to rtmp://127.0.0.1:1935/live/test And connection is correctly established

My config.toml is simply

[rtmp]
enabled = true
port = 1935

# pull streams from other server node.
[rtmp.pull]
enabled = false
address = "localhost"
port = 1935

[httpflv]
# true or false to enable or disable the feature
enabled = true
# listening port
port = 8081

[hls]
# true or false to enable or disable the feature
enabled = true
# listening port
port = 8080

But when I play the stream with any of the two below

ffplay -i rtmp://localhost:1935/live/test
ffplay -i http://localhost:8081/live/test.flv

I get 2 errors. One server side

event_loop Subscribe error: no app or stream name

and one client side

ffplay -i http://localhost:8081/live/test.flv

Could you show me your OBS configuration GUI? I guess that your pushing configuration for RTMP app name and stream name are not "live" and "test"??

[fgadaleta]

they seem to be In OBS I set the server as rtmp://127.0.0.1:1935/live/test with an empty Stream key

[harlanc]

The server should be rtmp://127.0.0.1:1935/live and the stream key should be configured as test

[fgadaleta]

ok it works now thanks! Just with a delay of ~5 secs (both OBS and the server are running locally)

Both compiled debug and release (still the 5 sec lag)

[harlanc]

The latency is related to the push client GOP size and the play client buffer size.

The latency is related to the push client GOP size and the play client buffer size.

I have OBS set as low-latency encoder settings (3000kbs) and I am playing with ffplay -i http://localhost:8081/live/test.flv

[harlanc]

What about your rtmp stream latency？try to add the “-fflags nobuffer” parameter for ffplay

[fgadaleta]

What's about your rtmp stream latency？try to add the “-fflags nobuffer” parameter for ffplay

even worse

[harlanc]

Did the ffplay print errors or warnings？

[fgadaleta]

Actually yes I get this in red

[h264 @ 0x7f806899e3c0] co located POCs unavailable
[h264 @ 0x7f8068b68380] co located POCs unavailable

[harlanc]

Now the default RTMP implemantation will cache 1 GOP which may increase the latency. I will do some improvements in the future to add this as a configuration.Then you can control to open the cache or not yourself.

[fgadaleta]

That would be a great fix indeed

Thank you
