SAT>IP Error

[BladeMSR]

Hi everybody,

this is my first post so I just want to introduce myself. My Name is Joachim and I am living in Germany. I am using the VLC Software on different platforms now for more then 6 months. Everything worked fine, but after the update to VLC for Mobile 2.7.1 I get an error when I try to open an SAT>IP stream.

Your input can't be opened
VLC is unable to open the MRL 'http://xxx.xxx.xx.xx/dlna/?type=DVB-S-A ... 1,3327,108'.
Check the log for details.

Where do I find the log File or what can I do?

On my MAC Book I am using the Version 2.2.1 which is still working fine

libvlc 3.0, which is used by VLC for iOS these days, no longer accepts SAT>IP URLs with the "rtsp" protocol because the SAT>IP spec is very far from standard compliant rtsp and specifying http as the protocol worked out of pure luck I fear. However, this should work : satip://xxx.xxx.xx.xx/dlna/?type=DVB-S-AUTO&src=1&freq=12480&pol=v&sr=27500&pids=0,3327,3328,8191,3327,108

I didn't test on iOS myself, but on OS X, this works with anything newer than early Dec.

Hallo Felix,

thank you for the quick answer. I tried it with your suggested URL, but it won't help. Maybe I didn't got the point. The SAT>IP source is a UPnP Server from SCHWAIGER (MS41IP). VLC finds the source, offers me Channels but when I select on of the programs the error occurs. The mentioned LOG File can I find where?

The log file is not exposed in production builds regrettably. We are currently working a lot on SAT>IP support as we are not completely standard compliant as of yet. Therefore, all I can say for now is "keep trying with future updates" within the next quarter. Additionally, I'll try to get my hands on a testing device matching yours to see for myself.

Thank you so much for the report - in fact you are like the first real-life user of SAT>IP with VLC-iOS we are aware of

Same problem with Triax TSS 400 Sat>IP Converter. I can choose channels. When I select a channel the following error occurs:

"Your input can't be opened. VLC is unable to open the MRL ‘http://xx.x.x.xx/dlna/?type=DVB2&src=2& ... mtype=qpsk'. Check the log for details."

VLC for iOS Version 2.7.4 (274.3)

Schöne Grüße Harald

Update to Version 2.7.5 … no error-message occurs, but the stream doesn't start.

Hi,

The SAT>IP support is broken with both "satip://" and "rtsp://".

I do some sniffing in the network using DVBviewer and VideoLAN to isalte the problem. My server is a hardware SAT>IP DVB-S2 server.
Here some results (simplifying):

- DVBviewer (working):

Code: Select all

> OPTIONS rtsp://192.168.3.40:554/ RTSP/1.0 < ok > SETUP rtsp://192.168.3.40:554/?src=1&freq=12012... < ok > PLAY rtsp://192.168.3.40:554/stream=86?addpids=0,17,16 RTSP/1.0 < ok > TEARDOWN rtsp://192.168.3.40:554/stream=86 RTSP/1.0 < ok

- VideoLAN with "rtsp://" (error):

Code: Select all

> OPTIONS rtsp://192.168.3.40:554/?src=1&freq=12012... < ok > DESCRIBE rtsp://192.168.3.40:554/?src=1&freq=12012... < ok > SETUP stream=11369/stream=11373 RTSP/1.0 < bad request > SETUP stream=11369/stream=11373 RTSP/1.0 < bad request ... (repeated around 20~30 times!) > SETUP rtsp://192.168.3.40:554/?src=1&freq=12012... < bad request > OPTIONS rtsp://192.168.3.40:554 RTSP/1.0 < ok > OPTIONS rtsp://192.168.3.40:554/?src=1&freq=12012... < ok > DESCRIBE rtsp://192.168.3.40:554/?src=1&freq=12012... < ok > SETUP stream=11369/stream=11373 RTSP/1.0 < bad request

- VideoLAN with "satip://" (error):

Code: Select all

> SETUP rtsp://192.168.3.40:554/?src=1&freq=12012... > SETUP rtsp://192.168.3.40:554/?src=1&freq=12012... > SETUP rtsp://192.168.3.40:554/?src=1&freq=12012... ... (no responses and repeate >100times!)

Conclusions:

- The correct order of RTSP commands for use a SAT>IP server is:

1) OPTIONS (without parameters).
2) SETUP (with the full URI of the resource).
3) PLAY (with the stream value done by the server).
4) TEARDOWN (with the corresponding stream).

- The current implementation in VLC for the "satip://" protocol is incomplete and unusable.

- The current implementation in VLC for the "rtsp://" protocol with a SAT>IP server can be fixed if:

1) With the first OPTIONS isn't sended any parameter.
2) Don't send any DESCRIBE command prior to start to play.
3) The SETUP command needs to pass the full URI and not the stream (the stream is a response of active one from the server in response of the previous DESCRIBE command).
4) After complete the SETUP, send the PLAY command with the stream number received.

I feel with this information the developers can fix the support for SAT>IP devices.

Sorry, but the satip://-module is officially certified by the SAT>IP spec inventor SES, so I'm very surprised to not see it working with your device. can you please give details about the device in question?

Hello Felix
I am using the Version 3.0.0 on my iPad and it is working again. Thanks for your work!

Great to hear, thanks for the follow-up!
