Rest API play/pause and Web Radio stuck in playing

[Slawo60]

Hi,

I have an issue with a REST API. I have a script that pauses volumio for a call and resume last state when done. It works well when playing a music file, but it stuck volumio when playing web radio I do curl volumio.local/api/v1/commands/?cmd=pause then curl volumio.local/api/v1/commands/?cmd=play

It works one time, then it's stuck in pause state, but the player is actually playing. The REST API and the web GUI cannot pause the web radio.To get unstuck, I must change radio.

558 seems to be the same issue.

I tried to reproduce this and found something strange. This is on v2.714.

• play a track from my NAS source
• curl volumio.local/api/v1/commands/?cmd=pause - pauses
• curl volumio.local/api/v1/commands/?cmd=play - play

So far so good. Now try a web radio.

• play a web radio (Audiophile Baroque, http://94.23.201.38:8000/stream)
• curl volumio.local/api/v1/commands/?cmd=pause - pauses
• curl volumio.local/api/v1/commands/?cmd=play - play
• press play/pause on the web ui. Nothing happens, it keeps playing.
• curl volumio.local/api/v1/commands/?cmd=pause - keeps playing

So it seems like it works exactly once, then gets into a state where pause is ignored. The log below was produced by:

• reboot
• clear queue
• play a web radio (Audiophile Baroque)
• curl volumio.local/api/v1/commands/?cmd=pause - pauses
• curl volumio.local/api/v1/commands/?cmd=play - plays edit
• curl volumio.local/api/v1/commands/?cmd=pause - keeps playing, but returns {"time":1583544110568,"response":"pause Success"} /edit
• press play/pause on the web ui. Nothing happens, it keeps playing The UI icon showing was the 'play' icon, it should have been the 'pause' icon.
• send log.

Looking at the log I think the issue might be related to this, but that's just a guess.

I found the solution. Because the web radio is a audio stream, "pause" doesn't really work. I've used volumio.local/api/v1/commands/?cmd=stop and it's working just fine.

Thank you very much for you help.

Nonetheless it would be good if the web UI play/pause worked as expected...

[camelcamro]

yes, so, that is a bug. because i can not use as a solution the "STOP", eg: a stop would change the position (eg: playing a mp3 file), and i would loose the position.

so, this bug is still open since 3 YEARS. is developing ongoing on new features which can be sold only ? or also trying to fix first the basics ?

[Slawo60]

The workaround i used for my script is to check if the type media is a webradio then stop instead of pause
