Icecast - Apr 2019 - players who cannot handle switching to a fallback mount point?

Hi, 

We use Icecast version 2.4.4 and use mountpoint /main and include use
fallback-mount.
When the /main is offline 92% of the listeners go to fallback-mount and
8% disconnect. 

The format is 96k AAC and we have 8 mountpoint and 8 fallback-mount
points include extra fallback files AAC. 

Are there any players who cannot handle switching to a fallback mount
point?

Best regards,
Michel

Are the fallback streams exactly the same characteristics as the
streams they're associated with?

Are they live or are they files served by Icecast?  (File serving is
not bitrate constrained in mainstream Icecast, so will completely fill
listeners' players' buffers, possibily requiring a reconnect to get
back to live if the buffer is large.)

Hi Paul,

Thanks for the quick response!
We use the same type of encoder (Sam Cast) both live for both 
mountpoints on 96 Kb Joint Stereo.

it is difficult to see if it is exactly the same. Is there a player that 
show exactly this? I will check this.

We have use the limit-rate in our config. Thats work better for go to 
play the last fallback-mount file (i test this).

See here our part of the config:

<mount>
<mount-name>/aac</mount-name>
<password>xxxxxxx</password>
<public>1</public>
<hidden>0</hidden>
<limit-rate>96k</limit-rate>
<fallback-mount>/fk-aac</fallback-mount>
<fallback-override>1</fallback-override>
<max-listeners>1500</max-listeners>
</mount>

<mount>
<mount-name>/fk-aac</mount-name>
<password>xxxxxxx</password>
<public>1</public>
<hidden>1</hidden>
<limit-rate>96k</limit-rate>
<fallback-mount>/aac.aac</fallback-mount>
<fallback-override>1</fallback-override>
<max-listeners>1500</max-listeners>
</mount>

Best regards,

Michel

We use Icecast & ezestream, 128 and 44100 mp3 with a hybrid player HTML and
flash, as long as we keep to the exact settings defined in the
configuration, we have success. no drop outs etc.....that we are aware of.
We are using win buss vista 64 if you can believe that...
Thank you
