Misc. field - Stream stability information
The periodic messages have a miscellaneous information field. This contains information about the
stream stability. This information is printed in the Misc column on the Streamit Device portal and the
ADP. The stream stability is represented by a number of counters.
When
during playback
the counters have value 0, then no streaming issues have occurred. Other values,
especially high counter values, or consistent non-zero values might require your attention. The meaning
of the values is explained in the following table.
str.to
Number of stream timeouts (no data for 5 seconds) since the last ‘periodic’ connection
A stream timeout counter higher than zero does not necessarily mean that the end user has
heard issues with the audio. The Lisa has a buffer that lasts many seconds. Many consecutive
read timeouts will eventually result in an empty audio buffer and the end user will hear a
silence while the device reconnects (and re-buffers), or resorts fallback.
buf.emp
The number of times the buffer of the Lisa ran out of data since the last ‘periodic’ connection
When the device receives less data than it consumes, the audio buffer will run empty. When
this occurs, the end user will hear a silence while the device re-buffers.
str.dsc
The number of times the stream was disconnected since the last ‘periodic’ connection
Each time the connection with the streaming server is terminated, the disconnect counter will
be increased. When no fallback is possible, or when the device was playing a playlist stream,
the device will try to establish the connection as soon as possible and pick up the stream
where it left off. When the connection is re-established before the buffer has run out of data,
the end user will not notice any problems (no silence in the audio). When the device does not
succeed to connect to the stream before the buffer runs out of data, the audio will stop
playing.
When fallback is possible and the device is playing a direct stream (no playlist), a disconnect
from the streaming server will make the device switch to fallback immediately. When this
occurs, the end user will hear a silence while the device prepares to start playing from card.
vs.eof
The number of times the buffer of the Lisa ran out of data since the last 'periodic' connection
This similar to 'buf.emp', but in this case the empty buffer condition was detected by the audio
decoder instead of the application. The total number of times that the buffer ran empty is the
sum of buf.emp and vs.eof.
