Bug #: 53911
Summary: resampler leftover buffer is not taken into account
when rewinding
Classification: Unclassified
Product: PulseAudio
Version: unspecified
Platform: Other
OS/Version: All
Status: NEW
Severity: normal
Priority: medium
Component: core
AssignedTo: [email protected]
ReportedBy: [email protected]

The resampler leftover buffer can contain data from a sink input, data which
has been popped from the sink input implementor but not yet pushed to the
render_memblockq. That data is not currently taken into account when rewinding.
When doing a rewind that affects the resampler, the leftover data is discarded,
and that is not compensated in any way, which means that the data is completely
lost and there's a skip in the audio.
In practice the leftover buffer is rarely used and even if it is used, it will
contain a minimal amount of data, so the user-visible effect of this bug is
minor.
