Description Przemyslaw Gorszkowski 2023-07-05 01:35:06 PDT

Currently when TrackBuffer::removeSamples is called and erasedRanged is created from the samples, removing small gaps between samples are not done. It causes that in some cases many separated ranges are created which has impact on performance of removing samples.

It can be fixed in similar way as it is done in SourceBufferPrivate::processMediaSample when range is extended with new sample and "fudge factor" is used to eliminate the small gaps between samples.
