Description Enrique Ocaña 2023-07-21 09:56:54 PDT

During replacement of buffered range, SourceBuffer may fail to remove some samples if its PTS falls in "contiguousFrameTolerance" gap introduced in https://bugs.webkit.org/show_bug.cgi?id=190085.

The problem can be seen with this test https://emutavchi.github.io/tests/mse/mse_sample_replacement_test.html and instrumentation on WebKit side that logs the append number for each sample: https://github.com/emutavchi/WebKitForWayland/commit/8d272af173a4ba23a0922949a02d0c7f79339158
