Summary [MSE][GStreamer] Support markEndOfStream() before appendBuffer()
Enrique Ocaña
Reported 2024-08-27 07:10:03 PDT
WebKit MSE can't complete playback when JavaScript performs MediaSource.markEndOfStream() before appending any samples with SourceBuffer.appendBuffer(). That's on the current GStreamer version used in the test bots (gst 1.24). On older GStreamer versions (eg: 1.18.6), parsebin (from the playback pipeline) emits an unrecoverable error as well.

This issue has reappeared downstream (wpe-2.46, GStreamer 1.18) and also has been reproduced upstream when the test case is exercised in a loop and the race condition of an error occurs while errors are ignored, but the GstMessage with the error takes a moment to propagate to the main thread (when the errors are no longer ignored).
