Description Alicia Boya García 2019-08-11 08:01:58 PDT
This patch has been splitted from the original WebKitMediaSrc rework
patch (https://bugs.webkit.org/show_bug.cgi?id=199719).

Unlike other parsers, vorbisparse has latency (in the sense that when
it gets a chain call with a series of complete frames, it may not emit
the parsed frames until another chain in the future), which makes it
inappropriate for AppendPipeline, as there is no good way I know to
flush it.

But actually vorbisparse is not known to be necessary and it was only
introduced for consistency with other formats. Parsers are used in
AppendPipeline to reconstruct information that is lost due to poor
muxes. There have been no reported cases of this being a problem with
Vorbis in WebM, so I'm just removing the parser.
