When tags are populated elsewhere, do not run discovery on them again.
It is possible they were discovered in more efficient maner
(e.g. from playlist data itself).
This avoid us downloading each media item separately after all
playlist items are queued.
Move as harvest URI demuxer since it is supposed to work only with
harvest data from extractable src. Also change caps media type
to "text/x-uri" which is non-standard, but we have to differentiate
single URI from harvest and URI list (one or more URIs).
Handle "ClapperPlaylistParsed" messages on playbin bus by updating current media
item (playlist) to redirect to the first item in that playlist (with changed tags)
and appending remaining items to the queue after that playlist position.
This basically means that playlist gets resolved into simply adding more
items to the queue. This should also work with nested playlists within playlist.
This reverts commit f63e13ed39.
This workaround does not work, since GStreamer build manifest we use
as shared module from Flathub has explicitly enabled libmpeg2 support.
With some workarounds, we can make enhancers that were ported from
features still be loaded and used within single process without
requirement for building Clapper with their old implementations disabled.
Since MPRIS enhancer already has workarounds in place, lets just remove
all code that was skipping its loading.
Detect and auto switch thread to main if done from a different one.
With this, apps can still continue to implement thread switch and doing
multiple insertions/deletions within single main thread invoke or simply
call this function from a different thread for convenience.
Allow apps to enable or disable given enhancer instances from being created.
Also as a safely measure, by default only enable enhancers that work
on-demand (extractables) and disable others (reactables).
An object for managing instances of reactable type of enhancers.
Based on/similar to features manager which along with Clapper
features objects gets deprecated in favour of reactables.
We keep and use old functions in code for the compatibility reasons with
older API versions. Do not print warnings about them being deprecated when
compiling Clapper library that has and uses such function internally.
Allow apps to read and/or populate initial taglist within media item.
Apps might care about other tags that Clapper application does not,
so this single property allows them to read whatever tag they might need.
Newly created enhancer proxies hold param specs with a reference
on each and unref them when finalized. For this reason, copied
proxy objects needs to ref pspecs from source, otherwise it would
do an unref without holding a reference on object during destruction.
This thread invoke is done mainly to support testing with gst-launch-1.0,
otherwise no need when used with "ClapperGtkVideo". We can avoid doing this,
by checking whether this type was already registered in which case it means
that "ClapperGtkVideo" widget is used within GTK application and registered
before sink starts processing data.
In case of "ClapperGtkVideo" we might run into situation where these two threads
are stuck waiting for each other to be idle. This change works around this issue.
Fixes#555
