This is possible now that we no longer support go1.12 and brings
rclone into line with standard practices in the Go world.
This also removes errors.New and errors.Errorf from lib/errors and
prefers the stdlib errors package over lib/errors.
Basically, solving #3541 with a different approach - bringing in
the upstream upnpav module, and changing ChildCount from int to a
*int to avoid childCount="0" in the XML output when that value is
simply unknown.
Current approach is leading to some recursion issues and according
to the DLNA spec it shouldn't be necessary, anyway.
Seems to be some corner cases that are not being handled, so taking a different
approach that should be a little more robust.
Also, changing resources to be served under a subpath: We've been serving
media at /res?path=%2Fdir%2Ffilename.mp4; change that to be just /r/dir/filename.mp4.
It's cleaner, easier to reason about, and a necessary first step towards just
serving the resources via httplib anyway.
Allows for filename.srt, filename.en.srt, etc., to be automatically associated with video.mp4 (or whatever) when playing over dlna.
This is the "modern" method, which I've verified to work on VLC and in LG webOS 2. There is a vendor specific mechanism for Samsung that I havn't been able to get working on my F series.
Also made some minor corrections to logging and container IDs.
Add a minimal number of mime types to augment go's built in types
for environments which don't have access to a mime.types file (eg
Termux on android)
Fixes#3475
Before this fix serve dlna was only using the built in database of
mime types to look up the mime types of files. On Android (and
possibly other systems) this is very small.
The symptoms of this problem was serve dlna only listing images and
not videos.
After this fix we use the backend's idea of the mime type if possible
which will be more accurate.
Fixes#3475
Mostly trying to get logging to happen through rclone's log methods.
Added request logging, and a trace parameter that will dump the
entire request/response for debugging when dealing with poorly
written clients.
Also added a flag to specify the device's "Friendly Name" explicitly,
and made an attempt at allowing mime types in addition to video.
Again, mostly just copying what I see in other implementations. This
does seem to have done the trick so that I can now pause, fast forward,
rewind, etc., on my Samsung F series.
