Like pngenc, automatically send an EOS message.
Example of bin:
appsrc ! jpegenc snapshot=true ! filesink location=out.jpg
This is especially useful for limited/slow hardware.
Otherwise calling gst_video_convert_sample() is a better option
(internally uses videoconvert and videoscale).

If a lot of seek method is called very quickly, sometimes data reading
and do_request occurs while seek flush event is occurring and error
occurs because retry_count
reaches to the max. Thus, reset retry_count if flush occurs after
do_request and read_buffer.

Some cameras fail to send an end-of-image marker (EOI)
and can't be properly decoded by either JPEG or libjpeg.
This commit parses the frame, making sure it has an EOI.
If there isn't one, the EOI gets added to the buffer.
A similar fixup is done in the rtpjpegdepay element,
and it makes sense to do it in jpegdec as well.

This reverts commit 47fd4d391e.
This patch is incorrect. It doesn't actually compile, and causes a crash
because the viv-fb window implementation needs a native EGL handle
to pass to fbCreateWindow, but the GstGLDisplayEGL handleis actually
an EGLDisplay now (and gets cast to the wrong type)
This is a regression introduced by "03db374 - souphttpsrc: retry
request on early termination from the server"
The problem was that when seeking back to 0, we would not end up calling
add_range_header() which in addition to adding range headers *ALSO* sets
the read_position to the requested one.
This would result in a wide variety of later failures, like reading
again and again instead of stopping properly.
This simplifies the code a lot without any functional changes apart from
not closing the display connection. Closing the display connection is
not safe to do as it is shared between all other code in the same
process and no reference counting or anything happens at the platform
layer.
Move the package defines for GST_PLUGIN_DEFINE from the
command line into the source file to avoid quoting issues
(-DPACKAGE_NAME="foo" means the quotes won't actually make
it to the compiler and then it no longer gets a string constant).
1. Propagate the GstGLDisplay we create
2. Add the created GstGLContext to the propagated GstGLDisplay
Otherwise with multi-branch GL pipelines involving gtkglsink, things
will fall apart and errors will be genarated somewhere.
Except for gst/gl/gstglfuncs.h
It is up to the client app to include these headers.
It is coherent with the fact that gstreamer-gl.pc does not
require any egl.pc/gles.pc. I.e. it is the responsability
of the app to search these headers within its build setup.
For example gstreamer-vaapi includes explicitly EGL/egl.h
and search for it in its configure.ac.
For example with this patch, if an app includes the headers
gst/gl/egl/gstglcontext_egl.h
gst/gl/egl/gstgldisplay_egl.h
gst/gl/egl/gstglmemoryegl.h
it will *no longer* automatically include EGL/egl.h and GLES2/gl2.h.
Which is good because the app might want to use the gstgl api only
without the need to bother about gl headers.
Also added a test: cd tests/check && make libs/gstglheaders.check

This is useful for autoplay for example. With autoplay, it is necessary to
wait until the scene graph is fully set up. This signal is emitted once the
QML item node is ready. So, inside a connected slot, the pipeline's state
can be set to PLAYING to automatically start playback as soon as the QML
script is loaded.
https://bugzilla.gnome.org/show_bug.cgi?id=786246
This fixes a memory leak. When dropframe-threshold has been set,
libvpx may output less frames than the input ones, which causes
some GstVideoCodecFrames to queue up in GstVideoEncoder's internal
frame queue with no chance of ever being all released. And because
the frames keep references to the input buffers, the input buffer
pool keeps allocating new buffers and memory usage grows very fast.
For example the following pipeline's memory usage grows at a rate
of about 1GB per minute!
videotestsrc ! capsfilter caps=video/x-raw,width=1920,height=1080,framerate=30/1,format=I420 ! \
vp8enc target-bitrate=1000000 end-usage=cbr dropframe-threshold=95 ! fakesink

Instead of just sending a sticky event with them downstream. This allows
getting the HTTP headers easily in the application, and especially also
on errors.
QML can destroy the video widget at any time, leaving
us with a dangling pointer. Use a lock and a proxy
object to cope with that, and block in the widget
destructor if there are ongoing calls into the widget.
Soup allows only up to two connections per host in a session,
if we use default value. When session sharing is used, however,
more connections might be required in a session.
(e.g., multi-audio adaptive streaming case)
https://bugzilla.gnome.org/show_bug.cgi?id=784495
Currently we only allowed HTTP proxy. Don't filter for the scheme, just check
if it looks like an URI. Soup will warn if the URI is invalid or if
proxy protocol is not supported. This enables using SOCKS 4/5 which is
directly implemented into GIO.
https://bugzilla.gnome.org/show_bug.cgi?id=783012
This allows timing out on network errors much earlier
(currently it takes ~15min to timeout) and we can still
unlock and change state in the meantime.

Tags are pushed to "videosrcpad"/"audiosrcpad" in
gst_dvdemux_add_pad() method, however they will be NULL
in this method, hence tags are not pushed.
Instead, send tag event to "pad" created gst_dvdemux_add_pad().

souphttpsrc now shares its SoupSession with other elements in the
pipeline via GstContext if possible (session-wide settings are all the
defaults), or if the context was forced by the application.
This allows multiple souphttpsrcs to reuse connections, cookies, etc.

Let libsoup handle redirection automatically.
And then, to figure out redirection uri, extract it on "restarted"
callback which will be fired before soup_session_send() is returned.
https://bugzilla.gnome.org/show_bug.cgi?id=778428
Fix a regression introduced by commit 183695c61a (refactor to use
Soup's sync API). The code previously attempted to reconnect when the
server closed the connection early, for example when the stream was put
in pause for some time.
Reintroduce this feature by checking if EOS is received before the
expected content size is downloaded. In this case, do the request
starting at the previous read position.
https://bugzilla.gnome.org/show_bug.cgi?id=776720
This check must be done only when we are sure the request was
successfully sent. soup_session_send() might fail without setting the
status code. In this case status code is 0 so we would only catch the
error after the seek range check. In this case we would report an error
saying that the seek range was not respected, instead of reporting the
underlying error that triggered the soup_session_send() failure.
https://bugzilla.gnome.org/attachment.cgi?bugid=777222
... so as to allow one clearly defined (absolute) positioning mode
that can cater for a variety of absolute but also relative positioning
with respect to edge or center.
The flow return values was stored in the element before because the
result had to be set from callbacks. This is not the case anymore, we
can return the flow result directly from functions, making the code
easier to understand.
https://bugzilla.gnome.org/show_bug.cgi?id=777222
The current code configures libsoup to handle redirections
transparently, without informing the caller, thus preventing the element
to record the redirect code and location uri.
Fix this by always setting the SOUP_MESSAGE_NO_REDIRECT, preventing
libsoup from handling the redirection. When we receive a redirection
request and libsoup can safely handle it, return a custom error which
triggers a retry with the new URI.

The encoder fails to initialise when we try to set GST_TAG_PREVIEW_IMAGEs
sent to use by qtdemux from iTunes-generated m4a files. We should
not just blindly translate the PREVIEW tag to file icon image types,
but check if the specific conditions required are met (i.e. image
type 1 must be a 32x32 PNG icon, and what we're getting is 500x500).

souphttpsrc maintains two variables for the position:
* 'request_position' is where we want to be
* 'read_position' is where we are
During Normal operations both are updated in sync when data arrives. A seek
changes 'request_position' but not 'read_position'.
When the two positions get out of sync, then a new request is send and the
'Range' header is adjusted to the current 'request_position'.
Without this patch, if reading fails, then the source is destroyed. This
triggers a new request, but the range remains unchanged. As a result, the
old range is used and old data will be read.
Changing the 'read_position' to -1 makes it explicitly different from
'request_position' and as a result the 'Range' header is updated correctly.

GstAudioRingBuffer doesn't needs us to have at least 2 segments. We make
sure that if our buffer parameters are such that the maxlength is not at
least 2x fragsize, we still request the ringbuffer to keep that much
space so it continues to work.

If jackd changes the buffer size or sample rate, jackaudiosink hangs
and can't be stopped. This also happens if jack is configured as slave
and a gstreamer pipeline is started on the slave machine while the jack
master isn't running yet. If the the jack master is started it changes
the buffer size / sample rate and jackaudiosink can't be stopped.
This fix calls jack_shutdown_cb when jack_sample_rate_cb or
jack_buffer_size_cb is called.

At the end of a range request, we don't want to return GST_FLOW_EOS otherwise
the last bytes we just read will be dropped by basesrc.
Instead just return GST_FLOW_OK (which was set just before) and let basesrc
handle the fact we are at the end of the segment.
If we're at the end of a range request, read again to let libsoup
finalize the request. This allows to reuse the connection again later,
otherwise we would have to cancel the message and close the connection.
We have to get rid of the message on EOS when the complete stream is read to
remember that we successfully finished handling this specific message.
Otherwise we will cancel it later and close the connection instead of reusing
it at a later time.
It might also make sense to reuse connections if a non-200 response is
received. As long as there was no connection error, the HTTP connection should
be re-usable.
