Nirbheek Chauhan 6351c0becc glvideomixer: Point to compositor for the pad properties documentation 2014-12-27 11:05:17 +00:00
Nirbheek Chauhan a27431c680 compositor: Document the pad properties 2014-12-27 11:04:52 +00:00
Sebastian Dröge b9312fe9a2 videoaggregator: Use the src query implementation of aggregator as the default case 2014-12-22 22:12:02 +01:00
Sebastian Dröge 5c9472f78c videoaggregator: Don't try to map NULL buffers 2014-12-18 22:04:38 +01:00
Sebastian Dröge ccd24a3577 videoaggregator: Make sure to always update the pad's videoinfo together with buffers 
Otherwise the videoinfo and the buffer content can go out of sync.

Sebastian Dröge a64445e543 compositor: Fix memory leak when no buffer is available for a pad currently 
CID 1258718
 2014-12-18 11:49:09 +01:00
Sebastian Dröge 6f0eb92d72 aggregator: Add function to allow subclasses to set their own latency 
For audiomixer this is one blocksize, for videoaggregator this should
be the duration of one output frame.
 2014-12-17 19:51:32 +01:00
Sebastian Dröge 26d1a22e90 aggregator: Add a timeout parameter to ::aggregate() 
When this is TRUE, we really have to produce output. This happens
in live mixing mode when we have to output something for the current
time, no matter if we have enough input or not.

Matthew Waters e354149436 aggregator: make the src pad task drive the pipeline for live pipelines 
This removes the uses of GAsyncQueue and replaces it with explicit
GMutex, GCond and wakeup count which is used for the non-live case.

For live pipelines, the aggregator waits on the clock until either
data arrives on all sink pads or the expected output buffer time
arrives plus the timeout/latency at which time, the subclass
produces a buffer.

Matthew Waters 8fe8510d80 videoaggregator: always try to use newer buffers 
instead of dropping them for being too old.  This ensures that
the newest buffer is always used for rendering
 2014-12-16 16:49:49 +01:00
Thibault Saunier e8fda3a28a videoaggregator: Hide some more fields from the API 
+ Add some documentation

Matthew Waters 85febbbafb gl: fixup vao and vbo usage for legacy GL 2014-12-11 19:41:23 +11:00
Sebastian Dröge b212aca601 compositor: Failure to map a video frame is not just a warning 
Also add some warning debug output if mapping a output buffer fails
 2014-11-28 10:23:55 +01:00
Sebastian Dröge 6354e0235a videoaggregator: Failure to map a video frame is not just a warning 2014-11-28 10:22:44 +01:00
Matthew Waters c90f7001b1 gldisplay: implement runtime GL api filtering 
Needed so that the pipeline/application can limit the choice of GL api
to what it supports
 2014-11-28 09:14:26 +11:00
Matthew Waters 8f86923b00 gl: add a sync meta for synchronizing across GL contexts 
A context can create a GLsync object that can be waited on in order
to ensure that GL resources created in one context are able to be
used in another shared context without any chance of reading invalid
data.

This meta would be placed on buffers that are known to cross from
one context to another.  The receiving element would then wait
on the sync object to ensure that the data to be used is complete.

Matthew Waters ad77f0392f glvideomixer: add support for gl3 2014-11-28 09:14:25 +11:00
Sebastian Dröge 0b73de023c videoaggregator: Minor cleanup 2014-11-27 21:23:36 +01:00
Sebastian Dröge 3e9b001013 compositor: Implement rescaling of the input via pad properties 
compositor has now the same interface as glvideomixer.
 2014-11-27 21:23:04 +01:00
Sebastian Dröge fdc87a52f2 videoaggregator: Copy over more fields from the relevant video-info 
gst_video_info_set_format() will reset the complete video-info, but
we want to keep values like the PAR, colorimetry and chroma site.
Otherwise we risk setting different values on the srcpad caps than
what is actually inside the buffers.
 2014-11-27 20:34:25 +01:00
Sebastian Dröge 4233ba4ca4 videoaggregator: Directly use the converters video-info instead of recalculating it 2014-11-27 20:25:29 +01:00
Sebastian Dröge 00880b5830 videoaggregator: Do source pad negotiation only from the aggregated function 
Otherwise we might negotiate from the sinkpad streaming threads at
the same time as on the srcpad streaming thread, and then all kinds
of crazy bugs happen that don't make any sense at all.

Thibault Saunier ec45cbda22 videoconvert: Hide all conversion related fields 
And do not delay the setting of the conversion_info

Thibault Saunier 8cc214fdb8 videoaggregator: Expose vmethods to set converters and prepare/clean frames 
This gives more flexibility to the subclasses and permits to remove the
GstVideoAggregatorClass->disable_frame_conversion ugly API.

WARNING: This breaks the API as it removes the disable_frame_conversion
field

API:
  + GstVideoAggregatorClass->find_best_format
  + GstVideoAggregatorPadClass->set_format
  + GstVideoAggregatorPadClass->prepare_frame
  + GstVideoAggregatorPadClass->clean_frame

  - GstVideoAggregatorClass->disable_frame_conversion

Thibault Saunier a806b40135 videoaggregator: Let a full renegotiation happen after removing the last pad 
With the current code, we will end up setting the preferred downstream
format as the srcpad format, and it might not be accepted by the next
sinkpad to be added. We should instead let the next sinkpad reconfigure
everything.
 2014-11-27 19:10:58 +01:00
Sebastian Dröge fc593bd2ca videoaggregator: Also sync pad properties to the controller if conversion is disabled 2014-11-26 13:06:21 +01:00
Sebastian Dröge dbadc6c8a5 compositor: Remove unused zorder pad property 
It's handled in videoaggregator already.
 2014-11-26 12:42:24 +01:00
Sebastian Dröge 170def9d43 compositor: GstVideoMeta is supported just fine, tell upstream about that 
Also provide a GstVideoBufferPool to upstream just in case.

Matthew Waters c337aab991 glupload: rearchitecture for non GLMemory inputs/outputs

Luis de Bethencourt 2bf4a94179 videoaggregator: remove storage of never used values 
These two values are stored just before the function returns and they go out of
scope.
 2014-10-30 14:52:13 +00:00
Matthew Waters eb11906f01 glmixer: don't get the current caps from GstVideoInfo for the srcpad 
It's missing the caps features needed.
 2014-10-30 23:08:00 +11:00
Wang Xin-yu (王昕宇) b151f564c2 glmixer:fix incorrect parameter passed to handle_set_context 2014-10-29 20:43:31 +11:00
Matthew Waters 33584480b5 glmixer: override the caps query in order to 'convert' capsfeatures 
Otherwise, it is only possible for the sink pads and the src pads to
have the exact same caps features.  We can convert from any feature
to another feature so support that.
 2014-10-24 00:35:22 +11:00
Matthew Waters 6687d39734 glmixer: override the accept caps query in order to 'convert' capsfeatures 
Otherwise, it is only possible for the sink pads and the src pads to
have the exact same caps features.  We can convert from any feature
to another feature so support that.

Matthew Waters 165cdd20a7 videoaggregator: fixate the parts of the caps we don't know how to deal with 
fixes glvideomixer with video/x-raw,width=foo i.e. no format field.
 2014-10-21 02:53:02 +11:00
Matthew Waters 7b4db67f6c glbufferpool: add the GstVideoGLTextureUploadMeta buffer pool option 2014-10-21 02:00:09 +11:00
Matthew Waters 8bf2acba1d videoaggregator: operate on caps rather than video info 
Otherwise the CapsFeatures will be lost along with the possibility
of multiple output types and formats.

Sebastian Dröge 318b55e3ae glmixer: Call the pad's parent class finalize method 2014-10-13 13:27:55 +02:00
Sebastian Dröge 21275caae5 glmixer: Only finalize the other context in finalize() 
Otherwise we change a value of a property when going to READY state,
which is unexpected behaviour.
