Sebastian Dröge a0b69c8dac vp[89]enc: Properly convert between GStreamer and encoder timebase 
... by switching numerator and denominator when scaling.

Sebastian Dröge eb365cc3bb vp[89]enc: Don't set timebase from the framerate 
The framerate very often is just an indication of the ideal framerate, not the
actual framerate of the stream. By just using the framerate, we confuse the
rate control algorithm algorithm as multiple frames will map to the same PTS
or have durations of 0.

Tim-Philipp Müller 2e412a447a docs: update example pipelines in element docs 
Mostly gst-launch -> gst-launch-1.0
Use autovideosink/autoaudiosink more often.
Sprinkle some converters here and there.

Olivier Crête 12867fcb3d vp8enc: Expose VP8 width/height limitations in the caps template 
The VP8 format specification (RFC 6386 section 18.1) specifies
that the maximum size is 16383x16383.

Sebastian Dröge 627e492b7e vp[89]dec: Drop frames that have no output buffer because of errors 
finish_frame() assumes that there is an output buffer.

Sebastian Dröge 379621fd0b vp8enc: Use 0 as duration for the EOS "frame" 2015-03-02 15:06:09 +01:00
Sebastian Dröge 51ebca3c03 vp{8,9}enc: Tell the encoder about actual timestamps and durations of frames 
... instead of just counting frames. The values are supposed to be in timebase
units, not frame units. This fixes various quality problems with VP8/VP9
encoding and in general makes the encoder behave better.

Thanks to Nirbheek Chauhan for noticing this bug.

Nicolas Dufresne 501a53b26d vpxdec: Fix calculation of width in bytes 
Right now we only support I420, but vpx seems to support more formats.
This will prevent hard to find bug in the future.

Nicolas Dufresne 1521f65e8d vpxdec: Don't memcpy in frame map failed 
This avoid a crash if mapping the frame failed.

Aurélien Zanelli d0e8a385e0 vpx: mark arnr-type properties as deprecated and set them to no-op 
ARNR type control in libvpx has been deprecated so this commit mark the
vp8enc and vp9enc associated properties as deprecated and change their
behavior to just display a warning message.

Aurélien Zanelli 130873c8fd vpx: remove compatibility defines 
We are guaranteed to have VPX_IMG_FMT_I420, VPX_PLANE_Y,
VPX_PLANE_U and VPX_PLANE_V as we require libvpx > 1.1.0.

Sebastian Dröge 9eb22a533b vp9dec: Get input width/height from the codec instead of the input caps 
They are reported properly by libvpx if the correct struct members are used.
This also fixes handling of resolution changes without input caps changes.

Tom Greenwood 5430b6c351 vp8dec: Fix for handling resolution changes when decoding VP8 
If the resolution changes in the bitstream without the input caps changing we
would previously output corrupted video or crash.

Sebastian Dröge 943520382f vp8dec: Error out gracefully if we get an unsupported color format 
In theory we can only get I420 though, just to be on the safe side.
