dce0cdf548 audiostreamalign: Don't report disconts for every buffer if alignment-threshold is too small 
If it is too small, the maximum allowed diff becomes 0 samples which would then
trigger if there is no discontinuity at all.

2766e4816a v4l2object: Fixed framerate negotiation 
We had a problem with negotiation of the framerate.

Gstreamer was querying the FRAMEINTERVALS based on the max frame size
instead of the desired frame size.

This was resulting in non-negotiated errors when trying to run with a
smaller frame size and fps higher than the max for the max image size.

Fx the max framerate for 1024x1024 RGB on CMOSIS4000 is 28.292
While for 1024x100 RGB it is 280.867

But Gstreamer would allow any framerates bigger than 28.292 no matter
the frame size used...

I have fixed it by 1st changing the CAPS query to use the minimum frame
size instead of maximum.
This however has the downside of allowing gstreamer to negotiate
framerates that are too high if the image size is bigger than the
minimum.
This is not a huge problem since our driver just CLAMPS the fps value to
the max then.

However gstreamer was not being properly notified of this change, and
would therefore report a wrong fps in the CAPS structure.
Note that the fps would be correct inside the buffer info.
Since gstreamer was reading the fps back after setting it.
It was just not being "propagated" to the CAPS structure.
I have also added a WARNING to this point so we can see if the fps that
gstreamer tries to apply was accepted or not.

And the next part of the fix was to add a framerate check after the
frame size has been established.
I did this inside the fixate_caps function of the v4l2src, which was
calling the TRY_FMT in order to check if the format was correct.
So I just added a check for the ENUM_FRAMEINTERVALS in there.

And now we get the non-negotiated again if the fps is too high for the
selected frame size.
Also added a couple of warnings so it is easy to see that this was the
cause.

244b00ac08 mpegts: Add custom mapping for vp9 
This is a custom mapping. There isn't much needed apart from that to store vp9
in mpeg-ts since the bitstream is self contained.

Since there are no official specification we don't want people to be mistaken in
believing that. Therefore that mapping is only used in the muxer if the (new)
property `enable-custom-mappings` is set to TRUE.

* The MPEG-TS Stream Type is Private Data (0x6) with the registration descriptor
  set to `VP09`.
* The Access Unit are VP9 frames stored in PES packets
* As there is no emulation prevention byte in VP9 elementary stream, the can be
  misdetection of PES start code. To avoid this, the start of a PES packet must
  be signalled using the Payload Unit Start Indicator in the transport packet
  header

a1c92c0cb1 mpegvideoparse: do not set delta unit flag on unknown frame type 
When encoding an image to mpeg2 video, with something like:
  gst-launch-1.0 encodebin name=e profile=mpegpsmux:video/mpeg,mpegversion=2,systemstream=false ! \
                 filesink location=sample.mpg filesrc num-buffers=1 blocksize=$(stat -c%s sample.png) \
                 location=sample/dts.png ! pngdec ! e.
The only frame's type is set to an invalid value 0
The consequence is that mpegvideoparse sets the delta unit flag on the buffer because
it is not an I frame, then decodebin3 drops this only frame because the delta
unit flag is set and the decoder receives eos before it was able to receive any
encoded data

2080aff70c adapter: Improve documentation for gst_adapter_available() 
When I first read the documentation of gst_adapter_available() and
gst_adapter_available_fast() I got quite confused as it seemed that
both performed the same purpose but one was slower than the other.

I shared it with other people and found they also arrived at the same
wrong conclusion.

Hopefully this patch will make the actual purpose clearer.

4702cae7ff tutorials: gstreamer tools: fix broken webm to ogg transcode pipeline 
The pipeline would error out with not-negotiated. Reason is that
the webm file doesn't have an average frame duration set in the
headers, so matroskademux outputs framerate=0/1, but theora in
Ogg really requires a fixed framerate, so that errors out.

Change example to H.264/AAC in MP4, which is more useful.
