As requested by a CEF hosted application (https://crbug.com/1406331)
who want to be able to limit the number of threads in a controlled
environment, this CL adds a flag to control the max limit per encoder.
For plumbing-reasons, this is placed in VideoEncoder::Settings but
with a note that this is considered an experimental API with limited
support. For now only LibvpxVp8Encoder uses it and there are no plans
to roll this out.
I have manually confirmed this is working with printf debugging,
--force-fieldtrials=WebRTC-VideoEncoderSettings/encoder_thread_limit:2
and https://jsfiddle.net/henbos/2bd6m7Lt/

Adds a field to EncoderInfo called preferred_pixel_formats which a
software encoder populates with the pixel formats it supports. When a
kNative frame is received for encoding, the VideoStreamEncoder will
first try to get a frame that is accessible by the software encoder in
that pixel format from the kNative frame. If this fails it will fallback
to converting the frame using ToI420.
This minimizes the number of conversions made in the case that the
encoder supports the pixel format of the native buffer or where
conversion can be accelerated. For example, in Chromium, the capturer can
emit an NV12 frame, which can be consumed by libvpx which supports NV12.
Testing: Tested in Chrome with media::VideoFrame adapters.

I have checked all VideoEncoder implementations in Chromium and confirmed they either convert the frame to their preferred pixel format, or just
forward the frame to a delegate encoder.

- video_loopback with NV12 generated frames for VP9, the only
codec supporting NV12, as well as VP8 which only accepts I420 frames.

This includes pieces related to calculating how to adapt, including:
- DegradationPreference
- BalancedDegradationPreference
- AdaptationRequest and last_adaptation_request_
- CanAdaptUpResolution()
The VideoStreamAdapter's interface has changed: VideoSourceRestrictor
methods are now hidden in favor of methods exposing AdaptationTarget.
This CL also does some misc moves:
- GetEncoderBitrateLimits is moved and renamed to
VideoEncoder::EncoderInfo::GetEncoderBitrateLimitsForResolution.
- EncoderSettings moved to a separate file.

This squashes together several input signals that were spread out
through several calls into a single method and calling place:
SetEncoderSettings(), invoked from ReconfigureEncoder(). This is added
to the abstract interface.
This makes the following methods obsolete which are removed:
- SetEncoder(): The VideoEncoder was only used for GetEncoderInfo();
the VideoEncoder::EncoderInfo is now part of the EncoderSettings.
- SetEncoderConfig(): The VideoEncoderConfig is part of
EncoderSettings. The config is used for its codec_type and
content_type enums.
- SetCodecMaxFrameRate(): The max frame rate was the same as
VideoCodec::maxFramerate. VideoCodec is now part of EncoderSettings.
There may be some overlap in information between EncoderConfig and
VideoCodec, but that is outside the scope of this CL, which only makes
sure to bundle encoder settings-like information into one input signal.

There are edge cases where the caching of encoder info will cause
issues. For instance if a sub-encoder fails en Encode call and falls
back to some other implementation, or if the fps targets shift due to
SetRates() triggering new layers to be enabled.
This CL forces a complete rebuild on every call to GetEncoderInfo().
It also adds new logging of when the info changes, as debugging issues
can be very time consuming if we can't tell that happened.

that can be used to create software fallback adapter per simulcast layer.
It also adds logic to check if the encoder supports simulcast natively, if so
it only allocates a single instance and delegates the simulcast logic to that
encoder instead. This means we will be able to remove EncoderSimulcastProxy.

FrameBufferController, where it might be put to good use.
2. Modify RtpVideoSender to respond to the message sent to it

This CL removes two deprecated methods from the VideoEncoder interface:
* int32_t SetRates(uint32_t, uint32_t);
* int32_t SetRateAllocation(const VideoBitrateAllocation&, uint32_t);
These are no longer used, instead the new version must be implemented:
void SetRates(const RateControlParameters&) = 0;
Migrating is straight forward. For the old SetRates, simple replace:
int32_t MyEncoder::SetRates(uint32_t bitrate, uint32_t framerate) {
with
void MyEncoder::SetRates(const RateControlParameters& parameters) {
uint32_t bitrate = parameters.bitrate.get_sum_kbps();
uint32_t framerate =
static_cast<uint32_t>(parameters.framerate_fps + 0.5);
For SetRateAllocation, replace:
int32_t MyEncoder::SetRateAllocation(
const VideoBitrateAllocation& allocation,
uint32_t framerate) {
with
void MyEncoder::SetRates(const RateControlParameters& parameters) {
const VideoBitrateAllocation& allocation = parameters.bitrate;
uint32_t framerate =
static_cast<uint32_t>(parameters.framerate_fps + 0.5);
Two more things to note:
1. The new method is void. Previously the only use of the return value
in production code was to log a more or less generic error message.
Instead, log the actual error from the encoder when it happens,
then just return.
2. The new method is pure virtual; it must be overriden even in test.
This CL is intended to be landed two weeks after creation, on Thursday
May 9th 2019.

This rather large CL replaces all relevant usage of the old
VideoEncoder::SetRates()/SetRateAllocation() methods in WebRTC.
API is unchanged to allow downstream projects to update without
breakage.

This CL wires up the new SetRates() method of the video encoders, and
refactors a few things in the process:
Most notably, the VideoStreamEncoderInterface is update so that the
|target_headroom| parameter is replaced with |link_allocation|, meaning
that instead of indicating bitrate capacity in excess of the target
bitrate, it indicates to total network capacity allocated for the
stream including the target bitrate. This matches the VideoEncoder API.
The VideoEncoder::RateControlParameters struct gets a few new helper
methods.
In VideoStreamEncoder, instead of adding more fields to the
|last_observed_bitrate*| family, uses an optional struct that
inherits from VideoEncoder::RateControlParameters.

This CL changes the API for webrtc::VideoEncoder.
There is a legacy method called SetRates(). This is indicated as being
deprecated, but there seem to be a number of usages still left.
Then there is the new SetRateAllocation() method which takes a
VideoBitrateAllocation instance instead of a single target bitrate.
This CL adds a new version of SetRates() which moves all the existing
parameters in a RateControlParameters struct, and adds a bandwidth
allocation signal. The intent of this signal is to allow the encoder
to know how close to the target it needs to stay. If the encoder rate
is network restricted, it will need to be more aggressive in keep the
rate down and possibly drop frames. If there is some margin for
overshoot, it might do different trade-offs.
Furthermore, the frame rate signal is changes from an integer to a
floating point type in order to get more precise rates at low frame
rates and the return type has been changed to void since the only use
of the previous values to log it and that is better done inside encoder
where the error condition originates.
The intent is to properly deprecate the "old" SetRates() /
SetRateAllocation() methods, send out a PSA and then remove them in two
weeks. Changes required by users should be trivial, as using the new
headroom signal is optional.

This CL paves the way to making FrameBufferController injectable.
LibvpxVp8Encoder can manage multiple streams. Prior to this CL,
each stream had its own frame buffer controller, all of them held
in a vector by LibvpxVp8Encoder. This complicated the code and
produced some code duplication (cf. SetupTemporalLayers).
This CL:
1. Replaces CreateVp8TemporalLayers() by a factory. (Later CLs
will make this factory injectable.)
2. Makes LibvpxVp8Encoder use a single controller. This single
controller will, in the case of multiple streams, delegate
its work to multiple controllers, but that fact is not visible
to LibvpxVp8Encoder.
This CL also squashes CL #126046 (Send notifications of RTT and
PLR changes to Vp8FrameBufferController) into it.

This cl deprecates the FrameType enum, and adds aliases AudioFrameType
and VideoFrameType.
After downstream usage is updated, the enums will be separated
and be moved out of common_types.h.
