c5d62e29ca Reland of Add framerate to VideoSinkWants and ability to signal on overuse (patchset #1 id:1 of https://codereview.webrtc.org/2783183003/ )
Reason for revert:
Seem to be a flaky test rather than an issue with this cl. Creating reland, will add code to reduce flakiness to that test.

f24a06406a Recreate WebrtcVideoSendStream if screen content setting is changed.
This avoids the situation where an encoder, not supporting certain
screen content settings, is created for a config where screencast is
off, and later ReconfigureEncoder() is called updating the configuration
but not the encoder instance, causing an inconsistency in the encoder's
InitEncode() call.

20d4547e5d Make VideoSendStreamTest.DoesNotUtilizeUlpfecForH264WithNackEnabled useful again.
This test was inadvertently made useless in https://codereview.webrtc.org/2558303002/.
Prior to that CL, at least 100 media packets -- but no ULPFEC packets -- had to
be sent before the test claimed that ULPFEC was not utilized. This CL reinstates
that behaviour, but instead of counting packets we expect the test to time out
when ULPFEC should not be utilized.

This solution is simple in code, but increases the test duration from 70 ms
to 10000 ms. Note, however, that the 70 ms duration was for a test that didn't
test anything interesting...

TESTED=Using gtest-parallel locally: 2000 test runs without flakes.

0ad21111fc Revert of Rename RTPVideoHeader.isFirstPacket to .is_first_packet_in_frame. (patchset #1 id:1 of https://codereview.webrtc.org/2574943003/ )
Reason for revert:
breaks downstream project.

Can you make this change in a compatible way using anonymous union:
union {
  bool is_first_packet_in_frame;
  RTC_DEPRECATED bool isFirstPacket;
};
(unfortunetly this this treak breaks braced initialization in rtp_rtcp_impl_unittest.cc,
so that should be rewritting in a more classic way)

Previously ProbeController was starting probing as soon as SetBitrates()

is being established. Now ProbeController receives notifications about
network route changes. This allows to start probing only when transport
is connected. This also makes it possible to restart probing whenever
transport route changes (will be done in a separate change).

This CL stops using hardcoded payload types for different video codecs
and will dynamically assign them payload types incrementally from 96 to

 * Replaces 'std::vector<VideoCodec> DefaultVideoCodecList()' in
   webrtcvideoengine2.cc with an explicit WebRtcVideoEncoderFactory for
   internally supported software codecs instead. The purpose is to
   streamline the payload type assignment in webrtcvideoengine2.cc which

 * Removes webrtc::VideoEncoder::EncoderType and use cricket::VideoCodec
   instead.
 * Removes 'static VideoEncoder* Create(EncoderType codec_type)' and
   moves the create function to the internal encoder factory instead.
 * Removes video_encoder.cc. webrtc::VideoEncoder is now just an
   interface without any static functions.
 * The function GetSupportedCodecs in webrtcvideoengine2.cc unifies
   the internal and external codecs and assigns them payload types
   incrementally from 96 to 127.
 * Updates webrtcvideoengine2_unittest.cc and removes assumptions about
   what payload types will be used.

08127a9449 Reland #2 of Issue 2434073003: Extract bitrate allocation ...
This is yet another reland of https://codereview.webrtc.org/2434073003/
including two fixes:

1. SimulcastRateAllocator did not handle the screenshare settings properly for numSimulcastStreams = 1. Additional test case was added for that.
2. In VideoSender, when rate allocation is updated after setting a new VideoCodec config, only update the state of the EncoderParameters, but don't actually run SetRateAllocation on the encoder itself. This caused some problems upstreams.

Please review only the changes after patch set 1.

Original description:

Extract bitrate allocation of spatial/temporal layers out of codec impl.

This CL makes a number of intervowen changes:

* Add BitrateAllocation struct, that contains a codec independent view
  of how the target bitrate is distributed over spatial and temporal
  layers.

* Adds the BitrateAllocator interface, which takes a bitrate and frame
  rate and produces a BitrateAllocation.

* A default (non layered) implementation is added, and
  SimulcastRateAllocator is extended to fully handle VP8 allocation.
  This includes capturing TemporalLayer instances created by the
  encoder.

* ViEEncoder now owns both the bitrate allocator and the temporal layer
  factories for VP8. This allows allocation to happen fully outside of
  the encoder implementation.

This refactoring will make it possible for ViEEncoder to signal the
full picture of target bitrates to the RTCP module.

e6f98c7a37 Remove RED/RTX workaround from sender/receiver and VideoEngine2.
In older Chrome versions, the associated payload type in the RTX header
of retransmitted packets was always set to be the original media payload type,
regardless of the actual payload type of the packet. This meant that packets
encapsulated with RED headers had incorrect payload type information in the
RTX header. Due to an assumption in the receiver, this incorrect payload type
information would effectively be undone, leading to a working system.

Albeit working, this behaviour was undesired, and thus removed. In the interim,
several workarounds were introduced to not destroy interop between old and
new Chrome versions:
  (1) https://codereview.webrtc.org/1649493004
      - If no payload type mapping existed for RED over RTX, the payload type
        of the underlying media would be used.
      - If RED had been negotiated, received RTX packets would always be
        assumed to contain RED.
  (2) https://codereview.webrtc.org/1964473002
      - If RED was removed from the remote description answer, it would be
        disabled in the local receiver as well.
  (3) https://codereview.webrtc.org/2033763002
      - If RED was negotiated in the SDP, it would always be used, regardless
        if ULPFEC was negotiated and used, or not.

Since the Chrome versions that exhibited the original bug now are very old,
this CL removes the workarounds from (1) and (2). In particular, after this
change, we will have the following behaviour:
  - We assume that a payload type mapping for RED over RTX always is set.
    If this is not the case, the RTX packet is not sent.
  - The associated payload type of received RTX packets will always be obeyed.
  - The (non)-existence of RED in the remote description does not affect the
    local receiver.
The workaround in (3) still needs to exist, in order to interop with receivers
that did not have the workarounds in (1) and (2) removed. The change in (3)
can be removed in a couple of Chrome versions.

TESTED=Using AppRTC between patched Chrome (connected to ethernet) and standard Chrome M54 (connected to lossy internal Google WiFi), with and without FEC turned off using AppRTC flag. Also using "Munge SDP" sample on patched Chrome over loopback interface, with 100ms delay and 5% packet loss simulated using tc.

Extract bitrate allocation of spatial/temporal layers out of codec impl.

This CL makes a number of intervowen changes:

* Add BitrateAllocation struct, that contains a codec independent view
  of how the target bitrate is distributed over spatial and temporal
  layers.

* Adds the BitrateAllocator interface, which takes a bitrate and frame
  rate and produces a BitrateAllocation.

* A default (non layered) implementation is added, and
  SimulcastRateAllocator is extended to fully handle VP8 allocation.
  This includes capturing TemporalLayer instances created by the
  encoder.

* ViEEncoder now owns both the bitrate allocator and the temporal layer
  factories for VP8. This allows allocation to happen fully outside of
  the encoder implementation.

This refactoring will make it possible for ViEEncoder to signal the
full picture of target bitrates to the RTCP module.

2cb155aa8a Remove deprected functions from EncodedImageCallback and RtpRtcp
Removed EncodedImageCallback::Encoded() and RtpRtcp::SendOutgoingData().
These methods should no longer be used anywhere and it's safe to remove
them.
