This class is thread hostile: none of its methods can be called concurrently.
Public Methods
void SetPtsUnits (uint32_t ticks_per_second_numerator, uint32_t ticks_per_second_denominator)Sets the units used by the presentation (media) timeline.
By default, we use format.frames_per_second / 1, which means 1 PTS tick = 1 frame.
See FIDL's AudioRenderer::SetPtsUnits.
Defined at line 44 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.cc
zx::time ReferenceTimeFromMonotonicTime (zx::time mono_time)Return the time in the current reference clock that corresponds to the given monotonic time.
Defined at line 67 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.cc
void Play (TestFixture * fixture, zx::time reference_time, int64_t media_time)Send a Play command to the renderer and wait until it is processed.
Either time may be NO_TIMESTAMP, as described in the FIDL documentation.
Defined at line 71 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.cc
template <fuchsia::media::AudioSampleFormat SampleFormat>PacketVector AppendSlice (const AudioBuffer<SampleFormat> & buffer, int64_t frames_per_packet, int64_t initial_pts)Overload to help template instantiation.
Defined at line 93 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.h
zx::time PlaySynchronized (TestFixture * fixture, VirtualDevice * output_device, int64_t media_time)Like Play, but aligns the reference_time with the start of output_device's ring buffer.
Returns the reference_time at which the audio will start playing.
Defined at line 98 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.cc
void ClearPayload ()Reset the payload buffer to all zeros and seek back to the start.
Defined at line 105 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.h
std::pair<int64_t, int64_t> Pause (TestFixture * fixture)Send a Pause command to the renderer and wait until it is processed.

std::string reporting_id_str ()For validating properties exported by inspect. This mirrors what is done by class Reporter.
Reporter assigns a distinct 'id' to each renderer (see `next_renderer_id` in reporter.h),
reduces it to a string, and uses it as the node name for metrics reporting purposes.

template <fuchsia::media::AudioSampleFormat SampleFormat>PacketVector AppendPackets (const std::vector<AudioBufferSlice<SampleFormat>> & slices, int64_t initial_pts)Submit the given slices as a sequence of timestamped packets, with one packet per slice.
The packets are appended to the payload buffer. If the packets overrun the end of the buffer,
those extra packets will be queued and submitted once space becomes available in the buffer.
Defined at line 133 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.cc
template <fuchsia::media::AudioSampleFormat SampleFormat>PacketVector AppendSlice (AudioBufferSlice<SampleFormat> slice, int64_t frames_per_packet, int64_t initial_pts)Submit the given slice as a sequence of timestamped packets, with this slice divided into
packets of size frames_per_packet.
Defined at line 165 of file ../../src/media/audio/audio_core/testing/integration/renderer_shim.cc
void WaitForPackets (TestFixture * fixture, const PacketVector & packets, int64_t ring_out_frames)Wait until the given packets are rendered. |packets| must be non-empty and must be ordered by
start_pts. If |ring_out_frames| > 0, we wait for all |packets| to be rendered, plus an
additional |ring_out_frames|.
