class VideoBitrateAllocation

Defined at line 23 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.h

Class that describes how video bitrate, in bps, is allocated across temporal

and spatial layers. Note that bitrates are NOT cumulative. Depending on if

layers are dependent or not, it is up to the user to aggregate.

void ~VideoBitrateAllocation ()

Defined at line 30 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.h

void VideoBitrateAllocation (Bitrate::Mode mode)

Defined at line 39 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.cc

bool SetBitrate (size_t spatial_index, size_t temporal_index, int32_t bitrate_bps)

Deleted variants: you must SAFELY convert to uint32_t before calling.

See base/numerics/safe_conversions.h for functions to safely convert

between types.

bool SetBitrate (size_t spatial_index, size_t temporal_index, int64_t bitrate_bps)

Defined at line 48 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.h

bool SetBitrate (size_t spatial_index, size_t temporal_index, uint64_t bitrate_bps)

Defined at line 51 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.h

bool SetBitrate (size_t spatial_index, size_t temporal_index, uint32_t bitrate_bps)

Returns true iff. the bitrate was set (sum within uint32_t max value). If

a variable bitrate is used and the previous peak bitrate was below the new

sum of bitrates across layers, this will automatically set the new peak to

equal the new sum. If you have a signed or 64-bit value you want to use as

input, you must explicitly convert to uint32_t before calling. This is

intended to prevent implicit and unsafe type conversion.

Defined at line 72 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.cc

bool SetPeakBps (uint32_t peak_bps)

True iff. this bitrate allocation can have its peak set to |peak_bps| (the

peak must be greater than the sum of the layers' bitrates, and the bitrate

mode must be variable bitrate).

bool operator!= (const VideoBitrateAllocation & other)

Defined at line 78 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.h

uint32_t GetBitrateBps (size_t spatial_index, size_t temporal_index)

Returns the bitrate for specified spatial/temporal index, or 0 if not set.

Defined at line 94 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.cc

uint32_t GetSumBps ()

Sum of all bitrates.

Defined at line 101 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.cc

uint32_t GetPeakBps ()

Returns peak bitrate.

Defined at line 105 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.cc

const Bitrate GetSumBitrate ()

Non-layered bitrate allocation. If there are layers, this bitrate's target

bps equals the sum of the layers' bitrates.

Defined at line 109 of file ../../src/media/third_party/chromium_media/media/base/video_bitrate_allocation.cc

Bitrate::Mode GetMode ()

Returns the encoding rate control mode of this allocation.
