void H264SPS ()

Defined at line 104 of file ../../src/media/third_party/chromium_media/media/video/h264_parser.cc

void GetLevelConfigFromProfileLevel (VideoCodecProfile profile, uint8_t level, int * level_idc, bool * constraint_set3_flag)

Get corresponding SPS |level_idc| and |constraint_set3_flag| value from

requested |profile| and |level| (see Spec A.3.1).

std::optional<gfx::Size> GetCodedSize ()

Based on T-REC-H.264 7.4.2.1.1, "Sequence parameter set data semantics",

available from http://www.itu.int/rec/T-REC-H.264.

Defined at line 110 of file ../../src/media/third_party/chromium_media/media/video/h264_parser.cc

std::optional<gfx::Rect> GetVisibleRect ()

Also based on section 7.4.2.1.1.

Defined at line 132 of file ../../src/media/third_party/chromium_media/media/video/h264_parser.cc

VideoColorSpace GetColorSpace ()

Based on T-REC-H.264 E.2.1, "VUI parameters semantics",

available from http://www.itu.int/rec/T-REC-H.264.

Defined at line 187 of file ../../src/media/third_party/chromium_media/media/video/h264_parser.cc

uint8_t GetIndicatedLevel ()

Helper to compute indicated level from parsed SPS data. The value of

indicated level would be included in H264LevelIDC enum representing the

level as in name.

Defined at line 198 of file ../../src/media/third_party/chromium_media/media/video/h264_parser.cc

bool CheckIndicatedLevelWithinTarget (uint8_t target_level)

|target_level|.
