Functions§

codec_utils_aac_caps_set_level_and_profile: Sets the level and profile on caps if it can be determined from audio_config. See codec_utils_aac_get_level() and codec_utils_aac_get_profile() for more details on the parameters. caps must be audio/mpeg caps with an “mpegversion” field of either 2 or 4. If mpegversion is 4, the “base-profile” field is also set in caps.
codec_utils_aac_get_channels: Returns the channels of the given AAC stream.
codec_utils_aac_get_index_from_sample_rate: Translates the sample rate to the index corresponding to it in AAC spec.
codec_utils_aac_get_level: Determines the level of a stream as defined in ISO/IEC 14496-3. For AAC LC streams, the constraints from the AAC audio profile are applied. For AAC Main, LTP, SSR and others, the Main profile is used.
codec_utils_aac_get_profile: Returns the profile of the given AAC stream as a string. The profile is normally determined using the AudioObjectType field which is in the first 5 bits of audio_config
codec_utils_aac_get_sample_rate: Translates the sample rate index found in AAC headers to the actual sample rate.
codec_utils_aac_get_sample_rate_from_index: Translates the sample rate index found in AAC headers to the actual sample rate.
codec_utils_av1_create_av1c_from_caps: Creates the corresponding AV1 Codec Configuration Record
codec_utils_av1_create_caps_from_av1c: Parses the provided av1c and returns the corresponding caps
codec_utils_av1_get_level: Transform a seq_level_idx into the level string
codec_utils_av1_get_seq_level_idx: Transform a level string from the caps into the seq_level_idx
codec_utils_caps_from_mime_codec: Converts a RFC 6381 compatible codec string to gst::Caps. More than one codec string can be present (separated by ,).
codec_utils_caps_get_mime_codec: Converts caps to a RFC 6381 compatible codec string if possible.
codec_utils_h264_caps_set_level_and_profile: Sets the level and profile in caps if it can be determined from sps. See codec_utils_h264_get_level() and codec_utils_h264_get_profile() for more details on the parameters.
codec_utils_h264_get_level: Converts the level indication (level_idc) in the stream’s sequence parameter set into a string. The SPS is expected to have the same format as for codec_utils_h264_get_profile().
codec_utils_h264_get_level_idc: Transform a level string from the caps into the level_idc
codec_utils_h264_get_profile: Converts the profile indication (profile_idc) in the stream’s sequence parameter set into a string. The SPS is expected to have the following format, as defined in the H.264 specification. The SPS is viewed as a bitstream here, with bit 0 being the most significant bit of the first byte.
codec_utils_h264_get_profile_flags_level: Parses profile, flags, and level from a H264 AVCC extradata/sequence_header. These are most commonly retrieved from a video/x-h264 caps with a codec_data buffer.
codec_utils_h265_caps_set_level_tier_and_profile: Sets the level, tier and profile in caps if it can be determined from profile_tier_level. See codec_utils_h265_get_level(), codec_utils_h265_get_tier() and codec_utils_h265_get_profile() for more details on the parameters.
codec_utils_h265_get_level: Converts the level indication (general_level_idc) in the stream’s profile_tier_level structure into a string. The profiel_tier_level is expected to have the same format as for codec_utils_h264_get_profile().
codec_utils_h265_get_level_idc: Transform a level string from the caps into the level_idc
codec_utils_h265_get_profile: Converts the profile indication (general_profile_idc) in the stream’s profile_level_tier structure into a string. The profile_tier_level is expected to have the following format, as defined in the H.265 specification. The profile_tier_level is viewed as a bitstream here, with bit 0 being the most significant bit of the first byte.
codec_utils_h265_get_tier: Converts the tier indication (general_tier_flag) in the stream’s profile_tier_level structure into a string. The profile_tier_level is expected to have the same format as for codec_utils_h264_get_profile().
codec_utils_h266_caps_set_level_tier_and_profile: Sets the level, tier and profile in caps if it can be determined from decoder_configuration. See codec_utils_h266_get_level(), codec_utils_h266_get_tier() and codec_utils_h266_get_profile() for more details on the parameters.
codec_utils_h266_get_level: Converts the level indication (general_level_idc) in the stream’s ptl_record structure into a string.
codec_utils_h266_get_level_idc: Transform a level string from the caps into the level_idc
codec_utils_h266_get_profile: Converts the profile indication (general_profile_idc) in the stream’s ptl_record structure into a string.
codec_utils_h266_get_tier: Converts the tier indication (general_tier_flag) in the stream’s ptl_record structure into a string.
codec_utils_mpeg4video_caps_set_level_and_profile: Sets the level and profile in caps if it can be determined from vis_obj_seq. See codec_utils_mpeg4video_get_level() and codec_utils_mpeg4video_get_profile() for more details on the parameters.
codec_utils_mpeg4video_get_level: Converts the level indication in the stream’s visual object sequence into a string. vis_obj_seq is expected to be the data following the visual object sequence start code. Only the first byte (profile_and_level_indication) is used.
codec_utils_mpeg4video_get_profile: Converts the profile indication in the stream’s visual object sequence into a string. vis_obj_seq is expected to be the data following the visual object sequence start code. Only the first byte (profile_and_level_indication) is used.
codec_utils_opus_create_caps: Creates Opus caps from the given parameters.
codec_utils_opus_create_caps_from_header: Creates Opus caps from the given OpusHead header and comment header comments.
codec_utils_opus_create_header: Creates OpusHead header from the given parameters.
codec_utils_opus_parse_caps: Parses Opus caps and fills the different fields with defaults if possible.
codec_utils_opus_parse_header: Parses the OpusHead header.
encoding_list_all_targets: List all available EncodingTarget for the specified category, or all categories if categoryname is None.
encoding_list_available_categories: Lists all EncodingTarget categories present on disk.
pb_utils_add_codec_description_to_tag_list
pb_utils_add_codec_description_to_tag_list_for_tag
pb_utils_get_caps_description_flags: Returns flags that describe the format of the caps if known. No flags are set for unknown caps.
