Member Data Documentation

◆ bandwidth

uint32_t shaka::StreamDescriptor::bandwidth = 0

Optional user-specified content bit rate for the stream, in bits/sec. If specified, this value is propagated to the $Bandwidth$ template parameter for segment names. If not specified, its value may be estimated.

Definition at line 101 of file packager.h.

◆ drm_label

std::string shaka::StreamDescriptor::drm_label

Specifies a custom DRM stream label, which can be a DRM label defined by the DRM system. Typically values include AUDIO, SD, HD, UHD1, UHD2. If not provided, the DRM stream label is derived from stream type (video, audio), resolutions etc.

Definition at line 93 of file packager.h.

◆ hls_group_id

std::string shaka::StreamDescriptor::hls_group_id

Required for audio when outputting HLS. It defines the group ID for the output stream. This is used as the GROUP-ID attribute for EXT-X-MEDIA.

Definition at line 111 of file packager.h.

◆ hls_iframe_playlist_name

std::string shaka::StreamDescriptor::hls_iframe_playlist_name

Optional for HLS output. It defines the name of the I-Frames only playlist for the stream. For Video only. Usually ends with .m3u8.

Definition at line 117 of file packager.h.

◆ hls_name

std::string shaka::StreamDescriptor::hls_name

Required for audio when outputting HLS. It defines the name of the output stream, which is not necessarily the same as output. This is used as the NAME attribute for EXT-X-MEDIA.

Definition at line 108 of file packager.h.

◆ hls_playlist_name

std::string shaka::StreamDescriptor::hls_playlist_name

Required for HLS output. It defines the name of the playlist for the stream. Usually ends with .m3u8.

Definition at line 114 of file packager.h.

◆ language

std::string shaka::StreamDescriptor::language

Optional value which contains a user-specified language tag. If specified, this value overrides any language metadata in the input stream.

Definition at line 104 of file packager.h.

◆ output

std::string shaka::StreamDescriptor::output

Specifies output file path or init segment path (if segment template is specified). Can be empty for self initialization media segments.

Definition at line 79 of file packager.h.

◆ output_format

std::string shaka::StreamDescriptor::output_format

Optional value which specifies output container format, e.g. "mp4". If not specified, will detect from output / segment template name.

Definition at line 85 of file packager.h.

◆ skip_encryption

bool shaka::StreamDescriptor::skip_encryption = false

If set to true, the stream will not be encrypted. This is useful, e.g. to encrypt only video streams.

Definition at line 88 of file packager.h.

◆ stream_selector

std::string shaka::StreamDescriptor::stream_selector

Stream selector, can be audio, video, text or a zero based stream index. Required.

Definition at line 75 of file packager.h.

◆ trick_play_factor

uint32_t shaka::StreamDescriptor::trick_play_factor = 0

If set to a non-zero value, will generate a trick play / trick mode stream with frames sampled from the key frames in the original stream. trick_play_factor defines the sampling rate.
