Instances
newCmafGroupSettings :: CmafGroupSettings Source #
Create a value of CmafGroupSettings
with all optional fields omitted.
Use generic-lens or optics to modify other optional fields.
The following record fields are available, with the corresponding lenses provided for backwards compatibility:
$sel:additionalManifests:CmafGroupSettings'
, cmafGroupSettings_additionalManifests
- By default, the service creates one top-level .m3u8 HLS manifest and one
top -level .mpd DASH manifest for each CMAF output group in your job.
These default manifests reference every output in the output group. To
create additional top-level manifests that reference a subset of the
outputs in the output group, specify a list of them here. For each
additional manifest that you specify, the service creates one HLS
manifest and one DASH manifest.
$sel:baseUrl:CmafGroupSettings'
, cmafGroupSettings_baseUrl
- A partial URI prefix that will be put in the manifest file at the top
level BaseURL element. Can be used if streams are delivered from a
different URL than the manifest file.
$sel:clientCache:CmafGroupSettings'
, cmafGroupSettings_clientCache
- Disable this setting only when your workflow requires the
#EXT-X-ALLOW-CACHE:no tag. Otherwise, keep the default value Enabled
(ENABLED) and control caching in your video distribution set up. For
example, use the Cache-Control http header.
$sel:codecSpecification:CmafGroupSettings'
, cmafGroupSettings_codecSpecification
- Specification to use (RFC-6381 or the default RFC-4281) during m3u8
playlist generation.
$sel:destination:CmafGroupSettings'
, cmafGroupSettings_destination
- Use Destination (Destination) to specify the S3 output location and the
output filename base. Destination accepts format identifiers. If you do
not specify the base filename in the URI, the service will use the
filename of the input file. If your job has multiple inputs, the service
uses the filename of the first input file.
$sel:destinationSettings:CmafGroupSettings'
, cmafGroupSettings_destinationSettings
- Settings associated with the destination. Will vary based on the type of
destination
$sel:encryption:CmafGroupSettings'
, cmafGroupSettings_encryption
- DRM settings.
$sel:fragmentLength:CmafGroupSettings'
, cmafGroupSettings_fragmentLength
- Specify the length, in whole seconds, of the mp4 fragments. When you
don't specify a value, MediaConvert defaults to 2. Related setting: Use
Fragment length control (FragmentLengthControl) to specify whether the
encoder enforces this value strictly.
$sel:imageBasedTrickPlay:CmafGroupSettings'
, cmafGroupSettings_imageBasedTrickPlay
- Specify whether MediaConvert generates images for trick play. Keep the
default value, None (NONE), to not generate any images. Choose Thumbnail
(THUMBNAIL) to generate tiled thumbnails. Choose Thumbnail and full
frame (THUMBNAIL_AND_FULLFRAME) to generate tiled thumbnails and
full-resolution images of single frames. When you enable Write HLS
manifest (WriteHlsManifest), MediaConvert creates a child manifest for
each set of images that you generate and adds corresponding entries to
the parent manifest. When you enable Write DASH manifest
(WriteDashManifest), MediaConvert adds an entry in the .mpd manifest for
each set of images that you generate. A common application for these
images is Roku trick mode. The thumbnails and full-frame images that
MediaConvert creates with this feature are compatible with this Roku
specification:
https://developer.roku.com/docs/developer-program/media-playback/trick-mode/hls-and-dash.md
$sel:imageBasedTrickPlaySettings:CmafGroupSettings'
, cmafGroupSettings_imageBasedTrickPlaySettings
- Tile and thumbnail settings applicable when imageBasedTrickPlay is
ADVANCED
$sel:manifestCompression:CmafGroupSettings'
, cmafGroupSettings_manifestCompression
- When set to GZIP, compresses HLS playlist.
$sel:manifestDurationFormat:CmafGroupSettings'
, cmafGroupSettings_manifestDurationFormat
- Indicates whether the output manifest should use floating point values
for segment duration.
$sel:minBufferTime:CmafGroupSettings'
, cmafGroupSettings_minBufferTime
- Minimum time of initially buffered media that is needed to ensure smooth
playout.
$sel:minFinalSegmentLength:CmafGroupSettings'
, cmafGroupSettings_minFinalSegmentLength
- Keep this setting at the default value of 0, unless you are
troubleshooting a problem with how devices play back the end of your
video asset. If you know that player devices are hanging on the final
segment of your video because the length of your final segment is too
short, use this setting to specify a minimum final segment length, in
seconds. Choose a value that is greater than or equal to 1 and less than
your segment length. When you specify a value for this setting, the
encoder will combine any final segment that is shorter than the length
that you specify with the previous segment. For example, your segment
length is 3 seconds and your final segment is .5 seconds without a
minimum final segment length; when you set the minimum final segment
length to 1, your final segment is 3.5 seconds.
$sel:mpdManifestBandwidthType:CmafGroupSettings'
, cmafGroupSettings_mpdManifestBandwidthType
- Specify how the value for bandwidth is determined for each video
Representation in your output MPD manifest. We recommend that you choose
a MPD manifest bandwidth type that is compatible with your downstream
player configuration. Max: Use the same value that you specify for Max
bitrate in the video output, in bits per second. Average: Use the
calculated average bitrate of the encoded video output, in bits per
second.
$sel:mpdProfile:CmafGroupSettings'
, cmafGroupSettings_mpdProfile
- Specify whether your DASH profile is on-demand or main. When you choose
Main profile (MAIN_PROFILE), the service signals
urn:mpeg:dash:profile:isoff-main:2011 in your .mpd DASH manifest. When
you choose On-demand (ON_DEMAND_PROFILE), the service signals
urn:mpeg:dash:profile:isoff-on-demand:2011 in your .mpd. When you choose
On-demand, you must also set the output group setting Segment control
(SegmentControl) to Single file (SINGLE_FILE).
$sel:ptsOffsetHandlingForBFrames:CmafGroupSettings'
, cmafGroupSettings_ptsOffsetHandlingForBFrames
- Use this setting only when your output video stream has B-frames, which
causes the initial presentation time stamp (PTS) to be offset from the
initial decode time stamp (DTS). Specify how MediaConvert handles PTS
when writing time stamps in output DASH manifests. Choose Match initial
PTS (MATCH_INITIAL_PTS) when you want MediaConvert to use the initial
PTS as the first time stamp in the manifest. Choose Zero-based
(ZERO_BASED) to have MediaConvert ignore the initial PTS in the video
stream and instead write the initial time stamp as zero in the manifest.
For outputs that don't have B-frames, the time stamps in your DASH
manifests start at zero regardless of your choice here.
$sel:segmentControl:CmafGroupSettings'
, cmafGroupSettings_segmentControl
- When set to SINGLE_FILE, a single output file is generated, which is
internally segmented using the Fragment Length and Segment Length. When
set to SEGMENTED_FILES, separate segment files will be created.
$sel:segmentLength:CmafGroupSettings'
, cmafGroupSettings_segmentLength
- Specify the length, in whole seconds, of each segment. When you don't
specify a value, MediaConvert defaults to 10. Related settings: Use
Segment length control (SegmentLengthControl) to specify whether the
encoder enforces this value strictly. Use Segment control
(CmafSegmentControl) to specify whether MediaConvert creates separate
segment files or one content file that has metadata to mark the segment
boundaries.
$sel:segmentLengthControl:CmafGroupSettings'
, cmafGroupSettings_segmentLengthControl
- Specify how you want MediaConvert to determine the segment length.
Choose Exact (EXACT) to have the encoder use the exact length that you
specify with the setting Segment length (SegmentLength). This might
result in extra I-frames. Choose Multiple of GOP (GOP_MULTIPLE) to have
the encoder round up the segment lengths to match the next GOP boundary.
$sel:streamInfResolution:CmafGroupSettings'
, cmafGroupSettings_streamInfResolution
- Include or exclude RESOLUTION attribute for video in EXT-X-STREAM-INF
tag of variant manifest.
$sel:targetDurationCompatibilityMode:CmafGroupSettings'
, cmafGroupSettings_targetDurationCompatibilityMode
- When set to LEGACY, the segment target duration is always rounded up to
the nearest integer value above its current value in seconds. When set
to SPEC\\_COMPLIANT, the segment target duration is rounded up to the
nearest integer value if fraction seconds are greater than or equal to
0.5 (>= 0.5) and rounded down if less than 0.5 (< 0.5). You may need to
use LEGACY if your client needs to ensure that the target duration is
always longer than the actual duration of the segment. Some older
players may experience interrupted playback when the actual duration of
a track in a segment is longer than the target duration.
$sel:videoCompositionOffsets:CmafGroupSettings'
, cmafGroupSettings_videoCompositionOffsets
- Specify the video sample composition time offset mode in the output fMP4
TRUN box. For wider player compatibility, set Video composition offsets
to Unsigned or leave blank. The earliest presentation time may be
greater than zero, and sample composition time offsets will increment
using unsigned integers. For strict fMP4 video and audio timing, set
Video composition offsets to Signed. The earliest presentation time will
be equal to zero, and sample composition time offsets will increment
using signed integers.
$sel:writeDashManifest:CmafGroupSettings'
, cmafGroupSettings_writeDashManifest
- When set to ENABLED, a DASH MPD manifest will be generated for this
output.
$sel:writeHlsManifest:CmafGroupSettings'
, cmafGroupSettings_writeHlsManifest
- When set to ENABLED, an Apple HLS manifest will be generated for this
output.
$sel:writeSegmentTimelineInRepresentation:CmafGroupSettings'
, cmafGroupSettings_writeSegmentTimelineInRepresentation
- When you enable Precise segment duration in DASH manifests
(writeSegmentTimelineInRepresentation), your DASH manifest shows precise
segment durations. The segment duration information appears inside the
SegmentTimeline element, inside SegmentTemplate at the Representation
level. When this feature isn't enabled, the segment durations in your
DASH manifest are approximate. The segment duration information appears
in the duration attribute of the SegmentTemplate element.
cmafGroupSettings_additionalManifests :: Lens' CmafGroupSettings (Maybe [CmafAdditionalManifest]) Source #
By default, the service creates one top-level .m3u8 HLS manifest and one top -level .mpd DASH manifest for each CMAF output group in your job. These default manifests reference every output in the output group. To create additional top-level manifests that reference a subset of the outputs in the output group, specify a list of them here.
