NAME
Paws::MediaConvert::Mp4Settings
USAGE
This class represents one of two things:
Arguments in a call to a service
Use the attributes of this class as arguments to methods. You shouldn't make instances of this class. Each attribute should be used as a named argument in the calls that expect this type of object.
As an example, if Att1 is expected to be a Paws::MediaConvert::Mp4Settings object:
$service_obj->Method(Att1 => { AudioDuration => $value, ..., Mp4MajorBrand => $value });Results returned from an API call
Use accessors for each attribute. If Att1 is expected to be an Paws::MediaConvert::Mp4Settings object:
$result = $service_obj->Method(...);
$result->Att1->AudioDurationDESCRIPTION
These settings relate to your MP4 output container. You can create audio only outputs with this container. For more information, see https://docs.aws.amazon.com/mediaconvert/latest/ug/supported-codecs-containers-audio-only.html#output-codecs-and-containers-supported-for-audio-only.
ATTRIBUTES
AudioDuration => Str
Specify this setting only when your output will be consumed by a downstream repackaging workflow that is sensitive to very small duration differences between video and audio. For this situation, choose Match video duration (MATCH_VIDEO_DURATION). In all other cases, keep the default value, Default codec duration (DEFAULT_CODEC_DURATION). When you choose Match video duration, MediaConvert pads the output audio streams with silence or trims them to ensure that the total duration of each audio stream is at least as long as the total duration of the video stream. After padding or trimming, the audio stream duration is no more than one frame longer than the video stream. MediaConvert applies audio padding or trimming only to the end of the last segment of the output. For unsegmented outputs, MediaConvert adds padding only to the end of the file. When you keep the default value, any minor discrepancies between audio and video duration will depend on your output audio codec.
CslgAtom => Str
When enabled, file composition times will start at zero, composition times in the 'ctts' (composition time to sample) box for B-frames will be negative, and a 'cslg' (composition shift least greatest) box will be included per 14496-1 amendment 1. This improves compatibility with Apple players and tools.
CttsVersion => Int
Ignore this setting unless compliance to the CTTS box version specification matters in your workflow. Specify a value of 1 to set your CTTS box version to 1 and make your output compliant with the specification. When you specify a value of 1, you must also set CSLG atom (cslgAtom) to the value INCLUDE. Keep the default value 0 to set your CTTS box version to 0. This can provide backward compatibility for some players and packagers.
FreeSpaceBox => Str
Inserts a free-space box immediately after the moov box.
MoovPlacement => Str
If set to PROGRESSIVE_DOWNLOAD, the MOOV atom is relocated to the beginning of the archive as required for progressive downloading. Otherwise it is placed normally at the end.
Mp4MajorBrand => Str
Overrides the "Major Brand" field in the output file. Usually not necessary to specify.
