![]() The clip precision will depend on the key-frame interval configuration of the encoder or software encoder, such as Open Broadcast Software (OBS), which can be up to a one second interval. NOTE: This solution uses the PDT information and the byte range manifest, and it parses and retrieves only the group of segments in the interval requested. ![]() The solution parses the original Amazon IVS source playlist manifest and returns a new clipped playlist manifest containing just the media segments of interest. By using this API, created on top of Amazon API Gateway-a fully managed service that makes it easy for developers to create, publish, maintain, monitor, and secure APIs at nearly any scale-and AWS Lambda, a serverless, event-driven compute service, we can create an HTTP request with desired start and end times, as demonstrated in Figure 1. Let’s assume that we have a 100-seconds-long live streaming session, where we want to clip just the most relevant 50 seconds. It means that the segment starts at byte 116,748 and is 68056 bytes long, and the #EXTINF tag, which specifies the segment’s duration, in this case, is one-second long. In a manifest file, it applies only to the following media segment URL. A brief definition of Program-Date-Time (PDT)Īs described in the RFC8216, the embedded time stamp tag EXT-X-PROGRAM-DATE-TIME associates the first sample of a media segment with an absolute date or time, indicating the wall-clock time for every HLS segment produced by using the coordinated universal time (UTC) ISO-8601 format. ![]() By trimming the initial and final parts, developers can remove undesired portions of the recorded live stream, such as when the streamer was live and recording but wasn’t fully ready yet. In this blog, we explore how to use PDT tagging and the byte range manifest to clip content and export the best moments of your live stream. It specifies the start and end byte range for each segment, allowing clients to request only the portion of the media that they need. The byte range manifest is used to divide a media segment file into smaller segments, marked by keyframe intervals. Inside the manifest, each element of an HLS stream has a unique PDT tag that includes the PDT information for each media segment. ![]() The PDT tag is a time stamp embedded in an HLS manifest that is used to indicate the absolute date and time of a particular stream media segment, typically a few seconds long. These features are available when using Auto-Record to Amazon S3, giving developers have access to each archived media segment using the absolute date and time information in the playlist manifest, and additional byte range manifest files. The PDT provides precise presentation timestamps to allow time-synchronized tasks, while the byte range manifest allows detailed segmentation and selective loading of the media content. See Ways to back up or protect your files.Amazon Interactive Video Service (Amazon IVS), a managed live streaming solution that lets users build interactive video experiences, has added HTTP live streaming (HLS) Program-Date-Time (PDT) tags and HLS byte range manifest files. You can use iCloud Drive and iCloud Photos to safely store your documents, photos, and videos in iCloud. With many apps, you can use File > Revert To > Browse All Versions to view previous versions of documents in Time Machine, then find and restore the version you want. For example, if an item was in the Documents folder, it’s returned to the Documents folder. Restored items return to their original location. Select one or more items you want to restore (these can include folders or your entire disk), then click Restore. If you see a pulsing light to semi-dark gray tick mark, it represents a backup that’s still loading or validating on the backup disk. Use the arrows and timeline to browse the local snapshots and backups. A message may appear while your Mac connects to the backup disk. Use Launchpad to view and open apps on Mac and open Time Machine (in the Other folder). If you’re missing an item from the desktop, you don’t need to open a window. On your Mac, open a window for the item you want to restore.įor example, to recover a file you accidentally deleted from your Documents folder, open the Documents folder.
