PRESTOplay for GStreamer

Choose different algorithms and manage parameters to control adaptive bitrates.

Our range of PRESTOplay SDKs feature a common API for consistent playback behavior and simplified maintenance across different player platforms and devices. Common settings include: player configuration, UI, ABR algorithm, latency, and subtitles.

Allows content representation exclusion. Our player checks a user device’s resolution capability and ignores ABR renditions that aren’t supported. For example, if you offer UHD quality but a user’s smartphone only supports HD, then the player will automatically exclude the UHD rendition (as long as there’s also an HD rendition available). The user receives the best quality available on their device, and you save on bandwidth for unsupported stream qualities.

Automated recovery from connectivity loss with separate configuration for manifests, chunks, and other parameters.

Accounts for non-standard manifest or MP4 files to ensure playback. Our low-level API allows us to add fixes to the player in case you have content not conforming to specifications. This is useful in case you’re dealing with non-spec conforming content libraries that you can’t update easily.

We provide simplified user interface tools including easily configurable buttons, subtitles, and thumbnail views.

A common player API that ensures audio/subtitle tracks and video quality representations are exposed in the same way, independent of the content format (MPEG-DASH, Smooth Streaming, HLS). This saves time by allowing you to build a user interface once, independent of the actual streaming format.

We enable protected HLS content using Google’s Widevine DRM system (where HLS content uses the fMP4 container format).

Allows a single content file-set to be used for playback as either MPEG-DASH or HLS formats as needed. DRM can also be used with the single file-set on devices/platforms supporting the AES-CBC encryption mode.

Playback capable of <1 second latency behind the live edge.

We also enable managed latency by defining a live edge latency goal to synchronize all players instances for similar playback timing. For example: a football game where all users see a goal at the same time by accounting for playback drift.

Enable stream downloading for secure local offline playback. Manifests can be accessed to transfer content to a user’s device with the video quality, audio, and subtitle track able to be specified. Content is downloaded with no transmuxing or transcoding to maintain video quality. DRM licenses are also stored securely: both during download and on a user’s device, your content remains protected.

Lets users switch streams as fast as broadcast TV. Avoid buffer delay by pre-caching neighboring content including pre-fetching licenses for a quick low-latency user experience.

Enables multi-speed fast forward, rewind, and slow. We support two trick play modes:

Decoder mode: Speed up playback by downloading and showing all frames. This creates a smooth experience, but isn’t ideal at high speeds due to decoder/bandwidth limitations. You can’t rewind with this mode.

Seek mode: Our player continuously seeks, forward or backwards, based on the playback speed. This mode performs better at high speeds (> 6x) since you only need one frame at given time intervals. I-frame tracks are typically used here to reduce segment sizes and allow faster seeking.

If you’d like to avoid VMAP, you can use our API to manually set when ads are played within the playback timeline.
