WMSPanel collected data about more than 13 billion views.

We've added a new metric - total view time for our server products. It's nearly 1.7 billion this quarter, or 18+ million view hours per day.

fMP4 ABR HLS for VOD AVC and HEVC streaming in Nimble Streamer

Last year Apple announced their support for fragmented MP4, or fMP4, in HTTP Live Streaming protocol. This enables HLS carry the content without traditional MPEG-2 Transport Stream container, which allows reducing the traffic by removing MPEGTS overhead.
The traffic saving is more than 10%, with 15%-20% on average. The all-favorite Big Buck Bunny showed 13% saving on using fMP4 compared to MPEGTS.

Nimble Streamer already had fMP4 support for live streaming, now we introduce fragmented MP4 support for VOD HLS.

This container supports H.264/AVC and H.265/HEVC video, with AAC, MP3 and AC-3 audio.


The setup for Nimble Streamer VOD streaming routes is made the same way as before, you can read this article for all details. The only difference is in the playback URL. Instead of "playlist.m3u8" name you will use "playlist_fmp4.m3u8" like this:
When accessing the stream using that type of URL, the content will be automatically re-packaged on-the-fly to provide it in fMP4 container and the playlist will be made using proper standard.

The same applies to ABR streaming with SMIL files. You can set up ABR VOD HLS using SMIL and then use "playlist_fmp4.m3u8" file name like this:
This URL will also generate proper playlist and chunklists.


The fMP4-based playlist generated by Nimble Streamer will look as follows.

H.264/AVC playlist for fMP4:
H.265/HEVC playlist for fMP4:

The chunks list will be made the same way.

All Nimble HLS fMP4 streams can be played in latest versions of Apple's operating systems as well as in ffplay and JWPlayer. If you know of any other players or platforms, please share your comment about it.

If you have any questions regarding this feature set, please contact our helpdesk.

Live Transcoder wildcard scenarios

Live Transcoder for Nimble Streamer is a powerful tool for easy transformation of your live content. One of its most popular cases is creating multiple renditions from single input which is used for ABR live streaming setup.

To process multiple streams, you typically need to specify a new scenario for every transcoded stream, this means you need to have a set of decoders, filters and encoders for each.
Even though Live Transcoder has a very convenient and easy-to-use drag-n-rop UI, this may be annoying for setting up big amount of streams.

This is why we have wildcard capabilities in transcoding scenarios:

  1. You may specify just application name as a baseline for separating different types of scenarios.
  2. For each incoming stream in this application, its stream name will be taken as is and it will be used for output stream names.
