Video Optimizer allows mobile application developers to test the network performance of video, images and other files for compression, speed, battery drain and other aspects of performance.

The Data Collector is the component of the Video Optimizer application that captures the data traffic of a mobile device and stores that information in trace files that can be analyzed using the Video Optimizer Data Analyzer.

The Video Optimizer Data Analyzer is the component of the Video Optimizer application that evaluates the trace data collected from an application and generates statistical and analytical results based on recommended best practices.

This Open Source Code Package contains all of the code needed to build both of these Video Optimizer components.

Video Optimizer 4.1 Features

• This release brings to the Linux version all the following features and enhancements that were brought to the Mac and PC version in release 4.1:

• Analysis of IPV6 data is now supported, increasing the number of apps that allow full video stream analysis.

• Capture of IPV6 data by the VPN collector is now supported, allowing analysis of IPV6 data from Android devices.

• New Segment Progress graph in the Video tab displays the download time progress and the play time progress of the segments.

  • Video segments, Audio segments, Video PlayTime, and Audio PlayTime are displayed for demuxed video.
  • Download_Progress and PlayTime_Progress are displayed for muxed video.
  • Hovering over the points displays the following information - Segment #, Track #, Download Start Time, Download End Time, Play Start Time, Play End Time, Duration, Progress, and the Content (Video/Audio).
  • Graph refreshes when each stream is selected.

• New Segment Buffer graph displays information about the playback buffer.

  • Hovering over the points in the graph displays the following information – Segment #, PlayBack Buffer in seconds, and the TimeStamp.
  • The graph refreshes when each selected stream has its startup delay set.

• Redesigned Startup Delay window

  • In the User Touch Event section, navigate through the touch events viewing the simultaneously changing frame images on the right-hand side of the dialog to choose the time stamp of the precise video playback requested time.
  • In the Video Startup Time section, navigate through the startup times viewing the simultaneously changing frame images on the right-hand side of the dialog to set the video startup time to any value greater than the Play requested time
  • Video Startup Time is now saved: Once the startup delay has been set for a stream/streams, the values for the play requested time and the startup delay are saved in a json file in the trace folder. When the trace is opened again, these previously set values are displayed when the Startup Delay window opens for the stream.

• CSI (Chunk Sequence Inferencer) - the CSI feature can be used for analysis if the default video analysis does not provide any results and a manifest is available.

• User Interface Enhancements:

  • A clearer message ‘Video segments could not be assigned to a Video Stream’, when there are video requests, but no Streams showing in video tab.
  • Enhanced ffmpeg and ffprobe detection.
  • Enhanced Content View tab which displays all the requests and responses in the same order as in Request/Response View.
  • Enhanced handling of 0 value for throttling and stopping data flow during trace collection.

Known issues in Release 4.1

• Startup Delay window does not display the Set/Cancel button if the vertical resolution of the display is below 1080. Work around is to capture landscape orientation traces for video.
• Trace collection cannot be started when the device is on the lock screen, otherwise the VPN collector app will freeze.
