Video Optimizer FAQs
Why does AT&T care about optimizing applications (and why should I care)?
Our customers expect a fast network and blazing-fast speeds. By helping applications reduce their impact on the network, we can continue to provide that level of service.
Optimizing your app is a bit like getting in the carpool lane during rush-hour: You get to where you're going that much faster, and everyone else experiences a little less gridlock
When I open a trace file in the AT&T Video Optimizer that I captured using Wireshark, it does not display network traffic data. What's wrong?
AT&T Video Optimizer does not currently support pcap.ng (PCAP Next Generation) files, and cannot display network traffic data from files in this format. The most recent versions of Wireshark (1.7 and up), contain a new version of the Dumpcap tool that captures packet data in the pcap.ng format by default, instead of the pcap format, as previous versions did. To use Wireshark to capture data that it is compatible with the Video Optimizer, you must specify the flag '-P'.
Does AT&T Video Optimizer provide a way to identify potential security threats in my application code?
Yes. AT&T Video Optimizer is able to look for basic data transmission security issues. You can learn more with our best practices.
Why does the AT&T Video Optimizer appear to hang while opening the file from the long trace session that I captured with data from my favorite application?
Application traces that contain large network bursts, like those that can occur when capturing a long session with complex mapping applications or rich social media applications, may take an extremely long time to load in Video Optimizer. This issue is caused by the complex algorithms that are used to calculate the analysis of the burst data, and is not an issue with available memory. In these cases, Video Optimizer may appear to hang, but will eventually load the trace analysis.
Can I contribute to the AT&T Video Optimizer Project?
Yes, we would love that! Please fork and contribute to our open source AT&T Video Optimizer repository on Github. We want to see what you can do!
Can I use the AT&T Video Optimizer to analyze a Packet Capture (Pcap) file?
In addition to the Trace files captured by Video Optimizer, Video Optimizer also allows you to analyze Pcap files that have been captured using a program like Wireshark or Windows Network Monitor. When you open the "File" menu of the Data Analyzer, you will see options for "Open Trace" and "Open Pcap File". For more information on opening a trace file in Video Optimizer for analysis, please refer to the Video Optimizer Testing Guide.
