The AV Platform allows you to test audio video across different use cases such as media, entertainment, gaming, and video conferencing. Run tests on OTT media devices. Test DRM-protected content. Perform audio testing across use cases like voice activation and speaker-based applications.
A high resolution camera is placed opposite the device being tested. This camera captures video and the captured content is continuously tested for its quality
The audio from the device under test is captured through microphones and Bluetooth (if enabled) and can be analyzed via HeadSpin's audio match analysis
Blurriness, Blockiness, Brightness, Colorfulness, Contrast, Blur, Exposure, Flickering, Freezing, etc.
Video Frame Rate Drops, Loading/Buffering Time
Reference-free video MOS
VMAF-based full reference video MOS
Audio match analysis
WebRTC support
Accurately measure perceptual video quality
Mean Opinion Score (MOS) quantifies subjective perception of video content using a single number
Traditional approaches using video quality metrics or reference videos do not accurately predict perceptual video quality in gaming scenarios or for live content where no reference video is available
HeadSpin’s reference-free video MOS is based on a supervised learning AI model calibrated against real user experiences and it pools thousands of subjective quality scores on diverse video content for improved DRM video testing.
Frequently Asked Questions
Q1. What are some critical KPIs to test audio video content?
Ans: To test audio video, QA teams aim to capture vital metrics that impact the overall quality of the audio and video content, thereby affecting the user experience. Some of these metrics or KPIs include:
Completion rate
Time spent
Loading/buffering time
Audio match analysis
Frame rate drops
Q2. Why is cross-device testing crucial in audio video test?
Ans: Cross-device testing ensures that the audio/video components of the application work seamlessly across different devices, operating systems, and browsers. This helps in delivering a consistent user experience.
Q3. What are the vital testing requirements for an effective video testing strategy?
Ans: With diverse video streaming applications, video testing needs to cover certain essential tests that include:
Functional testing to double-check elements against their functional requirements
Localization testing to ensure the app meets country- and region-specific expectations
Usability testing to identify potential issues from the user's perspective
Payment testing to verify seamless payment processes for apps with subscription options
Negative testing to evaluate if the app can handle incorrect input and unexpected user behavior
