![]() ![]() Literally ‘coder-decoder’ or ‘compressor-decompressor,’ codecs apply algorithms to the video and create a miniature version of it. Versatile Video Coding, or VVC, is also H.266 for the same reason.”įor the sake of clarity, I’ll be including both names at first mention of each codec within the subsections of this article. “H.264/AVC and H.265/HEVC have two names because each codec was standardized by both MPEG and the International Telecommunication Union (ITU). H.264, also known as AVC (Advanced Video Coding), is the most common video codec AAC (Advanced Audio Coding) is the most common audio codec.īut wait - why does H.264 also go by AVC? And how are we to sort through so many confusing acronyms? Streaming codec expert Jan Ozer explains it: Streaming requires the use of both audio and video codecs. Codecs allow us to tightly compress bulky streams down for delivery and storage. What Is a Codec?Ĭontent distributors use a video compression technology called a codec to shrink videos into a streamable size. To put it more simply: encoding describes the process of compression, whereas codecs describe the means for doing so. In order to compress the raw video into a more manageable size, encoders use video and audio codecs, which apply algorithms to shrink the bulky video for delivery. Popular software options include Vmix, Wirecast, and the free-to-use OBS Studio. Video encoding is essential to live streaming, helping to ensure quick delivery and playback.Įncoding can occur within a browser or mobile app, on an IP camera, using software, or via a stand-alone appliance. When it comes to streaming, videos are often compressed from gigabytes of data down to megabytes of data. Video encoding refers to the process of converting raw video into a digital format that’s compatible with many devices. These properties are available for collection in the newest SDKs for Mux-Embed Player, Shaka Player, AVPlayer, HLS.js Player, Dash.js Player, and Roku. The data can be found in the API, exports, and the Mux Dashboard by going to a View page and it will be shown in the error box on the top of the page. Error Context can be set by the SDK as player_error_context to provide additional error instance-specific information that will not impact the default error aggregation.Custom Dimensions: For customers with Media contracted plans, you may now use up to 10 custom dimensions.It is available from the API in the Video View properties as view_drm_type. The value is found in the Mux Dashboard by going to a View page and looking for “DRM Type” in the “Video Metadata” section. It can be specified and collected by the SDK at view start using the view_drm_type metadata. DRM Type allows you to track the DRM component used to secure your video.It is also available from the API in the Video View properties as view_dropped_frame_count. The value can be found in the Mux Dashboard by going to a View page and looking for “Dropped Frame Count” in the “View” section. Frame Drops track the number of frames that are not shown during playback.The full list of changes include the following: This information can be found via Mux Dashboard, Mux Data API, or View Streaming Exports. ![]() You can now collect and see additional information for each view in Mux Data. Improvement Data SDK Mux Data now supports collecting Frame Drops, DRM used, Error context, and additional customer metadata Most views that resume after an hour should now be considered new views and have different view_ids associated with them if you are on the latest SDKs. The changes to the metrics are available in the Mux Dashboard and View Streaming Export. Other metrics will be slightly impacted too for the same reason. The improvement also allows you to gain access to the pre-paused section of the view, which previously was not possible.Īs a result of this roll-out, you may notice that the total view count has a 0.5% - 1% decline, and the Playback Failure Percentage will have a small decline, typically in the range of 0.03 to 0.3 points, thanks to eliminating the double counting issue. This fixed a double-counting issue on the pre-paused section of the view which later paused more than an hour and then resumed. Mux Data has rolled out fixes and improvements for counting views that paused for an hour without sending any heartbeat. ![]() Improvement Data Improved accuracy of data for long-resumed views in Mux Data ![]()
