With all else being equal, a device with a fast Wi-Fi connection should be expected to show a higher quality video stream than a device with a slow connection. The team decided we would revisit HLS when we support longer videos in the future. We chose a progressive download instead of HLS as the video delivery mechanism. For this reason, we will change the video quality only at the start of a video playback. Because the videos are so brief, we believe that changing video quality in the midst of playback would result in a jarring member experience. For reasons like these, it is important that the video delivery be adaptive to dynamic network conditions.įirst-party LinkedIn videos are relatively short-less than 30 seconds long. Network utilization, which affects network speed, can vary from hour to hour. A device may drop out of 4G coverage and fall back to a slower cell tower. Mobile connection bandwidth often fluctuates across locations and time of day. To support the many LinkedIn app teams, we have built a shared native video player library that will power video viewing experiences across our apps. The video viewing experience is also highly sensitive to spotty network coverage and occasionally unreliable connections often seen in mobile networks. Mobile constraintsĬompared to text and images, video transmissions require a lot more data bandwidth and can become costly to our members who are on metered data plans. ![]() This library powers the video viewing experience on LinkedIn. In this post, we will discuss some of the technical challenges involved in developing a shared video player library for Android. We recently launched a feature where members can hear directly from Influencers on timely and thought-provoking topics through the rich experience of video. At LinkedIn, we recognize that video has become a popular medium for people to communicate and share information. ![]()
