Abstract: Systems, apparatus, and methods for selectively parsing a live stream for a connected device. GoPro® cameras capture 2 video streams for every recording: a main resolution video (MRV) and a frame aligned low-resolution video (LRV). Currently, the LRV is streamed to other devices for playback in real-time. Unfortunately, not all devices in the mobile ecosystem can keep up with these transfer and playback speeds of the LRV; thus, exemplary embodiments of the present disclosure pick frames from the LRV to provide an IDR-only version that can be replayed with minimal processing burden. As a related issue, operating codecs in parallel at different resolutions can result in misaligned frame structures since each codec independently determines its “group of pictures” (GOP), etc. The described techniques define a frame correspondence that can also be used to improve post-processing at best effort.
