Variable resolution in video file containers like mp4, mkv
15 novembre 2022, par Artem SuprunovI need to make an application that gets media data from some proprietary system and save to files mkv and mp4, on user's choice. In that system resolution of video frames may vary (for instance, 1920x1080, 1280x720 etc.). My question is whether it's possible to have in that containers a video track with variable resolution ?


I'm going to use ffmpeg libs C api, but if it has design limitations that don't allow to change resolution on fly, then I'll have to implement own muxers, but firstly need to find out if it's possible n terms of the containers format, at least one of them.

Cortex-A7 instruction cycle timings
15 mai 2014, par Mans — ARMThe Cortex-A7 ARM core is a popular choice in low-power and low-cost designs. Unfortunately, the public TRM does not include instruction timing information. It does reveal that execution is in-order which makes measuring the throughput and latency for individual instructions relatively straight-forward. The table below lists the measured issue cycles … Continue reading
