aarch64 : vp9 : use alternative returns in the core loop filter function
14 novembre 2016, par Janne Grunauaarch64 : vp9 : use alternative returns in the core loop filter function
Since aarch64 has enough free general purpose registers use them to
branch to the appropiate storage code. 1-2 cycles faster for the
functions using loop_filter 8/16, ... on a cortex-a53. Mixed results
(up to 2 cycles faster/slower) on a cortex-a57. -
Video Encode different parts of video using different bitrates
8 février 2015, par khateebIf I’ve a video like : video-lectures
And I need to encode the slides with high bitrate (as it’s the most important to the user) and encode the rest of the view with low bitrate.
-
Select the part to encode with high bitratre.
-
Separately Encoding the different parts with different bitrates.
- Combine the different parts into one video.
The purpose is to reduce the total file-size to be published online, hence reduce the bandwidth needed.
I need to do that using ffmpeg.
I’ll use that approach in encoding video-lectures recorded with still camera (180 degree view like the images above), since I know which regions are more useful to students (board and slides) than other regions. -
