lavc/opusdsp: simplify R-V V postfilter
16 December 2023, by Rémi Denis-Courmontlavc/opusdsp: simplify R-V V postfilter
This skips the round-trip to scalar register for the sliding 'x'
coefficients, improving performance by about 5%. The trick here is that
the vector slide-up instruction preserves elements in destination vector
until the slide offset.The switch from vfslide1up.vf to vslideup.vi also allows the elimination
of data dependencies on consecutive slides. Since the specifications
recommend sticking to power of two offsets, we could slide as follows:vslideup.vi v8, v0, 2
vslideup.vi v4, v0, 1
vslideup.vi v12, v8, 1
vslideup.vi v16, v8, 2However in the device under test, this seems to make performance slightly
worse, so this is left for (in)validation with future better hardware. -
Expand (extend) a video to an specific duration
8 February 2013, by BorrajaXDo VLC or FFmpeg (or AVconv) have any feature to force the duration of a video to a certain number of seconds?
Let's say I have a... 5 minutes .mp4 video (without audio). Is there a way to have any of the aforementioned tools "expanding" the video to a longer duration? The video comes from a Power Point slideshow, but it's too short (running too fast, to say so). The idea would be automatically inserting frames so it reaches an specified duration. It looks like something pretty doable (erm... for a total newbie in video encoding/transcoding as I am): A 5 minutes video, at 30fps means I have 9000 frames... To make it be 10 times longer, get the first "real" frame, copy it ten times, then get the second "real" frame, copy it ten times... and so on.
I'm using Ubuntu 12.04, but I can install/compile any required software, if needed. So far, I have VLC, AVConv and FFmpeg (FFmpeg in an specific folder, so it won't conflict with AVConv)
Thank you in advance.
