Thank you. Adding the fps filter solved my problem.

Hello,
I heard from 1 of the people that do HW reviews that AMD was considering
implementing their very own RTX and looking at what people think of RTX.
I created a poll on LQ:

I got the same result.
Here a video where you can see how the music accelerates and then the
latency goes to 0 (What I hope is that when the connection is stabilized
again, the latency will remain at 600ms.)

Hi Ted,
Thanks again for all your suggestions. Ok, I will try to get this delay with a
file, or something like that.
I'm curious though, what happens function / command wise when you hit the pause
key because this ends up producing the results I'm looking for. When you hit
the pause key and

thanks for your hints. Unfortunately they have been already known to

ohhh wait. SDL gives you a hw surface to draw on if I understand correctly? So
it will happily gobble up frames and draw them fast as it can whenever it
Hi Ted,
Thank you - I definitely appreciate all of the suggestions. It seems like with
the cue filter, frames are getting buffered and then at the end of the start
delay, they all play through really quickly. It makes me wonder if there isn't
some index that needs to be updated to basically
Thanks very much.
I was hoping to restrict the output using ffmpeg and not ffprobe; mostly so I
could make a proxy with overlay and metadata text file at the same time.
My question regarding bit depth was because the filter doc shows values between
0-255 which is cool for 8bit values, but

In order to show specific entries with signal stats, I have used the
following.
input=[file to process]
ffprobe -f lavfi movie=$input,signalstats -show_entries
frame=pkt_pts_time:frame_tags=lavfi.signalstats.YDIF:frame_tags=lavfi.signalstats.VDIF:frame_tags=lavfi.signalstats.UDIF

The 8bit values appear to be covered, but I am not sure how to get 10bit or
higher.
The filter works with inputs up to 16 bit depth.

Hi
Is it possible to limit the return of signalstats filter to only return certain
values (YMAX, YMIN etc) instead of always outputting all values.
Perhaps only output values if they are outside of a tolerance eg <16 or >235
The other question regarding this filter, can it output 10bit values?

Hello everyone! I'm encoding video to MPEG-2 using Zeranoe's Windows builds.
The source file is 720p 60fps, progressive. I want to keep high quality and
compatibility with DVD standards, so I use:
ffmpeg -hwaccel auto -i "input" -vf scale=ntsc,interlace,fps=fps=29.97 -c:v
mpeg2video -q:v 3
On the receiver side, set the latency around 600ms
