Hello everyone.
I've been having some problems with recording video from an IP camera
that transmits a live feed over RTSP. I've searched a lot for potential
solutions, but none helped so far. I've been going crazy trying to fix
this for days, so now I'm asking here as a last resort.
This is
Here's some additional information that may or may not be useful in
solving this:
1. I removed the "+genpts+igndts+ignidx" from "fflags". From what I
could understand, it wasn't necessary to use them, and removing them
didn't make anything better or worse.
2. I tried to find out why the vide
After another day of searching for solutions, I finally managed to come
up with one. Remember I said that "-use_wallclock_as_timestamps 1" fixes
the sync issues but causes the video to stutter? So I attempted to fix
the stuttering with the following filter:
setts='max(floor(PTS/X)*X,if(N,PREV
ull -
And no, putting "scale_vaapi" before overlay here does not help.
P.S. I'm wondering if this recommendation was written by AI, by the way.

Thanks for the link. Unfortunately, that seems to be only tangentially
related

I suspect colorspace, so try explicitly set on input (or convert)
colorspace maybe... There is a lot of options -vf, -pix_fmt, -sws_flags
etc. you can test - find them on ffmpeg wiki here

Hi Vladimir,
I see on previous posts that resolutions are different, but also frame
rates are different and colour spaces (bt709 vs "") are different.
Are you really sure the prob
Greetings everyone.
I am attempting to overlay 2 video streams in real-time with QuickSync
hardware acceleration. I want to use both hardware decode and encode to
make the most use out of the GPU and avoid excessive CPU usage.
I've found an example command-line here:
