What is the version of your FFmpeg? Your command work for me with the latest
FFmpeg (https://git.ffmpeg.org/gitweb/ffmpeg.git/shortlog/refs/heads/master).
There is a green line at the bottom of each scaled image with your command, you
may try vpp_qsv instead of scale_qsv. We will fix the green line issue in
scale_qsv

Thanks

[FFmpeg-user] how to set the color background when i use overlay_qsv

2022-01-26 Thread zha...@bstar.com.cn

hello:
I want to splice four or more video into one video，i want to set the 
background to a fixed size and the color is black, so i must scale the image 
then overlay. 

My environment is ubuntu and I used command is:

ffmpeg -i h1.mp4 -i h2.mp4 -i h3.mp4 -i h4.mp4 -filter_complex 
"color=c=black:s=1920x1080[bg];[0:v]scale=iw/2:-1[img0];[1:v]scale=iw/2:-1[img1];[2:v]
 
scale=iw/2:-1[img2];[3:v]scale=iw/2:-1[img3];[bg][img0]overlay=shortest=1[out0];[out0][img1]overlay=shortest=1:x=w[out1];[out1][img2]overlay=shortest=1:y=h[out2];[out2][img3]overlay=shortest=1:x=w:y=h"
 -y out.mp4

-
the comman is correct,but when i change it to qsv. It's not working correctly:

./ffmpeg -hwaccel qsv -c:v h264_qsv -i h1.mp4 -hwaccel qsv -c:v h264_qsv -i 
h2.mp4 -hwaccel qsv -c:v h264_qsv -i h3.mp4 -hwaccel qsv -c:v h264_qsv -i 
h4.mp4 -filter_complex "color=black:r=30:size=1920x1080:sar=1/1,

It is still true that hosters that require registration (or only work
with Windows browsers) likely will be ignored.

thanks for the tip - i've been looking into this and not understanding 
how to accomplish it

for bash the command is stty and it seems the relevant options are:
ixany
ixoff
ixon

what i don't understand is 1) which one(s) to use and 2) how to use them 
in a shell script; should this be near the top of the script so it's 
global, or should these options be enabled/disabled as needed per-command?

This is not a problem with ffmpeg. You should configure your shell to

is there a way to have ffmpeg exit gracefully when the pipe is broken?

Again, it is not ffmpeg's responsibility:

Does the error disappear if you don't use "-s" if you are using "filter_complex"
(as you have to)?

"-f mpegts" looks strange in this command line (but that may only be me).

[FFmpeg-user] Ubuntu 21.10 ffmpeg 4.4 compile- libzmq3-dev fail

2022-01-26 Thread Matt C

Not sure if the is a libzmq or ffmpeg issue...
On Ubuntu 21.10 while compiling ffmpeg 4.4 and trying to include
--enable-libzmq
FFmpeg cannot find libzmq and is specifically looking for: libzmq 4.2.1 even 
when I have
sudo apt-get install libzmq3-dev
This does not happen on Ubuntu 20.04.
The only way I could get libzmq to work was to use gcc 9, get 
zeromq-4.2.1.tar.gz
./autogen.sh ./configure make sudo make install
That let ffmpeg compile but it was messing everything else up so that is not a 
solution.
Only other info I could find was here, looks like this has maybe happened 
before?
https://github.com/conda-forge/zeromq-feedstock/issues/16

Thanks!
