Hi
I try to put on the text image.
ffmpeg -re -rtsp_transport tcp -i
rtsp://admin:x@192.168.2.25:554/Streaming/Channels/1 -f image2 -loop
1 -i C:\k\v\T\A.bmp -filter_complex "overlay=10:10" -vcodec libx264
-pix_fmt yuv420p -f flv rtmp://a.rtmp.youtube.com/live2/x-x-x-x
the image file
$ ... -f wav pipe:3 -f wav pipe:4 3>fifo1 4>fifo2
That's impossible since:
pipe:1 stdout
pipe:2: sterr
pipe:0 stdin
I got it working this way:

The only thing have left is the video representation of the audio, which is
a bonus to my sleep recorder experimental

You can tell ffmpeg to "overwrite" them by using "-y". It should just
reuse them, not actually delete them and replace them with files.
(Works for me.)

Hi, we are also streaming a Hikvision cctv camera to youtube. We're not
putting text on the image but are using the "-vf curves" command to
eliminate fog. The CPU was unable to do the curves filter at 30fps above
1080p. We put my GeForce 1060 3GB in the computer, and it doesn't use much

This method results in a 25 fps stream,

Why should it do
fifo1 and fifo2 are not really pipes or fifo-s
This way it asks me if I want to overwrite them:
#!/bin/bash
set -x
mkfifo fifo1 2>/dev/null
mkfifo fifo2 2>/dev/null
ffmpeg -f alsa -i hw:0,0 -f wav fifo1 -f wav fifo2
exit 0

You're creating the same fifo twice, by the way

Hi Carl,
thanks for the quick reply. I did also try the internal aac encoder but still
have the same issue….seems for some reason that the audio track end up being
longer than the video (even if I use the -shortest cmd)
Here my console output

Hello,
I'm using the silencedetect filter for a project, and I've been using an
amplitude ratio for the threshold (i.e., n=), but I'm not sure what this
actually refers to. My guess is that it's a percentage of the peak
amplitude in the file (e.g., 0.01 is 1% of the highest amplitude), but

Hi ffmpeg users,
I’m having a little issue that I hope someone can help me with.
I use FFmpeg to create an x264 mov file in which I add silence audio in it.
When I look at the result, everything seem fine except from the fact that with
frames are add at the end of the encode. From what I
Hi,
As for the documentation I should be able to produce more than 2 outputs at
the same time. The streaming is ok, but the recordings never gets segmented
if I pull this script every five minutes with cron.
Here is my /etc/ffserver.conf file:

Hi All,
I'd like to send my laptop's sound to 2 fifo-s at the same time in order to
read from that fifos later. For some reason if I read from those fifos,
nothing happens:
ffmpeg -i fifo1 -s 0 -t 5 out1.wav
ffmpeg -i fifo2 -s 0 -t 5 out2.wav
This is how I create the 2 fifos:

Afaict, because the file has broken timestamps.
The most important question would be how it
