ffmpeg multiple text/logo elements
17 septembre 2018, par omega1I am trying to add multiple items to an ffmpeg command and am getting stuck.
So far in the command I am automatically updating one image, which I’m using as a video, I also want to add a logo and two lines of text.
I have been successful until the last item, which is the logo overlay.
This is the relevant part of code :
ffmpeg \
-f image2 -loop 1 \
-y \
-i "/var/www/html/image_rotate.png" \
-re \
-i audio.mp3 \
-vf "movie=/var/www/html/overlay_logo.png [watermark]; [in][watermark] overlay=0:0 [out], drawtext=fontsize=10:fontfile=/var/www/html/OpenSans-Regular.ttf:textfile=/var/www/html/text1.txt:box=1:boxcolor=#000000:fontcolor=#FFFFFF:x=0:y=(h-text_h-20):reload=1, drawtext=fontsize=10:fontfile=/var/www/html/OpenSans-Regular.ttf:textfile=/var/www/htmltext2.txt:box=1:boxcolor=#000000:fontcolor=#FFFFFF:x=0:y=(h-text_h-30)" \This gives me the following error :
Simple filtergraph ... was expected to have exactly 1 input and 1 output. However, it had >1 input(s) and >1 output(s). Please adjust, or use a complex filtergraph (-filter_complex) instead.
If I remove the last part I added (the overlay logo) I do not get the error.
If I add multiple -vf it only processes one (the text OR the logo).I’m not sure how to achieve this.

Detect frames that have a given image/logo with FFmpeg
7 juillet 2022, par sccI'm trying to split a video by detecting the presence of a marker (an image) in the frames. I've gone over the documentation and I see
removelogo
but notdetectlogo
.


Does anyone know how this could be achieved ? I know what the logo is and the region it will be on.



I'm thinking I can extract all frames to png's and then analyse them one by one (or n by n) but it might be a lengthy process...



Any pointers ?
