ffmpeg multiple text/logo elements

I 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.

When you need to work with multiple streams while filtering, the recommended method is to use a filter_complex.

ffmpeg \
    -loop 1 \
    -i "/var/www/html/image_rotate.png" \
    -i "/var/www/html/overlay_logo.png" \
    -i audio.mp3 \
    -filter_complex "[0][1]overlay=0:0,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)" \
    -y \
    -shortest \

The logo is now fed as a regular input.
