I am having trouble rescaling the resolution of a video with complex filters to 720p, adding the scale to reference the video seems to cause an error

error output is [AVFilterGraph # 0x7f964163e9a0] No such filter: ''
Your filtergraph is malformed:
, [va][ovrl0][v0] appears to be a typo and is not applied to any filter.
Your first scale filter is referencing [v0] but [v0] does not exist (other than the orphaned declaration in the typo).
, is use to join linear filters to create a filterchain. ; is used to separate distinct filterchains. You're using , instead of ; in some locations. See FFmpeg Filter Syntax.
I'm guessing you want something like:
-filter_complex \
"[0]scale=1280:720[ovrl0]; \
[1]scale=40:40[ovrl1]; \
[2]scale=40:40[ovrl2]; \

currently i create with imagick (convert -size 640x480 xc:#FF000 hex1.png and hex2.png) 2 png images and save both png files.
now i need the following (but i have no idea how i can do that (maybe ffmpeg?)):
create a video 640x480 for example a length of 10 seconds like this method:
0.00s (hex1) > 0.55s (hex2) > 1.10s (hex1) > 1.65s (hex2) > 2.2s (hex1).... until the 10 seconds has reached.
the hex1 and hex2 images should always morph/fade from hex1 => hex2 => hex1, ...
but the time is very critical. the time must be exact always have 0.55.
maybe i can create on same way direct the HEX colors without creating first a png image for that purposes.
can anybody helps me how i can do that best way?
thank you so much and many greets iceget
currently i have created only a single image with that function:
ffmpeg -loop 1 -i hex1.png -c:v libx264 -t 10 -pix_fmt yuv420p video.mp4
Here is one of the approaches to achieving your goal without pre-creation of images:
ffmpeg -hide_banner -y \
-f lavfi -i color=c=0x0000ff:size=640x480:duration=0.55:rate=20 \
-filter_complex \
"[0]fade=type=out:duration=0.55:color=0xffff00[fade_first_color]; \
[fade_first_color]split[fade_first_color1][fade_first_color2]; \
[fade_first_color1]reverse[fade_second_color]; \
[fade_first_color2][fade_second_color]concat[fade_cycle]; \
[fade_cycle]loop=loop=10/(0.55*2):size=0.55*2*20,trim=duration=10" \
flicker.mp4
Since loop filter operates with frames, not seconds, and you have time constraints, you may choose only the few FPS rates correspondig to the integer number of frames that fit in the 0.55 seconds period (e.g. 20, 40, 60).
The filtergraph is self-explanable.
The result of such command will be like this:
Almost universal way (added in response to the OP's new questions)
#!/bin/bash
# Input parameters
color_1=0x0000ff
color_2=0xffff00
segment_duration=0.55
total_duration=10
# Magic calculations
sd_numerator=${segment_duration#*.}
sd_denominator=$(( 10**${#sd_numerator} ))
FPS=$(ffprobe -v error -f lavfi "aevalsrc=print('$sd_denominator/gcd($sd_numerator,$sd_denominator)'\,16):s=1:d=1" 2>&1)
FPS=${FPS%.*}
# Preparing the output a little bit longer than total_duration
# and mark the cut point with the forced keyframe
ffmpeg -hide_banner -y \
-f lavfi -i color=c=$color_1:size=640x480:duration=$segment_duration:rate=$FPS \
-filter_complex \
"[0]fade=type=out:duration=$segment_duration:color=$color_2[fade_first_color]; \
[fade_first_color]split[fade_first_color1][fade_first_color2]; \
[fade_first_color1]reverse[fade_second_color]; \
[fade_first_color2][fade_second_color]concat[fade_cycle]; \
[fade_cycle]loop=loop=ceil($total_duration/($segment_duration*2))+1: \
size=$segment_duration*2*$FPS,fps=fps=25" \
-force_key_frames $total_duration \
flicker_temp.mp4
# Fine cut of total_duration
ffmpeg -hide_banner -y -i flicker_temp.mp4 -to $total_duration flicker_${total_duration}s.mp4
# Clean up
rm flicker_temp.mp4
I need to trim and merge the video into one. I need to implement a cross fade or any smooth transitioning between each cut. Can I implement and how to implement the xfade or other ffmpeg smooth transition?
I did read this from multiple source.
Merging multiple video files with ffmpeg and xfade filter
But I still fail to generate a working code
Below is the example command and video section that I need to trim

I'm using the current code to create a video with some text of several lines. When executed I'm receiving a video with the text joined vertically because of lacking space. How do I do to add line-height space?
ffmpeg -i videoInput.mp4 \
-vf drawtext="./font/Roboto/Roboto-Bold.ttf: \
text='testing text \ntesting text \ntesting text':\
fontcolor=yellow:\
fontsize=36:\
box=1:\
boxcolor=black#0.5: \
boxborderw=160:\
x=(w-text_w)/2:\
y=(h-text_h)/2"\
-codec:a copy \
videoOutput.mp4
To increase the line-height add a line_spacing parameter to the command,(http://ffmpeg.org/ffmpeg-filters.html#drawtext-1)
So it looks like:
ffmpeg -i videoInput.mp4 \
-vf drawtext="./font/Roboto/Roboto-Bold.ttf: \
text='testing text \ntesting text \ntesting text':\
line_spacing=30:\
fontcolor=yellow:\
fontsize=36:\
box=1:\
boxcolor=black#0.5: \
boxborderw=160:\
x=(w-text_w)/2:\
y=(h-text_h)/2"\
-codec:a copy \
videoOutput.mp4
Or
Some trick is to append a double breakline on the desired text. It would look like:
text='testing text \n\ntesting text \n\ntesting text'
ffmpeg -i videoInput.mp4 \
-vf drawtext="./font/Roboto/Roboto-Bold.ttf: \
text='testing text \n\ntesting text \n\ntesting text':\
fontcolor=yellow:\
fontsize=36:\
box=1:\
boxcolor=black#0.5: \
boxborderw=160:\
x=(w-text_w)/2:\
y=(h-text_h)/2"\
-codec:a copy \
videoOutput.mp4
I created a UDP stream with -f mpegts and some options like -mpegts_transport_stream_id.
I received the stream with "StreamXpert - Real-time stream analyzer" that shows all options are in the output. See my ffmpeg parameters and the StreamXpert at the end.
The same Muxer options seem to be ignored with -f rtp_mpegts.
I have tried to use -f mpegts and pipe it to -f rtp_mpegts like so:
ffmpeg -i ... -f mpegts pipe: | ffmpeg pipe: -c copy -f rtp_mpegts "rtp://239.1.1.9:1234?pkt_size=1316"
The options are still ignored.
This ticket "support options for MPEGTS muxer when using RTP_MPEGTS" also notices the ignored option. Furthermore in this comment, "thovo" gives an analysis and suggests a solution.
Obviously the problem still exists. Anybody found a workaround for this?
My additional question: I have not questioned if my project really needs rtp in the first place. Maybe my coworker didn't know better and requested rtp when udp would be sufficient as well.
The aim was to receive the RTP stream with a TV using DVB via IP. This was successful an a Panasonic TV.
The SAT>IP Specification on page 10 requires rtp for Media Transport:
The SAT>IP protocol makes use of:
UPnP for Addressing, Discovery and Description,
RTSP or HTTP for Control,
RTP or HTTP for Media Transport.
Is udp out of the equation?
