I need to merge two video files, add a watermaker and a timecode burned in the video.
I see this (by #llogan:)
ffmpeg -i video.mp4 -i audio.mp3 -i watermark.png -filter_complex "[0:v:0]drawtext=fontfile=/usr/share/fonts/TTF/DejaVuSansMono.ttf:timecode='01\:23\:45\:00':r=25:x=(w-text_w)/2:y=h-text_h-20:fontsize=20:fontcolor=white:box=1:boxborderw=4:boxcolor=black[bg];[1][bg]overlay=W-w-10:H-h-12:format=auto[v]" -map "[v]" -map 1:a -shortest output.mp4
But I can't apply for two videos, because of the map. Can someone help me, please? My last attempt was:
ffmpeg -i [video1] -i [video2] -i [image-overlay] -filter_complex "[0:v:0]drawtext=fontfile=/Windows/Fonts/arial.ttf: timecode='00\:00\:00\:00': r=25: x=(w-tw)/2: y=h-(2*lh): fontcolor=0xccFFFF#1: fontsize=85: box=1: boxcolor=0x000000#0.2[bg];concat=n=2:v=1:a=1[vv][a];[vv][2:v]overlay=0:0[v];[vv][bg]overlay=0:0" -map "[v]" -map "[a]" -c:v libx264 -b 2000k -preset fast -c:a aac [output file]
Assuming you want to draw timecode to only video1, and concatenate video1 to video2, and add image overlay over the combined videos:
ffmpeg -i [video1] -i [video2] -i [image-overlay] -filter_complex "[0:v:0]drawtext=fontfile=/Windows/Fonts/arial.ttf: timecode='00\:00\:00\:00': r=25: x=(w-tw)/2: y=h-(2*lh): fontcolor=0xccFFFF#1: fontsize=85: box=1: boxcolor=0x000000#0.2[tc];[tc][0:a][1:v][1:a]concat=n=2:v=1:a=1[cat][a];[cat][2:v]overlay=0:0[v]" -map "[v]" -map "[a]" -c:v libx264 -b:v 2000k -preset fast -c:a aac [output file]

I need to combine this 2 ffmpeg commands:
"-i videoFile.mp4 -c:a copy -c:v libx264 -vf pad=$length:height=$length:x=-1:y=-1:color=#195766 resultFile"
and
"-i videoFile.mp4 -i waterMark.png -filter_complex 'overlay=10:main_h-overlay_h-10' resultFile.mp4"
Is it possible? How result command will look like?
I hope I have got it right...
The combined command is:
ffmpeg -y -i videoFile.mp4 -i waterMark.png -c:a copy -c:v libx264 -filter_complex "[0:v]pad=384:height=216:x=-1:y=-1:color=#195766[t];[t][1:v]overlay=10:main_h-overlay_h-10[v]" -map "[v]" -map 0:a resultFile.mp4
For mobile FFmpeg on android (according to OP's comment):
"-y -i ${videoFile.absolutePath} -i $waterMarkPath -c:a copy -c:v libx264 -filter_complex pad=$length:height=$length:x=-1:y=-1:color=#195766[t];[t][1:v]overlay=10:main_h-overlay_h-10[v] -map [v] -map 0:a ${resultFile.absolutePath}"
I used the following post as reference: Create video with 5 images with fadeIn/out effect in ffmpeg.
Testing:
Creating a sample video file (with audio):
ffmpeg -y -r 25 -f lavfi -i testsrc=size=192x108:rate=30 -f lavfi -i sine=frequency=400 -f lavfi -i sine=frequency=1000 -filter_complex amerge -vcodec libx265 -crf 17 -pix_fmt yuv420p -acodec aac -ar 22050 -t 30 videoFile.mp4
Creating a sample PNG image file:
ffmpeg -y -f lavfi -i mandelbrot=rate=1:size=192x108 -t 1 waterMark.png
Executing the combined command:
ffmpeg -y -i videoFile.mp4 -i waterMark.png -c:a copy -c:v libx264 -filter_complex "[0:v]pad=$length:$length=216:x=-1:y=-1:color=#195766[t];[t][1:v]overlay=10:main_h-overlay_h-10[v]" -map "[v]" -map 0:a resultFile.mp4
Result (first frame of the output of the test):
I am attempting to have multiple output files in ffmpeg map to multiple inputs however instead of each input mapping to a unique output I get the first input mapping to the first video and then the next videos never get created at all, I will describe exactly what I am trying to achieve below,
I need to:
create multiple video output files
from multiple audio input files
which all use the same one common image file to create the
video
I will post my command below, any help would be greatly appreciated thanks
-y -i input1.mp3 -i input2.mp3 -f image2 -loop 1 -r 2 -i imagefile.png -shortest -c:a aac -c:v mpeg4 -crf 18 -preset veryfast -movflags faststart -map 0 output1.mp4 -map1 output2.mp4
Basic command
ffmpeg -i input1.mp3 -i input2.mp3 -loop 1 -framerate 10 -i imagefile.png -map 2:v -map 0:a -vf format=yuv420p -shortest output1.mp4 -map 2:v -map 1:a -vf format=yuv420p -shortest output2.mp4
The video is filtered and encoded once per output.
With the split filter
ffmpeg -i input1.mp3 -i input2.mp3 -loop 1 -framerate 10 -i imagefile.png -filter_complex "[2:v]format=yuv420p,split=outputs=2[v0][v1]" -map "[v0] -map 0:a -shortest -movflags +faststart output1.mp4 -map "[v1]" -map 1:a -shortest -movflags +faststart output2.mp4
The video is filtered once total, and encoded separately for each output.
Pipe
ffmpeg -y -v error -loop 1 -framerate 10 -i imagefile.png -filter_complex "[0:v]format=yuv420p[v]" -map "[v]" -c:v libx264 -f nut - | ffmpeg -y -i - -i input1.mp3 -i input2.mp3 -map 0:v -map 1:a -c:v copy -shortest -movflags +faststart output1.mp4 -map 0:v -map 2:a -c:v copy -shortest -movflags +faststart output2.mp4
The video is filtered and encoded only once and each output stream copies it.
I want to make the different qualities from video in one command.
I used this below code.
But there is an issue,and it's that the output files not have details
ffmpeg -i input.mp4 -filter_complex [0:v]format=yuv420p,split=2[s0][s1];
[s0]scale=hd480[v0];
[s1]scale=nhd[v1]
-map [v0] -map [v1] -map 0:a? -c:v libx264 -c:a aac -f tee -threads 0
"[select='v\:0,a':f=mp4]1/480.mp4|[select='v\:1,a':f=mp4]1/360.mp4"
What I must be do?
With the guidances and helps of #Mulvya the answer is like this :
ffmpeg -i input.mp4 -filter_complex [0:v]format=yuv420p,split=2[s0][s1];
[s0]scale=hd480[v0];
[s1]scale=nhd[v1]
-map [v0] -map [v1] -map 0:a? -c:v libx264 -c:a aac -f tee -flags +global_header -threads 0
"[select='v\:0,a':f=mp4]1/480.mp4|[select='v\:1,a':f=mp4]1/360.mp4"
This works for merging audio and video
ffmpeg -i video.mp4 -i audio.ogg -filter_complex "[0:a][1:a]amerge=inputs=2[a]" -map 0:v -map "[a]" -c:v copy -c:a libvorbis -ac 2 -shortest out.mp4 -y -nostdin
I can't figure out how to delay the audio so it starts x seconds into the video. I have tried -itsoffset but it doesn't work.
Use
ffmpeg -i video.mp4 -i audio.ogg -filter_complex "[1:a]adelay=1000|1000[a1];[0:a][a1]amerge=inputs=2[a]" -map 0:v -map "[a]" -c:v copy -c:a libvorbis -ac 2 -shortest out.mp4 -y -nostdin
The adelay adds 1000 ms of silence to both channels of the OGG.
This is more of a workaround, but you could concatenate 1 second of silence with your ogg first:

I am having trouble combining these 3 passes in ffmpeg into a single process.
Is this even possible?

Join filters with a comma and filterchains with a semicolon:
