Let's say I have 20 different online stream videos (playlist.m3u8) and I want every video to output to their own .avi files. How can I do that in single file, so I don't have to download and convert every single one separately?
I found a -map command online, but didn't get straight answer to this.
Will this be a working code?
ffmpeg -i 1playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 0 1.avi \
-i 2playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 1 2.avi \
-i 3playlist.m3u8 -vf scale=768:-1 -vcodec libx264 -crf 24 -acodec copy -map 2 3.avi

I am using an ffmpeg complex filter to:
turn a number of images into a slideshow
scale the slideshow to 1/6th of its original size
loop the slideshow infinitely
set the looping slideshow as a picture-in-picture over another looping video
then add audio from another file which determines the maximum length of the final video.
Everything is working except step 3.
Here is my code (broken down into individual lines):
ffmpeg -y
-loop 1 -t 5.5 -i /uploads/2021/07/slide04-scaled.jpg
-loop 1 -t 5.5 -i /uploads/2021/07/Slide05-scaled.jpg

Use -stream_loop to loop intro.mp4
The loop filter needs you to tell it how many frames to loop.
xfade offers more transition effects and eliminates the need for additional setpts and overlay. To figure out offset timing see Merging multiple video files with ffmpeg and xfade filter.
I am attempting to use ffmpeg exe to combine 2 video files and 1 audio. I wanted the audio to play over "inputFile.mp4" and not over the "outroFile.mp4" is this possible? Currently this is what I have. But Im not sure if what im doing wrong or what I need to get it right.
ffmpeg -i "inputFile.mp4" -i "outroFile.mp4" -i "audioFile.mp3" -threads 4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] [2:v:0] [2:a:0] concat=n=3:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" "outputFile.mp4"
Can you please help me with this?
This can be done in two steps.
#1
ffmpeg -i "inputFile.mp4" -stream_loop -1 -i "audioFile.mp3" -map 0:v -map 1:a -c copy -shortest inputwithaudio.mp4
#2
ffmpeg -i inputwithaudio.mp4 -i outrofile.mp4 -threads 4 -filter_complex "[0:v:0] [0:a:0] [1:v:0] [1:a:0] concat=n=2:v=1:a=1 [v] [a]" -map "[v]" -map "[a]" "outputFile.mp4"
You'll need a recent version of ffmpeg, preferably 4.0, as there's a bug with stream_loop in earlir versions.
I've got these sentences of code that I use for video processing, the first one adds a watermark, the second creates a .ts file of the watermarked video and then adds an intro and outro to it but I found that it quickly fills disk space because of the .ts files being used, is there a way to achieve the same results without them? Either by deleting them right after using them or by using a different process altogether.
for %%I in ("C:\Users\Administrator\Desktop\work\*.mp4") do ffmpeg.exe

pause
This does it in one command, with no intermediate files.
for %%I in ("C:\Users\Administrator\Desktop\work\*.mp4") do ffmpeg.exe
-y -i "%%I" -i white.png -i out1.ts -filter_complex "[1:v][0:v]scale2ref=iw/6:ih/18[logo][0v];[0v][logo]overlay=W-w-3:H-h-1,scale=hd720,setsar=1[vl];[2:v][2:a][vl][0:a][2:v][2:a]concat=n=3:v=1:a=1[v][a]"
-map "[v]" -map "[a]" -r 20 -c:v libx264 -ar 48000 "C:\Users\Administrator\Desktop\Complete-videos\%%~nI.mp4"
pause
Notes: Depending on where out1.ts is, you may have to specify its full path during input. In the first command, in your 2nd step, the size option has no effect as you're copying streams. If resize is needed, insert scale=hd720 after the concat filter in my command. Add -strict experimental if your ffmpeg is older than Dec 2015 and you don't want to upgrade.
[totally untried suggestion since I have no idea what the ffmpeg line is doing]
I suggest you try this on a small file subset on a device with a restricted space like a ramdrive or a usb drive. USB drive may take a while. Coffee is good.
for %%I in ("C:\Users\Administrator\Desktop\work\*.mp4") do (
ffmpeg.exe -y -i "%%I" -i white.png -filter_complex "[0:v]scale=iw:ih[v0];[1:v][v0]scale2ref=iw/6:ih/18[logo][0v];[0v][logo]overlay=W-w-3:H-h-1[v]"

This way, the first loop using %%I selects the file to be processed and apparently puts the processed file in another directory then immediately performs the second process on that file, controlled by %%Q using the name in %%~nI to select the single file created by the previous process.
Consequently, instead of processing 10 files each with its own .ts set, one is processed at a time and only one .ts set is created. I don't know whether the second process deletes the .ts files, but I've added a del to get rid of them on each cycle. I've also no idea whether the first process creates the .ts files, but I've made that assumption.
As the educationalists said about "new maths" - it's the idea that's important.
I have this batch script running perfectly on Windows:
C:\ffmpeg\bin\ffmpeg -i http://ipaddress/stream -deinterlace -c:v libx264 -pix_fmt yuv420p -s 960x540 -preset superfast -vb 1200k -maxrate 1200k -r 30 -g 60 -bufsize 8000k -c:a aac -b:a 64k -ar 44100 -ac 2 -f flv rtmp://ipaddress/live/
Sometimes ffmpeg crashes, how can I edit the batch script or what can i add to the batch file to restart the stream.
Thanks advance!
I don't know if the ffmpeg command can be restarted this way,
but I would limit the number of retries to avoid endless loops on fails:
#Echo off
Setlocal EnableDelayedExpansion
Set Retry=0
:loop
C:\ffmpeg\bin\ffmpeg.exe -i http://ipaddress/stream ^
-deinterlace -c:v libx264 -pix_fmt yuv420p -s 960x540 -preset superfast ^
-vb 1200k -maxrate 1200k -r 30 -g 60 -bufsize 8000k -c:a aac -b:a 64k ^
-ar 44100 -ac 2 -f flv rtmp://ipaddress/live/ ^
||(Set /A "Retry+=1"&if !Retry! leq 3 Goto :loop)
I'm converting webm to mp4 using FFmpeg.
My batch file is
cd "C:\Users\Matt\Desktop\" && for %f in (*.webm) do ffmpeg -y -i "C:\Users\Matt\Desktop\%~f" -vcodec libx264 -b:v 600K -pass 1 -acodec aac -b:a 128k "C:\Users\Matt\Desktop\%~nf.mp4" && ffmpeg -y -i "C:\Users\Matt\Desktop\" -vcodec libx264 -b:v 600K -pass 2 -acodec aac -b:a 128k "C:\Users\Matt\Desktop\%~nf.mp4"
It works for CRF and 1 Pass, but using 2 Pass it stops on the second pass and gives the error:
C:\Users\Matt\Desktop" -vcodec libx264 -b:v 600K -pass 2 -acodec aac -b:a 128k C:\Users\Matt\Desktop\video: Invalid argument
The first double quote is missing on the Path, and the filename "video 01.mp4" is cut off.
Your code could only work in cmd directly, in a batch you have to double the percent signs of the for variable.
There is no need for a one liner in a batch.
I hope this is more clear and works.
