I am using FFMPEG to convert all kind of media files to mp3. Files are being Converted Perfectly.
But files give error MPEG HEADER 30 is missing at 31576bytes. In All converted files I see this. And On Some MP3 Players, It do not play.
Here is my conversion Command what i use
$bitrate = '128k';
$command = "ffmpeg -i /home/musicupl/public_html/musicuploads/SavetoAccount/abc.mp4 -ar 44100 -ac 2 -b:a ".$bitrate." -acodec libmp3lame /home/musicupl/public_html/musicuploads/SavetoAccount/Output.mp3;
Is there any more tag to add MPEG Headers during the conversion. I have researched on this and found the -acodec libmp3lame but still same issue.
Is there any other way or attribute to add in command line.
I'm trying to convert a video that lives on my server from a .webm to a .mp4.
shell_exec('ffmpeg -i file.webm output.mp4');
However, this results in an empty mp4 (0 bytes - or, sometimes, and very weirdly, 28 bytes.) The input file exists, and is 45MB.
This answer recommended explicitly copying the input codec, but same result.
shell_exec('ffmpeg -i file.webm -vcodec copy -acodec-copy output.mp4');
What am I doing wrong?
[ ===== EDIT ===== ]
After trying a few more things, inspired by the comments, I'm still having no joy converting to MP4.
It seems I'm running FFMPEG v.2.8.15. This seems quite a lot lower than the current release of 4~, however I only installed this a week or so ago so I'm not sure why this is the case and I don't know how to update it (I'm on WHM Cpanel.)
Anyway, my problem is NOT to do with pathing, because the same command works fine if I change .mp4 to .webm - I get a successfully converted .webm file.
But when I run:
$foo = shell_exec('ffmpeg -i file.webm -vcodec copy -acodec copy output3.mp4 -report');
...I get this FFMPEG log output.
I've also tried:
shell_exec('ffmpeg -fflags +genpts -i file.webm -r 24 KKK.mp4 -report');
...from this answer, and
shell_exec('ffmpeg -i file.webm -c:v copy III.mp4');
...from this article.
Both result in the same problem, i.e. an 0-bytes .mp4 file.
Problem
You're trying to mux VP9 video and Opus audio into the MP4 container. Currently, muxing Opus into the MP4 container is considered experimental and requires -strict experimental (or -strict -2), but your ffmpeg is too old to support that. Download a new version.
Solutions
Do not mux typical WebM formats (VP9 or VP8 + Opus or Vorbis) into MP4. You can re-encode it to H.264 (or H.265) with AAC audio if you want a more common set of formats for MP4:
ffmpeg -i input -c:v libx264 -c:a aac -movflags +faststart output.mp4
Or upgrade your ffmpeg and add the -strict experimental (or -strict -2) output option to your command if you know you want VP9 + Opus in MP4:
ffmpeg -i input -c copy -strict experimental -movflags +faststart output.mp4
Or don't re-mux into MP4 in the first place. HTML5 video supports VP9 + Opus in WebM so just use the original file if it is supported by your target browser(s).
I am creating a video from images using ffmpeg. I am using a file that contains the list of images as
file 'C:\wamp64\www\test\public\userFolder\media\nature3.jpg'
file 'C:\wamp64\www\test\public\userFolder\media\img_001.jpg'
file 'C:\wamp64\www\test\public\userFolder\media\img_003.jpg'
file 'C:\wamp64\www\test\public\userFolder\media\img_006.jpg'
file 'C:\wamp64\www\test\public\userFolder\media\nature3.jpg'
file 'C:\wamp64\www\test\public\userFolder\media\nature4.jpg'
I am using the following command to create video
ffmpeg.exe -y -r 1/10 -f concat -safe 0 -i "imagepaths.txt" -c:v libx264 -s 920x640 "Jawedout.mp4"
The video is being created but the start of video is blank. The video show dark black screen for few secs then show the first image mentioned in file.
However, if the change the command to
ffmpeg.exe -y -f concat -safe 0 -i "imagepaths.txt" -c:v libx264 -vf "fps=25,format=yuv420p" -s 920x640 "Jawedout.mp4"
Then in video I am not seeing first image and last image.
I need to covert 720p or 1080p video to 480p mp4 video , i found below code
ffmpeg -i input -vf scale=-1:480 -vcodec mpeg4 -qscale 3 output.mp4
and please help me , i am unable to give it INPUT VIDEO ex.
$video='/path/to/mp4/video';
exec('ffmpeg -i $video -vf scale=-1:480 -vcodec mpeg4 -qscale 3 output.mp4');
why above code is not working
i used that code and it worked flawless. maybe you werent in the dir with the vid files? or something? you should replace YOURVID.mkv with your file OR /path/to/your/file.mkv as well as replace /path/to/output.mkv with the file name or a file path to the converted output 480p file. easiest thing to do though is be in the dir with the original 720p/1080p video and just use the filename.mkv then output it to that same dir by just using an output.file.name.mkv and not a path. then all files will be in that one directory. i may have over explained it. sorry. lol. and THANK YOU for posting this. it did, indeed, work great for me on my freebsd machine with ffpmeg installed.
ffmpeg -i YOURVID.mkv -vf scale=-1:480 -vcodec mpeg4 -qscale 3 /path/to/new/output.mp4
I have an old 32bit Intel Atom Acer netbook, its not much good for anything. I have batocera installed on it and i need 480p video to play on it.
P.S. with a 320GB HDD, the prev mentioned netbook, some retro game roms and some 480p video files makes an excellent mobile entertainment center.
Let's say I have 10 images and I want to combine those images in a video like a slideshow.
For example I want to show each image for 5 seconds and then continue with next image for another 5 seconds.
If it's possible, it will be perfect to include music and some descriptive text too.
Is there a sample code for this may be with ffmpeg library ?
My first thought was to shell out to the ffmpeg command with something like this.
Creating a Video from Images
ffmpeg can be used to stitch several images together into a video.
There are many options, but the following example should be enough to
get started. It takes all images that have filenames of
XXXXX.morph.jpg, where X is numerical, and creates a video called
"output.mp4". The qscale option specifies the picture quality (1 is
the highest, and 32 is the lowest), and the "-r" option is used to
specify the number of frames per second.
ffmpeg -r 25 -qscale 2 -i %05d.morph.jpg output.mp4
(The website that this blurb was taken from is gone. Link
has been removed.)
Where 25 means 25 images per second. You could set this to 1 for a slight (1 sec) delay or use decimals, IE: 0.5 for a 2 second delay.
You can then combine a video and audio stream with something like this.
ffmpeg -i video.mp4 -i audio.mp3 -c:v copy -c:a aac -b:a 128k final.mp4
Of course choose your appropriate codecs. If you want an mp4 use libx264 for video and aac (built into ffmpeg and no longer "experimental") for audio.
Just remember that if you choose to use a method like this that ffmpeg output goes, by default, to stderr for when you try to read it. It can be redirected to stdout if you prefer.
The first thing that came to mind for me was imagemagick. I've used it with PHP for a lot of image manipulation and I know it supports reading a decent amount of video formats and according to that link it supports writing to some too.
yes, ffmpeg is the right solution for you. i just recently made something similar - a video site with animated thumbnails. i used ffmpeg to put together images in an aminated gif. however, the output can be whatever you need... unfortunately, in my searches into this topic i have not found any sample code that would combine all the points you are after, so i suppose you will have to try manually with ffmpeg... in my project i used php video toolkit http://sourceforge.net/projects/phpvideotoolkit/ in some parts to make it a bit easier...
You can use blend effect with ffmpeg:
ffmpeg -framerate 20 \
-loop 1 -t 0.5 -i 1.jpg \
-loop 1 -t 0.5 -i 2.jpg \
-loop 1 -t 0.5 -i 3.jpg \
-loop 1 -t 0.5 -i 4.jpg \
-c:v libx264 \
-filter_complex " \
[1:v][0:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b1v]; \
[2:v][1:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b2v]; \
[3:v][2:v]blend=all_expr='A*(if(gte(T,0.5),1,T/0.5))+B*(1-(if(gte(T,0.5),1,T/0.5)))'[b3v]; \
[0:v][b1v][1:v][b2v][2:v][b3v][3:v]concat=n=7:v=1:a=0,format=yuv420p[v]" -map "[v]" out.mp4
You should check bellow link for more effect of ffmpeg :D
