I have a mp4 file cutted from a H.264/AAC stream with Wowza Media Server.
After the cutting, the file was forced to mp4 format with the following command:
ffmpeg -i wowza_output_file -vcodec copy -acodec copy -f mp4 -y wowza_output_file_copy
From there I renamed it to test_f4v.mp4 and took ffprobe, to take a look at the file:

Now there is a problem. I need a file, which has the following meta data:
major_brand : mp42
compatible_brands: isom
Is there a way to remux the mp4 file to get the major_brand and compatible_brands to the described values with ffmpeg?
You can set arbitrary metadata using the -metadata flag for FFmpeg.
From the man page:
-metadata[:metadata_specifier] key=value (output,per-metadata)
Set a metadata key/value pair.
An optional metadata_specifier may be given to set metadata on
streams or chapters. See "-map_metadata" documentation for details.
This option overrides metadata set with "-map_metadata". It is also
possible to delete metadata by using an empty value.
For example, for setting the title in the output file:
ffmpeg -i in.avi -metadata title="my title" out.flv
To set the language of the first audio stream:
ffmpeg -i INPUT -metadata:s:a:1 language=eng OUTPUT
I don't know much about Wowza formatting, but since you're just copying the actual stream data and only changing the packaging, you could try the HandBrakeCLI for conversion to mp4. By default it sets major_brand to mp42 and compatible_brands to mp42isomavc1. Perhaps close enough?

I am not getting why this isn't working.. I have tried to get the video streams with [0:v]/[0:1]/[0:v:0] & the audio streams with [0:a]/[0:0]/[0:0:0].
nothing worked.
Explaining the inputs:
1.1st input stream is a video that can be of varying resolution on which the filter adds a padding on to make it 600:480.
2.2nd input is an overlay png which is already at 5:4 ratio.. just making it 600:480 before it gets overlaid in the filter.
3.3rd & 4th ones are also videos which I don't care if they get stretched.. n they are getting stretched to 600:480.
4.so finally there are 3 streams 1 overlaid video 2 stretched videos which needs to be concatenated.
here's the command :
ffmpeg

I've been searching everywhere to work out how to extract N images from a video using FFmpeg. All the answers involve playing with the rate setting (-r). However, I'm having some fundamental problems with the rate. According to the docs, the following should produce one frame per second.
ffmpeg -i input.mov -f image2 -r 1 preview-%d.jpeg
If input.mov is 7 seconds long, I would expect to get 7 images. However, I get 10. I also tried on a video 119 seconds long, but I got 122 images. I'm getting 3 more images than expected. What am I missing?
For example, with this ~3 second video I get six frames https://www.dropbox.com/s/8eke6q2gz1kgk1f/example.mov?dl=0
benblack$ ffmpeg -i example.mov -f image2 -r 1 preview-%d.jpeg

I don't know why -r doesn't produce what I expect. However, I managed to extract N frames by using -vf and -vsync:
ffmpeg -i example.mov -f image2 -vsync vfr -vf "select='not(mod(n,17)')" -vframes 10 preview-%d.jpeg
round(number of frames in video/number of frames wanted) = 168/10 = 17. The number of frames in the video can be found using ffprobe:
ffprobe -v error -select_streams v:0 -show_entries stream=nb_frames -i example.mov
The vframes setting is to limit the number of frames, because due to rounding we might sometimes generate one more frame.
Another popular way to extract images from videos is a frame per second.
If you want to extract a portion of images from a video use the -ss option to specify the starting timestamp, and the -t option to specify the encoding duration, eg from 52 seconds in for 1 minute and 5 seconds:
ffmpeg.exe -i simpsonsRockBottom.mp4 -ss 00:00:52 -t 00:01:05 -r 1/1 $filename%03d.jpg
The timestamps need to be in HH:MM:SS.xxx format or in seconds.
If you don't specify the -t option it will go to the end.
I am having an issue scaling videos recorded in portrait with the latest version of ffmpeg (2.1). This worked fine in a previous version, but I need the lastest version to fix a different issue.
I am trying to take any video passed and make it 852 wide by 480 high. It works fine when converting videos that are wider then tall, but when the video is taller then wide it corrupts the video. It actually adds a letter box to the top and bottom, rather then left and right. Also, the meta data shows it as the correct height & width, but its wrong when played in windows.
Here are the parameters I am using.
ffmpeg -i INPUT -s 852x480 -r 30 -aspect 1.775 -b:v 2000000 -vcodec mpeg4 -vf "scale=iw*min(852/iw\,480 /ih):ih*min(852/iw\,480 /ih),pad=852:480 :(852-iw)/2:(480 -ih)/2" -ac 2 -b:a 128k -ar 44100 -y OUTPUT

I have just installed ffmpeg and I am trying to encode all my uploaded videos to .mp4 file. Most of the users currently upload .mov and I want to convert every video to .mp4.
I am running the command as follows:
ffmpeg -i movie.mov -vcodec copy -acodec cop out.mp4
But all I am getting is the following errors

The command to just stream it to a new container (mp4) needed by some applications like Adobe Premiere Pro without encoding (fast) is:
ffmpeg -i input.mov -qscale 0 output.mp4
Alternative as mentioned in the comments, which re-encodes with best quaility (-qscale 0):
ffmpeg -i input.mov -q:v 0 output.mp4
I used to work on ffmpeg 2.2 until now and was detecting rotation angle of video uploaded from android / iPhone mobiles and rotate the resulting video so that it run perfectly on a correct angle.
But since I have updated the ffmpeg to version 2.8 I am getting this rotation problem. My queries are not rotating the videos as they were earlier.
Here'r the commands I was using:
To check rotation angle:
ffprobe -of json -show_streams {$input} | grep rotate
below is my final command to convert a video to mp4
"ffmpeg -i {$input} -strict -2 -vcodec libx264 -preset slow -vb 500k -maxrate 500k -bufsize 1000k -vf 'scale=-1:480 ".fix_video_orientation($input)."' -threads 0 -ab 64k -s {$resolution} -movflags faststart -metadata:s:v:0 rotate=0 {$output}";
"fix_video_orientation" function is given below. It detect the angle of rotation of the initial video and output optimal option for rotating the final video.
function fix_video_orientation($input){
$return= ", transpose=1 ";
$dd= exec("ffprobe -of json -show_streams {$input} | grep rotate");
if(!empty($dd)){
$dd=explode(":",$dd);
$rotate=str_replace(",","",str_replace('"',"",$dd[1]));
if($rotate=="90")return $return;
else if ($rotate=="180") return ", transpose=2,transpose=2 ";
else if($rotate == "270") return ", transpose=2 ";
}
Currently above script is supporting "flv","avi","mp4","mkv","mpg","wmv","asf","webm","mov","3gp","3gpp" extensions, also the script is supporting the resulting .mp4 file to play on all browsers and devices.
Now the ffprobe command is not returning rotation angle and so a portrait video if uploaded from iphone is showing as landscape on the website.
Output console of ffprobe command:

If latest version of ffmpeg (2.8) is used to auto rotate the video, can you please suggest me what option I need to add or remove from my final command.
Try asking this in superuser.com.
ffmpeg -i in.mp4 -c copy -metadata:s:v:0 rotate=0 -an out.mp4
