Running ffmpeg command on Android results in "Unable to find a suitable output format for ' -map 0:v:0 -map 1:a:0'"
5 juin 2017, par Akash DubeyI am using this command for replacing audio of video and genrate new video having new audio. Here file1 is my video.mp4, file2 is my audio.mp3 and output would be the output.mp4 :
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};Below is My code :
private void changeAudioofVideo(String selectedUri, String videoPath) {
String[] complexCommand;
File f = new File("/storage/emulated/0");
if (!f.getParentFile().exists())
f.getParentFile().mkdirs();
if (!f.exists())
try {
f.createNewFile();
} catch (IOException e) {
e.printStackTrace();
}
file1 = new File(videoPath);
if (file1.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
file2 = new File(selectedUri);
if (file2.exists()) {
Log.d("yes", "File 1 exists");
} else {
Log.d("no", "File 1 not exists");
}
String rootPath = f.getPath();
complexCommand = new String[]{"-y", "-i", file1.toString(), "-i", file2.toString(), "-c", "copy", " -map 0:v:0 -map 1:a:0", rootPath + "/output.mp4"};
FFmpeg ffmpeg = FFmpeg.getInstance(this);
try {
//Load the binary
ffmpeg.loadBinary(new LoadBinaryResponseHandler() {
@Override
public void onStart() {

} catch (FFmpegNotSupportedException e) {

}
try {

ffmpeg.execute(complexCommand, new FFmpegExecuteResponseHandler() {

FFmpeg fontcolor_expr to dynamically change fontcolor over time
26 juin 2017, par MatthewI’m using Fluent-FFmpeg with Node.JS to create videos with text overlaid on them and I’m wanting to change the color of the text as the video progresses.
My filters follow this pattern :
drawtext=enable='between(t,18.93,20.28)':fontfile=fonts/cousine-bold.ttf:fontsize=144:fontcolor_expr=%{expr\\\: if(between(t\\, 0\\, 20)\\, 888888\\, 111111)}:x=82:y=288:text='PROGRAMMING'And it prints out this stuff :
