• FFPMEG Adding Watermark Is Producing An Error

  19 janvier 2021, par Glen Elkins

  I have an mp4 video and i'm using FFMPEG on command line in php to add an image to the bottom right corner as watermark :

  


  shell_exec('ffmpeg -y -i ' . $videoPath . ' -i ' . $path . ' -filter_complex "overlay=x=(main_w-' . $logoWidth . ')-10:y=(main_h-' . $logoHeight . ')-10" ' . $videoPath);


  


  It overwrites the original video with the new one. The logo is added to the video but the video ends up being 0 seconds long (originally 1 minute) and i see this error when the command is run :

  


  


  [h264 @ 0x134e540] Invalid NAL unit size (20328 > 14044). [h264 @
0x134e540] Error splitting the input into NAL units. Error while
decoding stream #0:0 : Invalid data found when processing input

  


  


  I have absolutely no idea what this means. Here is the entire output of the command :

• How to convert mp4 to mp3 in Android Java ?

  16 août 2023, par Akshit

  I have the mp4 link of a video but don't have a link for the mp3 version of that mp4 video. So is there any way that I can convert that mp4 video to mp3 in Android ? I saw some resources but nothing works for me. I have two ways in which I believe this can be achieved

  


  

  1. Convert the mp4 link to mp3 directly. (Not Sure if this is achievable)

  


  2. Download the mp4 on the device with the help of a link and then use some code to convert that mp4 to mp3.

  


  


  I also tried some solutions which are available online

  


  https://github.com/tanersener/mobile-ffmpeg

  


  I tried the above library to achieve the final goal. But got : Async command execution failed with returnCode=1.

  


  This error in the code I am using is :

  


  private class Mp4ToMp3ConverterTask extends AsyncTask {
    @Override
    protected String doInBackground(String... params) {
        String mp4FilePath = params[0];
        String mp3OutputPath = Environment.getExternalStorageDirectory().getAbsolutePath() + "/output.mp3";

        String[] ffmpegCommand = {"-i", mp4FilePath, "-vn", "-ar", "44100", "-ac", "2", "-b:a", "192k", mp3OutputPath};


        Config.enableStatisticsCallback(new StatisticsCallback() {
            public void apply(Statistics newStatistics) {
                Log.d("Dekh", String.format("frame: %d, time: %d", newStatistics.getVideoFrameNumber(), newStatistics.getTime()));
            }
        });

        long executionIdd = FFmpeg.executeAsync(ffmpegCommand, new ExecuteCallback() {
            @Override
            public void apply(final long executionId, final int returnCode) {
                if (returnCode == RETURN_CODE_SUCCESS) {
                    Log.i("Dekh", "Async command execution completed successfully.");
                } else if (returnCode == RETURN_CODE_CANCEL) {
                    Log.i("Dekh", "Async command execution cancelled by user.");
                } else {
                    Log.i("Dekh", String.format("Async command execution failed with returnCode=%d.", returnCode));
                }
            }
        });

        FFmpeg.cancel(executionIdd);

        return mp3OutputPath;
    }
}


  


  Solution number 2 which I used is :

  


  https://androidprogrammatically425516919.wordpress.com/2020/04/21/how-to-convert-video-to-audio-in-android-programmatically/

  


  But I got an error here also : Failed to instantiate extractor.
  
And another error is : java.io.FileNotFoundException: open failed: EISDIR (Is a directory)

  


  I tried the online available solution to solve these errors but nothing worked. Such as granting write permission. Providing a valid location to save the output.

  


  But nothing works so far. Please help me on this. Thank you.

  


• how to encode 25fps

  20 novembre 2020, par Vadik Jony

  i am not a programmer, but a part of my job is recoding. The person befor me left a script that recodes videos.
THE CURRENT PROBLEM : i need to add to the script the line to recode any video to 25 fps. I tried adding -filter:v fps=fps=25 to the script and it works BUT it ignores all other recoding settings. So i would be very happy if someone could help. Sorry for my trivial language, as i said - i am not a programmer :(
HERE IS THE SCRIPT :

  


  import os, subprocess


DIR = r"\\server-01\E\_NEW CONTENT\_Current Time\Actual Programs" 


EXP = r"\\server-01\D\_RENDERED CONTENT\Current Time" 
print ( "=-===-=-=-="  )

ALLDIR =  os.listdir(DIR)
#ext = ".mp4"
#ext = ".mov"
ext = ".mpg"

FL0 = [x for x in ALLDIR if x.endswith("mpg") or x.endswith("mp4") or x.endswith("mxf") or x.endswith("mov") ]


CL = len(FL0)
print ( "Amount of files: ", CL )

for i in range(0, CL):
#for i in range(0, 1):
#for i in range(12, CL):
    vfs = []

cur_name = FL0[i]
print ("Input file path: ", cur_name)

new_name = os.path.splitext(cur_name)[0] + ".mp4"
PATH = DIR + os.sep + cur_name

EXPATH = EXP + os.sep + new_name

if Deint:
    #yadif = " -vf \"yadif=0:0:0\" "
    vfs.append("yadif=0:0:0")
    #vfs.append("drawbox=x=0:y=0:w=720:h=2:color=black:t=max")
    #yadif = " -vf \"yadif=0:0:0,drawbox=x=0:y=0:w=720:h=4:color=black:t=max\" "
else : yadif = ""
if interlaced_tff:
    vfs.append("fieldorder=tff" )

else: vfcmd = ""
print (vfcmd)
cmd = "ffmpeg -hide_banner -i \"" + PATH + "\" " + vfcmd 

if recode:
    
    cmd = cmd + ' -aspect "16:9" -profile:v main -c:v libx264 -pix_fmt yuv420p -filter:v fps=fps=25  '

cmd = cmd + "\"" + EXPATH + "\""

print ( cmd )
cmdlist.append(cmd)
print ( "=-===-=-=-=" )
subprocess.call(cmd)


  


  and here is the text i am getting from FFMPEG :
