  • "ffmpeg has text relocations" error in Android

    5 janvier 2015, par djzmo

    I’m building an Android video-sending application. I need the video to be compressed before being uploaded. In this case, I chose to use this Android wrapper of FFmpeg : https://github.com/hiteshsondhi88/ffmpeg-android-java

    FFmpeg error: WARNING: linker: /data/data/com.mycompany.myapplication/files/ffmpeg has text relocations. This is wasting memory and prevents security hardening. Please fix.

    Everything seemed fine when I compress small files (below 20 seconds), but when I tried to compress larger files, I seldom get the above error in the middle of the compression process, and the process was also terminated immediately. I need the application to be able to compress one minute video to about 20-35 MB.

    Here is the FFmpeg command I used :

    ffmpeg -y -i -codec:v libx264 -profile:v baseline -level 3.0 -b:v 2500k -minrate 2500k -maxrate 2500k -bufsize 1835k -pix_fmt yuv420p -preset ultrafast -crf 28 -codec:a copy

    Any idea on what went wrong ?
    Any kind of help would be very appreciated.

  • FFMPEG not working from Python subprocess.Popen but works from command line

    21 novembre 2017, par Stuart Clarke

    I’m trying to run a FFMPEG script from within python 3.5.2. the FFMPEG command runs fine from the command line but fails within the python script.

    The function I use to execute the FFMPEG command is

    def ffmpeg(args):
    
    err = None
    
    command = [
    
        ffmpegcmd, '-y',
    
        '-loglevel', loglevel
    
    ] + args
    
    print("\n\n\n")
    
    print(command)
    
    print("\n\n\n")
    
    print(" ".join(command))
    
    ffmpeg = subprocess.Popen(command, stderr=subprocess.PIPE ,stdout=subprocess.PIPE, universal_newlines=True)
    
    while err == None:
    
        out, err = ffmpeg.communicate()
    
        time.sleep(1)
    
    if err and loglevel=='fatal':
    
        print(" ".join(command))
    
        raise Exception(err)
    
    print(err)

    The value for args is :

    ['-i', '/var/www/temp/film.mp4', '-vf', 'scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black', '/var/www/temp/videoHD.mp4']

    such that the resultant command being passed to subprocess.Popen is :

    ['ffmpeg', '-y', '-loglevel', 'verbose', '-i', '/var/www/temp/film.mp4', '-vf', 'scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black', '/var/www/temp/videoHD.mp4']

    The value of loglevel is verbose only for troubleshooting but is intended to run as fatal. There are also some print commands only in place for troubleshooting.

    The reason for wanting to increase the resolution is so that it can be combined later with higher resolution videos.

    The result when running from within python is :

    This results in a file with no content.

    When I run the command from the command line I need to add single quotes around the -vf video filters scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black so the whole command becomes :

    ffmpeg -y -loglevel verbose -i /var/www/temp/film.mp4 -vf 'scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black' /var/www/temp/videoHD.mp4

    Running this command gives the required result.

    and the resulting video is fine.

    Any ideas ?

    Cheers,

    Edit

    It was suggested that I use a new function to do much the same thing. So I added the following function and used it for the command that I’m having trouble with :

    def ffmpegPro(args):
    
    err = None
    
    for i, arg in enumerate(args):
    
        if(" " in arg or "(" in arg or "[" in arg):
    
            args[i] = "\"" + arg + "\""
    
    command = [
    
        ffmpegcmd, '-y',
    
        '-loglevel', loglevel
    
    ] + args
    
    commandStr = " ".join(command)
    
    print("\n\n\n")
    
    print(command)
    
    print("\n\n\n")
    
    print(commandStr)
    
    ffmpeg = subprocess.Popen(commandStr, stderr=subprocess.PIPE, stdout=subprocess.PIPE, universal_newlines=True, shell=True)
    
    while err == None:
    
        out, err = ffmpeg.communicate()
    
        time.sleep(1)
    
    if ffmpeg.returncode == 0 and all([os.path.exists(f) for f in (videoStorage['data_small'], videoStorage['data_big'])]):
    
        print("Job done.")
    
    else:
    
        print("ERROR")
    
        print(err)

    The resulting command can now be used in python or at the command line without needing to be changed at all. The command is :

    ffmpeg -y -loglevel verbose -i /var/www/temp/film.mp4 -vf "scale=1920:1080:force_original_aspect_ratio=decrease,pad=1920:1080:x=(1920-iw)/2:y=(1080-ih)/2:color=black" /var/www/temp/videoHD.mp4

    The result when executed in python is

Killed

    Note the Killed at the end. Is this significant and why is it only happening when executed in the script ?

    Here is the output from the command line which results in a successful video file.

    Any more ideas why this is being handled differently in python as opposed to the command line ?

    I’m believe this is a version issue and that is why the below answer did not work for me, things were fine before I upgraded but since then a lot of things have been playing up. I upgraded both ffmpeg and python versions and don’t really want to go back if it can be avoided.

    Thanks,

    Stu

  • FFMpeg video recorder - Android

    30 avril 2014, par Ganesh

    I’ve used ffmpeg video recorder for android.

    it has used videocodec as MPEG4.

    private int videoCodec = avcodec.AV_CODEC_ID_MPEG4;

    video is showing android and iphone device. but video not playing on browser only audio playing on browser.

    I’ve checked HTML5 video requires MP4 videos with H264 video codec and AAC audio codec

    Chrome doesn’t display html5 video but plays audio

    I’ve changed videocodec as below

    private int videoCodec = avcodec.AV_CODEC_ID_H264;

    My question is,

    when i use Mpeg4, video croping time is less.
    But when i use H264 , video croping time takes more.

    How to reduce the video croping time when use H264 or anyother videocode support to browser and minimum processing time for video croping.?
