    I'm trying to upload file to s3 using ffmpeg, and its creating a 0B file, what could be the reason behind this?

  • python ffmpeg moov atom not found Invalid data when processing input

    11 mai 2018, par Isocrates

    I have a progress that records the screen, and audio from a microphone, and then combines the video and audio recording (.mp4 and .wav) into one mkv file.

    I am using python 3.6 and ffmpeg to achieve this aim. For short videos (<20 sec.) it works, but for longer recordings it presents the following error message:

    [mov,mp4,m4a,3gp,3g2,mj2 @ 0x55abb3a52540] moov atom not found
tmp/tmp_0.mp4: Invalid data found when processing input

    The python file (ffmpeg.py) is as follows. The class, AV_COMPILE, is not yet complete, held up by the aforementioned error, and therefore still uses the initial test files as defaults. But otherwise it ought to work:

    import os, time, glob

TMP_DIR = "tmp"
DISPLAY = os.environ['DISPLAY']
EXT = {
    'Video':'mp4',
    'Audio':'wav',
    'AV':'mkv',
}

class ffmpegVideo:

    FFMPEG_BIN = "ffmpeg"
    AUDIO = False

    def __init__(self, fps = 30, audio = True):
    global TMP_DIR, DISPLAY, EXT

    self.fps = fps

    if audio:
        self.AUDIO = True

    self.video_filename = self.unique_filename()

    self.command = [ self.FFMPEG_BIN,
        '-video_size', '1920x1080',
        '-framerate', str(fps),
        '-f', 'x11grab',
        '-i', DISPLAY,
        '-vcodec', 'libx264',
        '-qp', '0',
        '-preset', 'ultrafast',
        '-y', TMP_DIR + '/' + self.video_filename
    ]

def start(self):
    import threading as th

    thread = th.Thread(target=self.record)
    thread.start()

def record(self):
    import subprocess as sp

    self.pipe = sp.Popen(self.command, stderr=sp.PIPE)

    if self.AUDIO:
        ffmpegAudio().start()

def stop(self):
    self.pipe.terminate()

def unique_filename(self):
    global TMP_DIR, EXT

    i = 0

    while os.path.exists((TMP_DIR + '/' + 'tmp_%s.%s') % (i, EXT['Video'])):
        i += 1

    return ('tmp_%s.%s') % (i, EXT['Video'])

class ffmpegAudio:

    FFMPEG_BIN = "ffmpeg"

    def __init__(self):

        self.audio_filename = self.unique_filename()

        self.command = [ self.FFMPEG_BIN,
            '-f', 'pulse',
            '-ac', '2',
            '-ar', '48000',
            '-i', 'default',
           '-acodec', 'pcm_mulaw',
           '-y', TMP_DIR + '/' + self.audio_filename
        ]

    def start(self):
        import threading as th

        au_thread = th.Thread(target=self.record)
        au_thread.start()

    def record(self):
         import subprocess as sp

        self.pipe = sp.Popen(self.command, stderr=sp.PIPE)

    def stop(self):
        self.pipe.terminate()

    def unique_filename(self):
        global TMP_DIR, EXT

        i = 0

        while os.path.exists((TMP_DIR + '/' + 'tmp_%s.%s') % (i, EXT['Audio'])):
        i += 1

        return ('tmp_%s.%s') % (i, EXT['Audio'])

class AV_COMPILE:

    def __init__(self, au_in = TMP_DIR + '/' + 'out1.wav', vd_in = 
TMP_DIR + '/' + 'test4.mp4', out = TMP_DIR + '/' + 'av.mkv'):
        import subprocess as sp

        au_in = min(glob.iglob(TMP_DIR + '/*.wav'), key=os.path.getctime)
        vd_in = min(glob.iglob(TMP_DIR + '/*.mp4'), key=os.path.getctime)

        self.command = ('ffmpeg -i %s  -r 30 -i %s -shortest -c:a aac -c:v copy %s') % (au_in, vd_in, out)
        sp.call(self.command, shell=True)

    I would be grateful for any assistance you could provide in understanding why this happens and how to solve the error. Also, I am happy to receive any other tips on how to improve this code, or any other problems anyone might notice.

    EDIT: I now believe that the reason for this error in longer videos, and occasionally shorter, is that the program is proceeding to attempt to compile the av output whether or not it has finished compiling the original video file. I tested a time.sleep(10) function to delay AV_COMPILE, and this seems to work.

    However, as video files get larger, obviously the delay needs to be adjusted. So I should like to know how I can separately check the integrity of the video file and determine that it is safe to proceed to the next step.

  • is there any functional build of ffmpeg to android

    11 mai 2018, par Rafael Lima

    I've searching the last 3 days for a usable API for android access ffmpeg. Since FFMpeg group doesn't release an official lib for android I found several paralel projects trying to build it.

    So it brings me to my nightmare that is called compile.

    i've followed all these tutorials: https://trac.ffmpeg.org/wiki/CompilationGuide/Android

    And others found in different places. but none of them build

    NONE OF THEM IS LESS THAN 3 YEARS OLD

    Sorry for the caps, but it is frustrating... no ffmpeg build projects I found deal with nkd above 14 and google doesn't keep in archive nkds older than that, so even if i agree with get all outdated libraries source i cant reproduce de compiler i cant download the same ndk...

    The only api i manage to download with a functional build of ffmpeg probably was compiled without some codecs, because on my tests i can only handle few types of videos

    ===============================================================

    The question is, does anyone know an actual, stable, project for building ffmpeg to android?

    I'm even willing to pay in order to get a working version of it
