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"

    'Video':'mp4',

    'Audio':'wav',

    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',

    if self.AUDIO:

        ffmpegAudio().start()

    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,

        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.

Error : mingw32/bin/ld.exe : cannot find -lbcrypt when compiling goav

18 avril 2018, par nevernew

I’m trying to compile goav on Windows and I’ve got quite far I’ve compiled the ffmpeg libraries in MSYS2 and linked the packages with :

set CGO_CFLAGS=-IC:\path\to\FFmpeg\

set PKG_CONFIG_PATH=%~dp0FFmpeg\libavformat;%~dp0FFmpeg\libavcodec;%~dp0FFmpeg\libavutil;%~dp0FFmpeg\libswresample;

which has worked !

However, I’m now getting the error could not determine kind of name for ...

exit code 2

How can I fix this so it can finish compiling ?

More Errors :

I commented out those lines in the source file to see if I could continue, but now I’m getting all these errors, Obviously I’m missing some step, does anyone have any insight ?

A Fix

I added the sub folders of FFmpeg to LDFLAGS and it’s not getting errors for those libraries anymore.

@set CGO_LDFLAGS=-L%~dp0FFmpeg\ -L%~dp0FFmpeg\libavformat -L%~dp0FFmpeg\libavcodec -L%~dp0FFmpeg\libavutil -L%~dp0FFmpeg\libswresample

I also found GNUWindows ports for zlib and bzip2, so their errors have disappeared.

But I’m still getting errors for -lbcrypt. anyone know where/how to go about getting this lib ?
