  • ffmpeg how can I get the overlay to apply to all images in the slideshow

    7 avril 2022, par user2785245

    This command applies the overlay image to only the first image of the slideshow series. I messed with labeling and can't figure out the correct labels to get the overlay to apply to all images in the video.

    


    /opt/bin/ffmpeg -y -framerate 1/3 -start_number 1 -i %01d.jpg -i $watermark.png -filter_complex "pad=500:500:(500-iw*min(500/iw\,500/ih))/2:(500-ih*min(500/iw\,500/ih))/2:color=white,overlay=250:420" out.mp4 2>&1


    


  • Audio clipping after amerge in FFmpeg

    23 avril 2021, par gooey_duck

    Hoping someone out there can help me with this audio issue I'm having using FFmpeg. I've written a bash script using FFmpeg that processes as source a broadcast quality ProRes (HQ) file with four mono tracks of audio. Source audio is LPCM 24-bit, 48kHz signed little endian, and I am exporting the same. Track 1 is full mix left, track 2 is full mix right, track 3 is music/FX left and track 4 is music/FX right. The script takes the source video and trims the video asset using in and out points from a sidecar XML. It also adds a custom slate at the head that uses a separate slate-only MOV file and is joined together via concat. Custom text is added to the slate via the drawtext filter and, finally, audio tracks 3 and 4 are removed and tracks 1 and 2 are merged together into a single stereo interleaved track using amerge.

    


    All of this, seemingly, works like a charm. The problem I'm noticing occurs when I run the resulting export through our in-house QC software. This software detects audio signal clipping at multiple points throughout the file created by FFmpeg. When I create this exact same file via Adobe Premiere or another transcode system, our QC does not detect any clipping. Our QC tools also do not detect any clipping in the source file. This leads me to believe that the clipping is being introduced either by FFmpeg or by my implementation of it. I've tried multiple additional filters within FFmpeg, including pan, amix, volume, etc., but nothing seems to help.

    


    Anyone have any ideas ? Pasting the relevant section of my script for reference :

    


    ffmpeg \
-ss "$hour":"$min":"$sec""$mil_fin" \
-t "$hour_minus":"$min_b":"$sec_b""$mil_fin_b" \
-i "$vid" \
-i "$elements_path"Slate_HD.mov \
-filter_complex \

:x=170:y=170+150:text='$transcode_date', \

-map '[o]' -map '[a]' \
-timecode 09:59:30:00 \
-c:v prores_ks -profile:v 3 \
-c:a pcm_s24le \
-threads 3 \
"$output_name".mov


    


    Per suggestion, simplified audio only command line was run as follows :

    


    ffmpeg -i test.mov -i Slate_HD.mov -filter_complex "[0:a:0] [0:a:1] amerge=inputs=2 [stereo];[1:a][stereo]concat=n=2:a=1:v=0" -c:a pcm_s24le test_output.mov


    


    ...and the log from that command line :

  • Broken Pipe Error [Errno 32] after saving more than ten PNG images using PIL

    6 septembre 2019, par Blinko

    I am using the ffmpeg pipeline to compress a series of png frames and output an mp4 video, while also saving each frame as a separate png image. The problem is that every time I run the script, I get a Broken Pipe error on the 11th image :

    Traceback (most recent call last):
    
  File "/anaconda3/envs/tensorflow/lib/python3.6/site-packages/PIL/ImageFile.py", line 487, in _save
    
    fh = fp.fileno()
    
AttributeError: '_idat' object has no attribute 'fileno'
    

    
During handling of the above exception, another exception occurred:

BrokenPipeError: [Errno 32] Broken pipe
    
</module>

    I am not too familiar with PIL or ffmpeg, so I am not sure whether it’s a problem with the pipe parameters that I am passing in or something to do with the code itself. No matter what the starting frame number is, the error always appears after 10 images are saved.

    Here is the array of pipe parameters I’m sending to the command prompt :

    command = ['ffmpeg',
    
       '-y',
    
       '-f', 'image2pipe',
    
       '-vcodec', 'png',
    
       '-r', '1',
    
       '-r', str(fps), # frames per second
    
       '-i', '-', # The input comes from a pipe
    
       '-an', # Tells FFMPEG not to expect any audio
    
       '-vcodec', 'mpeg4',
    
       '-b:v', '5000k',
    
       '../'+filename+"/"+filename+".mp4",
    
       '-hide_banner',
    
       '-loglevel', 'panic']

    This is the loop that generates and saves each image :

        for i in tqdm.tqdm(range(start_frame, end_frame)):
    
        frame = FrameRead(data, i)
    
        frame_image = np.zeros([ydim, xdim], dtype=np.uint8)
    
        frame_image[image_write_rows, image_write_cols] = frame.frame_data[sample_read_rows, sample_read_cols]
    

    
        all_frame_data.append(frame.frame_data)
    
        im = Image.fromarray(cm(frame_image, bytes=True))
    

    
        if timestamp == True:
    
            ts = str(datetime.datetime.fromtimestamp(frame.sonartimestamp/1000000, pytz.timezone('UTC')).strftime('%Y-%m-%d %H:%M:%S'))
    
            text = "%s\n%d" % (ts, i)
    
            draw = ImageDraw.Draw(im)
    
            draw.text(ts_pos,text,font=font, fill = 'white')
    

    
        im.save(directory+filename+'/frames/'+str(i)+'_'+str(frame.sonartimestamp)+'_'+filename+'.png'  , "PNG")
    
        im.save(pipe.stdin, 'PNG')
    
        j += 1

    I am running this on MacOS, Python 3.6. Help on the cause of the error and/or possible solutions will be greatly appreciated !
