  • IP-Cam / CCTV-Cam Live Streaming on iPhone/iPad

    19 mai 2013, par user1744691

    I want to get stream of an ip-cam on my iPhone/iPad and want to display it on screen. By R&D i found that ffmpeg is the only way to achieve it but i found nothing on ffmpeg. Is there any other way to achieve it or a confirmed way to get compiled ffmpeg on mac please mention that. Material regarding how to use ffmepg or source code example will be highly appreciated.

    Is there nothing built-in framework to achieve it if not then please mention if there is any free framework/sdk to achieve this functionality.

    Thanks

  • Creating iPhone compatible video with ffmpeg from an image and MP3 file

    22 février 2020, par Gracie

    I have the following command that I have used to create an MP4 video file from an image and an MP3 file, it plays fine in a Chrome browser on desktop and on an Android phone - but it doesn’t work on an iPhone 10. Do I need some extra codec or setting to make this compatible for iPhone ? Should I be converting this into a MPEG file instead for wider compatibility ?

    ffmpeg -loop 1 -i 6f4aa5dfefc4dd32186f41315ad9d1e2-0.png -i "music.mp3" -c:v libx264 -tune stillimage -c:a aac -b:a 192k -pix_fmt yuv420p -shortest aa-image0.mp4

    Here are the ffprobe details for the input MP3 file used to create the MP4 video and also the ffprobe for that output file :

    Input #0, wav, from 'download0.mp3':
    
  Duration: 00:00:35.94, bitrate: 384 kb/s
    
    Stream #0:0: Audio: pcm_s16le ([1][0][0][0] / 0x0001), 24000 Hz, 1 channels, s16, 384 kb/s
    Input #0, mov,mp4,m4a,3gp,3g2,mj2, from 'aa-image0.mp4':
    
  Metadata:
    
    major_brand     : isom
    
    minor_version   : 512
    
    compatible_brands: isomiso2avc1mp41
    
    encoder         : Lavf58.22.100
    
  Duration: 00:00:38.76, start: 0.000000, bitrate: 505 kb/s
    
    Stream #0:0(und): Video: h264 (High) (avc1 / 0x31637661), yuv420p, 2664x1498 [SAR 1:1 DAR 1332:749], 367 kb/s, 25 fps, 25 tbr, 12800 tbn, 50 tbc (default)
    
    Metadata:
    
      handler_name    : VideoHandler
    
    Stream #0:1(und): Audio: aac (LC) (mp4a / 0x6134706D), 48000 Hz, mono, fltp, 138 kb/s (default)
    
    Metadata:
    
      handler_name    : SoundHandler

    The video seems to play on the iPhone, but the audio seems to start/stop constantly. Like it is a streaming issue (even though it is not). Maybe an MP3 encoding issue when I created the video ?

    Here are the test files I have used and created (any iPhone users will likely find the MP4 will not play the audio in the video properly) :

    https://ffmpeg-iphone-issue.netlify.com/tesla.jpg

    https://ffmpeg-iphone-issue.netlify.com/tesla.mp3

    https://ffmpeg-iphone-issue.netlify.com/tesla.mp4 (OUTPUT - Created from the 2 files above)

    In summary, two FFmpeg commands are required :

    1) Used to create iPhone/iOS compatible videos in FFmpeg from an image and MP3 (A slight modification to the command at the top of the page)

    and

    2) An FFmpeg command that could be used to fix or re-encode the video above so that it works on iPhone (A new command incorporating the parts so it works with iPhone and then to rebuild and fix the "broken" video. In a similar fashion to this video where he fixes a broken video https://www.youtube.com/watch?v=2FhmbKKh6mc [command in Youtube description])
