  • Heroku ffmpeg buildpack

    20 octobre 2015, par Manuel Quintanilla

    Putting together the video upload section in my rails app and am having some issues with video play on mobile phones. Im using

    paperclip-av-transcoder, s3 and  Heroku

    On my laptop I can visit the page and see the video thumbnails and play the videos only because I have previously installed ffmpeg to my machine.

    Remotely on Heroku I’ve set the appropriate buildpacks for ffmpeg and have run push heroku master to install the buildpacks - Now when I visit the page on my mobile iPhone I don’t get a thumbnail but when I play the video it plays - on the other hand when I visit the page on my Android phone I don’t get a thumbnail and the video dose not play but I can upload mp4s on Android.

    Check out my set up here : Heroku ffmpeg buildpacks for video uploads

    It seems I don’t have the proper buildpack setup or some other heroku setting with ffmpeg.

    Any suggestions ? Thanks in advance !

  • FFmpeg HLS Live Stream Stuck with iOS 11

    1er novembre 2017, par Lamorun

    I’ve exp with FFmpeg but i recent problem with iOS 11 (Recent release for Apple)

    I used FFmpeg for stream HLS Live Stream for only iPhone and iPad in closed app for online courses. My problem is the next :

    I used this code for HLS Live Stream :

    ffmpeg -i "Input" -preset fast -c:v libx264 -c:a aac -ac 1 -strict -2 -crf 18 -profile:v baseline -maxrate 1000k -bufsize 1835k -pix_fmt yuv420p -b:a 64k -flags -global_header -hls_time 20 -hls_list_size 6 -hls_wrap 10 -start_number 1 /m3u8/test.m3u8

    This work perfect in iOS 8, 9 and 10 devices. But with new version iOS 11, video is stuck after about 30 to 40 seconds, as seen in the image :

    ios11stuck

    I have searched for hours and hours. I have done many tests, but I can not get it out, since it works perfectly with iOS 8,9 and 10 (test in somes devices, even working perfectly on a device with iOS 10, update to iOS 11, and stop working immediately, downgrade to iOS 10 and work again)

    I hope someone can help me out, thank you and greetings to all

  • Usage FFmpeg command to capture video from Apple device camera and to get 3 outputs with different resolutions (UHD, FHD, HD)

    12 décembre 2019, par Levon Gharibyan

    I use mobile-FFmpeg to execute FFmpeg commands (https://github.com/tanersener/mobile-ffmpeg).

    I am using AVFoundation, and trying to get 3 output files (3840x2160, 1920x1080 and 1280x720) from device camera.
    Here is the command :

    -f videotoolbox -f avfoundation -video_size 3840x2160 -r 30 -pixel_format nv12 -i "0:0"  -c:v h264_videotoolbox -b:v 8M -maxrate 8M -s 3840x2160 output1/path -c:v h264_videotoolbox -b:v 8M -maxrate 8M -s 1920x1080 output2/path -c:v h264_videotoolbox -b:v 8M -maxrate 8M -s 1280x720 output3/path

    But the encoding process is very slow (0.3x-0.4x speed) with that command and as a result, I can’t record realtime 30fps outputs. What am I doing wrong ? All my tests were done on the iPhone 7.
