  • NGINX RTMP convert flv to hls ?

    3 mai 2016, par MandelDuck

    I have a server that takes an rtmp stream and saves it as flv.

    Web users can view the flv video in their browser, however iPhone users can’t as it is flash

    Is there away to convert the saved flv files on the fly to hls for the iPhone viewers ?

    here is my config, Webusers access the vod application

    rtmp {
    
     server {
    
             listen 1935;
    
             chunk_size 4096;
    

    
             application live {
    
                     live on;
    
                     record all;
    
                     record_path /videos/av;
    
                     idle_streams off;
    
             }
    
             application audio {
    
                     live on;
    
                     record audio;
    
                     record_path /videos/audio;
    
                     idle_streams off;

  • Reading geolocation data from a video file using FFMpeg/Xuggler

    23 décembre 2015, par agent154

    Using the MediaInfo application, I am able to see that a file taken with an iPhone 5 contains geolocation metadata, tagged both with ©xyz and com.apple.quicktime.location.ISO6709. I am not able to find any way to get this data using xuggler, however.

    Format                                   : MPEG-4
    
Format profile                           : QuickTime
    
Codec ID                                 : qt   0000.00 (qt  )
    
File size                                : 7.50 MiB
    
Duration                                 : 3s 537ms
    
Overall bit rate                         : 17.8 Mbps
    
Recorded date                            : 2015-12-17T14:32:23-0330
    
Encoded date                             : UTC 2015-12-17 18:02:23
    
Tagged date                              : UTC 2015-12-17 18:02:27
    
Writing application                      : 8.4.1
    
Writing library                          : Apple QuickTime
    
Model                                    : iPhone 5
    
©xyz                                     : +47.5184-052.8046+133.390/
    
Make                                     : Apple
    
com.apple.quicktime.make                 : Apple
    
com.apple.quicktime.creationdate         : 2015-12-17T14:32:23-0330
    
com.apple.quicktime.location.ISO6709     : +47.5184-052.8046+133.390/
    
com.apple.quicktime.software             : 8.4.1
    
com.apple.quicktime.model                : iPhone 5

    As an aside, there seems to be a lot of metadata on this file that I can’t immediately find while debugging via xuggler.

    The question at Reading Geolocation from Quicktime Movies with Java (Xuggler) ? is asking the exact same question, but has no answers or comments at all, and is over 4 years old.

    Is anybody aware of a way to be able to get this data using xuggler as it is, or how I can modify the source and re-compile to make it work ? I am required to get this data for a work project. Thanks.

  • ffmpeg converted x264 video shows sharply reduced color saturation

    3 novembre 2015, par xaphod

    I’m an ffmpeg noob. I did spend 30 mins googling stackoverflow though, and didn’t find an answer.

    My designer made me some videos, of animated drawings. They’re great, but huge. So I tried passing them through ffmpeg. They get 10x smaller and don’t look pixelated — great ! — but the color is greatly reduced. What’s bright red/pink in the original becomes washed out ashey-grey-red in the output, when I view it on my macbook, or in the app it’s going into (iOS — ie. on an iPhone 5S you can see the missing color). How can I get the color to stay the same(ish) ?

    ffmpeg -i original.mp4

    shows me this :

    ... so far I tried ...

    ffmpeg -i original.mp4 -vf format=yuvj420p -color_range 2 -vcodec libx264 out.mp4

    ... and many others, but no luck.

    Original.mp4 is here : http://fuzzymunchkin.com/tmp/original.mp4

    EDIT : posting the output of a (no-parameters) conversion, as requested.
