  • Play video using mse (media source extension) in google chrome

    23 août 2019, par liyuqihxc

    I’m working on a project that convert rtsp stream (ffmpeg) and play it on the web page (signalr + mse).

    So far it works pretty much as I expected on the latest version of edge and firefox, but not chrome.

    here’s the code

    public class WebmMediaStreamContext
    
{
    
    private Process _ffProcess;
    
    private readonly string _cmd;
    
    private byte[] _initSegment;

    private const string _CmdTemplate = "-i {0} -c:v libvpx -tile-columns 4 -frame-parallel 1 -keyint_min 90 -g 90 -f webm -dash 1 pipe:";
    

    
    public static readonly byte[] ClusterStart = { 0x1F, 0x43, 0xB6, 0x75, 0x01, 0x00, 0x00, 0x00 };
    

    
    public event EventHandler<clusterreadyeventargs> ClusterReadyEvent;
    

    
    public WebmMediaStreamContext(string rtspFeed)
    
    {
    
        _cmd = string.Format(_CmdTemplate, rtspFeed);

    I use ffmpeg to convert the rtsp stream to vp8 WEBM byte stream and parse it to "Init Segment" (ebml head、info、tracks...) and "Media Segment" (cluster)， then send it to browser via signalR

    $(function () {
    

    
    var mediaSource = new MediaSource();
    
    var mimeCodec = 'video/webm; codecs="vp8"';
    

    
    var video = document.getElementById('video');
    

    
    mediaSource.addEventListener('sourceopen', callback, false);
    
    function callback(e) {
    
        var sourceBuffer = mediaSource.addSourceBuffer(mimeCodec);
    
        var queue = [];
    

    
        sourceBuffer.addEventListener('updateend', function () {
    
            if (queue.length === 0) {
    
                return;
    
            }
    

    
            var base64 = queue[0];
    
            if (base64.length === 0) {
    
                mediaSource.endOfStream();
    
                queue.shift();
    
                return;
    
            } else {
    
                var buffer = new Uint8Array(atob(base64).split("").map(function (c) {
    
                    return c.charCodeAt(0);
    
                }));
    
                sourceBuffer.appendBuffer(buffer);
    
                queue.shift();
    
            }
    
        }, false);
    

    
        var connection = new signalR.HubConnectionBuilder()
    
            .withUrl("/signalr-video")
    
            .configureLogging(signalR.LogLevel.Information)
    
            .build();
    
        connection.start().then(function () {
    
            connection.stream("InitVideoReceive")
    
                .subscribe({
    
                    next: function(item) {

                            var buffer = new Uint8Array(atob(item).split("").map(function (c) {

                            }));
    
                            sourceBuffer.appendBuffer(buffer);
    
                            console.log(blockindex++ + " : " + buffer.byteLength);
    
                        } else {
    
                            queue.push(item);
    
                        }

                    complete: function () {

                });
    
        });
    
    }
    
    video.src = window.URL.createObjectURL(mediaSource);
    
})

    chrome just play the video for 3 5 seconds and then stop for buffering, even though there are plenty of cluster transfered and inserted into SourceBuffer.

  • Not all portions of video play well after concatenation

    24 septembre 2018, par srgbnd

    Node.JS 8.11.4, fluent-ffmpeg 2.1.2

    I need to concatenate random portions of the same length of different videos in one video file. The concatenation proceeds without errors. But when I play the final concatenated file I see some portions playing well with sound, others have video "frozen" but sounds playing.

    What’s the problem ? I want all portions playing well in the final concatenated file.

    Concatenation config :

    trex@cave:/media/trex/safe1/Development/app$ head concat_config.txt
    
file /media/trex/safe1/Development/app/videos/test/417912400.mp4
    
inpoint 145
    
outpoint 155

inpoint 144
    
outpoint 154
    
    ...

    In total, I have 16 portions of 2 videos. Duration of a portion is 10 sec. In the future the number of video files and portions will be much bigger.

    trex@cave:/media/trex/safe1/Development/app$ ls -lh videos/test/

  • Ruby on Rails - Paperclip - ffmpeg - throws error when adding style to "has_attached_file"

    4 octobre 2018, par TamerB

    I’m working on image and video upload in a rails app using paperclip and ffmpeg.

    The following code in models/image.rb is working fine :

    has_attached_file :image,
    
processors: [:ffmpeg]
    
validates_attachment_content_type :image, content_type: /.*/

    But, when I add styling to the code as follows, it throws an error on (page loading) :

    has_attached_file :image, styles: lambda {|a| if a.instance.is_image? then {original: {}, medium: "300x300>"} end},
    
processors: [:ffmpeg]
    
validates_attachment_content_type :image, content_type: /.*/
    

    
def is_image?
    
  return false unless @attachment_image.content_type
    
  ['image/jpeg', 'image/pjpeg', 'image/gif', 'image/png', 'image/x-png', 'image/jpg'].include?(@attachment_image.content_type)
    
end

    The error is as follows :

    F, [2018-10-04T15:04:47.381706 #9836] FATAL -- : [643e7428-d41e-4000-9a48-566d85e7b109]

</top>

    How can I solve this ?

    Update

    This error is displayed only when trying to upload a video or or trying to load a page containing a video.

    The code in pp/admin/resorts.rb mentioned in the error message is the following (I’m using activeadmin gem) :

    if im.itype == 'video-slider' then
    
    video_tag im.image, class: 'my_image_size' # line 46
    
else
    
    image_tag im.image, class: 'my_image_size'
    
end

    When trying to upload an image, the error changed to be as follows () :

    Input #0, image2, from '/tmp/dcdc7c452102ec2b9255973f59b40ee320181004-23173-fx7vzi.jpg':
