  • Why this shell command doesn't work ? ('command' works but 'command|cat' doesn't work)

    16 octobre 2018, par yabee

    Problem

    The following code outputs like...

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1
    
key_frame=1
    
pkt_pts=0
    
pkt_pts_time=0:00:00.000000
    
--
    
key_frame=1
    
pkt_pts=41041
    
pkt_pts_time=0:00:01.710042
    
--
    
key_frame=1
    
pkt_pts=64064
    
pkt_pts_time=0:00:02.669333
    
--
    
key_frame=1
    
pkt_pts=87087
    
pkt_pts_time=0:00:03.628625
    
--
    
...

    But the folowing one outputs nothing.

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2 key_frame=1|cat

    And...

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1
    
key_frame=1
    
key_frame=1
    
key_frame=1
    
key_frame=1
    
$ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep key_frame=1|cat
    
# Nothing outputted.

    Why ?

    Expected result

    What actually I want to do is

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time
    
pkt_pts_time=0:00:00.000000
    
pkt_pts_time=0:00:01.710042
    
pkt_pts_time=0:00:02.669333
    
pkt_pts_time=0:00:03.628625
    
...

    But its result is

    $ ffprobe -show_frames -select_streams v test.mp4 2>/dev/null|grep -A 2key_frame=1|grep time
    
# Nothing outputted.

    Grep works correctory exept it’s after ffprobe.

    $ seq 30|grep 1|grep 2

You have to specify one input file.
    
Use -h to get full help or, even better, run 'man ffprobe'.

    What is problem ?

    Does grep or ffprobe change its behavior by existence of pipe in this case ?
    Thanks.

  • Video decoding by the online player [closed]

    10 janvier 2024, par rahkarenovin

    I encoded my videos with 32-bit ffmpeg.

    


    I want the video player to decode and then display the video when the user buys it.

    


    My problem :
I don't know how to decode the video so that the player can display it

    


    My player code :

    


    <div class="grid">&#xA;    <main>&#xA;        <div>&#xA;            &#xA;            &#xA;        </div>&#xA;    </main>&#xA;</div>&#xA;&#xA;<code class="echappe-js">&lt;script&amp;#xA;    type=&quot;text/javascript&quot;&amp;#xA;    src=&quot;https://cdn.polyfill.io/v2/polyfill.min.js?features=es6,Array.prototype.includes,CustomEvent,Object.entries,Object.values,Math.trunc&quot;&amp;#xA;    crossorigin=&quot;anonymous&quot;&amp;#xA;&gt;&lt;/script&gt;&#xA;&#xA;&lt;script type=&quot;text/javascript&quot; src=&quot;https://cdn.plyr.io/3.5.2/plyr.js&quot;&gt;&lt;/script&gt;&#xA;&#xA;&lt;script type=&quot;text/javascript&quot; src=&quot;https://cdn.jsdelivr.net/npm/hls.js@latest&quot;&gt;&lt;/script&gt;&#xA;&#xA;&lt;script&gt;&amp;#xA;    const source = &amp;#x27;https://bitdash-a.akamaihd.net/content/sintel/hls/playlist.m3u8&amp;#x27;;&amp;#xA;    const player = new Plyr(&amp;#x27;#player&amp;#x27;);&amp;#xA;    var video = document.getElementById(&amp;#x27;player&amp;#x27;);&amp;#xA;    if(Hls.isSupported()) {&amp;#xA;       var hls = new Hls();&amp;#xA;       hls.loadSource(source);&amp;#xA;       hls.attachMedia(video);&amp;#xA;       hls.on(Hls.Events.MANIFEST_PARSED,function() {&amp;#xA;           video.play();&amp;#xA;        });&amp;#xA;    }else if (video.canPlayType(&amp;#x27;application/vnd.apple.mpegurl&amp;#x27;)) {&amp;#xA;       video.src = source;&amp;#xA;       video.addEventListener(&amp;#x27;loadedmetadata&amp;#x27;,function() {&amp;#xA;           video.play();&amp;#xA;        });&amp;#xA;    }&amp;#xA;&lt;/script&gt;&#xA;
