• HTML5 Video tag switcher for multiple resolutions

  20 avril 2016, par somecalmetim

  I have a Rails 4 app setup as a video upload/sharing site. I am using paperclip to upload videos and ffmpeg for processing 2 sizes of video into Mp4, ogg and webm.

  I want to show the smaller 240p video to mobile devices. I can do that now with media queries or Bootstraps adaptive tags but I would prefer a "resolution switcher" button similar to what I see on various other sites showing "240, 480, 720, 1080" Is this possible to do automatically within the HTML5 video tag similar to the "CC Closed Captioning" button that appears when you add subtitle files ?

  I was trying to avoid using a custom player.

  This was my quick bootstrap solution but would prefer a button/switcher.

  <div class="hidden-xs">
  
      <video style="width:100%" autobuffer="autobuffer" controls="controls" poster="&lt;%= @video.attachment.url(:preview) %>"><source label="720" type="video/mp4" default="default"><source label="ogg" type="video/ogg"><source label="webm" type="video/webm"><track label="English" kind="subtitles" srclang="en" src="/assets/subtitles.vtt" default="default"><p>Your Browser does not support the video tag.</p></track></source></source></source></video>
  
  </div>
  
  <div class="visible-xs">
  
      <video style="width:100%" autobuffer="autobuffer" controls="controls" poster="&lt;%= @video.attachment.url(:preview) %>"><source label="360" type="video/mp4" default="default"><source label="ogg mobile" type="video/ogg"><source label="webm mobile" type="video/webm"><track label="English" kind="subtitles" srclang="en" src="/assets/subtitles.vtt" default="default"><p>Your Browser does not support the video tag.</p></track></source></source></source></video>
  
  </div>

• Facebook live video can only be previewed while streaming my Mac screen

  24 janvier 2017, par iownthegame

  I use the following ffmpeg command to share my screen streaming to Facebook.

  

  ffmpeg -f avfoundation -r 10 -video_size 352x288 -i "0" -c:v h264 -f flv 
  
  "rtmp://rtmp-api.facebook.com:80/rtmp/1269140699772419?ds=1&a=AaYsXcYcdHQrrrUF"

  then I can see the video preview scenes
  

  however, once I press the ’Go Live’ button, and go to my facebook page, I can find a post said I am Live Now. When I press the ’play button’, there are only black scenes that last for 1 2 seconds, and the video ends.

  

  And there is also a weird thing, the video can be played when I end up the live stream. When refreshing the page, I can find a post said I was Live, the video of this post can be played successfully.

  Anyone knows why the video can be watched when previewing and finishing live but not the exact live moment ?

  [updated]

  During the live streaming period, if I press the play button, there are only 1 2 seconds black scenes and the live stream ends.
  

  However if I press the video frame again, another modal pops up then I can see the live streaming. Is it a facebook bug ?
