• videostreaming in java with bytedeco maven dependencies

  22 octobre 2020, par faenschi

  we try to setup a videostreamig service in java. our applications runs in a docker container on openshift. therefore we install ffmpeg in the dockerfile.

  


  in java we use the bytedeco maven dependencies. but i'm really not sure which dependency version runs with which ffmpeg version installed in the container. is there somewhere a overview ? does anybody have a similar setup ?

  


  at the moment we use the 1.5.4 maven dependencies and ffmpgen v4.3.1 in the container :

  


   <dependency>&#xA;        <groupid>org.bytedeco</groupid>&#xA;        <artifactid>javacv-platform</artifactid>&#xA;        <version>1.5.4</version>&#xA;    </dependency>&#xA;&#xA;    <dependency>&#xA;        <groupid>org.bytedeco</groupid>&#xA;        <artifactid>javacpp-platform</artifactid>&#xA;        <version>1.5.4</version>&#xA;    </dependency>&#xA;&#xA;   &#xA;    <dependency>&#xA;        <groupid>org.bytedeco</groupid>&#xA;        <artifactid>ffmpeg-platform</artifactid>&#xA;        <version>4.3.1-1.5.4</version>&#xA;    </dependency>&#xA;

  


  this does not work. the pod crashes as soon as i start the streaming. if i use ffmpeg v 3.x with a older centos base image and the dependency above the pod does not crash..but the streaming does not work either.

  


  any help appreciated

• Is there an effective and cheap/free way to host video for a mobile app that must be approved by an admin before going live ? [on hold]

  9 août 2013, par user2658775

  We are building a mobile app for the iOS and Android operating systems. The app is to be a communication platform for members within an organization. Content is generated by users and submitted to the admin. Once approved by the admin the content is pushed to the app. One feature of the app is the ability to upload video.

  We are having a tough time attempting to figure out the best way to do this. Because the app will be representing the organization, the organization must have control over the approval process.

  So far we have come up with the following options :

  Option 1 : purchase a dedicated server from hosting service provider. The basic package with Blue host is $150/month which is fairly expensive.

  Option 2 : have the users post to YouTube using their personal accounts. Upon posting to YouTube (via the app) the app would send a notification to the admin that a new video has been posted. Admin would review the video and if acceptable admin would user url link to post video to app. This option, while free, requires many steps that will bog down the submittal process.

  Does anyone know of an effective way to post video to an app that requires approval by an admin ?

• avformat/mpegtsenc : fix PCR generation intervals

  4 août 2019, par Marton Balint

  avformat/mpegtsenc : fix PCR generation intervals
  PCR generation was based on counting packets for both CBR and VBR streams.
  
  Couting packets might have worked for CBR streams (when muxrate was specified)
  
  but it only took into account the packets of a service (or the packets of the
  
  PCR stream lately), so even that was problematic for multi program streams.
  The new code works on actual timestamps for both CBR and VBR streams. For VBR
  
  streams the behaviour of the old code is simulated by selecting a PCR interval
  
  which is the highest multiple of the frame duration but still less than 100 ms.
  It should be trivial to add support for setting the PCR interval for VBR
  
  streams as well in a later patch.
  The accuracy of PCR packets for CBR streams was greatly improved by preemtively
  
  sending them at PCR intervals even if sending the payload of another stream
  
  is in progress.
  This may fix these tickets :

   #7524
