• Inject FFMPEG video converter directly into .NET C# ?

  3 juillet 2021, par Mehdi Daustany

  How to implement FFMPEG in .NET Core C# ?

  


  I'm using FFMPEG as a batch file, I prepared a jobs queue, then Hangfire picks queue rows to sending to the batch file to starting convert by FFMPEG.

  


  I need to inform users by a progress bar, because of using FFMPEG as a CLI third-party, it is unachievable.
Is there any nuget package or any way to inject FFMPEG into .NET ?

  


• Fail build rav1e ffmpeg in ubuntu based Docker

  27 mai 2021, par Kodsama

  I a trying to build a Docker with ffmpeg which supports (encode/decode), av1, h26x, vpx. Everything runs fine apart the build for rav1e (if I comment out —enable-librav1e and the rav1e run part it goes through without problem).

  


  I could not find any specific other dependencies which are needed for the built.

  


  Any idea what is missing ?

• Transcoding with the GCP Transcoder API results in a time gap

  3 mars 2021, par banyan

  I've been trying GCP's Transcoder API and having trouble with the time randomly becoming shorter than specified in certain cases.

  


  The specific cases are as follows :

  


  

  1. Specifying startTimeOffset and endTimeOffset (cut off 2 seconds before and after the video)

  


  2. fMP4 is used as container

  


  3. input video is mp4 with screen recording on iPad Pro

  


  


  For example, if I don't specify startTimeOffset and endTimeOffset, the time will not be shortened. Also, there is no problem when MPEG2-TS is specified for container. There may be a problem with the video itself, but I haven't found a clue how to set it up.

  


  I'm not sure whether this is a problem with the Transcoder API or with me.

  The following is a ffprobe of the resulting manifest file, which is 2 seconds shorter than specified. (expected : 00:02:47.00, actual : 00:02:45.00) In this case, it's a 2-second gap, but it can be 10 seconds or 30 seconds, and it varies from video to video.
