• Working directory in Dockerfile is not what is expected to be

  31 mai 2022, par user1765862

  I have following Dockerfile

  


  FROM public.ecr.aws/lambda/dotnet:6 AS base

FROM mcr.microsoft.com/dotnet/sdk:6.0-bullseye-slim as build
WORKDIR /src
COPY ["AWSServerless.csproj", "AWSServerless/"]
RUN dotnet restore "AWSServerless/AWSServerless.csproj"

WORKDIR "/src/AWSServerless"
COPY . .
RUN dotnet build "AWSServerless.csproj" --configuration Release --output /app/build

FROM build AS publish

RUN apt-get update && apt-get install -y apt-utils libgdiplus libc6-dev

RUN apt-get install -y ffmpeg

RUN dotnet publish "AWSServerless.csproj" \
            --configuration Release \ 
            --runtime linux-x64 \
            --self-contained false \ 
            --output /app/publish \
            -p:PublishReadyToRun=true  

FROM base AS final
WORKDIR /var/task

CMD ["AWSServerless::AWSServerless.LambdaEntryPoint::FunctionHandlerAsync"]
COPY --from=publish /app/publish .


  


  As per ffmpeg docs In order to use ffmpeg I need to set its binary folder
for example with

  


  {
  "BinaryFolder": "/var/task",
  "TemporaryFilesFolder": "/tmp"
}


  


  Error

  


  


  An error occurred trying to start process './ffmpeg' with working
directory '/var/task'. No such file or directory

  


  


  What is the working directory here ?

  


  Update :
Actual error is being thrown when I try to execute following command (FFMpegCore package) from my api controller

  


  public class MyController : ControllerBase&#xA;{&#xA;    public async Task<string> Get()&#xA;    {    &#xA;         await FFMpegArguments&#xA;               .FromPipeInput(new StreamPipeSource(myfile))&#xA;               .OutputToPipe(new StreamPipeSink(outputStream), options => options&#xA;                  .WithVideoCodec("vp9")&#xA;                  .ForceFormat("webm"))&#xA;                  .ProcessAsynchronously();&#xA;         ...&#xA;    }    &#xA;}&#xA;</string>

  


• Support building C++ files with MSVC

  13 avril 2017, par Aaron Levinson

  Support building C++ files with MSVC
  Made appropriate changes to be able to successfully
  
  build C++ files using a Visual C++ build on Windows.
  Based on an earlier patch by Kyle Schwarz.
  Comments :
  — compat/w32pthreads.h : Made appropriate changes to w32pthreads.h to
  
     get it to build when it is being included in a C++ file and built
  
     with Visual C++.  This is mostly a copy of Kyle Schwarz's patch as
  
     described above.
  — configure :
  
  a) Now calling set_ccvars CXX to cause the various CXX_ variables to
  
     be setup properly.  For example, with MSVC (Microsoft Visual C++),
  
     this causes CXX_O to be set to -Fo$@ instead of using the default
  
     value.  The default value does not work with Visual C++.  This
  
     change will also have the impact of correcting CXX_O (and possibly
  
     CXX_C) for other compilers, although this is really only relevant
  
     for the Intel compiler, in addition to MSVC.
  
  b) Now using cl for the C++ compiler for the MSVC toolchain.  This is
  
     currently only relevant for building the
  
     Blackmagic/Decklink-related files under avdevice.

• How to setup FFMPEGInterop to Use DRM playready

  1er novembre 2019, par marinamovies32

  I am using FFMPEGInterop class to play UWP video. I need to play it with playready setup but am running into issues.

  I can play playready with just mediaplayerelement and creating the protection manager, but when I create a FFMPEGMSS to stream it, than it fails. Says value is out of range when adding the protection manager to the MediaStreamSource.

  var StreamSource = FFmpegMSS.GetMediaStreamSource();
  
  var protectionManager = new Windows.Media.Protection.MediaProtectionManager();
  
  Windows.Foundation.Collections.PropertySet cpSystems = new Windows.Foundation.Collections.PropertySet();
  
  cpSystems.Add("{F4637010-03C3-42CD-B932-B48ADF3A6A54}", "Microsoft.Media.PlayReadyClient.PlayReadyWinRTTrustedInput"); //Playready
  
  protectionManager.Properties.Add("Windows.Media.Protection.MediaProtectionSystemIdMapping", cpSystems);
  
  protectionManager.Properties.Add("Windows.Media.Protection.MediaProtectionSystemId", "{F4637010-03C3-42CD-B932-B48ADF3A6A54}");
  
  protectionManager.ServiceRequested += ProtectionManager_ServiceRequested;
  
  protectionManager.ComponentLoadFailed += ProtectionManager_ComponentLoadFailed;
  
  
  
  protectionManager.Properties.Add("Windows.Media.Protection.MediaProtectionContainerGuid", "{9A04F079-9840-4286-AB92-E65BE0885F95}");
  
  
  
  var supportsHardwareDrm = PlayReadyStatics.CheckSupportedHardware(PlayReadyHardwareDRMFeatures.HardwareDRM);
  
  if (!supportsHardwareDrm)
  
  {
  
      protectionManager.Properties["Windows.Media.Protection.UseSoftwareProtectionLayer"] = true;
  
  }
  
  Windows.Storage.ApplicationDataContainer localSettings = Windows.Storage.ApplicationData.Current.LocalSettings;
  
  
  
  Header.Text = supportsHardwareDrm ? "SUPPORTED" : "NOT SUPPRTED";
  
  
  
  StreamSource.MediaProtectionManager = protectionManager;
  
  
  
  mediaElement.Source = MediaSource.CreateFromMediaStreamSource(StreamSource);

  I should be able to play playready DRM with a setup protection manager to start but down get any info on it so confused on the next step for it.
