  input : Add a workaround for swscale overread bugs
  swscale can read past the end of the input buffer, which may result in
  
  crashes if such a read crosses a page boundary into an invalid page.
  Work around this by adding some padding space at the end of the buffer when
  
  using memory-mapped input frames. This may sometimes require copying the
  
  last frame into a new buffer on Windows since the Microsoft memory-mapping
  
  implementation has very limited capabilities compared to POSIX systems.

  lavu/hwcontext_qsv : make qsv hwdevice works with oneVPL
  In oneVPL, MFXLoad() and MFXCreateSession() are required to create a
  
  workable mfx session[1]
  Add config filters for D3D9/D3D11 session (galinart)
  The default device is changed to d3d11va for oneVPL when both d3d11va
  
  and dxva2 are enabled on Microsoft Windows
  This is in preparation for oneVPL support

• FFMpeg on docker

  31 mai 2022, par user1765862

  I'm trying to run FFMpegCore library in the docker
Here is my 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

#fix for using System.Drawing.Common on docker
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 .


  


  When I try to use any of FFMpegCore commands I'm getting following error in the log

  


  


  System.ComponentModel.Win32Exception (2) : An error occurred trying to
start process 'ffmpeg' with working directory '/var/task'. No such
