• Unable to build solution in Visual Studio 2019 : The BaseOutputPath/OutputPath property is not set for project

  23 juillet 2022, par mhadi

  In an effort to integrate FFmpeg with Unity, I have been trying to build a solution file in Visual Studio 2019. However, I am currently unable to resolve the following error when I try to build in Visual Studio :

  


  


  The BaseOutputPath/OutputPath property is not set for project
'FFmpegUnityInterop.vcxproj'. Please check to make sure that you have
specified a valid combination of Configuration and Platform for this
project. Configuration='Release' Platform='x64'. This error may
also appear if some other project is trying to follow a
project-to-project reference to this project, this project has been
unloaded or is not included in the solution, and the referencing
project does not build using the same or an equivalent Configuration
or Platform.

  


  


  I have tried a number of solutions, including :

  


  

  1. Manually adding the OutputPath in 'FFmpegUnityInterop.vcxproj'
<outputpath>bin/Build/</outputpath>.

  


  2. In the FFmpegUnityInterop.vcxproj file, moving the ProjectProperty with my preferred configuration and platform combination to the very top of the list of ProjectProperties (there are 8 of them).

  


  3. Building with different configuration and platforms.

  


  4. Trying to build from VS Dev Command prompt using the following command :
MSbuild.exe "FFmpegUnityInterop.sln" /p:Configuration=Release /p:Platform="x64", as well as from the Visual Studio IDE.

  


  5. Tried setting the OutputPath in the command line command
(>MSbuild.exe FFmpegUnityInterop.sln /p:Configuration=Release /p:Platform="AnyCPU" /p:OutputPath = bin\Debug), only to have
MSbuild throw error MSB1008 (MSBUILD : error MSB1008 : Only one
project can be specified.)

  


  6. Setting the configuration and platform manually in the Configuration Manager GUI in
Visual Studio.

  


  


  I may have missed an attempted solution or two above, but I've tried most of the suggestions I found online, only to get the error pasted above. Part of me suspects that my compilation of FFmpeg libraries didn't execute fully, but I unfortunately do not have enough experience to verify that. Any suggestions to resolve this would be much appreciated.

  


  PS. The project was developed privately by a private entity that is currently unreachable

  


• lavc/libopenh264enc : set slice_mode option to deprecated

  29 avril 2020, par Linjie Fu

  lavc/libopenh264enc : set slice_mode option to deprecated
  "slice mode" option seems to be unnecessary since it could be
  
  determined by -slices/max_nal_size.
  default :        SM_FIXEDSLCNUM_SLICE mode with cpu-number slices.
  
   slices N :      SM_FIXEDSLCNUM_SLICE mode with N slices.
  
   max_nal_size :  SM_SIZELIMITED_SLICE mode with limited size slices.
  Add FF_API_OPENH264_SLICE_MODE macro to remove this option after
  
  LIBAVCODEC_VERSION_MAJOR = 59.

   One of the configured repositories failed (DAG RPM Repository),
  
   and yum doesn't have enough cached data to continue. At this point the only
  
   safe thing yum can do is fail. There are a few ways to work "fix" this:
  
  
  
       1. Contact the upstream for the repository and get them to fix the problem.
  
  
  
       2. Reconfigure the baseurl/etc. for the repository, to point to a working
  
          upstream. This is most often useful if you are using a newer
  
          distribution release than is supported by the repository (and the
  
          packages for the previous distribution release still work).
  
  
  
       3. Disable the repository, so yum won't use it by default. Yum will then
  
          just ignore the repository until you permanently enable it again or use
  
          --enablerepo for temporary usage:
  
  
  
              yum-config-manager --disable dag
  
  
  
       4. Configure the failing repository to be skipped, if it is unavailable.
  
          Note that yum will try to contact the repo. when it runs most commands,
  
          so will have to try and fail each time (and thus. yum will be be much
  
          slower). If it is a very temporary problem though, this is often a nice
  
          compromise:
  
  
  
              yum-config-manager --save --setopt=dag.skip_if_unavailable=true
  
  
  
  failure: repodata/repomd.xml from dag: [Errno 256] No more mirrors to try.
