Original prompt

TITLE: Debugging Dockerfile for FFmpeg Build with GPU Support

USER INTENT: The user aims to troubleshoot errors encountered while building FFmpeg in a Docker environment, specifically focusing on potential issues with the Dockerfile or the environment configuration, and to ensure that the build process outputs GPU information.

TASK DESCRIPTION: The user is attempting to build FFmpeg with GPU support using a Dockerfile. They want to identify the cause of the build failure, which is related to the missing libvmaf library, and ensure that the build process correctly outputs GPU-related information.

EXISTING: The user has a Dockerfile that attempts to install necessary dependencies and build FFmpeg with specific configuration options for GPU support. The build process has been initiated but fails due to a missing library.

PENDING: The user needs to resolve the issue with the missing libvmaf library and ensure that the build process outputs GPU information during execution. They may need to modify the Dockerfile to include the installation of libvmaf or adjust the configuration options.

CODE STATE:

• Dockerfile: The relevant section of the Dockerfile includes commands to install dependencies and configure FFmpeg:

  RUN set -eux; \
      apt-get update || true; \
      apt-get install -y --no-install-recommends pkg-config libass-dev libfdk-aac-dev libx264-dev libx265-dev libvpx-dev libmp3lame-dev libopus-dev libopenjp2-7-dev libssl-dev gobjc || true; \
      git clone https://githubfast.com/FFmpeg/FFmpeg.git /workspace/build/FFmpeg; \
      cd /workspace/build/FFmpeg; \
      git checkout ${FFMPEG_TAG}; \
      ./configure \
       --enable-nonfree \
       --enable-cuda-nvcc \
       --enable-libnpp \
       --extra-cflags="-I/usr/local/cuda/include -I/usr/local/cuda/include -I/usr/local/include" \
       --extra-ldflags="-L/usr/local/cuda/lib64 -L/usr/local/cuda/compat" \
       --disable-static \
       --enable-shared \
       --enable-libvmaf; \
      make -j$(nproc); \
      make install; \
      ldconfig

RELEVANT CODE/DOCUMENTATION SNIPPETS:

• Error message indicating the missing library:

  ERROR: libvmaf >= 2.0.0 not found using pkg-config
  

OTHER NOTES: The user has expressed the need for GPU information to be printed during the build process, which may require additional commands in the Dockerfile to check for GPU availability or configuration. The user should also consider ensuring that libvmaf is installed in the Docker image before attempting to build FFmpeg.
