Torchvision doesn't compile against ffmpeg-5 #5616
Description
🐛 Describe the bug
Steps to reproduce:
- Install torchvision nightly from conda:
conda install -y -c pytorch-nightly torchvision. This will also install ffmpeg-5 from conda - Compile torchvision from source:
python setup.py install - The compile fails with the following error:
