| # Note: we're not setting BUILD_AGAINST_ALL_FFMPEG_FROM_S3 here, so | |
| # we're building libtorchcodec against the installed FFmpeg version | |
| # (from conda-forge) instead of building against our pre-built non-GPL | |
| # FFmpeg libraries. | |
| # The reason we need this is because the C++ tests decode x264 files. | |
| # x264 support is not LGPL, os it is not supported by our | |
| # pre-built non-GPL FFmpeg libraries. And if we were to build against | |
| # those, this is also what the tests would be loading at run time, | |
| # then failing when we try to decode x264. | |
| # To remediate that, we build against the FFmpeg that we installed | |
| # from conda-forge (which is able to decode x264), and that's also | |
| # what gets loaded at run time. | |
| # The Python tests are also decoding x264 files, and are built against | |
| # our non-GPL FFmpeg. And yet they pass. This is because in Python | |
| # we're able to distinguish between build-time (non-GPL FFmpeg) and | |
| # run time (conda-forge FFmpeg). | |
