# ffmpeg-free is Fedora's standard FFmpeg build (no libx264, but includes
# libopenh264, h264_vaapi, h264_nvenc, and h264_qsv).  This matches the
# working host environment exactly.  Do NOT swap this for RPM Fusion's
# `ffmpeg` package: it ships a different FFmpeg version with libx264, and
# libx264's output currently causes Discord to drop the stream after one frame.
