community/ffmpeg: IPFS support uses hardcoded fallback gateway
In FFmpeg 5.1, support for playing video content from IPFS was introduced. While the underlying functionality (IPFS playback) is fine, the use of a hardcoded IPFS web gateway is a security problem as the domain can become malicious in the future.
Accordingly, I am publishing an NMU to revert the hardcoded IPFS web gateway patch.
