Re: [FFmpeg-user] Is it possible to speed up merging-speed from HD to LAN?
Maybe he doesn't know that releases are not meant for end-users and have many disadvantages? Ok, I am now very confused about that. If the releases are not for end users? What (or which version) is mentioned to be used by end users?

[FFmpeg-user] WAV to FLAC md5 mismatch errors
Hello, I am using FFMPEG to convert WAV files to FLAC files and I am getting MD5 mismatch errors when running the converted files through AudioTester. Now, it doesn't happen for all converted files, just some. Conversely, when I use the flac encoding tool to encode the files, they do not produce the md5 mismatch error. Does anyone have any insights on this?
