I need to encode a flac file with seektables, ffmpeg's flac encoder does not include seektables, so I need to use the flac CLI. I'm trying to make it possible to convert any arbitrary audio file to a seekable flac file by first piping it through ffmpeg, then to the flac encoder.
17/05/2014 · It's possible that GCC 4.9.0 could be miscompiling something, but that can swing both ways - FFmpeg could be getting miscompiled by 4.9.0, or whatever FLAC encoder you used FLAC itself, FFmpeg, Flake, etc. was miscompiled or is outputting streams with header errors that FFmpeg's decoder can now detect. 13/05/2018 · I'm working on a shell script to encode the audio files in a given directory and output.flac files to another directory.
