Чего ожидать
- FLV files can contain either MP3 or AAC audio - only FFmpeg's stream-copy mode (
-c:a copy) avoids re-encoding; VLC and most GUI tools always re-encode. - The output quality cannot exceed the source: a 64 kbps FLV will not produce a better-than-64-kbps MP3 regardless of the encoder setting.
- The video track is discarded entirely; keep the original
.flvif you may need the video later.
Часто задаваемые вопросы
Will converting FLV to MP3 lose quality?
Not if the FLV already holds an MP3 track and you use FFmpeg with
-c:a copy - the output is bit-for-bit identical. A re-encode (required when source audio is AAC) adds only a small, usually inaudible loss.How do I know what audio codec is inside my FLV?
Run
ffmpeg -i input.flv without specifying an output file; FFmpeg prints stream details including whether the audio is mp3 or aac.Can I convert multiple FLV files at once?
Yes - FFmpeg supports batch scripting, and GUI tools like FormatFactory and Freemake Video Converter include a built-in batch queue.
What if my FLV file has no sound?
If
ffmpeg -i input.flv shows no audio stream, the file is video-only and there is nothing to extract as MP3.Программы, которые конвертируют FLV: Aimersoft DRM Media Converter for Windows · Aimersoft iTransfer for Windows · FormatFactory · Free Studio · Freemake Video Converter · Hamster Free Video Converter · iPad Video Converter Factory Pro · MediaCoder
