Can ffmpeg convert audio to raw PCM? If so, how?

I'm currently using ffmpeg to convert FLV/Speex to WAV/pcm_s16le, successfully. However, I now need the output format to be RAW, that is, PCM signed 16-bit little endian, without the WAV header. I tried the following:

ffmpeg -y -i input.flv -vn -acodec pcm_s16le output.raw

But ffmpeg responds with:

Unable to find a suitable output format for 'output.raw'

I also tried using output.pcm and output as output file names, with the same result.

I also tried the -f flag to specify raw format, but that gives:

Unknown input or output format: raw

Is this possible with FFmpeg? If so, how?

Solution

  • Give this a shot:

    ffmpeg -i input.flv -f s16le -acodec pcm_s16le output.raw

    You can get these options by running:

    ffmpeg -formats
