  • Capturing PCM audio data stream into file, and playing stream via ffmpeg, how ?

    11 avril 2015, par icarus74

    Would like to do following four things (separately), and need a bit of help understanding how to approach this,

    1. Dump audio data (from a serial-over-USB port), encoded as PCM, 16-bit, 8kHz, little-endian, into a file (plain binary data dump, not into any container format). Can this approach be used :

      $ cat /dev/ttyUSB0 > somefile.dat

    Can I do a ^C to close the file writing, while the dumping is in progress, as per the above command ?

    1. Stream audio data (same as above described kind), directly into ffmpeg for it to play out ? Like this :

      $ cat /dev/ttyUSB0 | ffmpeg

    or, do I have to specify the device port as a "-source" ? If so, I couldn’t figure out the format.

    Note that, I’ve tried this,

    $ cat /dev/urandom | aplay

    which works as expected, by playing out white-noise..., but trying the following doesn’t help :

    $ cat /dev/ttyUSB1 | aplay -f S16_LE

    Even though, opening /dev/ttyUSB1 using picocom @ 115200bps, 8-bit, no parity, I do see gibbrish, indicating presence of audio data, exactly when I expect.

    1. Use the audio data dumped into the file, use as a source in ffmpeg ? If so how, because so far I get the impression that ffmpeg can read a file in standard containers.

    2. Use pre-recorded audio captured in any format (perhaps .mp3 or .wav) to be streamed by ffmpeg, into /dev/ttyUSB0 device. Should I be using this as a "-sink" parameter, or pipe into it or redirect into it ? Also, is it possible that in 2 terminal windows, I use ffmpeg to capture and transmit audio data from/into same device /dev/ttyUSB0, simultaneously ?

    My knowledge of digital audio recording/processing formats, codecs is somewhat limited, so not sure if what I am trying to do qualifies as working with ’raw’ audio or not ?

    If ffmpeg is unable to do what I am hoping to achieve, could gstreamer be the solution ?

    PS> If anyone thinks that the answer could be improved, please feel free to suggest specific points. Would be happy to add any detail requested, provided I have the information.
