  • FFmpeg write silence if there is no data in pipe:0

    15 juillet 2023, par Oleksandr Petrenko

    I have an ffmpeg process that continiously writes PCM data from standard input to an mp3 file. The problem is that sometimes there can be pauses in data being sent to ffmpeg. Pauses may be very large, even up to an hour, but process is never closed. I want to get ffmpeg to write silence to file if there is no data in pipe:0. Is it possible to do only with ffmpeg or I need to implement it on my side ? If it is possible, then how can I do that ?
I tried to use some parameters and filters but I didn't found the thing I need.

    


    I'm new to ffmpeg and working with audio so I will be glad to see any assistance.

    


  • Is it possible to pipe ffmpeg's output to sox ?

    26 avril 2023, par Marcus

    I'm trying to generate a spectrogram with sox, from ffmpeg's output.

    


    I can do it in separate steps, but I'd like to do it in a single one. Is it possible ?

    


    When I try :

    


    ffmpeg -i input.m4a -f wav - | sox -t wav - -n spectrogram


    


    I get an error :

    


    sox WARN wav: Premature EOF on .wav input file


    


  • Output result of concat demuxer to pipe

    19 mars 2023, par ZPears

    I am trying to output the results of an ffmpeg call that concatenates videos to a pipe. Here's the command :

    


    ffmpeg -protocol_whitelist https,file,tls,tcp -f concat -safe 0 -i <(for f in "/path/to/file1.mp4" "/path/to/file2.mp4"; do echo "file $f"; done) -c copy -


    


    When I run this, I get Unable to find a suitable output format for 'pipe:'.

    


    From other searches, my understanding is that I need to specify an output format via the -f flag, but I'm not sure how to do that given that I already have output as my -f flag value.

    


    Does anyone have any tips for this ?
