  • FFMPEG get ID3v2 tag size

    5 février 2016, par Riverchimp

    In ffmpeg is there a way to get the size of an ID3v2 tag ? When I open the song file with avformat_open_input ffmpeg prints out these logs.

    V/FFMPEG: Probing mp3 score:12 size:2048
    
V/FFMPEG: Format mp3 probed with size=2048 and score=50
    
V/FFMPEG: id3v2 ver:3 flags:00 len:1075646
    
V/FFMPEG: Skipping 0 bytes of junk at 1075656.

    I could parse these logs to get the size but I would prefer a more robust solution.

    avfilter/vf_gblur : add x86 SIMD optimizations

    The horizontal pass get 2x performance with the patch
    
under single thread.
    

    Tested overall performance using the command(avx2 enabled) :
    
./ffmpeg -i 1080p.mp4 -vf gblur -f null /dev/null
    
./ffmpeg -i 1080p.mp4 -vf gblur=threads=1 -f null /dev/null
    
For single thread, the fps improves from 43 to 60, about 40%.
    
For multi-thread, the fps improves from 110 to 130, about 20%.

  • How can i capture microphone stream and change with ffmpeg ?

    23 janvier 2020, par Emre Erol

    I am using ffmpeg for chancing wav file with below code on python ;

    song = subprocess.Popen(["ffmpeg", "-i", sys.argv[1], "-af", "asetrate=22050,aresample=44100,atempo=2", "-f", "wav", "pipe:1"],stdout=subprocess.PIPE)

    But i want to send microphone stream to this subprocess. How can i change sys.argv[1] to microphone stream data ?

    I am using pyaudoio library for capturing sound in python.
