Probably not, even if there was an increase it shouldn’t be much more than twice at its worst > On Feb 5, 2019, at 12:15 PM, Zoltan Kerenyi Nagy > <kerenyi.nagy.zol...@gmail.com> wrote: > > The CPU usage is still abobe 90% with libshine.

I am suspicious of the while loop with the fifo. Pretty sure it wouldn’t do what you want, there would be a break in the audio every five minutes. Maybe you could use the segment muxer? ffmpeg -f alsa -i hw:0,0 http://localhost:4444/audio.ffm <http://localhost:4444/audio.ffm> -ar 44100 -f segment -strftime 1 -segment_time 300 %Y-%m-%d__%H_%M.wav Only thing is it wouldn’t create the directory structure. _______________________________________________ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
