  • ffmpeg critical noise occured after silence remove filtering

    31 mars 2020, par SY KIM

    I’ve tried to remove silence duration in my audio file.
    and it seems like working well..
    but some problem rose up like the picutre i attached.

    ffmpeg -i "D://mono_test/silenceremove_test_raw.mp3" -filter:a silenceremove=1:0:-66dB -b:a 192k "D://mono_test/silenceremove_test.mp3"

    after silence remove filtering(in ffmpeg), some noise occured like picture(just left channel in the file). already control all parameters about silenceremove method, but the problem doesn’t disappear.

    any Ideas ?

    please help me..
    thnx.

  • ffmpeg DASH encoding : always getting bitrate as 200k for vp9 codec

    29 novembre 2019, par Saurabh

    I am using following command, earlier put here : to generate DASH files :

    ffmpeg -y -nostdin -loglevel error -i "$1" \
           -map 0:v:0  -map 0:v:0 -map 0:v:0  -map 0:v:0  -map 0:v:0  -map 0:v:0 -map 0:a\?:0  \
           -maxrate:v:0 350k -bufsize:v:0 700k -c:v:0 libx264 -filter:v:0 "scale=320:-2"  \
           -maxrate:v:1 1000k -bufsize:v:1 2000k -c:v:1 libx264 -filter:v:1 "scale=640:-2"  \
           -maxrate:v:2 3000k -bufsize:v:2 6000k -c:v:2 libx264 -filter:v:2 "scale=1280:-2" \
           -maxrate:v:3 300k -minrate:v:3 100k -bufsize:v:3 600k -c:v:3 libvpx-vp9 -filter:v:3 "scale=320:-2"  \
           -maxrate:v:4 1088k -minrate:v:4 200k -bufsize:v:4 2176k -c:v:4 libvpx-vp9 -filter:v:4 "scale=640:-2"  \
           -maxrate:v:5 1500k -minrate:v:5 300k -bufsize:v:5 3000k -c:v:5 libvpx-vp9 -filter:v:5 "scale=1280:-2"  \
           -use_timeline 1  -use_template 1 -adaptation_sets "id=0,streams=0,1,2 id=1,streams=3,4,5 id=2,streams=a" \
           -threads 8 -crf 3 -seg_duration 5 -hls_init_time 1 -hls_time 5 -hls_playlist true -f dash "$2"

    The issue is, in the output, I always get bandwidth as 200k for vp9 codec(see output below), while for same video bandwidth for h264 codec varies as par resolution and quite less, I expected vp9 to be even less as it compresses more. I have tested using multiple different options like : -b:v, -deadline, -cpu-used -crf, etc, but not working expected with different values of these, What am I missing ?

  • amix filter is causing audio to disappear

    21 novembre 2019, par Mason

    I’m trying overlay audio onto a video. I have a very simple ffmpeg command (auido.mp3 is much longer than the video)

    ffmpeg -i video.mp4 -i audio.mp3 -filter_complex "[0:a] [1:a] amix=duration=shortest [a]" -map 0:v -map [a] test.mp4

    This produces a silent video. However, when not mapping the video stream

    ffmpeg -i video.mp4 -i audio.mp3 -filter_complex "[0:a] [1:a] amix=duration=shortest [a]" -map [a] test.mp4

    The resulting audio file is as expected.

    What could be causing this issues ?

    (Is there a better way to overlay audio onto a video via ffmpeg ?)
