  • ffmpeg : unsync audio after processing

    18 novembre 2013, par QuickSilver

    I am recording a video and using RecordRTC : WebRTC . After receiving the webm video and wav audio at server, I'm encoding it to a mp4 file using ffmpeg(executing shell command via php). But after encoding process, the audio is unsync with video (audio ends before video). How can I fix this ?

    js code is here

    ffmpeg command used is :

    ffmpeg -y -i 166890589.wav -i 166890589.webm -vcodec libx264 166890589.mp4

  • Manipulating one video into multi outputs with FFmpeg results in no audio in the last output

    27 octobre 2015, par my name is

    Using FFmpeg, I’m trying to do some filtering operations on one input video to scale it (out1), scale and trim it (out2).
    This is the command I’m using :

    ffmpeg -y \
    -i "Robotica_1080.mkv" \
    -filter_complex "[0:v]split=2[v1][v2]; \
    [v1]scale=640:360,setpts=PTS-STARTPTS[vout1]; \
    [v2]trim=10:15,scale=640:360,setpts=PTS-STARTPTS[vout2]; \
    [0:a]asplit=2[a1][a2]; \
    [a1]anull,asetpts=PTS-STARTPTS[aout1]; \
    [a2]atrim=10:15,asetpts=PTS-STARTPTS[aout2]; \
    [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
    [vout2][aout2]concat=n=1:v=1:a=1[out2]" \
    -map "[out1]" "1.mp4" \
    -map "[out2]" "2.mp4"

    1.mp4 is ok while 2.mp4 lasts 5 seconds as expected but without audio at all (the QuickTime inspector doesn’t write the audio codec)

    I tried to remove the trim/atrim filters, so the filter_complex parameter looked like this :

    -filter_complex "[0:v]split=2[v1][v2]; \
    [v1]scale=640:360[vout1]; \
    [v2]scale=640:360[vout2]; \
    [0:a]asplit=2[a1][a2]; \
    [a1]anull[aout1]; \
    [a2]anull[aout2]; \
    [vout1][aout1]concat=n=1:v=1:a=1[out1]; \
    [vout2][aout2]concat=n=1:v=1:a=1[out2]" \

    but still no audio on 2.mp4

    Can anyone give me a hint ?

    —EDIT—
    This is the output from first ffmpeg command :

  • Pipe breaks when piping gif to ffmpeg

    20 avril 2015, par forwardslash

    I’ve been trying to pipe gifs to ffmpeg to turn them into mp4s but I keep getting I/O errors from the pipe when I try.

    Something like

    cat nyan.gif | ffmpeg -f gif -i - -pix_fmt yuv420p -y nyan.mp4

    Outputs

    The important part being pipe:0: Input/output error

    I’ve tried this in bash and zsh on OSX and Ubuntu and I get the same error on all of them. I get the same error when trying to pipe with curl or httpie. When I just have file as input it works fine. Am I missing something necessary when piping to ffmpeg ?
