  • using FFMPEG with silencedetect to remove audio silence

    8 octobre 2016, par Zahlii

    I am trying to use the following command with the latest ffmpeg build to remove silence from my .mp3 files:

    ffmpeg -i SILENCE.mp3 -af silencedetect=n=-50dB:d=1 -y -ab 192k  SILENCE_OUT.mp3

    However, the following output is produced:

    The generated audio file however still has the original length without any silence removed. See the following images: http://i.imgur.com/nVxe5lX.png

    Any help is appreciated!

    EDIT: Alright, silence detect is only DETECTING the silence. Not removing it. I will try to post a solution for this.

  • ffmpeg - Continuously stream webcam to single .jpg file (overwrite)

    8 octobre 2016, par Germanunkol

    I have installed ffmpeg and mjpeg-streamer. The latter reads a .jpg file from /tmp/stream and outputs it via http onto a website, so I can stream whatever is in that folder through a web browser.

    I wrote a bash script that continuously captures a frame from the webcam and puts it in /tmp/stream:

    while true
do
    ffmpeg -f video4linux2 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 -vframes 1 /tmp/stream/pic.jpg
done

    This works great, but is very slow (~1 fps). In the hopes of speeding it up, I want to use a single ffmpeg command which continuously updates the .jpg at, let's say 10 fps. What I tried was the following:

    ffmpeg -f video4linux2 -r 10 -i /dev/v4l/by-id/usb-Microsoft_Microsoft_LifeCam_VX-5000-video-index0 /tmp/stream/pic.jpg

    However this - understandably - results in the error message:

    [image2 @ 0x1f6c0c0] Could not get frame filename number 2 from pattern '/tmp/stream/pic.jpg'
av_interleaved_write_frame(): Input/output error

    ...because the output pattern is bad for a continuous stream of images.

    Is it possible to stream to just one jpg with ffmpeg?

    Thanks...

  • FFMPEG to both save a file and stream to MPLayer on a different computer

    8 octobre 2016, par Laurent Bazinet

    Here's what i'm trying to do: Have a raspberry pi grab a video with a camera, using raspivid and pipe this directly to my main computer, which would act as a kind of server, by both saving the video, and allowing a live stream using MPlayer to be displayed by another computer on the network.

    My problem is only on the last part: display the stream on another computer.

    For clarity, Main computer is going to be Comp-A, and the computer running MPlayer will be Comp-X (because this can be any computer on my network, or even outside my network)

    If we follow the information, here's how i've done it so far: Grab the video and pipe it to the network (this is done on the raspberry pi)

    raspivid -t 0 -w 1280 -h 720 -a 12 -ih -v -fps 30 -n -o - | sudo nc -k -w 1 -l 80

    This works great for my purpose.

    Next, on Comp-A, I'm grabbing this stream with FFMPEG, and tee-ing to both a file and a UDP stream using this command:

    ffmpeg -i tcp://raspberryIP:80 -c:v h264 -f tee -map 0:v "[f=stream_segment:segment_wrap=25:segment_time=3600:reset_timestamps=1]output%%03d.mp4|[f=mpegts]udp://maincomputerIP:80"

    (side note, the [f=stream_segment:segment_wrap=25:segment_time=3600:reset_timestamps=1] is to have 25 videos of 1 hour long, and looping)

    Then I run into issues.

    If I run this on Comp-A: mplayer -fps 200 -demuxer mpegts "udp://Comp-A-IP:80" It works great.

    If I run the same command on Comp-X, it doesn't work.

    If I change the [f=mpegts]udp://Comp-A-IP:80" to [f=mpegts]udp://Comp-X-IP:80", then the Comp-X works, but the Comp-A doesn't anymore.

    This leads me to believe my issue is that the UDP url from FFMPEG is asking for the computer it's going to connect to, not the host computer.

    My problem is that Comp-X's IP is unknown.

    Is there a way? Maybe I'm over-complicating things. I don't know.

  • how to output gif with same size as input video

    7 octobre 2016, par Maxlight

    I am following How do I convert a video to GIF using ffmpeg, with reasonable quality?

    It gives example:

    ffmpeg -i input.flv -i palette.png -filter_complex "fps=10,scale=320:-1:flags=lanczos[x];[x][1:v]paletteuse" output.gif

    However I want the gif output to be the same size as video and not 320 as specified here so I removed scale=320:-1 so I have

    ffmpeg -i input.flv -i palette.png -filter_complex "fps=10,flags=lanczos[x];[x][1:v]paletteuse" output.gif

    When I run that I get:

    No such filter: 'flags' Error initializing complex filters.

    If I remove:

    -filter_complex "fps=10,flags=lanczos[x];[x][1:v]paletteuse"

    Then it works but quality of the video is bad. So it seems that I must use a scale for those palette flags to work, how can I get ffmpeg to output gif same size as input video?

  • Issue when streaming some TV channels threw ffMpeg

    7 octobre 2016, par Raphael Serievic

    I am trying to stream a TV Tuner feed with ffMpeg through udp.

    The ffMpeg command line I use is the following :

    ffmpeg.exe -i udp://@239.255.255.9:1234 -map 0:p:1317:0 -profile:v baseline -crf 30 -preset ultrafast -vcodec libx264 -r 25 -vf scale=720:576-b:v 500k -f rtp udp://10.150.112.107:15048/ -map 0:p:1317:1 -acodec pcm_mulaw -strict experimental -ar 8k -ac 1 -b:a 128k -f rtp udp://10.150.112.107:15032/

    Where:

    • 1317 is the program id (channel)
    • 10.150.112.107 is where I want to stream the TV channel
    • 239.255.255.9 is where I receive the original TV channel's feed from my TV Tuner

    My problem is that with some program IDs it is working and with some others it is not : it is working with 1572 ("channel 10 hd") but not with 1317 ("7flix Sydney").

    The output of this command-line for channel 1572 (where it works) is the following :

    C:\Program Files (x86)\Tuner Manager\ServerModule> ffmpeg.exe
 -i udp://@239.255.255.7:1234 -map 0:p:1572:0 -profile:v baseline -crf 30 -prese
