  • ffmpeg convert video in a path with different name

    16 mars 2019, par tour travel

    Using ffmpeg in php with shell_exec and want to convert video in a path that different with where script is run. php script is in /s/m/video.php :

    <?php
    if(isset($_GET["videoTools"])){

       $user = $_GET["user"];
       $uid = $_GET["uid"];
       $vid = $_GET["vid"];

       $uploaddir = '/seller/uploads/'.$user.'/'.$uid.'/';

       echo shell_exec('ffmpeg -i '.$uploaddir.$vid.'-vid.mp4 -i /s/m/logo.png \
       -filter_complex "hflip[flipped];[flipped]overlay=x=20:y=20" \
       -s 480x320 -acodec aac -strict -2 -ac 1 -ar 16000 -r 13 -ab 32000 -aspect 3:2 \
       -strict -2 '.$uploaddir.$vid.'-vid-resized.mp4');
    }
    ?>

    And this script called by ajax in /s/a/index.php :

       $.ajax({
           url: "/s/m/video.php?videoTools",
           type: "GET",
           data: {vid: json[0], uid: json[1], user: json[2]},
           success: function(data){
            // success
           }
       });

    And for example I want to convert video in this path /s/uploads/91/768/2019-2-2_668-vid.mp4

    Problems :

    This not working, because look like ffmpeg not find video and logo in a path / Also look like ffmpeg not accepet video with - or _ or etc.

    No related error log, but video not generated and script not working. Any idea ?

  • ffmpeg x11grab to streamable format

    2 juin 2021, par Jintor

    2 FFMPEG process

    


    (1) generating a ffmpeg x11grab to a .mp4
(2) take the .mp4 and restream it simultaneously to multiple rtmp endpoints

    


    ISSUE the generated file in (1) have this error "moov atom not found"

    


    This is the command that generate (1) :

    


    ffmpeg -re -y -f x11grab -draw_mouse 0 -framerate 30 
-video_size $RESOLUTION -i :$DISPLAY_NUM -c:a aac -c:v libx264 
-movflags +faststart -preset ultrafast -crf 28 -refs 4 -qmin 4 
-pix_fmt yuv420p -filter:v fps=30 file.mp4


    


    in the (2) => when I try to ffmpeg -i file.mp4 output somewhere : I get "moov atom not found" so the (2) can't read or open (1).

    


    What I'm I missing

    


    in (1) -movflags +faststart doesn't seem to fix the issue

    


    ••••••• EDIT : more details on the context ••••••

    


    I'm using openvidu : webrtc with kurento and coturn.

    


    The record feature creates a .mp4 on the fly as the chat is going on.

    


    To start the recording, there is an API call i can make to my server and it automatically stops when all users leaves the chatroom OR do an other api call to stop. see composed video in this link https://docs.openvidu.io/en/2.17.0/advanced-features/recording/

    


    openvidu have also webhooks.

    


    My problem is not how to stop ffmpeg, but getting FFMPEG to encode while the mp4 or other is being generated "on the fly".

    


    There is 2 options :

    


    OPTION 1 : individual => 1 .webm per camare => this .webm ffmpeg can restream as hls or RTMP => it's working.

    


    OPTION 2 : ** but the issue is with "Composed" video => it's using ffmpeg to x11grab the session... but it's mp4 without moov ato, so ffmpeg don't do anything with this.

    


    see the composed.sh script here
https://github.com/OpenVidu/openvidu/blob/master/openvidu-server/docker/openvidu-recording/scripts/composed.sh

    


    ***************** EDIT 3 *************

    


    in the .sh this is the part that is creating the mp4

    


    ffmpeg -y -f alsa -i pulse -f x11grab -draw_mouse 0
-framerate $FRAMERATE -video_size $RESOLUTION -i :$DISPLAY_NUM
-c:a aac -c:v libx264 -preset ultrafast
-crf 28 -refs 4 -qmin 4 -pix_fmt yuv420p
-filter:v fps=$FRAMERATE "/recordings/$VIDEO_ID/$VIDEO_NAME.$VIDEO_FORMAT"

    


    How can I modify this to have better result example VP8 or VP9 with good quality .webm so that the ffpmeg second command(2) can encode it live...

    


    **** EDIT 4 ********

    


    I tried this it worked for 30 seconds and suddenly stopped

  • Open VideoStream using OpenCV 4.5.1 works on Windows but fails on Docker python:3.9.2-slim-buster for specific IP cam

    18 mai 2021, par Qua285

    I have 2 ip cameras - one of Hikvision and another of Provision ISR. Both use Onvif and work on VLC.&#xA;I've written a simple python script to record images every 5 sec from their video stream.&#xA;On Windows 10, using VSCode they both work as expected. Once deployed to a Docker container, my script works as expected with the Hikvision but fails with the Provision ISR - it doesn't open the stream.

    &#xA;

    Running python -c "import cv2; print(cv2.getBuildInformation())" on windows (venv 3.9.2) and on docker machine bring slightly different results but it's beyond my understanding to take something out of it...&#xA;Here is the Windows one :

    If relevant, the docker is installed on an Intel NUC with Ubuntu Desktop 20.04

    &#xA;

    If relevant, this is the dockerfile I've used to build the image :

    &#xA;

    FROM python:3.9.2-slim-buster as builder&#xA;&#xA;# Keeps Python from generating .pyc files in the container&#xA;ENV PYTHONDONTWRITEBYTECODE=1&#xA;# Without this setting, Python never prints anything out.&#xA;ENV PYTHONUNBUFFERED=1&#xA;&#xA;RUN pip install --upgrade pip&#xA;COPY ./Cam/requirements.txt .&#xA;RUN pip install -r requirements.txt&#xA;RUN apt-get update&#xA;RUN apt-get install ffmpeg libsm6 libxext6 -y&#xA;&#xA;WORKDIR /app&#xA;&#xA;FROM builder&#xA;COPY ./Cam .&#xA;CMD ["python", "camStreamer.py"]&#xA;

    &#xA;

    and last, this is the script code (simplified) :

    &#xA;

    I apologize for the very long post. Hopefully someone can put me on the right direction...
