• Stream Video from Raspberry Pi to my Webpage

  21 septembre 2016, par velu4689

  I want to live stream the video captured on my SJ 4000 Camera.

  The Camera is Connected to my Rpi by Wi-Fi and the stream is available using the following address : rtsp ://192.168.1.254/sjcam.mov

  Now, I want to watch this stream in my webpage by using a Streaming Engine on Raspberry Pi.

  The rtsp ://Camera addr works when I Connected the Camera directly to my Windows PC and attempted using VLC. But I wanted to do it by using Rpi as the streaming engine.

  I have attempted the following :

  1) Using ffmpeg -i "rtsp ://[IP_ADDR]" -vcodec -f http://[my_pc_IP_ADDR]
  But am getting an error message "Unable to find a suitable output format for ’http://192.168.55.39:5678".

  2) Installed OMX Player. But I do not find proper material to stream using OMX Player.

  3) Have come across GStreamer. But still the same problem..I did not find proper material.

  Kindly provide your valuable inputs.

  Thanks.

• Animated Gif using PHP 5 and ffmpeg [closed]

  1er décembre 2012, par user1828200

  I make an Animated Gif, by download a video from youtube with youtube-dl and then convert it into AVI with ffmpegand then make animated gif through convert. It works, but speed is very slow.

  Here is my code

  Youtube Download :

  shell_exec("youtube-dl -o JNJNoaIU7qs.flv --format=5 --audio-quality=9 http://www.youtube.com/watch?v=JNJNoaIU7qs);

  Convert to AVI , because I want to make Small Gif so time manipulation is not done with youtube-dl thats why i convert avi with time manipulation

  shell_exec("ffmpeg -i JNJNoaIU7qs.flv -sameq -ss 00:00:5 -t 00:00:10 JNJNoaIU7qs.avi");

  Make Gif

  shell_exec("convert -quiet -delay 0  JNJNoaIU7qs.avi JNJNoaIU7qs.gif"); 

  It creates the GIF files, but it is very slow, how can I increase the speed of conversion ?

• How to make mp4 rendering visible on Mac ?

  24 octobre 2022, par János

  Generating mp4 from gif like this :

  


      await new Promise<void>((resolve, reject) => {&#xA;        ffmpeg&#xA;            .input(`/tmp/input_${name}.gif`)&#xA;            .outputOptions([&#xA;                &#x27;-c:v libx264&#x27;,&#xA;                &#x27;-movflags &#x2B;faststart&#x27;,&#xA;                &#x27;-movflags frag_keyframe&#x2B;empty_moov&#x27;,&#xA;            ])&#xA;            .noAudio()&#xA;            .output(`/tmp/output_${name}.mp4`)&#xA;            .on(&#x27;end&#x27;, () => {&#xA;                console.log(&#x27;MP4 video generated&#x27;)&#xA;                resolve()&#xA;            })&#xA;            .on(&#x27;error&#x27;, (e) => {&#xA;                console.log(e)&#xA;                reject()&#xA;            })&#xA;            .run()&#xA;    })&#xA;</void>

  


  will generate mp4, but can be watch only in Chrome, not in Safari or Quicktime Player.

  


  We tried many other option like this :

  


  '-pix_fmt yuv420p',
'-vf "scale=trunc(iw/2)*2:trunc(ih/2)*2"',


  


  but it raise an error :

  


  Error reinitializing filters!
Failed to inject frame into filter network: Invalid argument
