• ffplay crashed on HLS streaming with toggled -an and -vn options

  19 septembre 2016, par oleg_otvorot

  When I try to start silent(without audio and video streams) playing of HLS (HTTP Live Streaming) by typing

  ffplay -an -vn -i "http://localhost:8080/video/find?startTime=
  
  1376716800000&endTime=1376717400000 

  I get the next error message on my console :

  Is this bug or feature that ffplay can’t playing video without audio/video stream ? I need to run ffplay programmatically from my java test application to view loadout of my service.

  P.S : I also tried adding the options "-nodisp -an", but that provided the same result as mentioned above.

• FFmpeg : Error occurred while encoding audio stream from ac3 to aac

  4 décembre 2015, par akki_2891

  I am using following command to encode my video to h264 and aac audio codec :

  I am really not able to find what possibly could be wrong. I dont want to copy audio codec , i wish to encode it from ac3 to aac

  Also any suggestion to make it lossless

• Ffmpeg not fully functioning

  26 août 2014, par Joshua

  Hello i have problem with ffmpeg i’m using phpvibe cms already asked in their forums but they don’t know the answer which leads me that it’s probably my fault so the problem is when i upload :

  6 seconds avi video which weights 817 KB it uploads perfectlly plays like it should run.

  However when i try upload 12mb avi sample i see that it does not work in folder where should be that video converted it shows 0kb size

  That means it didn’t start converting somewhow i think this is ffmpeg issue also i have spoted that my ffmpeg is placed in /usr/local/bin/ and in phpvibe cms systems there is different location for ffmpeg it looks like this : Img link

  Why when i upload small avi video it converts good and when i try longer it fails maybe it converts while upload process is going on but than why it shows 0b in folder where converted videos should be placed ?

  P.s i tried couple avi videos that weights more than 10 mb same thing and my code for ffmpeg conversation is :

  $output ="{ffmpeg-cmd} -i {input} -vcodec libx264 -s {ffmpeg-vsize} -threads 4 -movflags faststart {output}.mp4";

  Also tried :

  output ="{ffmpeg-cmd} -i {input} -vcodec libx264 -s {ffmpeg-vsize} -threads 4 {output}.mp4 2>&1";

  Same thing + im using Debian 7 Wheezy. Thanks !

  EDIT :

  i have made a test script it gives this output :
