  • Error using FFMPEG to create videos from a list of images

    3 août 2016, par user2308191

    I have a text file that contains the path of some images(the images are in order in the text file), the file looks like this :

    /home/Recording-Session-1456734351095_images/output_0001.png
    
/home/Recording-Session-1456734351095_images/output_0002.png
    
/home/annotations/rec_1456734351095/annotated_output_0003.png
    
.......

    I want to use ffmpeg to create a video from these images. Here is the command I am using :

    ffmpeg -framerate 20 -f image2 -i images.txt -c:v libx264 -r 20 -pix_fmt yuv420p out.mp4

    but it gives me this error :

    [image2 @ 0x32ce7a0] Could not find codec parameters for stream 0 (Video: none, none): unknown codec
    
Consider increasing the value for the 'analyzeduration' and 'probesize' options

    I tried different numbers for analyzeduration and probesize, but the error still exists, any idea what is the problem ?

  • FFMPEG av_read_frame() return an I/O error (-5) ?

    7 mars 2019, par vominhtien961476

    I’m using ffmpeg library to capture screen (desktop). Everything works fine when I run my app in debug/release mode. The I/O error comes when this app run in c# window service mode (win 10 OS). I googled but still don’t know why the error come. In the service mode there is no problem when connecting to some rtsp link (Camera) except desktop capture.

    AVInputFormat * pAVInputFormat = av_find_input_format("gdigrab"); 
    
if (pAVInputFormat != NULL) 
    
{ 
    
   int err = avformat_open_input(&pFormatCtx, "desktop", pAVInputFormat, NULL); 
    
   if(err== 0) 
    
   { 
    
      err = av_read_frame(&pFormatCtx, &packet); 
    
      if (err < 0) 
    
      { 
    
          char errs[AV_ERROR_MAX_STRING_SIZE]; 
    
          av_make_error_string(errs, AV_ERROR_MAX_STRING_SIZE, err ); 
    
          String^ errStr = gcnew String(errs); 
    
          WriteLog("Error in function av_read_frame() return = " + errStr); 
    
          return -1; 
    
     } 
    
   } 
    
}

    I have some problems with building ffmpeg for servestream radio.

    Here’s the log :

    export NDK=/home/vlad/android/ndk

    next :

    to

    TOOLCHAIN=`echo $NDK/toolchains/arm-linux-androideabi-4.9/prebuilt/linux-x86*`

    What’s wrong ?
