• I am trying to generate thumbnail by using ffmpeg but I can not define pathways and make my codes work

  17 juillet 2020, par D. Merchant

  Fffmpeg modul is installed in my shared hosting.

  


  

  


  My goal is to get a thumbnail of a video. My codes is in below. I can not make them work. This is my first time I use ffmpeg.

  


  require 'vendor/autoload.php';

$video_path = 'home/sasasasasa/public_html/wp-content/uploads/jvhyicpzxy.mp4';

$ffmpeg = FFMpeg\FFMpeg::create();
$video = $ffmpeg->open($video_path);
$video
    ->frame(FFMpeg\Coordinate\TimeCode::fromSeconds(5))
    ->save('new_preview1.jpg');


  


  When I try the codes in the above, I get this error :

  


  

  


  1- What does 'vendor/autoload.php' pathway mean ? I can not see a folder called "vendor" in my file manager.

  


  2- I've check my ffmpeg folder with this code "exec('which ffmpeg') ;" and it outputs "/usr/bin/ffmpeg". But there is no directory in my file manager like that. After a search, Ive found this directory about ffmpeg : "/perl/usr/lib/perl5/FFmpeg". If I enter this path in my hosting, I can see only "Command.pm" and "Thumbnail.pm". What is my wrong, and how can I make my codes work and have a preview of the video ?

  29 juillet 2020, par karma

  I've read the following link, and did :

  


  youtube-dl --rm-cache-dir


  


  But it still give me 403 forbidden.

  


  This is my process :

  


  youtube-dl -g https://www.youtube.com/watch?v=kGDgGsrA78s


  


  It gave me a result like this :

  The result gave me two URL, so I only copy the first line and since what I want is just to copy a few minutes video portion - so in ffmpeg :

  


  ffmpeg -ss 00:00:15.00 -i https://r2---sn-uigxxi0ujipnvo-q2ne.googlevideo.com/videoplayback?expire=1596034295&ei=lzghX6SHKMOD8QPlx5SQBw&ip=223.255.228.87&id=o-AK6cYo88zJXe5Xb4y1QsXspuRnVCy-zPFpMaHcAaTQ-_&itag=140&source=youtube&requiressl=yes&mh=DA&mm=31%2C29&mn=sn-uigxxi0ujipnvo-q2ne%2Csn-npoe7nlz&ms=au%2Crdu&mv=m&mvi=2&pl=24&initcwndbps=173750&vprv=1&mime=audio%2Fmp4&gir=yes&clen=22077901&dur=1390.039&lmt=1521818817521456&mt=1596012582&fvip=5&keepalive=yes&fexp=23883098&c=WEB&sparams=expire%2Cei%2Cip%2Cid%2Citag%2Csource%2Crequiressl%2Cvprv%2Cmime%2Cgir%2Cclen%2Cdur%2Clmt&sig=AOq0QJ8wRQIhANHMaZK4jYg7p4t2dID3d21VRv18I1nhBtXqYRSZo0C7AiAEjO8LwjhXeNQiKqdiZFQ_DsHuXT4rgvPnNQhaDGj9hg%3D%3D&lsparams=mh%2Cmm%2Cmn%2Cms%2Cmv%2Cmvi%2Cpl%2Cinitcwndbps&lsig=AG3C_xAwRAIgAIwAVMPrcMhAL476uN_ZzWj8vKPGGW58KCpHBYBsKeICICRgVWgthNvgbGl8VgQwscjJ0n8ib4XBNjRxRgSg2T5r&ratebypass=yes -t 00:00:10.00 -c copy out.mp4

  BTW, I've also tried to copy the second URL, still 403 error.
  
I also tried to copy both URL, still 403 error.

  


  On the other hand, when I tried to paste the URL into Internet Download Manager,
  
IDM directly recognized the URL and I can download the file via IDM.

  


  Is there a way to resolve this ?
  

  


  Any kind of respond would be greatly appreciated.
  
Thank you in advanced.

  


  EDIT :
I'm very sorry for my ignorant.
  
It turn out I need to put apostrophe at the beginning and at the end of the URL :).

  


  Dear moderator, please close this thread.
  
Thank you for you all.

  


• FFmpeg still running but don't render HLS file in WPF application [closed]

  22 octobre 2020, par anhpt233

  I had apply ffmpeg to my wpf app with C# for live streaming and split it for upload to the server. But I has a problem with this command. It's will stop render hls file after more than 30m. And when I check process in task manager, ffmpeg.exe still running with 0% CPU and memory.

  


  I had change "preset" to "ultrafast" and config "rtbufsize" is 100M, but it's can't resolve this problem.

  


  I think maybe the client was out-of-memory, not sure. But I don't know how optimal or fix this issue. Anybody can help me ? Thanks so much !

  


  Here is my code :

  


  ffmpeg -f dshow -framerate 30 -i video="Logitech HD Webcam C270":audio="Microphone (HD Webcam C270)" -y - rtbufsize 100M - f gdigrab - framerate 30 - probesize 10M - draw_mouse 1 - i desktop -filter_complex  "nullsrc = size = 1440*480 [base];[0:v]setpts = PTS - STARTPTS ,scale = 720*480 [upperleft] ; [1:v]setpts = PTS - STARTPTS,scale = 720*480 [upperright];[base][upperleft]overlay = shortest = 1:x = 0:y = 0[tmp1];[tmp1][upperright]overlay = shortest = 1:x = 720:y = 0" -c:v libx264 -crf 23 -force_key_frames "expr: gte(t, n_forced * 2)" -preset veryfast -tune zerolatency -pix_fmt yuv422p -f hls -hls_time 4 -hls_playlist_type vod -start_number 0 -hls_segment_filename index%d.ts 480p.m3u8
