• Skiping MP4 video

  30 avril 2013, par M.Yazdian

  I like to create the video player to show videos on my website. I made a video player in flash CS5 and actionscript3 to stream the videos on the website.

  My videos are often flv or mp4 format.
  In the flv files I use flvmdi app to inject the metadata to that ,and for skipping the flv file I use xmoov-php (video player can pass the keyframe number from flv metadat to xmoov-php to create the new flv file from passed keyframe to the last flv keyframe, and return the flv video file on the php header for flash video player to show the video ).

  but about mp4 format in Xmoov-php wiki it says :
  this file can't support the mp4 format to skiping...!!!
  Now I need skiping the mp4 files in my video player (I like my viewers select a part of video before buffering all video on their browser and play it ).

  please give me a suggestion to skiping the mp4 file in the php or .net platform
  Many thanks

• why I can't compile x264 or ffmpeg downloaded from git

  4 avril 2013, par Monjura Rumi

  It has been just a few days that I am using x264, ffmpeg and trying to take help from codes in git. I am always having some peculiar problem. It seems like no one or few people faced such problems. Here is one of those problems. If I download x264 or ffmpeg using git then I could not compile that source code. At first terminal will show ./configure: Permission denied. Then If I change permission of configure file using chmod 755 command then it will show ./configure: /bin/bash^M: bad interpreter: No such file or directory. To build x264 and ffmpeg I have followed this link https://github.com/lince/libffmpeg-c/wiki. My attempt to compile x264 has failed. Can you please tell me how can one use source code downloaded from git ?

• PHP ffmpeg not found

  17 décembre 2020, par heisenberg

  so I already browse all the forum but I still get error "sh : 1 : /usr/bin/ffmpeg : not found".
If I run ffmpeg from terminal it works just fine and can do convert video without problem, but if I use PHP exec or shell_exec, the return always ffmpeg not found.

  


  this is my code :

  


  $cmd = "/usr/bin/ffmpeg";

$run = exec($cmd." -i 'linkvideo.m3u8' -bsf:a aac_adtstoasc -vcodec copy -c copy -crf 50 /test_stream/newfile.mp4 2>&1");

var_dump($run);


  


  if I run which ffmpeg or whereis ffmpeg from terminal it will return /usr/bin/ffmpeg, but if I exec('which ffmpeg') from my code it will return ffmpeg not found. I already chown and chmod the ffmpeg to grant rwx, i tried move ffmpeg to /usr/local/bin still same result. If i run whoami from terminal it will show root but if from my code using exec('whoami') it will show www-data so maybe I miss something about the user but I also already tried to chown ffmpeg from root to www-data still the result is ffmpeg not found, maybe anyone can help, I'm using codeigniter and already install ffmpeg in server using sudo apt-get ffmpeg, thanks before !
