• PHP : Return response immediately, but run multiple lengthy shell_exec functions in the background

  15 janvier 2016, par Jake

  I am creating a simple web service that accepts a video upload, runs multiple different encodes on the video (mp4, webm, ogv), and then uploads the newly created files to our video host.

  Let’s say I have multiple commands..

  shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1280x720 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1280x720.mp4');
  
  
  
  shell_exec('ffmpeg -i input.mp4 -f mp4 -c:v libx264 -preset slow -crf 24 -s 1920x1080 -c:a libfdk_aac -profile:a aac_he -ar 22050 -b:a 64k -movflags +faststart output-1920x1080.mp4');
  
  
  
  shell_exec('ffmpeg -i input.mp4 -f ogg -c:v libtheora -q:v 5 -s 1280x720 -c:a libvorbis -ar 22050 -b:a 64k -movflags +faststart output-1280x720.ogv');
  
  
  
  shell_exec('ffmpeg -i input.mp4 -f ogg -c:v libtheora -q:v 5 -s 1920x1080 -c:a libvorbis -ar 22050 -b:a 64k -movflags +faststart output-1920x1080.ogv');

  In summary, I want to...

  1. Print an immediate response : success : true
  2. Kick off multiple ffmpeg jobs synchronously.
  3. After each job is complete, send a POST to another server (one POST for each shell_exec).

  It would also be nice to only send the POST if the job was successful, but I could easily work around that by just checking to see if the output file exists on the server.

  I know that I can force shell_exec to run in the background by simply appending >/dev/null 2>/dev/null & to each command — which would allow me to print a response immediately — but I think by doing this, this would cause all of the jobs to run in parallel, and also, since this is diverting the output, I do not get any true callbacks when jobs are complete.

  Any ideas ??

• VB Dot Net ffMpeg Network Web Server Cannot Execute JS Ajax Call to Private Web Server When Client is Outside Network

  29 septembre 2019, par Sonbelt

  I have a solution that is using Windows Server 2008 (Web Server), Windows Server 2008 (MS Sql Database Server), Computer with Windows 10 Home with IIS acting as a file server that runs command line calls where ffMpeg converts video files to html5 compliant files and then puts them on the NAS (a WD Network Drive.). Users then use the public website to view the videos streamed from the NAS.

  Windows Server 2008 cannot make a command line call to ffMpeg. If it could the performance hit would be too large.

  In order to get the public web server to call a private web page I’m using an Ajax post call to the file server web site. That site converts the videos and then there is a separate routine that moves the files using the same methodology. In order to get the file server where it can move the files to the NAS I’ve set the application pool identity to a specific user. The public web server is using the Network Service as the identity for the application pool.

  When I run the pages on the public server from behind the firewall where the calling ip address is in the same network the solution works fine but when I use any device or browser when the calling ip address is not in the local network the JS Ajax call to the private web site does not work. No lines appear in the IIS log on the file server.

  I’ve tried changing to the other built in choices and set the identity as the administrator on the public web server. Turned off the public server firewall, turned off the private files server firewalls without success.

  The solution needs to work when the calling ip address is not in the local network. I apologize for long post. Can you help me please ?

• My ExoPlayer Is opening Streams but no audio

  21 décembre 2019, par Oni

  I have created an app to play some m3u8/ts urls with exoplayer version 2.10.5
  The urls play good but some of them has only video but no audio and some other urls it works as it should, having both video and audio. Some of the urls on vlc say that have aac audios and those links seems to play both video and audio. The app struggles play both audio and video on a part of the streams with mp2 audio, there are other streams with mp2 audio which play both audio and video. Thats why i don’t know what is going on, on audio mp2 40% of the links i have tried work good, and some of mp2 60% do not work with audio.
  the debug
