• playing http video url using ffmpeg

  17 mai 2012, par Ranjith

  I am using libavcodec of ffmpeg to play a http video stream in my application.
  I have implemented my own video player for this.This player is working fine.

  Now, I want to show buffering status of video (what percentage of video is downloaded by ffmpeg). But I could not find any api or event for this.

• Excluding ARMv5 and ARMv6 devices from Google Play

  14 mai 2015, par Taras

  I build a ffmpeg based library for my project and the outputs are really huge. Is it OK to remove the support of old arm processors and leave only arm-v7 and x86 libraries ?

  I suspect that arm-v7 won’t work on older arm processors.

  The application min sdk is 4.0.3 and the question is whether the percentage of devices with old ARM is too small so I can filter them out on Google Play ?

• Laravel MySQL DB not updating after long process

  11 mai 2022, par slanginbits

  I'm doing some video encoding using Laravel and FFMpeg using https://github.com/protonemedia/laravel-ffmpeg

  


  During the video conversion, I can perform some db updates to update the percentage complete in hls_percent field :

  


          $ffmpeg_cmd = FFMpeg::fromDisk('local_videos')
            ->open($video->filename)
            ->exportForHLS()
            ->toDisk('local_videos')
            ->setSegmentLength(3) // optional
            ->setKeyFrameInterval($key_interval) // optional
            ->onProgress(function ($percentage, $remaining = 0, $rate = 0) use ($id) {
                ItemVideo::where('id', $id)->update(['hls_percent' => $percentage]);                
            });


  


  This process works fine and the hls_percent value gets updated to 100 and the encoded video files are generated.

  


  After some files are moved, (takes several seconds) a final db update is not done.

  


  ItemVideo::where('id', $id)->update(['hls_complete' => 1]);


  


  The timeout only happens while encoding a large 150MB (10 min duration) mp4 file. Smaller/shorter videos complete the process without any issues.

  


  I have increased the following in php.ini

  


  memory_limit = 512M 
post_max_size =  1024M
upload_max_filesize = 1024M
max_execution_time = 2400
max_input_time = 2400
default_socket_timeout = 2400


  


  I modified the global variables in the MySQL database server to higher timeouts
as instructed here https://sebhastian.com/lost-connection-mysql-server-during-query/

  


  connect_timeout 2400
delayed_insert_timeout 300
have_statement_timeout YES
innodb_flush_log_at_timeout 1
innodb_lock_wait_timeout 50
innodb_rollback_on_timeout OFF
interactive_timeout 28800
lock_wait_timeout 31536000
mysqlx_connect_timeout 30
mysqlx_idle_worker_thread_timeout 60
mysqlx_interactive_timeout 28800
mysqlx_port_open_timeout 0
mysqlx_read_timeout 30
mysqlx_wait_timeout 28800
mysqlx_write_timeout 60
net_read_timeout 2400
net_write_timeout 2400
replica_net_timeout 2400
rpl_stop_replica_timeout 31536000
rpl_stop_slave_timeout 31536000
slave_net_timeout 2400
ssl_session_cache_timeout 2400
wait_timeout 28800


  


  apache2handler :

  


  Max Requests Per Child : 0 - Keep Alive : on - Max Per Connection : 100
Timeouts Connection : 300 - Keep-Alive : 5

  


  I'm not getting an error messages in laravel or /var/log/apache2/error.log

  


  What else am I missing ? How can I keep the MySQL connection alive to make the final update ?
