• Heroku : FFMpeg installed but php worker can't find it

  4 décembre 2019, par Greco Jonathan

  Context

  I’ve a RabbitMQ’s queue that contains AMQPMessage, those messages are referencing a video that needs to be treated (cut essentially and encoded in x264 also)

  Here’s the code that cause the issue (pretty straightforward)

          $ffprobe = FFProbe::create([
  
              'ffmpeg.binaries'  => '/usr/bin/ffmpeg',
  
              'ffprobe.binaries' => '/usr/bin/ffprobe',
  
          ]);

  Error Message

  TL ;DR :
  Error: "Unable to load FFProbe"

  [2019-12-03 14:55:07] messenger.ERROR : Error thrown while handling message App\Api\Message\AMQPvideoFFMPEG. Sending for retry #1 using 1000 ms delay. Error : "Unable to load FFProbe" "message" :"[object] (App\Api\Message\AMQPvideoFFMPEG : {})","class" :"App\Api\Message\AMQPvideoFFMPEG","retryCount":1,"delay":1000,"error" :"Unable to load FFProbe","exception" :"[object] (Symfony\Component\Messenger\Exception\HandlerFailedException(code : 0) : Unable to load FFProbe at /app/vendor/symfony/messenger/Middleware/HandleMessageMiddleware.php:80, FFMpeg\Exception\ExecutableNotFoundException(code : 0) : Unable to load FFProbe at /app/vendor/php-ffmpeg/php-ffmpeg/src/FFMpeg/Driver/FFProbeDriver.php:50, Alchemy\BinaryDriver\Exception\ExecutableNotFoundException(code : 0) : Executable not found, proposed : /usr/bin/ffprobe at /app/vendor/alchemy/binary-driver/src/Alchemy/BinaryDriver/AbstractBinary.php:160)" []

  Configuration & tests

  On Heroku I’ve 2 dynos :

  - web $(composer config bin-dir)/heroku-php-nginx -C config/packages/dev/heroku_nginx.conf public/
  
  - worker php bin/console messenger:consume ffmpeg 

  On this platform, I’ve also 3 buildpacks, look below, with this specific buildpack :

  

  To make sure that all is available here’s the results of my checks :

  This code is working well on another platform (handled by kubernetes), so it may need some adjustments with heroku. But can’t find it.

  Why this error since my configuration is not showing any missconfigurations ? What am I missing here ?

• Open letter to the European Parliament’s LIBE committee

  28 novembre 2019, par Joselyn Khor — Uncategorized

  An open letter to the European Parliament’s LIBE committee

  

  In an effort to stem the tide of external control over user privacy, Matomo has rallied with other like-minded companies like Protonmail, NextCloud, Tutanota and Mailfence, to advocate for pro-privacy changes to the European Commission’s “e-evidence” proposal.

  Excerpt from the letter : 

  “The Commission’s e-evidence proposal threatens the competitive advantage European tech businesses have over their American counterparts by undermining the protections we can provide to our customers. It breaks with the long-standing rule that only trusted national judicial authorities can order companies to hand over customer data for criminal investigations. Instead, the Commission’s e-evidence proposal would allow any foreign law enforcement agency from across the EU to force us to hand out customer data without our own authorities doublechecking the foreign order.

  “Different from American Big Tech firms, European privacy tech companies lack the resources to verify the legality of each foreign order. Because of the way the e-evidence proposal is phrased, we would not even be able to properly authenticate foreign authorities to ensure that we are not replying to a malicious actor – let alone object to an order if we found it to be unwarranted.”

  Matomo Founder, Matthieu Aubry emphasises, “It is time that privacy-minded tech companies work together to defend their users, their businesses, and the values they are founded on. This is why we are supporting Privacy Tech Europe.”

• Frozen images at the beginning of a mts to mp4 conversion

  26 novembre 2019, par nounou

  I am trying to convert a file h264 mpegts to h264 mp4.

  ffmpeg.exe -i input.mts -f mp4 -vf "scale=512:384 " -c:a aac -b:a 64k  -c:v libx264   -pix_fmt yuv420p -movflags faststart -map 0:v -map 0:a  -y  output.mp4

  This conversion produces an output file longer than the input file and the image freezes (around 1 second) at startup, but there is already sound
  After about 1 second the picture and sound are synchronous.
  I have these messages before transcoding :

  If I try to cut the first 3 seconds on the source file.

   ffmpeg.exe -ss 3 -i input.mts -f mpegts -c:v copy -c:a copy -map v -map a input_ss3.mts

  Then redo the conversion h264 mpegts to h264 mp4
  I have the same result.

  For the moment, in order to have an output file without frozen images at the beginning ; i need to do the following :

  I have to extract the video and sound, look for the delay betwen video and sound, cutting sound at the begining of audio file,
  concatenate the audio file et the video file, then convert to h264 - mp4.

  ffmpeg.exe -ss xx -i input.mts  -f mpegts -c:a copy -vn audio.mts
  
  ffmpeg.exe -i input.mts  -f mpegts -c:v copy -an video.mts
  
  ffmpeg.exe -i audio.mst -i video.mts   -f mpegts  -c:v copy -c:a copy -map 1:v -map 0:a  new_input.mts
  
  ffmpeg.exe -i new_input.mts -f mp4 -vf "scale=512:384 " -c:a aac -b:a 64k  -c:v libx264   -pix_fmt yuv420p -movflags faststart -map 0:v -map 0:a  output.mp4

  Can you tell me if there is a way to fix the source file or if there is another way to do it ?

  Maybe I should cut my source file to the first intra image and do the conversion afterwards.

  ffmpeg.exe input.mts -ss first_intra_frame  -f mpegts -c:v copy -c:a copy -map v -map a:0 new_input.mts
  
  ffmpeg.exe -i new_input.mts -f mp4 -vf "scale=512:384 " -c:a aac -b:a 64k  -c:v libx264   -pix_fmt yuv420p -movflags faststart -map 0:v -map 0:a  output.mp4

  But I have to find the exact position of the first intra frame.

  I try with the command :

  ffmpeg.exe -skip_frame nokey -i input.mts -t 10  -vf showinfo -vsync 0 -f null -

  But, I get "pts_time" which does not seem to match the position in "seconds.milliseconds" of the first intra frame.

  I try with the command :

  ffprobe.exe  input.mts -show_frames  -select_streams v:0  -show_entries frame=pkt_pts,pkt_pts_time,pkt_dts,pkt_dts_time,pkt_pos,coded_picture_number,pict_type > input.txt

  I also do not find the position of the first intra frame.

  Could you help me to find the exact position in "seconds.milliseconds" of the firsts intra frames ?
