Déploiements possibles
31 janvier 2010, parDeux types de déploiements sont envisageable dépendant de deux aspects : La méthode d’installation envisagée (en standalone ou en ferme) ; Le nombre d’encodages journaliers et la fréquentation envisagés ;
L’encodage de vidéos est un processus lourd consommant énormément de ressources système (CPU et RAM), il est nécessaire de prendre tout cela en considération. Ce système n’est donc possible que sur un ou plusieurs serveurs dédiés.

How to embed an MP4 inside a PDF ?
19 août 2020, par malatI am a happy user of img2pdf. This tool does the minimal amount of work to put a series of JPEG 2000/JPEG/PNG images into a PDF "enveloppe". However I am now faced with a new challenge : embed a MP4 file into a PDF "enveloppe".


I see that commercial tool can do it, as seen at :




Here is one such sample PDF file (no Flash required on windows in this sample) :

** https://gitlab.com/agrahn/media9/uploads/90fddd777e0ec514c39c924cd8d3b688/video_test.pdf




It seems to have been introduced in ISO 32000-1 (PDF 1.7 Extension Level 5)


I am looking for a solution which will use the Rich Media annotation inside the PDF stream.


There are dozen of duplicated questions on superuser/stackoverflow, which all pretty much refer to imagemagick/convert command line tool. But in my case,
convert
expand the images into a multi-page PDF (which is not my desired behavior) :

$ convert input.mp4 output.pdf

Using ffmpeg for stream encryption by srtp in windows
11 avril 2015, par user3248865I have been trying to make encrypted stream via ffmpeg and I´ve found srtp support in this library (ffmpeg documentation). Unfortunately, it seems that encryption doesn´t work at all. I´m using the following command to send stream :
ffmpeg -re -i "output.mpg" -vcodec libx264 -f flv "srtp://192.168.0.100:7777?srtp_out_suite=AES_CM_128_HMAC_SHA1_80&srtp_out_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"
and this one for stream receiving :
ffplay "srtp://192.168.0.100:7777?srtp_in_suite=AES_CM_128_HMAC_SHA1_80&srtp_in_params=00108310518720928b30d38f41149351559761969b71d79f8218a39259a7"
They work good.
But, If I change the command for ffplay to this one :ffplay udp://192.168.0.100:7777
it works too and I can watch the video. So, it means that encryption for srtp doesn´t work ?
- Is the stream encryption by using ffmpeg possible (not only srtp) ?
- If so, What am I doing wrong ?
Thanks in advance.
