  sample HLS stream url,"http://localhost/cam/live1.m3u8"

  willing add mpegts stream option.. I don`t want to run one more service for mpeg-ts creation like ffserver or vlc.. Anyone guide me to achieve this goal.

  expected transport stream url "http://localhost/cam/live1.ts"

• PHP Shell Excution of ffmpeg Not Reading Bash Profile

  25 juillet 2015, par Searay330

  I understand that is a odd question and may be very specific, but I recently installed ffmpeg on a shared hosting service. While I can execute all tasks from an SSH console, when making the exact same call in PHP, I get this error.

  error while loading shared libraries : libavdevice.so.56 : cannot open shared object file : No such file or directory

  It did the same thing in PuTTY, until I updated the ~/.bash_profile with this line :

  export LD_LIBRARY_PATH=/home/searay330/ffmpeg/lib

  Does PHP not use ~/.bash_profile, or is there a different file that needs to be updated ? Any information on this topic is greatly appreciated, thank you.

• How to upload object to a bucket in Google Cloud Platform from Python script

  7 juillet 2016, par Bryan

  The goal of this script is to extract audio from a video file using ffmpeg and upload it into a bucket on Google Cloud Platform each time it is called. Eventually I will have to extract audio from a large list of videos, so ideally I would want my script to extract and subsequently upload it into the cloud.

  My confusion is how to use GCP API to upload my object into a bucket. Any advice would be greatly appreciated !
