  • video hosting with PHP api or PHP script for social network project

    17 April 2014, by al404IT

    I have a project for a small social network where user can upload their videos, video should not be longer than 1 or 2 minutes but they need to be private and related to user that uploaded.

    Since uploaded video may be in many different format I have two options:

    • upload video and use ffmpeg to process them, can i find any PHP script that does that? PROS I have my files on my server and I'm not dependent from third party CONS I guess is a real intensive task and I may need a quite good noting plan since the beginning of this project

    • use a video hosting service that provide API to upload and process video, i actually find vzaar.com that may seems to do what I need. PROS Scalable CONS I rely on third party for my contents

    since the project is a small social network it may be interesting this too opusphp.com, but i never user or read about

    can Vimeo PRO suite my needs? Other suggestions?
    In future it may be necessary to add a basic video editing function to trim uploaded video setting starting and ending point

  • Library for decoding H.264 RTSP stream

    28 July 2015, by Saurabh Gandhi

    I was planning to decode H.264 based RTSP stream using FFMPEG in OpenCV but, when I tried so it gave some errors. Later, I found that many people have faced issues while decoding H.264 stream using ffmpeg (libavcodec). Typically the below mentioned error messages pop-up while using libavcodec:

    "[h264 @ 0xa766dd0]concealing 1200 DC, 1200 AC, 1200 MV errors"

    Has anyone used any other library successfully for decoding H.264 based RTSP. If so, which is the library (I have heard of live555 which is used within vlc player for decoding such streams). I would also like to know the output format and how it can be made compatible with OpenCV (typically within opencv we can use cvQueryFrame to directly extract a frame from a video stream, but in case we are using a library other than ffmpeg how to go about it).

    Thanks in advance.

  • FFMpeg- Raw compressed data to video

    21 August 2012, by p.streef

    I'm trying to use FFMpeg to create a video. So far i've been playing with a multiplexing example:
    http://ffmpeg.org/doxygen/trunk/muxing_8c-source.html, and i'm able to create a compressed video from an already existing video.

    Because my program is going to run on an embedded platform I would like to use some custom code (generated by a colleague) to compress the video data and place it into the video file.
    So I'm looking for a way to create a video file in c/c++ using ffmpeg in which i have full control over the compression part (to basically circumvent ffmpeg from doing the compression for me and inserting my own code).

    To clarify i'm planning to use this to save film from an intelligent camera into a compressed h264 mpeg-4 file.
