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

    17 avril 2014, par 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

  • Java library for converting MP4 to MPEG-2 TS in memory ?

    30 avril 2014, par Lane

    SO...

    I have a Java FX application that runs an embedded HTTP Live Streaming server for video playback using the Media class (NOT live streaming, video on demand). The video playback consists of multiple files that are actually storing a collection of RTP packets. When my HttpHandler is called to handle the get request for the files (entries in the .m3u8 index file), I plan on...

    • Loading the file into memory
    • Creating a byte array of the RAW H264 packets
    • Convert (wrap ?) the RAW H264 to a MPEG-2 TS (ffmpeg -i video.h264 video.ts)
    • Write the MPEG-2 TS contents to the response body so that it can be played

    ...one of my requirements is that I am not able to create local files, even temp ones. So I cannot create a .h264 file, use ffmpeg to create a .ts file, read the ts file and then write the contents to the response body.

    As far as I can tell, Xuggler does not work with streams and JCodec is slow. I am fairly confident that I can dig into and understand the MPEG-2 TS format and simply convert the RAW H264 into the appropriate format, but this seems like a lot of needless work that should have been done before.

    Anyone know of a simple way to convert RAW H264 to MPEG-2 TS ? Or MP4 to MPEG-2 TS ? I can use MP4Parser to create the MP4 data in memory quickly, I just need a java library that can generate MPEG-2 TS data, thanks !
