  • Android and JNI, pipe data to FFmpeg

    2 décembre 2014, par William Seemann

    I’m trying to create a metadata retriever based on FFmpeg. Since raw Android application resources are often only accessible using a file descriptor I need a way to pipe this data to FFmpeg via JNI. I know FFmpeg supports a "pipe" protocol :

    UNIX pipe access protocol.
    

    
Allow to read and write from UNIX pipes.
    

    
The accepted syntax is: 
    

    
    pipe:[number]
    

    
number is the number corresponding to the file descriptor of the pipe (e.g. 0 for stdin, 1 for stdout, 2 for stderr). If number is not specified, by default the stdout file descriptor will be used for writing, stdin for reading.
    

    
For example: cat test.wav | ffmpeg -i pipe:0

    My question is, how do I programmatically emulate cat test.wav | ffmpeg -i pipe:0 using JNI and avformat_open_input using a FileDescriptor ? Is this possible ?

  • RFC 4175 support in ffmpeg ?

    28 novembre 2018, par Morix Dev

    As of today, is RFC 4175 (aka SMPTE 2110-20) currently supported in the released version of ffmpeg (4.1) ?

    Surfing the web I am only able to find these two references :

    But it is not clear to me if it has been merged into the released version or not...

    If so, are there some examples of ffmpeg / ffplay command lines for testing that ?

  • Java IO Streaming Large Files Video/Data/Sound [on hold]

    2 mars 2015, par James Relic

    I have a series of questions listed below regarding java.io streaming and sockets.

    1. What is a video streaming server ? How does it differ from a standard web server.

    2. Remember Napster/Morpheus etc ? They’re P2P programs, did they allow users to stream data to each other ? Is there a difference between streaming and downloading (on the clients end) ?

    3. How would you go about writing a generic program in java that streams anything to the client , word docs, mp3 files, videos files ? Would you use serverlets for this purpose ?

    4. If all you are doing is sending files video/sound/docs/text etc from one computer to another would you need to use specialist APIs like FFMPEG-Java, Red5 ?

    5. if you are sending video or sound as a file supposedly you don’t need to worry about encoding or decoding ?

    6. Do I need to worry about RTSP if im streaming videos as a file ? Rather then wanting them to play live on the client end ?

    I understand my questions sound very untechnical and basic, but I’m a little confused on this whole streaming topic and want to know the best way to stream large files of all types using the Java EE/Spring platform.
