  • Put image over video and save video to sd card Android

    25 juillet 2016, par Ronak Thakkar

    I’m working on a feature in which I want to add picture over the video and save it to sd card.

    in general, user selects an image with semi transparent background and puts that image above the video, after user presses the save button he gets a new video but already with image above the video.

    I have heard about ffmpeg, and saw some commands that are provided by ffmpeg. but i don’t know from where I should initialize. can anyone provide me any example for the same.

    Thank you.

  • Revision e905da6f9c : Allocate four |zcoeff_blk| for sub8x8 contexts. The RD and load save/code grabs

    24 juillet 2015, par Alex Converse

    Changed Paths :
     Modify /vp9/encoder/vp9_context_tree.c



    Allocate four |zcoeff_blk| for sub8x8 contexts.

    The RD and load save/code grabs it as groups of four. In practice there
    is no change to physical allocations becaquse this is backed by a 16-byte
    memalign.

  • JavaCV grab frame method delays and returns old frames

    27 janvier 2019, par Null Pointer

    I’m trying to create a video player in Java using JavaCV and its FFmpegFrameGrabber class. Simply, Inside a loop, I use

    .grab() to get a frame and then paint it on a panel

    Problem is, player gets delayed. For example, after 30 seconds passes, in video only 20 seconds passes.

    Source is ok. Other players can play the stream normally. Problem is possibly the long printing time.

    What I do not understand is that : "why does .grab() method brings me a frame from 10 seconds ago ?" Shouldn’t it just grab the frame which is being streamed at the moment ?

    (Sorry for not providing a working code, it’s all over different huge classes)

    I use the following grabber options (selected by some other colleague) :

    grabber.setImageHeight(480);
    
grabber.setImageWidth(640);
    
grabber.setOption("reconnect", "1");
    
grabber.setOption("reconnect_at_eof", "1");
    
grabber.setOption("reconnect_streamed", "1");
    
grabber.setOption("reconnect_delay_max", "2");
    
grabber.setOption("preset", "veryfast");
    
grabber.setOption("probesize", "192");
    
grabber.setOption("tune", "zerolatency");
    
grabber.setFrameRate(30.0);
    
grabber.setOption("buffer_size", "" + this.bufferSize);
    
grabber.setOption("max_delay", "500000");
    
grabber.setOption("stimeout", String.valueOf(6000000));
    
grabber.setOption("loglevel", "quiet");
    
grabber.start();

    Thanks
