  • Mac App (Cocoa) for producing HTTP Live Streaming

    11 mars 2013, par Michael

    I am building a Mac OS X application (Cocoa) with XCode that captures a video source and outputs the video through HTTP Live Streaming (HLS). After doing a fair amount of research I am thinking that I should be able to use the following stack of elements in my app to make this happen...

    • AVCaptureDevice
    • AVCaptureSession
    • AVCaptureVideoDataOutput
    • FFMPEG
    • mediastreamsegmenter
    • CocoaHTTPServer

    I would really appreciate some feedback as to whether I'm on the right track, or correction if I am mistaken. Obviously any advice, pointers, perhaps some sample code snippets would be so very helpful.

    Many thanks in advance !

  • aacenc_tns : rework TNS descision logic

    17 octobre 2015, par Rostislav Pehlivanov
    aacenc_tns : rework TNS descision logic

    Changes :
    
 - strongly prefer dual filters to a single filter
    
 - less strict about using 2 filters w.r.t. energy
    
 - scrap the usage of threshold and spread, useless
    
 - use odd-shaped windows to set the filter direction
    
 - use 4 bits instead of 3 bits for short windows
    
 - simplify and reduce the main loop to a single level
    
 - add stricter regulations for short windows
    

    All of this now makes the TNS implementation operate
    
as good as it can and it definitely shows. The frequency
    
thresholds are now even better defined by looking at
    
the spectrals and the overall sound has been improved at
    
the price of just a few bits that are well worth it.

  • FFmpeg get a crop without tying it to a specific time period

    30 avril 2021, par Дмитрий Варзанов
    crop = sub.check_output("ffmpeg -i "+file+" -ss 5 -t 30  -vf cropdetect -f null - 2>&1 | awk '/crop/ { print  $NF }' | tail -1", shell=True).decode().strip()


    


    In order not to bind to a time interval, it is possible to analyze the frames for the entire time period of the video file.

    


    It would be a solution if this process was performed quickly, instantly. But unfortunately, it can take hours, depending on the duration of the video

    


    Execute the command to get the duration of the video, and then calculate and set the time to get the crop. We'll have to build forests...

    


    I am looking for a solution in which there will be no need to set the time and at the same time the task will take the least amount of time.

    


    Perhaps someone has a solution ?
