  • Unable to 'make' android ndk project - build fails : [build-openh264-x86] Error 2

    18 décembre 2015, par NoobNinja

    I’ve attempted these two fixes I’ve found while researching the issue :

    android update project  --23 --/Users/ajswann/Downloads/android-sdk-macosx 
    

    
make OS=android NDKROOT=/Users/ajswann/Downloads/android-sdk-macosx TARGET=android-19 ARCH=x86 clean

    ...however neither seems to resolve the issue.

    Any input/suggestions are appreciated.

    P.S.

    I’m running OSX - could this be an issue with attempting to run an x86 architecture on a 64 bit machine ?

  • HEVC with alpha [closed]

    3 mai 2024, par foxhable

    I trying create HEVC with alpha video from png images through ffmpeg.

    


    When i try, it outputs a video that works, has a transparent background and opens in QuickTime, but does not open in Safari. Then i try creating in prores 4444 codec and convert from macOS Context Menu -> Encode Selected Video Files with HEVC 1080p and Preserve Transparency. It has work - video with transparent background, open in QuickTime and in Safari.

    


    So i tried understand what a difference in meta data and only what i find its working video has HVEC encoder, but not working has Lavc61.5.103 hevc_videotoolbox. Can i somehow programmatically or from utilities like ffmpeg create video with HEVC With alpha, which working like from macOS context menu ? macOS context menu doesnt fit because i cant compress or create many videos

    I have example of working video. Info from ffprobe

  • How to transcribe the recording for speech recognization

    29 mai 2021, par DLim

    After downloading and uploading files related to the mozilla deeepspeech, I started using google colab. I am using mozilla/deepspeech for speech recognization. The code shown below is for recording my audio. After recording the audio, I want to use a function/method to transcribe the recording into text. Everything compiles, but the text does not come out correctly. Any thoughts in my code ?
