  • AndroidBitmap_lockPixels always failing

    25 avril 2013, par user1568549

    In my jni module I copy images to bitmaps, which were previously
    passed from my java application.

    I do this using AndroidBitmap_lockPixels/AndroidBitmap_unlockPixels.
    Basically, it renders the image correctly, but there're strange
    effects : sometimes the application gets stuck, or after some time
    AndroidBitmap_lockPixels always returns -3

    (ANDROID_BITMAP_RESULT_ALLOCATION_FAILED). I guess this is because I
    update these bitmaps not from the GUI thread, isn't it ?

    If so, what would be correct way to "post" this operation to the GUI

    thread ? Is it possible in jni ?

    Thanks.

  • How do I use ffmpeg with Python by passing File Objects (instead of locations to files on disk)

    1er mai 2012, par Lyle Pratt

    I'm trying to use ffmpeg with Python's subprocess module to convert some audio files. I grab the audio files from a URL and would like to just be able to pass the Python File Objects to ffmpeg, instead of first saving them to disk. It would also be very nice if I could just get back a file stream instead of having ffmpeg save the output to a file.

    For reference, this is what I'm doing now :

    tmp = "/dev/shm"
    
audio_wav_file = requests.get(audio_url)
    
##              ##                         ##
    
## This is what I don't want to have to do ##
    
wavfile = open(tmp+filename, 'wrb')   
    
wavfile.write(audio_wav_file.content)
    
wavfile.close()
    
##              ##                         ##
    
conversion = subprocess.Popen('ffmpeg -i "'+tmp+filename+'" -y "'+tmp+filename_noext+'.flac" 2>&1', shell = True, stdout = subprocess.PIPE).stdout.read()

    Does anyone know how to do this ?

    Thanks !
