  • How to stop ffmpeg automatically rotating (Iphone 13) videos

    22 juillet 2022, par VdGR

    I have a bunch of videos I want to merge into one video.
Therefore I used this ffmpeg command.

    


    ffmpeg -y -loglevel warning -f concat -safe 0  -i "filelist.txt" -c copy "merged.mov"


    


    When I open merged.mov all my videos are rotated -90 degerees but when I open my videos for example in vlc it has the right rotation.
What am I doing wrong ?

    


    I tried already adding the "-noautorotate" option but that does not seem to solve the problem.

    


  • Conversion from Iphone Core Surface RGB Frame into ffmepg AVFarme

    10 mars 2015, par Raghu

    I am trying to convert Core Surface RGB frame buffer(Iphone) to ffmpeg Avfarme to encode into a movie file. But I am not getting the correct video output (video showing colors dazzling not the correct picture)

    I guess there is something wrong with converting from core surface frame buffer into AVFrame.

    Here is my code :

    Surface *surface = [[Surface alloc]initWithCoreSurfaceBuffer:coreSurfaceBuffer];
    
[surface lock];
    
unsigned int height = surface.height;
    
unsigned int width = surface.width;
    
unsigned int alignmentedBytesPerRow = (width * 4);
    
if (!readblePixels) {
    
    readblePixels = CGBitmapAllocateData(alignmentedBytesPerRow * height);
    
    NSLog(@"alloced readablepixels");
    
}
    
unsigned int bytesPerRow = surface.bytesPerRow;
    
void *pixels = surface.baseAddress;
    
for (unsigned int j = 0; j < height; j++) {
    
    memcpy(readblePixels + alignmentedBytesPerRow * j, pixels + bytesPerRow * j, bytesPerRow);
    
}
    

    
pFrameRGB->data[0] = readblePixels; // I guess here is what I am doing wrong.
    
pFrameRGB->data[1] = NULL;
    
pFrameRGB->data[2] = NULL;
    
pFrameRGB->data[3] = NULL;
    

    
pFrameRGB->linesize[0] = pCodecCtx->width;
    
pFrameRGB->linesize[1] = 0;
    
pFrameRGB->linesize[2] = 0;
    
pFrameRGB->linesize[3] = 0;
    

    

    
sws_scale (img_convert_ctx, pFrameRGB->data, pFrameRGB->linesize,
    
       0, pCodecCtx->height,
    
       pFrameYUV->data, pFrameYUV->linesize);  

    Please help me out.

    Thanks,

    Raghu
