  • How to write out a MOV video into a raw, uncompressed format ?

    8 juin 2015, par feroze

    I have a video in a MOV file format, shot using an IPhone. I have to convert it into an uncompressed raw format, with multiple frames laid out one after the other. This has to be written to a file for post processing.

    Is there a stock format out there that I can convert this video to, using ffmpeg ? If not, I will have to write a C program to open the MOV file and write out the video. I have never worked in video land before, so I am confused about the options.

    I took a look at ffmpeg documentation, and did a web search, but all of them are talking about using ffmpeg as a command line tool, and not about how to write out a file format that I want.

  • FFmpeg - Transcode video and keep original EXIF metadata in the transcoded file ?

    10 mai 2015, par Paulo

    I am trying to transcode a video from a .mov (recorded with the iPhone) and add the original metadata to transcoded file, how can I achieve that ?

    Here is what I have tried but it does not add the metadata :

    ffmpeg -i input.mov -map 0 -vcodec libx264 -preset superfast -acodec libfaac output.mp4
    

    
ffmpeg -i input.mov -map_metadata 0  -vcodec libx264 -preset superfast -acodec libfaac output.mp4

    I have also tried to transcode to webm but it also does not have the metadata, what am I doing wrong or how can I achieve that with ffmpeg ?

  • How to get CMSampleBufferRef from AudioQueueBufferRef

    26 novembre 2015, par arturdev

    I am using a private library which was made for live broadcasting from iPhone.
    In every time of recording each frame it call a delegate function

    void MyAQInputCallback(void *inUserData, 
                              AudioQueueRef inQueue,
                              AudioQueueBufferRef inBuffer,
                              const AudioTimeStamp *inStartTime,
                              UInt32 inNumPackets,
                              const AudioStreamPacketDescription *inPacketDesc) ;

    Now how I can append this inBuffer to my AVAssetWriterInput as usual :

    [self.audioWriterInput appendSampleBuffer:sampleBuffer];

    I think maybe convert AudioQueueBufferRef to CMSampleBufferRef somehow ?

    Thank you.
