  • Mac Merge an Audio and Video file together

    13 mars 2014, par user2433617

    So I have a audio and video clip that are the same lengths together and I would like to merge them into one file to make a video clip with sound.

    I found this answer, but it is for iPhone it seems : Merging Audio with Video Objective-C

    Basically, what I want to do is this command from FFMPEG :

    ffmpeg -i TestRecording-20140363110156.mov -i 1393956048.wav -vcodec copy out.mov

    Is this possible ? If not, can I just include the compiled ffmpeg file into my project and call that ?

    Thanks.

  • AR Drone 2.0 video streaming whitout SDK on iOS

    10 janvier 2014, par JosephITA

    I'm coding an app for iOS that interact with the AR Drone 2.0 without using the SDK (poor documentation on the iPhone example).
    At the moment I can send command and receive navdata.
    I have no idea in how to receive video streaming. I know that is an H.264 stream and that I can use ffmpeg, but I'm not sure that this solution will pass the Apple revision.
    Any ideas ?

  • Why frame->pts increases by 20, rather than by 1 ?

    19 mars 2013, par user1914692

    Following the exmaples of ffmpeg : decoding_encoding.c and filtering_video.c, I process one video file taken by iPhone. The video file : .mov, video dimensions ; 480x272, video Codec : H.264/AVC, 30 frames per second, bitrate : 605 kbps.

    I first extract each frame, which is YUV.
    I convert YUV to RGB24, and process the RGB24, then write the RGB24 to a .ppm file. It shows the .ppm file is correct.

    Then I plan to encode processed RGB24 frames to a video file.
    Since MPEG does not support RGB24 picture format, I used AV_CODEC_ID_HUFFYUV.
    But the output video file (showing 18.5 MB) does not play. Movie Player on Ubuntu claims an error : Could not determine type of stream.
    I also tried it on VCL. It simply does not work, without any error information.

    My second questions is :
    For each extracted fram from the input video file, I get its pts as follows according to filtering_video.c :

    frame->pts = av_frame_get_best_effort_timestamp(frame);

    I print out each frame's pts, and find that it increases by 20, like below :

    pFrameRGB_count: 0,  frame->pts: 0
    
pFrameRGB_count: 1,  frame->pts: 20
    
pFrameRGB_count: 2,  frame->pts: 40
    
pFrameRGB_count: 3,  frame->pts: 60

    Where frame is the extracted frame from the input video, and pFrameRGB_count is the count for processed frame in RGB24 form.

    Why are they wrong ?
