  • encode x264(libx264) raw yuv frame data

    26 juin 2015, par Mohamed El-Sayed

    I am trying to encode an MP4 video using raw YUV frames data, but I am not sure how can I fill the plane data (preferably without using other libraries like ffmpeg)

    The frame data is already encoded in I420, and does not need conversion.

    Here is what I am trying to do :

    const char *frameData = /* Raw frame data */;
    

    
x264_t *encoder = x264_encoder_open(&param);
    
x264_picture_t imgInput, imgOutput;
    
x264_picture_alloc(&imgInput, X264_CSP_I420, width, height);
    

    
// how can I fill the struct data of imgInput
    

    
x264_nal_t *nals;
    
int i_nals;
    
int frameSize = x264_encoder_encode(encoder, &nals, &i_nals, &imgInput, &imgOutput);

    The equivalent command line that I have found is :

     x264 --output video.mp4 --fps 15 --input-res 1280x800 imgdata_01.raw

    But I could not figure out how the app does it.

    Thanks.

  • using ffmpeg/ffprobe to create a waveform json using php

    7 mars 2015, par edwardsmarkf

    I have many ogg & opus files on my server and need to generate json-waveform numeric arrays on an as-needed basis (example below).

    recently i discovered the node based waveform-util which uses ffmpeg/ffprobe for rendering a JSON waveform and it works perfectly. i am undecided if having a node process constantly running is the optimum solution to my issue.

    since ffmpeg seems to be able to handle anything i can throw at it, i wish to stick with an ffmpeg solution.

    i have three questions :

    1) is there a php equivalent ? i have found a couple that generate PNG images but not one that generates JSON-waveform numeric arrays

    2) are there any significant advantages of going with the node-based solution rather than a php based solution (assuming there is a php based solution) ?

    3) is there a way using CLI ffmpeg/ffprobe to generate a json-waveform ? i saw all the -show_ options (-show_data, -show_streams, -show_frames) but nothing looked like it produced what i am looking for.

    the json-waveform needs to be in this format :

    [ 0.0002, 0.001, 0.15, 0.14, 0.356 .... ]

    thank you all.
