    I imported ffmpeglib as a module in my project. This is the code is use to compress :

    public class MainActivity extends Activity {
    

    
    private ArrayList&lt;Object&gt; listVideoPaths = new ArrayList&lt;&gt;();<br />

  • Creating a video using ffmpeg in a PHP script

    30 décembre 2017, par Femzy

    I have been trying to solve this problem for a while now, but i have not got it through please someone should help me..
    My main objective is to collect user’n inputs and convert it to a video with black background, then the input text will be moving from left to right while the video is playing with audio in the background. Currently i was suggested to use "drawtext" but i have not find it working
    This is the code I use just to test the drawtext but the thing is, if i try it 10 times it will create a video file ones in many times i tried and even the video file would have 0 kb in size
    The Below code is my code

    The Below is the Report i got from the not working ffmpeg cmmand

    echo shell_exec('ffmpeg -f lavfi -i testsrc=duration=5:size=800x600:rate=30 -vf drawtext="fontfile=/usr/share/fonts/truetype/dejavu/DejaVuSerif-Bold.ttf:textfile=text.txt: x=(w-tw)/2: y=h-(2*lh): fontcolor=white: box=1: boxcolor=0x00000000@1" -preset ultrafast outex.mp4');

  • Transcoded video stream unplayable in QuickTime player

    30 novembre 2017, par Nikolai Linetskiy

    Currently I’m writing software for transcoding media files using ffmpeg libs. The problem is that in case of H264 QuickTime cannot play result stream and shows black screen. Audio streams work as expected. I have read that QuickTime can deal only with yuv420p pixel format and that is true for encoded video.

    I looked through the ffmpeg examples and ffmpeg source code and could not find anything find any clues where the problem might be. I would really appreciate any help.

    The only thing I managed to get from QuickTime is
    SeqAndPicParamSetFromCFDictionaryRef, bad config record message in console. Same thing is logged by AVPlayer from AVFoundation.

    Here is the initialization of output streams and encoders.
