  • Can x264 be used from Java code via JNI to decrease the resolution of RTMP streams ? [on hold]

    5 septembre 2016, par Orr151

    I would like to implement a custom RTMP transcoder to HLS format in Java. As the repackaging itself seems to be relatively clear and doable in Java, then I found the modification of the video resolution a bit challenging in Java. My plan is to avoid using existing solutions like FFmpeg or at least minimize the amount of 3rd party frameworks/tools integrated with my component.

    After some research it seems that reusage of JCodec and Xuggler can be challenging as both project are idle for a while. Also I’m not sure if their performance is acceptable. That’s why I would like to integrate directly with x264 library via JNI from Java code.

    Is integration with x264/libx264 from Java code to decrease resolution/bitrate doable and is it a good idea ? Could you please suggest any other solutions ?

    Thanks !

  • Fast method for adding text watermark to only first 25 frames using ffmpeg

    4 février 2023, par Sarkar

    I am looking to add a text watermark to the first 25 frames of a video using ffmpeg. I have already tried the following command but it takes a long time as it processes the entire video :

    


    ffmpeg -i input.mp4 -vf "drawtext=fontfile=arial.ttf: text='Watermark': fontsize=24: fontcolor=white: x=(w-text_w)/2: y=(h-text_h)/2: enable='between(n,0,24)'" -c:a copy output.mp4


    


    I need the encoding to be fast as I plan to make this change on the fly when streaming the video to the user. Is there a way to do this efficiently, such that the rest of the video remains unedited ?
