  • Revision eee201c221 : Tile based adaptive mode search in RD loop Make the spatially adaptive mode sea

    Tile based adaptive mode search in RD loop

    Make the spatially adaptive mode search in rate-distortion
    optimization loop inter tile independent. Experiments suggest that
    this does not significantly change the coding staticstics.

  • AIR - Transfer Bitmap data to FFmpeg video

    22 mars 2016, par mika

    Hey I’m running into a similar problem as : Converting RGB to YUV, + ffmpeg

    From AIR, I figured the encoding was too long to render frames at a reasonable rate - so I exported the argb ByteArray from bitmap.getPixels(rect) directly to a file.

    So for a 30sec flash animation, I’d export let’s say 1500 frames to 1500 .argb files.

    This method works great. I was able to render HD video using the ffmpeg cmd :

    ffmpeg -f image2 -pix_fmt argb -vcodec rawvideo -s 640x380 -i frame_%d.argb -r 24 -qscale 1.1 -s 640x380 -i ./music.mp3 -shortest render-high.mpg

    So far so good ! However, inbetween the two processes we need to store those 3gb of data.

    I then tried to append all the argb to one single file and have ffmpeg consume it, but didn’t get anything good out of it... Also tried messing tcp/udp but getting stuck...

    Does anyone know of a way to streamline that process and hopefully pipe both Air and ffmpeg together ?

  • Mix audio input with video to specific location with FFmpeg

    26 septembre 2016, par user2364292

    I created small video editing tool with which you can put some overlay images to the video and show them at specific locations and durations (filter : overlay=enabled(from, to...), etc.).
    Now I also want to add some short audio sounds on the same way like pictures -> adding them to a specific time in the video. That means that overlays and audio sounds should be in one command if possible. I am using amix to merge all sound channels (video.mp4 and sound.mp3) but the thing is that they both start at the beginning. I tried with adelay=1500 but then I actually delay one channel that means I hear duplicate sounds with 1.5 sec delay. So I would like to delay only sound.mp3 input. Am I doing something wrong ?

    My try was that :

    -i video.mp4 -i sound.mp3 -filter_complex amix -preset ultrafast -vcodec libx264 -r 24 -profile:v baseline -threads 14 video_output.mp4

    Thank you very much !
