Ffmpeg python linux image2pipe2/18/2023 ![]() ![]() f rawvideo -pix_fmt argb means accept uncompressed RGB data. Your pipe's Process must start with these arguments: -y -f rawvideo -pix_fmt argb -s 800圆00 -r 25 -i. (Frame_Bytes) //# Send data to FFmpeg for new frame encodeįrame_Bytes.clear() //# empty byte array for re-use with next frameĪnytime you update your bitmap with new pixel information, you can write that as a new frame by sending that bitmap as input parameter to the above function eg makeVideoFrame (my_new_frame_BMP). # Encodes the byte array of a Bitmap object as FFmpeg video frameįrame_Bytes = frame_BMP.getBytes() //# read pixel values to a byte array Example pseudo-code : public function makeVideoFrame ( frame_BMP:Bitmap ) : void Each send will be encoded as a new video frame. You must put your frame data into some Bitmap object and send the bitmap values as byte array. Then aso add incoming input filename as -i - (where by using a blank - this means FFmpeg watches the standardInput connection for incoming raw pixel data. ![]() Normally (in Command or Terminal window) you set input and output as:īut for pipes you must first specify the incoming input's width/height and frame rate etc. The frame data must be uncompressed pixel values (eg: 24bit RGB format) in a byte array that holds enough bytes ( widthx heightx 3) to write a full frame. Yes it's possible to send FFmpeg images by using a pipe. I believe that FFmpeg could receive image from a pipe, does anyone know how this can be done?" "I want to send images as input to FFmpeg.
