If you send multiple programs, you probably will fill the stream, so you have to reduce quality and/or play games with timing of i-frames and possibly adjusting program start times or commercial break lengths to avoid having multiple programs needing high bitrate at the same time. A detailed explanation of how the fps filter in ffmpeg decides to drop/duplicate frames is given in this post. 264 standard settings and some presets supported Latency control supported; accelerator cards have their own dedicated.

MOV), but this resulted in a couple 'junk' frames at the beginning that made the concatenated video have a stutter where the two clips were joined. FFmpeg contains a set of shared libraries which can be used for different operations: libavcodec: provides a generic encoding/decoding framework and contains multiple decoders and encoders for audio, video and subtitle streams, and several bitstream filters. The FFmpeg solution described above utilizes this model and has N FFmpeg instances. Hi' I'm using a Raspbery Pi and Pi Camera module with OpenCV though the V4L2 driver and have noticed I'm getting sequences of identical frames returned from cv2.

It is the continuation of a project that started in 1998. It created a 44,100 Kbytes video output, much larger than using FFMpeg in command line (also with the default options) or another GUI frontend software for FFmpeg. It is based on FFmpeg's 'maskedmerge' filter, which takes three input streams: a background, an overlay, and a mask (which is used to manipulate the pixels of the overlay layer). 03 Jan 2020 Gyan Doshi.

Negative indexes are relative to the end of the sequence, for example, -1 represents the last image of the sequence. When the frame rate is changed, ffmpeg will drop or duplicate frames as necessary to achieve the targeted output frame rate. In order for the decoders to take advantage of multiple cores, the encoder must set tile-columns and frame-parallel.
