  • How to insert image at the same time as audio over a video using FFmpeg

    7 août 2019, par Mariano Argañaraz

    I have a video, an audio, and an image :
    I would like to overlay the image on the video as the same time as I put the audio over, how would the FFmpeg command be ?
    I’m currently using a command like this to put the audio over video, at a given time.

    ffmpeg -y -i video.mp4 -itsoffset $secondsAt -i audio.mp3 \
    
-filter_complex [0:a][1:a]amix=inputs=2[a] -map 0:v -map [a] \

  • How to encode and segment at the same time ?

    18 octobre 2011, par lvreiny

    I want to implement HTTP streaming server, which is similar to this (http://www.ioncannon.net/programming/452/iphone-http-streaming-with-ffmpeg-and-an-open-source-segmenter/)
    But, instead of segment the video file after it is completely converted by ffmpeg, I want to do encoding and segmenting at the same time (something like if the output stream from the encoder is sent to the segmenter immediately).

    Thanks

  • sws_scale performance comparison to media players real time resize

    14 juillet 2018, par Andrey Katkov

    While playing 4K video user can resize players window - and result image will be scaled smoothly in run time.

    On the other hand - program written with libav which reads 4k video file frame by frame and scale it down with sws_scale function do it less effective : it took more time then video duration to resize it.

    Why is it so ? Maybe because player fps is less and some frames are skipped - but video still looks smooth ?
