  • Generate video thumbnail using ffmpeg ; Grab from RTMP server

    7 septembre 2011, par Chad Whitaker

    I have research how to generate a video thumbnail user FFMPEG like so :

    ffmpeg -i myfile.flv -vcodec mjpeg -vframes 1 -an -f rawvideo -s 640x480 foo.jpg

    But how can I generate a thumbnail when the file is on another server ? Specifically a RTMP server ? for example : rtmp://foo.rtmphost.com/videos

  • How do I make a video with a static image background in FFMPEG ?

    21 février 2012, par Tim Scollick

    I have an image. I have a transparent FLV. I want to use the image as a background to the transparent FLV and have it outputted as FLV.

    This command works but the video is one frame long :

    ffmpeg -i background.png -f flv -vcodec flv -b 1500k -vf "movie=test_videos/alpha.flv [logo]; [in][logo] overlay=0:0 [out]" -s 800x464 -y output.flv

    I have tried to use the -t and -vframes parameters to no avail.

    Does anyone have any tips ?

  • ffmpeg to transcode streaming video and storage

    8 septembre 2011, par icarus74

    Examples of ffmpeg that I've seen so far all seem to accept a file on disk storage as input, to transcode it into another file in disk storage as output. Also i've come accross ffserver which can be used to stream-out video. However, yet to find a good tutorial or example of ffmpeg used to transcode streaming video/audio, constrained by say parameters like running-time or no. of frames or other event, and save the transcoded media on disk.

    Any pointers, tips or hints would really help.
