  • FFmpeg : avconv and ffserver - connection reset by peer

    5 mars 2016, par einsA

    I’m trying to stream a video via ffserver. My dev environment is a Raspberry Pi 2.

    I’m getting an av_interleaved_write_frame(): Connection reset by peer with the following approach :

    pi@raspberrypi:/opt/livefeed $ avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" http://localhost:8090/feed1.ffm

    So why does it works step by step via the movie.flv file and not directly ?

    What is the difference between

    • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" movie.flv
      followed by
      ffmpeg -stream_loop -1 -i movie.flv http://localhost:8090/feed1.ffm and

    • avconv -f mjpeg -i movie.mjpg -r 20 -b 2000k -vcodec libx264 -preset ultrafast -f flv -metadata streamName="mjpeg_to_flv" -metadata title="converting mjpeg to flv via avconv" http://localhost:8090/feed1.ffm ? Why ends this command with a av_interleaved_write_frame(): Connection reset by peer ?

  • ffmpeg slideshow video from images creating empty mp4

    27 novembre 2017, par greenthumbtack

    I’m trying to use ffmpeg to create an .mp4 from a set of .JPG files. This is the ffmpeg line I’m using :

    ffmpeg -framerate 1/5 -i image-%03d.JPG output.mp4

    and a output.mp4. When I run this file, it ends immediately without showing any images. I don’t see any errors or problems in the code, so I’m not sure what I’m doing wrong. Do I need to increase the video framerate or something else ?

  • Where can I find my output video file after execution of ffmpeg command

    7 août 2019, par Giri Aakula

    I run this command to capture my screen

    ffmpeg -video_size 1366x768 -framerate 60 -f gdigrab -i desktop -c:v libx264 -crf 0 -preset ultrafast output.mp4

    I didn’t find the output.mp4 file anywhere in my HDD. I checked in the bin folder of ffmpeg it is not there.
    I searched the whole PC I didn’t find it anywhere. Can anyone please help me out to find the file.
    The console output is
