  • av_interleaved_write_frame() : Connection reset by peer mjpeg : What is wrong with mjpeg stream, ffserver and ffplay ?

    31 décembre 2016, par Ilya Yevlampiev

    I’m creating mjpeg stream from image files using ffmpeg and write it to ffserver’s feed :

    sudo ffmpeg -loop 1 -i fon.jpeg -vcodec mjpeg -f mjpeg http://localhost:8090/feed1.ffm

    So, what is wrong in this streaming example, if I have no problem when I substitute streams to the files ?

    I create a mjpeg file using the same parameters 9i.e. file is an output insteadof stream)

    UPD. I have realized, that i fed file1.ffm instead of file.ffm ; that caused some ffserver problem :

  • Ffmpeg concat images doesn't finish all images

    18 septembre 2015, par Simon

    I’m trying to do a simple task with ffmpeg. I’ve pre-generated about 100 png images (all same resolution) and separetely generated a list of them to be used by ffmpeg to concat them into a video. Each frame is likely to be used more than once. The output video is to be about 10,000 frames.

    The problem is that ffmpeg stops at about frame 4000 with no error. The final video works with no error.

    ffmpeg command :

    ffmpeg  -f concat -i frame_list.txt -vf fps=10 output.mov

    frame_list.txt sample :

        file 'frame_0045.png'
    
    file 'frame_0046.png'
    
    file 'frame_0047.png'
    
    file 'frame_0046.png'
    
    file 'frame_0047.png'

  • Problems with frame rate on video conversion using ffmpeg with libx264

    29 mai 2013, par Lars Schroeter

    I have problems with transcoding some videos. I ran the most simple ffmpeg command and it takes very long time and the output file is about 10 times bigger. If I provide the frame rate parameter -r it works well (small file, fast transcoding). What is the problem and how can I solve it ? I don't want to set a fixed frame rate because I guess it's better to leave it the same as source, isn't it ?.

    Maybe the problem is something else, because I found many examples in web where the -r option isn't used. Also transcoding to a different format or with a different source works well without -r option (I tried with ffmpeg 0.7.15 and also 1.2.1). The videos are provided by the users of my website and automatically converted to be suitable for the web. So I need the most general command for automatic conversion.

    In the following ffmpeg output you will find this two suspicious messages :

    • Frame rate very high for a muxer not effciciently supporting it. Please consider specifiying a lower framerate, a different muxer or -vsync 2
    • MB rate (36000000) > level limit (983040)

    The ffmpeg command and output (without -r option) :

        ffmpeg -i '/tmp/standort_aquarium.mp4' -vcodec libx264 output.mp4
