  • Error while opening encoder for output stream #0:1 - maybe incorrect parameters such as bit_rate, rate, width or height

    7 janvier 2012, par Rocky Singh

    I am trying to convert an avi video file to flv format via FFMPEG with the following command :

    -i C:\files\input\test.avi -y -ab 448k -ar 48000 -vcodec mpeg4 -s 640x480 -f flv C:\files\output\test.flv

    Here is the response I am getting from ffmpeg :

  • How do I debug why avconv is stalling ?

    9 juillet 2015, par Ecommerce Consultant

    I’m converting .mov files to .mpg files using avconv. The command being run by my php application is as follows :

    avconv -y -i ’$finalvideo’ -target ntsc-dvd -aspect 4:3 ’$mpgvideo’ > $logs

    I’m able to convert small .mov files to .mpg without any problems. However, I’m unable to convert videos that are over ten or fifteen minutes long. The log file is completely empty. When I run the command directly the frame stops somewhere around 34000 no matter which video I pick.

    The cpu shows 97% usage on this process, however, nothing is happening.

    OS Ubuntu 10 

    How can I gather more information about this stalled process ?

    Here’s the frozen output

  • 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
