  • fate : add scale filters for big-endian architectures.

    14 septembre 2020, par Nicolas George
    fate : add scale filters for big-endian architectures.

    Filters mostly work in native endianness, but they must output
    
a specified endianness, usually little : that requires a final
    
conversion for big endian.
    

    I do not know what's the deal with gif-deal : inserting explicitly
    
the filters that are implicitly inserted result in less frames in
    
output. Probably a strange problem of duration.

  • ffmpeg record audio from Xvfb on Centos

    25 mai 2017, par boygiandi

    I’m trying to record audio from Xvfb. And I have some problems :

    1. What’s the different between alsa and pulse. I get confuse
    2. Server Centos have no soud card :

    arecord -l

    arecord : device_list:268 : no soundcards found...

    1. I may have many Xvfb process, how to record video and audio from specific Xvfb process. I checked this https://trac.ffmpeg.org/wiki/Capture/ALSA#Recordaudiofromanapplication but still don’t understand how it works.

    ffmpeg -f alsa -ac 2 -i hw:0,0 -acodec pcm_s16le output.wav

    I seen many command like this, but I don’t know how to get hw:0,0 ( id of sound card ? )

    Please help. Thanks

  • Converting mkv to h264 FFmpeg

    14 janvier 2021, par Rikus Honey

    EDIT :
This question has become very popular and is one of the top results for searching "convert mkv to h264 ffmpeg" and thus I feel it is appropriate to add that for anyone stumbling upon this question to rather use

    


    ffmpeg -i input.mkv -c:v libx264 -c:a aac output.mp4


    


    as libvo_aacenc has been removed in recent versions of FFmpeg and it now has a native aac encoder. For more information visit the FFmpeg wiki page for encoding AAC.

    


    Here is the original question :

    


    I would like to convert my .mkv files to .mp4 using FFmpeg. I have tried the following code :

    


    ffmpeg -i input.mkv -c:v libx264 -c:a libvo_aacenc output.mp4


    


    But I get the error :

    


    


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

    


    


    Is there any way to get around this ? I have tried setting the bitrate of the audio but the problem seems to persist.
