  • Les tâches Cron régulières de la ferme

    1er décembre 2010, par

    La gestion de la ferme passe par l’exécution à intervalle régulier de plusieurs tâches répétitives dites Cron.

  • Amazon Alexa Audio Encoding- Few audios are not playing [closed]

    3 mars 2023, par Vijayanath Viswanathan

    I am encoding audio for Alexa audio using ffmpeg like below,

    



    ffmpeg -i  -ac 2 -codec:a libmp3lame -b:a 48k -ar 16000 


    



    The problem is few of the audios are playing properly but few are not. I am using same Project Rate and Quality (Project Rate 16000 and Quality to 48 kbps) for all audios which needs to be converted. Anybody knows is there any basic quality for source.mp3 to encode to Project Rate 16000 and Quality to 48 kbps ?

    



    The response I am getting from alexa for faulty file is, "There is a problem with skill response".

    Quand une personne répond dans le forum en entourant par "code"

    <necessite version="[2.0.0;2.1.99]"></necessite>
    La prévisalisation est ok, par contre après avoir valider le message, cela écris :

  • Recording video in C#

    31 juillet 2014, par pfedotovsky

    I have to do the following : record video from camera using C#. Camera I use produces video frames (framerate is not fixed) and I have to somehow put all the frames together and create video file. Also I need to use different codecs such as AVI or MPEG4 (these codecs are required, others are optional).

    The main problem I faced is how to create video in which framerate is not fixed. I have a stream of frames, for example I can recive the first frame after 1ms, then after 20ms, then 36ms and so on. If I create video with 25 frames/second the result will be wrong because it means that frames are added after 40ms.

    I tried to use Aforge.Video library, it has a method http://www.aforgenet.com/framework/docs/html/84a560df-bfd5-e0d6-2812-f810b56a254d.htm which adds a frame according to timespan. But this method has problems with setting bitrate - the bitrate value I pass to the method simply ignored (http://www.aforgenet.com/forum/viewtopic.php?f=2&t=2665).

    So my questions is : is there some C# library which I can use to video recording ? I have to support AVI and MPEG4, also possibility to set bitrate and the last but not the least - record video with variable framerate.

    Thanks in advance. Any suggestions would be very helpful.

    UPD1 : I can’t connect to camera directly - all I have is a stream of frames and I need to convert this stream to video at run-time.

    UPD2 : A library I’m looking for should satisfy the following properties. It has to contain a method (or some way how to do the same) to add next frame with a timestamp just like in Aforge.Video.FFMPEG :

    public void WriteVideoFrame(Bitmap frame, TimeSpan timestamp)

    And it should be possible to choose different codecs (at least AVI and MPEG4) and also to set bitrate.
    Is there some alternatives to Aforge.Video.FFMPEG ? Because Aforge doesn’t work properly - the bitrate value is ignored, also some codecs are not supported (MPEG2 for example).

    UPD3 : One more questions about codec license. If I use open source library, should I worry about the codec license ?
