  • Multilang : améliorer l’interface pour les blocs multilingues

    18 février 2011, par

    Multilang est un plugin supplémentaire qui n’est pas activé par défaut lors de l’initialisation de MediaSPIP.
    Après son activation, une préconfiguration est mise en place automatiquement par MediaSPIP init permettant à la nouvelle fonctionnalité d’être automatiquement opérationnelle. Il n’est donc pas obligatoire de passer par une étape de configuration pour cela.

  • avfilter's anull says "Rematrix is needed between stereo and 0 channels but there is not enough information to do it"

    24 mai 2017, par kuanyui

    I’m trying to write a transcoder according to FFMpeg’s official example with ffmpeg 3.2.4 (official prebuild Win32), and try to transcode a video with stereo audio stream source (from avformat’s dshow).

    In the example code, which passes anull into avfilter_graph_parse_ptr() for audio stream, and "time_base=1/44100:sample_rate=44100:sample_fmt=s16:channels=2:channel_layout=0x3" is passed into avfilter_graph_create_filter(), occurs error in the following avfilter_graph_config() :

    [auto-inserted scaler 0 @ 32f77600] w:iw h:ih flags:'bilinear' interl:0
    
[Parsed_null_0 @ 2e9d79a0] auto-inserting filter 'auto-inserted scaler 0' between the filter 'in' and the filter 'Parsed_null_0'
    
[swscaler @ 3331bfe0] deprecated pixel format used, make sure you did set range correctly

[Parsed_anull_0 @ 330e8820] auto-inserting filter 'auto-inserted resampler 0' between the filter 'in' and the filter 'Parsed_anull_0'
    
[auto-inserted resampler 0 @ 330e8dc0] [SWR @ 3809b620] Rematrix is needed between stereo and 0 channels but there is not enough information to do it
    
[auto-inserted resampler 0 @ 330e8dc0] Failed to configure output pad on auto-inserted resampler 0

    I’ve googled for days but didn’t find any clue for it. Doesn’t what anull do is only "Pass the audio source unchanged to the output", why libav want to resample stereo to 0 channel ? What’s going wrong ?

  • ffmpeg IP camera unable to record

    14 mai 2021, par trycatch22

    I am using an Amcrest POE camera. I have assigned it a static IP which I am able to confirm by logging into it via the browser. Its IP is 192.168.1.200.

    


    I tried following the instructions in this link but couldn't get it to work. I get :

    


    http://admin:admin@192.168.1.200/dd-a End of file


    


    The official ffmpeg documentation does not talk about -segment_time or -segment_format. What is the ffmepg command to grab a stream for a fixed duration and write it to an .mp4 file ?

    


  • FFMPEG capabilities

    11 juillet 2012, par kerim yucel

    I currently have an algorithm which basically processes every preview frames. I have tried to capture the video using MediaRecorder of SDK, however, apparently I can't access the preview frames while MediaRecorder is capturing the video.

    As far as I know, this could be achieved using NDK tools, even though NDK itself does not provide an official API to handle video recording. I know ffmpeg is ported to android and preferred by most of the developers. However, I have just started to develop using NDK and ffmpeg as well.

    I just wonder if ffmpeg supports processing the frames (which already is developed)and most importantly, recording the video.

    Thanks a lot.
