  • Support de tous types de médias

    10 avril 2011

    Contrairement à beaucoup de logiciels et autres plate-formes modernes de partage de documents, MediaSPIP a l’ambition de gérer un maximum de formats de documents différents qu’ils soient de type : images (png, gif, jpg, bmp et autres...) ; audio (MP3, Ogg, Wav et autres...) ; vidéo (Avi, MP4, Ogv, mpg, mov, wmv et autres...) ; contenu textuel, code ou autres (open office, microsoft office (tableur, présentation), web (html, css), LaTeX, Google Earth) (...)

  • Is ffmpeg a good upscaler from SD to HD ? [closed]

    Is ffmpeg a good upscaler to convert SD videos to HD ?

    I use the AVANTI GUI. I installed it and put the ffmpeg and ffplay exe into the folder ffmpeg in the program folder. What I know is that you can only preserve the detail when you upscale from SD to HD. You don’t really gain any additional information. TV companies like Samsung, Sony, LG, Panasonic, Sharp, and others refuse to think so and push the boundaries of upscaling so that additional information can be added when the image is upscaled from SD to HD and HD to 4K and so on and so forth. I’ve run a test through the AVANTI ffmpeg GUI.

    Codec : XVID to H.264
    Bitrate : 1640 kbps to 6000 kbps
    Resolution : 640x480 to 1440x1080
    Format : AVI to M4V
    Audio Codec : AC3 to AAC
    Audio Bitrate : 192 kbps
    Audio Frequency : 48000 Hz
    Upscale method : Spline

    Will this upscale method work in any way with converting SD video to HD video. There’s a lot of SD content out that haven’t made the transition to, or probably never will be, HD.

  • streaming video to c# app

    15 octobre 2014, par Ilya

    I’m writing a streaming app, and I need to show a preview in my app.

    I running ffmpeg process like ffmpeg -rtbufsize 100M -f dshow -i video="Logitech HD Webcam C525" -c:v libx264 -pix_fmt yuv420p  -an -tune zerolatency -preset ultrafast -f tee -map 0:v "[f=flv]rtmp://video.dev/test/test|[f=mpegts]udp://localhost:18234"
    which streams into 2 output : remote rtmp and to local source for preview.

    So, what method I can use to show local preview ?

    I tried this Show a tcp video stream (from FFPLAY / FFMPEG) in an C# application, but ffplay window doesn’t shows, maybe because it creates console window first, and then new window with video.
