  • Support audio et vidéo HTML5

    10 avril 2011

    MediaSPIP utilise les balises HTML5 video et audio pour la lecture de documents multimedia en profitant des dernières innovations du W3C supportées par les navigateurs modernes.
    Pour les navigateurs plus anciens, le lecteur flash Flowplayer est utilisé.
    Le lecteur HTML5 utilisé a été spécifiquement créé pour MediaSPIP : il est complètement modifiable graphiquement pour correspondre à un thème choisi.

    Modules spécifiques
    Pour la configuration d’Apache, il est conseillé d’activer certains modules non spécifiques à MediaSPIP, mais permettant d’améliorer les performances : mod_deflate et mod_headers pour compresser automatiquement via Apache les pages. Cf ce tutoriel ; mode_expires pour gérer correctement l’expiration des hits. Cf ce tutoriel ;
    Il est également conseillé d’ajouter la prise en charge par apache du mime-type pour les fichiers WebM comme indiqué dans ce tutoriel.

  • ffmpeg blend to exclude the top videos background

    2 février 2016, par user2995705

    I want to blend two videos, the top video named "top.mp4" was combined with some PNG files,but the combined video’s background was black ? why ?

    then i try to overlay the top.mp4 on another video (named bottom.mp4,was capture by android camera with QUALITY_480P)

    but when I use Overlay filter i find the top.mp4 was not transparent and have a black background on the result.mp4.

    I try to use blend filter to combine top.mp4 and bottom.mp4 to exclude the top.mp4’s black background , but i don’t know how to use the blend filter.

    here is my question :
    1.is it possible to combine PNG files to a video and the video has transparent background ? and then just use overlay filter,the result.mp4 will not have a black mask under the top.mp4 ?

    2.if 1 is impossible, how to blend top.mp4 and bottom.mp4 to exclude the black background of top.mp4

    my all output log

    25 janvier 2013, par rastapopoulos@… — Log

    On refait les critères dans l’inclusion des graphiques, mais on n’affiche cette inclusion que s’il n’y a pas un trop grand nombre de points ! (là 2000 en dur, complètement au hasard).
    En vrai il faudrait surtout que les graphiques ne s’affichent qu’avec une pagination mois par mois, un truc dans ce genre !

  • Revisiting Nosefart and Discovering GME

    30 mai 2011, par Multimedia Mike — Game Hacking

    I found the following screenshot buried deep in an old directory structure of mine :



    I tried to recall how this screenshot came to exist. Had I actually created a functional KDE frontend to Nosefart yet neglected to release it ? I think it’s more likely that I used some designer tool (possibly KDevelop) to prototype a frontend. This would have been sometime in 2000.

    However, this screenshot prompted me to revisit Nosefart.

    Nosefart Background
    Nosefart is a program that can play Nintendo Sound Format (NSF) files. NSF files are files containing components that were surgically separated from Nintendo Entertainment System (NES) ROM dumps. These components contain the music playback engines for various games. An NSF player is a stripped down emulation system that can simulate the NES6502 CPU along with the custom hardware (2 square waves, 1 triangle wave, 1 noise generator, and 1 limited digital channel).

    Nosefart was written by Matt Conte and eventually imported into a Sourceforge project, though it has not seen any development since then. The distribution contains standalone command line players for Linux and DOS, a GTK frontend for the Linux command line version, and plugins for Winamp, XMMS, and CL-Amp.

    The Sourceforge project page notes that Nosefart is also part of XBMC. Let the record show that Nosefart is also incorporated into xine (I did that in 2002, I think).

    Upgrading the API
    When I tried running the command line version of Nosefart under Linux, I hit hard against the legacy audio API : OSS. Remember that ?

    In fairly short order, I was able to upgrade the CL program to use PulseAudio. The program is not especially sophisticated. It’s a single-threaded affair which checks for a keypress, processes an audio frame, and sends the frame out to the OSS file interface. All that was needed was to rewrite open_hardware() and close_hardware() for PA and then replace the write statement in play(). The only quirk that stood out is that including <pulse/pulseaudio.h> is insufficient for programming PA’s simple API. <pulse/simple.h> must be included separately.

    For extra credit, I adapted the program to ALSA. The program uses the most simplistic audio output API possible — just keep filling a buffer and sending it out to the DAC.

    Discovering GME
    I’m not sure what to do with the the program now since, during my research to attempt to bring Nosefart up to date, I became aware of a software library named Game Music Emu, or GME. It’s a pure C++ library that can essentially play any classic video game format you can possible name. Wow. A lot can happen in 10 years when you’re not paying attention.

    It’s such a well-written library that I didn’t need any tutorial or documentation to come up to speed. Just a quick read of the main gme.h header library enabled me in short order to whip up a quick C program that could play NSF and SPC files. Path of least resistance : Client program asks library to open a hardcoded file, synthesize 10 seconds of audio, and dump it into a file ; ask the FLAC command line program to transcode raw data to .flac file ; use ffplay to verify the results.

    I might develop some other uses for this library.
