  • 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.

  • Issue when streaming some TV channels threw ffMpeg

    7 octobre 2016, par Raphael Serievic

    I am trying to stream a TV Tuner feed with ffMpeg through udp.

    The ffMpeg command line I use is the following :

    ffmpeg.exe -i udp://@239.255.255.9:1234 -map 0:p:1317:0 -profile:v baseline -crf 30 -preset ultrafast -vcodec libx264 -r 25 -vf scale=720:576-b:v 500k -f rtp udp://10.150.112.107:15048/ -map 0:p:1317:1 -acodec pcm_mulaw -strict experimental -ar 8k -ac 1 -b:a 128k -f rtp udp://10.150.112.107:15032/

    Where :

    • 1317 is the program id (channel)
    • 10.150.112.107 is where I want to stream the TV channel
    • 239.255.255.9 is where I receive the original TV channel’s feed from my TV Tuner

    My problem is that with some program IDs it is working and with some others it is not : it is working with 1572 ("channel 10 hd") but not with 1317 ("7flix Sydney").

    The output of this command-line for channel 1572 (where it works) is the following :

    C:\Program Files (x86)\Tuner Manager\ServerModule> ffmpeg.exe
    -i udp://@239.255.255.7:1234 -map 0:p:1572:0 -profile:v baseline -crf 30 -prese

  • 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.

  • Processing .Raw images using ffmpeg or OpenCV

    After reading Wikipedia page of Raw image format which is the digital negative of any image.

    To be viewed or printed, the output from a camera's image sensor has
    to be processed, that is, converted to a photographic rendering of the
    scene, and then stored in a standard raster graphics format such as
    JPEG. This processing, whether done in-camera or later in a raw-file
    converter, involves a number of operations, typically including

    I have some .raw files grabbed from my Logitech c920 using v4l2 example but when I display the image it looks like this :
    raw frame file a raw image where in other frames I can see my shadow

    Does anyone knows how to process such files to see the complete frame ?
