This is a 'Sp'ectrum 'An'alyzer Plugin for the Video Disk Recorder (VDR). Requirements: VDR & (lib)fftw3 Description: A plugin that can receive PCM-data from other plugins (e.g. mp3ng) to compute frequency-data and to provide them to other plugins to display a 'Sp'ectrum 'An'alyzer. It is meant as a kind of middleware between these providers and clients to be as generic as needed to be able to implement the visualisation on all kinds of output-devices (OSD, lcd, graphlcd, framebuffer, etc.). Sketch of the architecture: | Data-provider sends PCM-data ---> | SpAn-plugin | >--- Visualization-clients request the spectrum-data "making s.th. handsome out of it" | Installation: cd /put/your/path/here/VDR/PLUGINS/src tar -xzf /put/your/path/here/vdr-span-X.Y.Z.tar.bz2 ln -s span-X.Y.Z span cd /put/your/path/here/VDR make make plugins ./vdr -P span Setup: Activate spectrum analyzer? yes/no De-(Activates) the plugin. yes: The plugin receives data (only if clients also request data) and on request hands the results over to clients. no: In this case all data provider- and visualization-plugins are rejected when trying to hand over data or to request results. Use logarithmic diagram yes/no A (yet naive) try to equalize the heights of the bars a bit. Lower frequencies are prevailing which results in an "high dynamic range of the heights of the bars" (= mostly few extremely high bars on the left, further right more decreasing or even no bars at all). yes: Suspends a "no" at "Use pure (unequalized) data". Scaling of the heights of the bars is done logarithmically. no: No logarithmic scaling is done. Tips to improve this way of equalizing are warmly welcome! Hide mainmenu entry yes/no Should be self-explanatory. At the moment there is no use of displaying the plugin's entry in the main menu. See ToDo (way below) for the reason. Use pure (unequalized) data yes/no yes: Really compute the pure data without equalizing anyhow. no: Values of higher frequencies are emphasized resulting in a "bit nicer way of displaying the frequencies" than with pure data. Notes: - Tested on VDR-1.4.0 with a FF-DVB-s 2MB (CPU = PIII 1,2GHz) with mp3ng-plugin as self-made data provider as well as visualization-client. Additionally the lcdproc-plugin was used as visualization-client, but just as a proof-of-concept. Thus, there were two clients active simultaneously. - I would be very glad if the authors of plugins for rendering vdr-information on (external) displays (graphlcd/graphtft/lcdproc/etc.) or the OSD (mp3(ng)/ cdda/radio?/muggle?) used the data provided by this plugin to visualize a spectrum analyzer. Generic example how to use it: // Please see the "real" README for the "HowTo". TODO: - Test the stuff with cdda-plugin (provider) and graphlcd-plugin (visualization) - Test it on my streaming-client (it's a PIII 450MHz with DXR3 now) - Implement the output of the names of all data-source- and visualization-plugins on selecting the mainmenu's entry. A change in the "Plugin-Service-Protocol" could be neccessary to support getting ALL plugins that can handle a service. - Implement bar-peaks and their fall off |

- die Fehler behoben, die zum "glibc: ..double free or corruption.." führten. Zumindest habe ich die Meldungen nicht mehr bekommen und valgrind beschwert sich nicht mehr über "das Geschreibsel" außerhalb der erlaubten Grenzen. Und bei meinen Tests, bei denen ich wirklich oft den VDR samt span- und mp3ng-Plugin (und lcdproc) neu gestartet habe, gab es keine Abstürze mehr.This post has been edited 1 times, last edit by "theonlychriss" (Sep 1st 2006, 6:27pm)
