If you actually explained WHY you don't want to, or can't, use the mad
plugin, we could give you better pointers.

Hi,
I think what you should do is explain your motivations, it would be easier to understand what you are trying to achieve then. Do you want to write a GStreamer mp3 plugin as a way to teaching yourself about the GStreamer framework? Or do you need to write a full mp3 decoder with your companies copyright? Or something else? If you explain that to us I think we will be better able to suggest a solution.

Ya sure i ll tell you my motive , We need to write mp3 plug-in.As we know that filesrc is there for getting my mp3 input file from Local system and push it to mad plug-in.Here is the decoder part comes.So we planned to replace this mad plug-in with my own plug-in which does as mad does.After all decoder processing done here. we ll be pushing this output to next plug-in through push_pad()(that is alsasink or osssink);.This is what we have in our mind. For that decoder part we planned to use libmad library for decoding functionality. Now suggest me what to do ?

You haven't answered the question.
WHY do you want to write an mp3 decoding plugin which: * uses libmad * but can't be the already available 'mad' plugin Is it because (tick the corresponding box): [ ] you don't understand that mad and libmad are the same thing [ ] you just want to write one as practice [ ] you think you can get around legal issues by writing your own [ ] you have no clue and you're just asking random questions Edward On Fri, 2008-11-21 at 19:43 +0530, Gnanasekar wrote: > > Ya sure i ll tell you my motive , > > We need to write mp3 plug-in.As we know that filesrc is there for > getting my mp3 input file from Local system and push it to mad > plug-in.Here is the decoder part comes.So we planned to replace this > mad plug-in with my own plug-in which does as mad does.After all > decoder processing done here. we ll be pushing this output to next > plug-in through push_pad()(that is alsasink or osssink);.This is what > we have in our mind. > > For that decoder part we planned to use libmad library for decoding > functionality. > Now suggest me what to do ? > > Christian Fredrik Kalager Schaller wrote: > > Hi, > > I think what you should do is explain your motivations, it would be > > easier to understand what you are trying to achieve then.

If that's the case then perhaps you can use Google Android's mp3 decoder, which has Apache license, so there are no patent issues. http://android.git.kernel.org/?p=platform/external/opencore.git;a=tree;f=codecs_v2/audio/mp3/dec;h=9b452c101e6b2033c9963768570f6547f3ee5b24;hb=master Maybe there is ARM-specific stuff, so you would need to modify it, but better than starting from scratch! Also, if you are able to compile the OpenMAX IL wrapper too, then you can use it from GStreamer using gst-openmax's element: omx_mp3dec. Lots of possibilities, but you need to explain "why". -- Felipe Contreras ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |

I assume you meant "there are no copyright issues". The apache license does not magically make the patent issues surrounding mp3 go away.

I don't know if it's true or not, but companies seem to think that contributing to GPL code means give away their patents. The Google Android stuff specifically says that wouldn't happen, so I guess there's a patent issue that doesn't happen in their code. -- Felipe Contreras ------------------------------------------------------------------------- This SF.Net email is sponsored by the Moblin Your Move Developer's challenge Build the coolest Linux based applications with Moblin SDK & win great prizes Grand prize is a trip for two to an Open Source event anywhere in the world http://moblin-contest.org/redirect.php?banner_id=100&url=/ _______________________________________________ gstreamer-devel mailing list [hidden email] https://lists.sourceforge.net/lists/listinfo/gstreamer-devel |
