The recorder should use the Linux IR system to record the data. It would confusing to mix the systems. Users need to be really sure that the standard protocol decoders don't understand their protocol before resorting to this. Any one in this situation should post their recorded data so we can check for driver implementation errors. An example: if you use irrecord on Sony remotes lirc always records them in raw mode. The true problem here is that irrecord doesn't understand that Sony remotes mix different flavors of the Sony protocol on a single remote. This leads you to think that the Sony protocol engine is broken when it really isn't. It's the irrecord tool that is broken. The kernel IR system will decode these remotes correctly without resorting to raw mode. > There are some good reasons for that, as it would allow in-kernel support for > protocols that may have some patent restrictions on a few countries that allow > patents on software. Are there any IR protocols less than 20 (or 17) years old? If they are older than that the patents have expired. I expect IR use to decline in the future, it will be replaced with RF4CE radio remotes. > > We'll need to discuss the API requirements for such decoder, in order to load > the RC decoding code into it. > > Cheers, > Mauro. > -- Jon Smirl jonsmirl@xxxxxxxxx -- To unsubscribe from this list: send the line "unsubscribe linux-media" in the body of a message to majordomo@xxxxxxxxxxxxxxx More majordomo info at http://vger.kernel.org/majordomo-info.html
