Hello, It's been a crazy few days, please forgive my short absence. What have I been doing? Well, rather than spending time discussing a new S2API on the mailing list, I wanted to actually produce a working series of patches that kernel and application developers could begin to test. Here's where all of the new S2API patches will now appear: http://linuxtv.org/hg/~stoth/s2 In addition, here's is a userland application that demonstrates tuning the current DVB-S/T/C and US ATSC modulations types using the new API. (www.steventoth.net/linux/s2/tune-v0.0.1.tgz) A tuning demo app? What? Obviously, tuning older modulation types via the new API isn't a requirements, but it's a useful validation exercise for the new S2API. What _IS_ important is..... that it also demonstrates using the same tuning mechanism to tune DVB-S2 8PSK / NBC-QPSK modulation types, and also has rudimentary ISDB-T support for any developers specifically interested. This S2API tree also contains support for the cx24116 demodulator driver, and the Hauppauge HVR4000 family of S2 products. So those interested testers/developers can modify the tune.c app demo and make changes specific to their area, and try experimenting with the new API if they desire. [1] Obviously, tune.c isn't intelligent, it's not a replacement for szap, tzap or whatever - it's simply a standalone S2API test tool, that demonstrates the important API interface. QAM/ATSC are working well, the HVR4000 changes look fine according to the debug log (although I have no local satellite feed for testing tonight). DVB-T should just work as-is, but I can't test this for a day or so. I.E. I've tested what I can in the US but we might have a few bugs or gotchas! If anyone is willing to pull the tree and begin testing with the tune.c app then please post all feedback on this thread. [2] I've received a lot of good feedback of the original 2007 patches. I expect to start merging those changes of the coming days. Don't be too concerned that your changes are not yet merged, keep watching the S2API tree and they will soon appear ... along with a lot of general code cleanup (checkpatch violations) I expect to catchup on my older email tomorrow. Regards to all, - Steve [1] I'll need to review and diff any of the newer HVR4000 driver derivatives that people have been using, before merging those changes into the S2API tree. [2] Remember you're going to need the cx24116 firmware if you're specifically testing the HVR4000.... but you probably already know that! :) _______________________________________________ linux-dvb mailing list linux-dvb@xxxxxxxxxxx http://www.linuxtv.org/cgi-bin/mailman/listinfo/linux-dvb
