2006-12-27pvrusb2: Implement stream claim checking functionMike Isely
From: Pantelis Koukousoulas <pakt223@freemail.gr> Add (and expose) a new function, pvr2_channel_check_stream_no_lock(), in pvrusb2-context.c. This is hopefully the last V4L2 interface related patch to change anything outside pvrusb2-v4l2.c. We need this to implement the open() for the radio device. The reason is that within the *enter_context() section of open() we need to ensure nobody is streaming and if we cannot, we should cleanup after ourselves and return -EBUSY. We cannot just use claim_stream() because 1) That would cause a deadlock trying to re-acquire the context lock 2) We only need to ensure that nobody is streaming. We don't need to actually acquire the stream. Again, this is a kinda ugly patch. Feel free to improve.

2006-03-18Implement mpeg2 garbage filter in pvrusb2Mike Isely
From: Mike Isely <isely@pobox.com> The PVR USB2 hardware seems to like emitting some garbage data before real stream data appears. This problem has been present all along, but with the older 29xxx model series it was benign because the garbage data in question didn't seem to bother mpeg2 players. But with the 24xxx model series, the garbage data includes what looks like a corrupted mpeg2 packet, which kills mythtv and ffmpeg. This fix causes incoming stream data to be discarded until valid mpeg2 data is seen. Signed-off-by: Mike Isely <isely@pobox.com>
2006-03-10Make pvrusb2 aware of alternative hardware typesMike Isely
From: Mike Isely <isely@pobox.com> Notice and track actual hardware type of device. This information is also used now to select the correct FX2 firmware file to load (because they can be different, unfortunately). Signed-off-by: Mike Isely <isely@pobox.com>
