Subject: [PATCH 8/9] DVB: Misc. DVB USB driver updates
Date: Mon, 26 Apr 2004 09:42:19 -0400 [thread overview]
Message-ID: <10829869142261@convergence.de> (raw)
In-Reply-To: <1082986903219@convergence.de>
- [DVB] ttusb-dec:
- Add a parameter to dvb_filter_pes2ts function to specify whether the packet is a payload unit start or not
- Use the hotplug firmware loader for 2.6 kernels instead of compiling the firmware into the module.
- Correct the USB id of the DEC3000-s, add basic support
- [DVB] ttusb-budget:
- Remove spurious discontinuity message when starting streaming
