I can make all the required ioctl calls without any problems but when I try to read then from /dev/dsp (I make all the config stuff through /dev/mixer) it halts for a few seconds and then errors out with an "Interrupted system call." This is similar to a problem I have with doing a "cat /dev/dsp > audio.file" where it halts for a few seconds and then exits with the same message. Is there something obvious I am doing wrong? I am opening the correct devices, the ioctl calls to setup the rate, resolution, and recording source are all working. I have even tried calling both a RESET and a SYNC as the very first steps in the program after opening both devices but this doesn't help. I am running FreeBSD 2.0.5 and whatever voxware came with that version (Sound Driver:2.90-2 comes back from /dev/sndstat). Thanks for your time. ==================================================================== Frank Ficnar ficnar@ecf.toronto.edu -------------------------------------------------------------------- From owner-freebsd-multimedia Thu Dec 28 08:52:43 1995 Return-Path: owner-multimedia Received: (from root@localhost) by freefall.freebsd.org (8.7.3/8.7.3) id IAA16132 for multimedia-outgoing; Thu, 28 Dec 1995 08:52:43 -0800 (PST) Received: from kitten.mcs.com (Kitten.mcs.com [192.160.127.90]) by freefall.freebsd.org (8.7.3/8.7.3) with SMTP id IAA16121 for ; Thu, 28 Dec 1995 08:52:37 -0800 (PST) Received: from mailbox.mcs.com (Mailbox.mcs.com [192.160.127.87]) by kitten.mcs.com (8.6.10/8.6.9) with SMTP id KAA20210 for ; Thu, 28 Dec 1995 10:52:36 -0600 Received: by mailbox.mcs.com (/\==/\ Smail3.1.28.1 #28.5) id ; Thu, 28 Dec 95 10:52 CST Received: by mars.mcs.com (/\==/\ Smail3.1.28.1 #28.5) id ; Thu, 28 Dec 95 10:52 CST Message-Id: Subject: Scrolling motion video To: freebsd-multimedia@freefall.FreeBSD.org Date: Thu, 28 Dec 1995 10:52:33 -0600 (CST) From: "Lars Jonas Olsson" Cc: jonas@mcs.net X-Mailer: ELM [version 2.4 PL24] Content-Type: text Sender: owner-multimedia@FreeBSD.ORG Precedence: bulk I would like to display an endless 768 pixel high image on a 1024x768 24-32 bpp monitor. The image would be scrolled 25-50 times/s to produce smooth scrolling from right to left of the monitor with new image data coming in at the right side. I assume that this is impossible using standard X windows and that I need svgalib or DGA extension. In svgalib there is a function vga_setdisplaystart() that seems to do the hardware scrlling (like virtual desktop in X servers). Is there something like this in DGA? Where can I find DGA descriptions? Jonas
