Re: [CinCV] Output to DV device via raw1394?

Hi John Don't you have an AGP bus ? or even a PCI.. How do you run cinelerra without one ? Not a criticism at all, don't get me wrong, but how do  you manage that.. try this link http://reviews.cnet.com/graphics-cards/xfx-geforce-7950-gt/4505-8902_7-32455174.html John Detwiler wrote: Because, I don't have a graphics card. I looked at NVIDIA cards but have neither the DC power nor the PCI-Express bus to support them.

I know it is not answering directly your question, but I would not even bother using a camcorder for that.

I'd like to use my camcorder as an interface device, to view Cinelerra's "compositor" output on an NTSC television display. That is, instead of rendering from Cinelerra to foo.dv, and then exporting foo.dv thru, say, Kino to my camcorder, I would like to use the camcorder/television chain as a second 'head' for my workstation. What does work, in my hands: 1. I use the ATrtms hack for raw1394. 2. Kino can capture from my camcorder, and can export back to the camcorder, both via /dev/raw1394 ('for free', without changing any settings). 3. The camcorder can accept DV input over FireWire and display it on my TV via S-video. What I tried with Cinelerra: 1. Opened 'Settings > Preferences > Playback' and set the Video Driver to RAW 1394 and the Device Path to /dev/raw1394 2. Pasted a video asset to the timeline and attempted to play it through the Compositor window. 3. Upon clicking the Play button, Cinelerra crashed with the following console output: ===begin dump=== Device1394Output::open VIDEO1394_TALK_CHANNEL:: Invalid argument signal_entry: got SIGSEGV my pid=9159 execution table size=16: filempeg.C: read_frame: 1167 filempeg.C: read_frame: 1196 filempeg.C: read_frame: 1161 filempeg.C: read_frame: 1167 filempeg.C: read_frame: 1196 filempeg.C: open_file: 164 vrender.C: run: 414 vrender.C: process_buffer: 103 vrender.C: process_buffer: 113 filempeg.C: read_frame: 1161 filempeg.C: read_frame: 1167 filempeg.C: read_frame: 1196 vrender.C: run: 416 vrender.C: run: 427 vrender.C: run: 439 vrender.C: run: 443 signal_entry: lock table size=17 0x92872f0 CWindowTool::input_lock CWindowTool::run 0x8c38c40 BC_Synchronous::next_command BC_Synchronous::run 0x937a730 TransportQue::output_lock PlaybackEngine::run 0x937ad80 MainIndexes::input_lock MainIndexes::run 1 0x93e6540 ResourceThread::draw_lock ResourceThread::run 0x90ce618 BC_WindowBase::event_condition BC_WindowBase::get_event 0x92acd18 BC_WindowBase::event_condition BC_WindowBase::get_event 0x92cc388 BC_WindowBase::event_condition BC_WindowBase::get_event 0x9417098 BC_WindowBase::event_condition BC_WindowBase::get_event 0x937cb68 BC_WindowBase::event_condition BC_WindowBase::get_event 0x91f1520 BC_WindowBase::event_condition BC_WindowBase::get_event 0x94f29f0 OSSThread::input_lock OSSThread::run 1 0x948a158 CICache::total_lock CICache::check_out * 0x8c480c0 AudioDevice::play_lock AudioDevice::run 1 0x945b1d0 RenderEngine::start_lock RenderEngine::start_command 2 0x937b768 Cinelerra CTracking::update_tracker 2 * 0xb7e07ba0 Device1394Output::buffer_lock Device1394Output::run 1 * BC_Signals::dump_buffers: buffer table size=0 BC_Signals::delete_temps: deleting 0 temp files SigHandler::signal_handler total files=0 Aborted ===end dump=== Any thoughts on whether this scheme can be made to work?
