Hi, my name is Feld.
Problem: Cannot keep settings for capture device
I am using version 0.8.5 of VLC with the wxWindows interface. The computer/OS is an Athlon 64 running Windows XP Home. The capture device is a CompUSA "High Speed USB Video Grabber" which according to the drivers and to VLC is a "USB 2820 device".
My problem is that the capture device appears to output in a strange aspect ratio. (The software that came with the device, ULead Video Studio 7 SE Basic, appears to be capturing from the device in a 950x480 aspect.)
I have found how to get normal-aspect video to play on the screen:
- File->Open Capture Device
- I get the Open dialog, on the DirectShow tab.
- Press the Refresh list button across from Video device name
- In a few moments, "USB 2820 Device" appears.
- Select USB 2820 Device
- Press Advanced options button
- Get Advanced options (DirectShow input) dialog
- Check Device properties checkbox
- Click OK on Advanced options (DirectShow input) dialog
- Click OK on Open dialog
- Get Properties dialog with tabs Video Decoder, Video Proc Amp, and Video Image tabs. On Video Decoder tab:
- Video Standard is set to "NTSC_M"
- Signal Detected is 1
- Lines detected is 525
- VCR Input is unchecked.
- Get Properties dialog with tabs Video Decoder, Video Proc Amp, and Video Image tabs. On Video Decoder tab:
- Click OK on Properties dialog with Video Decoder, Video Proc Amp, and Video Image tabs.
- Get Properties dialog with single Stream Format tab. Panes are Video Format and Compression; on Video Format pane:
- Video Standard is set to "NTSC_M" (unchangable here)
- Frame Rate is "30.000"
- Flip Horizontal is greyed out
- Color Space / Compression is set to I420
- Output Size says the default is "640x480" but is always "352x240" when this dialog first appears.
- Get Properties dialog with single Stream Format tab. Panes are Video Format and Compression; on Video Format pane:
- Click Apply and OK
- Get Properties dialog with single Crossbar tab. Panes are Input and Output.
- Click OK.
- Video from capture device now appears on screen in a normal aspect ratio.
This works to get video onto the screen, but I would like to use VLC to save the video I'm capturing to file. I can't seem to do this, because if I try to set up a transcoding chain with the input from the capture device, I have no way of changing the Output Size to the 640x480 it should be.
