Yes, my card's inputs show up as RF, composite, and S-Video respectively. I have composite video coming in just fine. As for audio, I've run a triple RCA cable (red, white, and yellow) from the jacks on the VCR to the corresponding jacks on the bracket attached to my Hauppauge card. It's the same cable I used to hook the VCR to my TV, where it worked fine. The VCR doesn't have S-Video output. Presumably the Hauppauge card has an audio encoder somewhere; I just have to find it.

Your VCR has either mono or stereo RCA audio output jacks, and you can plug them into a stereo RCA-> 1/8" stereo headphone plug or adapter cable to bring it into your sound card. Possibly your video capture card has a separate jack for that? Input 0 is probably RF-frequency NTSC with a tuner to select channels. That's low-quality, but includes audio. Input 2 is S-Video, which is the best of the available video connections if your VCR supports it. (I have one that does... if it still powers up.) -dsr-

Any hints? mplayer is complex application - you need some time to study the documentation for audio you are missing the audio driver, you can try adding -ao alsa:noblock:audiorate=48000:device=duplex or for TV mplayer tv:// -tv driver=v4l2:input=1:norm=NTSC-M:width=720:height=480:forceaudio:immediatemode=0:adevice=/dev/dsp1:amode=1:forcechan=2:audiorate=44100:audioid=1:volume=75 it all depends how the hardware is set these are some ideas I used successfully in the past

The example above is a good starting point. I found that I can watch VHS tapes (or whatever else is plugged into the composite video input) on my machine with the following command: mplayer tv:// -tv driver=v4l2:input=1:norm=NTSC-M:width=720:height=480 Here's what gets written when I tee stdout: MPlayer 1.3.0 (Debian), built with gcc-8 (C) 2000-2016 MPlayer Team Playing tv://.

If I get the parameters wrong (which I did a lot while trying to get the aspect ratio right), my screen and keyboard lock up. The machine is still alive, though; I can ssh in from another machine and send a kill -HUP to mplayer's PID, and it does an orderly shutdown and releases everything. Once I get sound working, the next step is to persuade mencoder to write the video to a file. I tried adding the other parameters you mentioned above, starting with -ovc, but I get the message: Unable to open '/dev/dsp': No such file or directory. It's really upset about this; the message appears three times. And indeed, /dev/dsp doesn't exist.

For example the Hauppauge card would provide a specific max quality of output (the analog to digital converter). Thus here people suggest other hardware. It could be the hauppauge is very low quality. for example when analog TV was still popular I used with gl2 video out driver following. Similar with mencoder except that it goes into a file mplayer -tv driver=v4l2:outfmt=yuy2:width=640:height=480:device=/dev/video0:input=0:forceaudio:immediatemode=0:adevice=/dev/dsp1:amode=1:forcechan=2:audiorate=44100:audioid=1:volume=75:norm=0:normid=0:chanlist=europe-west -vo gl2 -ao alsa:noblock:audiorate=48000:device=duplex tv://

How to capture composite video
I have a number of VHS tapes which I'd like to digitize, and I'm trying to figure out where to start, hardware- and software-wise. I'm running Debian Buster (10.5), kernel 4.19.0-10-amd64. I found a pcHDTV HD-5500, which I believe is basically a Hauppauge WinTV-PVR-150 tweaked for Linux, and dropped it into my box, where it is found by lspci and shows up as /dev/video0. The card has an extender cable which leads to a bracket with RCA connectors for audio and composite video, as well as an S-Video connector. (For now, at least, I'm not interested in the TV tuner on the card.) Presumably, with the proper software and configuration settings, I should be able to plug a VCR into the RCA connectors and have video come up on the computer's screen, and hopefully save it to disk in some sort of standard format.
