Review of Linux Compatibility
The Hauppauge WinTV PVR-250 is a PCI card and perfect for usage under Linux. The card is automatically recognized
by the kernel:
00:0a.0 Multimedia video controller: Internext Compression Inc iTVC16 (CX23416) Video Decoder (rev 01)
and needed drivers are loaded automatically:
ivtv: Start initialization, version 1.4.3 ivtv0: Initializing card 0 ivtv0: Autodetected Hauppauge card (cx23416 based) ivtv0: Unreasonably low latency timer, setting to 64 (was 32) ivtv0: Autodetected Hauppauge WinTV PVR-250 saa7115 1-0021: saa7115 found @ 0x42 (ivtv i2c driver #0) msp3400 1-0040: MSP3415G-B8 found @ 0x80 (ivtv i2c driver #0) ivtv0: Registered device video0 for encoder MPG (4096 kB) ivtv0: Registered device video32 for encoder YUV (2048 kB) ivtv0: Registered device vbi0 for encoder VBI (1024 kB) ivtv0: Registered device video24 for encoder PCM (320 kB) ivtv0: Initialized card: Hauppauge WinTV PVR-250 ivtv: End initialization ivtv-alsa: module loading... ivtv0: Loaded v4l-cx2341x-enc.fw firmware (376836 bytes) ivtv0: Encoder revision: 0x02060039
The card is very good for capturing vhs and easy to use: simply put a cable rca-jack (see example) on audio line-in of the WinTV PVR-250 card and a video cable on composite video-in of the card.
The card has a MPEG2 hardware decoder chipset on board (software encoding uses about 30% of CPU and can cause audio/video sync problems). If the onboard hardware encoder is used the audio is in perfect sync and CPU usage is down to 2% with ffmpeg).
The WinTV PVR-250 is automatically supported by latest linux kernel. Only the firmware file
has to be placed in
After reloading of the modules or a system reboot, the TV card is fully available.
Video capturing can be carried out by the following command. First change input to composite:
v4l2-ctl -i 5
The video stream can than be recorded to an mpeg2 file via
ffmpeg -i /dev/video0 -c:v copy -c:a copy output.mpg
The following kernel modules are used by the WinTV PVR-250:
