I'm having problems with an app called streamer. It is a part of xawtv,
and it is supposed to allow for the capture of video and audio streams
through a TV tuner card. I can get video captured and saved just fine,
but I can't get sound. My capture card (Mach-TV) uses the bt878
chipset.
Here is the sequence of commands I use to capture the input from the TV
or VCR...
streamer -t 0:30 -s 704x480 -r 24 -o movie.avi -f mjpeg -F stereo
lav2wav +n movie.avi | mp2enc -o audio.mp2
lav2yuv +n movie.avi | mpeg2enc -o video.m1v
mplex audio.mp2 video.m1v -o movie.mpg
The problem manifests when I run lav2wav. Here is the output I get from
it...
INFO: [lav2wav] Norm set to NTSC
INFO: [mp2enc] Opened WAV file, freq = 44100 Hz, channels = 2, bits =
16
INFO: [mp2enc] format = 0x1, audio length = 2147483392 bytes
INFO: [mp2enc] slots/frame = 731
INFO: [mp2enc] frac SpF=0.429, tot bitrate=224 kbps, s freq=44.1 kHz
INFO: [mp2enc] Fractional number of slots, padding required
INFO: [mp2enc] System is little endian
**ERROR: [lav2wav] rewind failed - wav-header is corrupt
INFO: [mp2enc] Avg slots/frame = inf; b/smp = inf; br = inf kbps
INFO: [mp2enc] Encoding with psychoacoustic model 2 is finished
INFO: [mp2enc] The MPEG encoded output file name is "audio.mp2"
What is causing that error, and how can I fix it? If it is not easily
fixable, what other tools can be used for capturing video and audio
from the TV or VCR?
