FXTV is a BSD application that provides TV-in-a-window and image/audio/video capture capabilities for Brooktree-based tuner/capture cards. http://people.freebsd.org/~rhh/fxtv/ Most users have a powerful enough CPU to bypass FXTV and perform a video capture using ffmpeg. My computer is not very powerful. After quite a few experiments, I found that in the best case with my computer I can create an AVI file with no more that 12 frames per second. It is well known that the video capture code for FXTV is awkward, broken, and requires a separate installation of sox, mpeg_musicin, mpeg_encode, and mplex. However, the advantage of the FXTV video capture is that it dumps the raw AV to a (huge) file and performs no real-time processing. The processing is performed when the script generated by fxtv calls the script fxtv_cnvt.sh. To perform the video capture with no processing choose the "MPEG Ready" pull-down option for the "Target" in FXTV. Unfortunately, the script fxtv_cnvt.sh in the FXTV port is broken. The patch file for fxtv_cnvt.sh appended below is a really ugly hack, but it works for me. No changes were required to FXTV, sox, mpeg_musicin, mpeg_encode, or mplex. The output is an *.mps (MPEG System Stream) file. Wikipedia does not have an entry for the MPS file extension, but mplayer will play these just fine on my Fedora 7 computer. This hack is similar to one proposed for OpenBSD: http://www.mail-archive.com/ports@openbsd.org/msg07601.html JM Rotenberry --- /usr/local/lib/X11/fxtv/fxtv_cnvt.sh.orig Mon Feb 18 13:05:40 2008 +++ /usr/local/lib/X11/fxtv/fxtv_cnvt.sh Mon Mar 3 14:18:25 2008 @@ -181,8 +181,8 @@ # Do we need an intermediate file? if [ $mpeg_enc =3D YES ]; then - out_soxfn=3D"$out_fnbase.aiff" - out_soxfmt=3D"AIFF" + out_soxfn=3D"$out_fnbase.wav" + out_soxfmt=3D"WAV" else out_soxfn=3D"$GAout_fn" out_soxfmt=3D"$out_fmt"
