I have been having a few issues with ffmpeg. ffmpeg-0.4.8 seemed to work
OK, but some problems seem to have cropped up since the bump to 0.4.8_1.
During "make install", /usr/local/lib/libavcodec.so.0 was symlinked to
/usr/local/lib/libavcodec.so, and vice versa, so no actual lib existed.
A quick vi of patch-libavcodec::Makefile fixed that.
Now, when I capture using a script based on Steve O'Hara-Smith vcr, ffmpeg
dumps core when it finishes:
frame= 375 q=14.0 size= 9446kB time=15.0 bitrate=5158.8kbits/s
ffmpeg in free(): error: page is already free
Abort trap (core dumped)

Lastly, I threw together some C code to set the tuner channel before
firing off ffmpeg, but it seems that ffmpeg resets the channel, even
tho I have not specified BKTR_FREQUENCY. Should this be the case?
Is there any good example code for channel setting, besides digging
thru fxtv source?
Any help would be greatly appreciated.
