Suggestions for improving ffmpeg performance?
Debian Enthusiasts,
Does anyone have any suggestions for improving ffmpeg performance. To
make a long story, well, not quite so long, I recently converted my home
desktop box from ArchLinux to Debian. Back when I was running ArchLinux,
and maybe one or two distros before, I started using pyTivo, a python
script that can convert almost any video format into something a TiVo box
can play and stream it to said TiVo box. It uses ffmpeg for the
conversion. Under ArchLinux I could start a transfer and watch the video
on my TiVo as it was being streamed. In most cases it would stream the
video faster than normal playback speed, and would finish transferring it
before one could finish watching it. Judging from the indicator lights on
my network switch while a video was being transferred there was constant
communication between my desktop PC and my TiVo. But, since I've switched
to Debian that performance has gone down the drain. I have ffmpeg
installed from Debian-Multimedia.org. Now, running Debian(Lenny), if I
start a video transfer from my PC to my TiVo I have to wait for quite a
while before I try to start watching it. Sometimes the transfer dies in
mid-transfer. Watching my network switch I see intermittent activity
between my desktop PC and my TiVo with two to three second pauses
in between. ldd shows ffmpeg is using the i686 libc6 libraries. I tried
rebuilding the ffmpeg package from source optimizing it for i686, but that
didn't help. Does anyone have any suggestions I might try to improve
performance?
