Encoding - CPU usage ...
Hi all.
I would really like to use Theora for the commercial product I work on...
It's a Linux based DVR. Actually we use ffmpeg to produce MPeg4 short
clips from 4 BNC channels in CIF resolution.
I made a small module for our project that uses Theora... but I see that
it gets a lot of CPU :(
So I'm here to ask for any kind tips to reduce the CPU usage.
- Hardware... do you think there

v4l
Hi, folks.
Ever since we brought some of our servers up to 6.x, where the gspca
module comes with the kernel, instead of us building it, we've been
seeing problems. One system gives very strange loops - someone walks
through, then repeat a few times, then the next motion, etc. The
current problem is that one camera went out on a different server (it's
6.2, and I'm hoping to bring

libv4l question
Hi all,
Hey I'm trying to do some web cam stuff, and I found this link:
http://freshmeat.net/projects/libv4l/releases/333037
I was doing the "rpm -qa | grep v4l" and nothing comes up,
I did "ls path_to_centos/RPMS/* | grep v4l " and nothing comes up,
I did 'yum provides "*/libv4l*"' and nothing comes up.
Is the CentOS library for v4l named something

Quicktime 2 Theora Transcoder's Nano-Howto
After a bunch of cumbersome testing I was able to transcode a Quicktime
MOV file to OGG with theora and Vorbis. The method's a bit fumbly, but
it works... It is automatable except for the initial audio decoding.
Software used: Xine, oggenc, ffmpeg, ffmpeg2theora, oggzmerge
Step 1: Get the video out of Quicktime
ffmpeg -i infile.mov -b 5000 -f mpeg2video outfile.mpg
Step 2: Get the video

V4L + Theora small app...
Hi all.
I post a small app I made that create 2 clips using a V4L device.
I would like to get every tips you think it's useful...
Some notes:
- I make 2 clips because in our project we create series of clips and
it's important to check that the all the resources ( memory,
descriptors, etc. ) are freed correctly and to reuse all the resources
that can be reused
- the clips are not well

mixed interlaced content and ffmpeg2theora
dv file from minidv camera - interlaced.
small dv created by imported jpeg images - not interlaced.
seems that when I use ffmpeg2theora with deinterlace switch and reduce
size, it works. But when the only reduction I am doing is to width
(720x480 -> 640x480) the encoder ignores the naturally interlaced bit
and uses the last de-interlaced frame.
Since the small bit made from jpegs is a dv

[PATCH 05/28] media/v4l2: remove V4L2-FLAG-MEMORY-NON-CONSISTENT

Could you explain what makes you think it's unused? It's a feature of
the UAPI generally supported by the videobuf2 framework and relied on
by Chromium OS to get any kind of reasonable performance when
accessing V4L2 buffers

suggestions on other packages
Hi all - Since upstream patches the stock 2.6.18 kernel into something
that is not 2.6.18 (for the rest of the world) I am having issues trying

When compiling packages like v4l that a doing conditionals based on
kernel number - but - header files are messing other things up...
is there some great trick to getting

help - Theora/Vorbis/Ogg, ogmmerge and ffmpeg2theora
Hi,
I'm probably being fairly stupid. But I did the following, starting with
the following two files:
# tcprobe -i vts_01.m2v
[tcprobe] MPEG elementary stream (ES)
[tcprobe] summary for vts_01.m2v, (*) = not default, 0 = not detected
import frame size: -g 720x576 [720x576]
aspect ratio: 16:9 (*)
frame rate: -f 25.000 [25.000] frc=3
