metadata switches for ffmpeg2theora
Jan,
Here's a hacky patch to add a few commandline options for setting
comment header fields in ffmpeg2theora. It's a bit big because I
virtualized the global info struct in theorautils.c. In retrospect
that probably wasn't necessary, but I think it's cleaner anyway.
I didn't test it because I couldn't compile ffmpeg2theora, but
modulo bugs it should support

Bug(?) in the example encoder (details re: audio from fifo)
I did a little poking about with the pcm-from-fifo problem I
was having...
What I'm attempting to do is an on-the-fly export from one file
using mplayer to generate yuv4mpeg video frames and pcm audio, piped
through fifo's. This DOES work with mpeg2enc/mp2enc, so I'm assuming
it's not a problem with, e.g., my filesystem...
the example encoder appears to successfully open and

Simple encodig sample...
Hi all.
I'm Mat & I'm new :)
I'm testing libtheora + libogg perhaps for a commercial product.
I started watching encoder_example.c ... I simplified it for testing
it easier.
It seems ok to me but I have no experience with theora so I would like
to know if my code is correct.
I tried to debug it with Valgrind and I found 4 possible memory leaks...
but I think they can be

[LLVMdev] does clang and llvm take more time to compile c code
Hi, Ben
gcc version is: 4.7.0
clang version is: 3.2
The command options are:
1) clang
generated object files: clang -O3 -c *.c -o x.o
link: clang *.o -lm -o mpeg2enc
2) gcc
generated object files: gcc -O3 -c *.c -o x.o
link: gcc *.o -lm -o mpeg2enc
Yes, maybe it is the config introduced problems, I build it with enable
debug options.
Thanks!

[LLVMdev] does clang and llvm take more time to compile c code
Hello, all
When I compile mpeg2enc of Mediabench, it seems clang and llvm take longer
time than gcc. I meausre the time as follow:
gcc -O3 8.190s
clang -O3 20.253s
will this means clang and llvm are slower than gcc in compiling c code.

Encoding from fifo's
Hello, I'm new to the list, so if this is an FAQ, please point me to the
relevant docs.
I'm playing with Theora, to see what kind of quality I can expect (I
realise its not for production use yet). I've download the source from
CVS, and got it to build, with the example encoder and player.
While trying to find something to serve as a good source of input, I
decided I'd use a

theora-exp encoder issue
Hi,
I'm switching from the mainstream theora trunk to the exp one and I
encounter a problem with the encoder.
Every video I encode are played like a 'mosaic', I do not know how to
say that. The picture is just a bunch of coloured pixels.
During the encoding process the video stream is defined like that:
File stream.yuv is 320x240 15.00 fps 420 video.
Why 420 ? Why not YUV like for

[PATCH] Fix for YUV4MPEG support in encoder_example
As was briefly discussed on IRC, ffmpeg and mplayer currently output
two somewhat incompatible YUV4MPEG streams. This meant that
encoder_example could take input from mplayer, but not ffmpeg or
movtoy4m (a QuickTime->Y4M tool).
This is a patch that fixes this issue and should allow encoder_example to
take input from either format:

encoder_example input formats
Hi all
I have the raw out put of a video camera in following
format: mjpegb, yuvj422p, 1920x1080, 24.00 fps(r).
I cannot directly convert this raw footage to Theora
due to the YUV4MPEG2 only restriction of the
encoder_example.
Isn't it better to support other raw formats in
encoder_example, such as what I have, mjpegb,
yuvj422p?
I presume even if I convert the mjpegb, yuvj422p to

Theora file size

I was surprised with size of Theora files and thought
of feedback.

Building theora 1.1.1 with mingw-w64-gcc 7.1 and msys
Hello,
I recently attempted to build theora 1.1.1 with mingw-w64-gcc 7.1 and
msys and it fails to build the encoder_example.c example program. There
are multiple declarations of the function 'rint'. The source file
created its own version of the function that rounds AWAY from zero.
MinGW-W64 has its own version of the 'rint' function, which does not
round away from zero.

Additional encoding options for theora
Hey all,
I've been using the example reference encoder that comes with Theora
reference implementation from SVN, but there are very few options to
tweak encoding parameters in contrast to other codecs utilities such as
x264, mpeg2enc, etc. Is there a way to access more advanced encoding
parameters for Theora without having to dig into the source itself and
make my own custom encoder app?
