Ogg Theora files player for Windows XP

Maciej Mączyński — 2012-05-11T13:07:24

Hello,

Can anyone help me write Ogg Theora files player in Visual C++ 2008?

I built and added to the CLR Empty Project:
- libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/)
- PortAudio_v19_20111121 (http://portaudio.com/archives/pa_stable_v19_20111121.tgz)
- SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip)

What next? First I would like to play the *.ogv file.

I know that in revision 11431 of Theora (http://svn.xiph.org/trunk/theora) there is splayer.c 
(win32\experimental\splayer\), but when I try to compile it Visual C++ shows many errors. 
Besides this in the revision 11431 there aren't all required libraries (for example ogg, vorbis, PortAudio).

Best regards,
Maciej_______________________________________________

Ogg Theora files player

Maciej Mączyński — 2012-04-25T08:37:38

Hello,

I'd like to compile splayer.c from revision 11431 in Visual Studio 2008 on Windows XP. Module splayer.c requires PortAudio. I'm trying to build Portaudio for Windows using Microsoft Visual Studio:
http://portaudio.com/docs/v19-doxydocs/compile_windows.html

I did step 1 and part of step 2.

Step 2 says:
"Copy the entire ASIOSDK2 folder into src\hostapi\asio\."

Where is the src\hostapi\asio\ folder? Should I create it? If so, where exactly?

Point 4 says:
"If you have Visual Studio 2005, Visual C++ 2008 Express Edition or Visual Studio 2010, double click the portaudio.sln file located in build\msvc\."

Where are the portaudio.sln file and the build\msvc\ folder? There aren't these elements in the \theora\win32\experimental\splayer\portaudio\ folder and anywhere else on my hard disk.

Best regards,
Maciej_______________________________________________

It needs significant work to compile on Windows, because it requires a 
completely different audio output backend. There used to be a variant 
for Windows that used PortAudio, but it was removed 6 years ago because 
it was totally unmaintained. You can still retrieve it via svn up 
-r11431 (then look in win32/experimental/splayer). The changeset 
removing it was https://trac.xiph.org/changeset/11432/trunk/theora/win32

Ogg Theora files player

Maciej Mączyński — 2012-04-11T07:04:36

Hello,

I try to compile player_example.c from http://downloads.xiph.org/releases/theora/libtheora-1.1.1.zip in Visual Studio 2008 on Windows XP.
I built and added to the project libogg-1.3.0, libtheora-1.1.1, libvorbis-1.3.2 (http://www.xiph.org/downloads/) and SDL-1.2.15 (http://www.libsdl.org/release/SDL-devel-1.2.15-VC.zip).
When I compile player_example.c Visual Studio shows:

fatal error C1083: Cannot open include file: 'unistd.h': No such file or directory
fatal error C1083: Cannot open include file: 'sys/soundcard.h': No such file or directory
fatal error C1083: Cannot open include file: 'sys/ioctl.h': No such file or directory

I found out that these files are part of Linux, not Windows. Are there equivalents of these files for Windows?
How can I change player_example.c, so that it compile on Windows?

Best regards,
Maciej Mączyński_______________________________________________

Hi Yves :-D,
I don't know what you are using to cross-compile for ARM, but I have had
good results in the past with the commandline tools (gcc, g++, ln, ar, etc)
from codesourcery:

Cheers,
Salsaman.

i used ndk-build here .. don't think i have to set variables manually

ok thanks, will try that.

Re: theora streamer for Android anyone?

Timothy B. Terriberry — 2011-10-15T08:05:05

./configure should work, if you have the appropriate environment 
variables (CC, AS, LD, etc.) set up to point at your Android NDK. 
Personally I've only built them for Android inside Firefox, which uses 
its own build system, and only compiles the decoders (though I've built 
and tested the encoders on more normal ARM Linux systems, where they 
work fine).


Android is a giant PITA, in general, but see 
https://wiki.mozilla.org/Mobile/Fennec/Android for instructions on using 
gdb/gdbserver with it.

Re: theora streamer for Android anyone?

2011-10-15T07:48:54

ok, good to know,
do you have a version compiled for Android?
i mean with all Makefile options ?
maybe my Makefile is wrong...
it's not easy to run gdb on the mobile with dalvik,
all i get is SIGSEGV messages
with raw stack pointers... hum,
not very useful.

Re: theora streamer for Android anyone?

Timothy B. Terriberry — 2011-10-15T06:57:10

libvorbis requires floating point. I'm not aware of a fixed-point 
encoder for Vorbis, however most Android devices these days support at 
least VFP, if not NEON. That said, all of these libraries work just fine 
on ARM. Please be more specific about the kind of crashes you're observing.

theora streamer for Android anyone?

2011-10-15T06:47:47

ola,

i am one of the developers of http://giss.tv,
some people here might know about it.

we use since 5 years some tools
( gstreamer, ffmpeg2theora, pure data, ... )
to make Ogg/Theora/Vorbis
streams related to media-hacktivism
and social movements.

lately, we realized how important it becomes to
have lighter tools in some contexts where you cannot set
a medialab and a decent network,
like in pacific occupation of public spaces
( plaza catalunya, puerta del sol, ... ).

that's why we are trying now to develop
some streaming solutions for mobile phones
and, logically, we try right now to make this work
on Android.

i compiled libogg, libvorbis and libtheora for ARM
and linked it to the Java interface using JNI...
but alas, no luck, it crashes in various places
of the native code, so i guess i need a proper port of the libraries
to Android ( that should work on ARM processors
with fixed point processing no ? ).

i'm writing now this message to know
if anybody have worked on this already
and if they suceeded

Whilst the problem being described is not related to visonair and that
if the software they are trying to develop, I am the creator behind
the visonair project.  I kinda shelved the project as the entire thing
was an experiment (although it failed! It presaged YouTube!) anyway,
the site is still up at http;//visonair.cravecreate.com and directory
at http;//dir.cravecreate.com this will be switching off in November
when my contract with the hosting company ends.

Of you need any help I may be able to shed some light on this problem

Regards

Rob

Great!


We are the producers of Ogg and Theora, but not of Visionair.  Visionair
is developed by a third party (actually, I don't even know what person or
company is responsible for Visionair).


This sounds like a problem with Visionair.  You should consider contacting
them for assistance.

please file a bug with information on the input used and some example
output.

all files or only for some inputs? please file a bug too.

this is due to avisynth support, does it cause problems,
could you file a bug with more information what the issue is.

Better defaults, simpler interface, and a single utility to direct
people to, much as we do currently for ffmpeg2theora in general.

gst2ogg is a great idea, for GNU/Linux systems.  The advantage of
ffmpeg2theora is that it's portable across multiple platforms.

Re: [theora] ffmpeg2theora 0.28 released

2011-08-03T16:48:07

what would be the benefit compared to ffmpeg or a custom build of it,
besides possibly better defaults?

Some time ago I also put together gst2ogg, with a command line interface
like ffmpeg2theora but using GStreamer and supporting more codecs.

Why not write a script that calls ffmpeg2theora or ffmpeg2dirac

Re: [theora] ffmpeg2theora 0.28 released

Basil Mohamed Gohar — 2011-08-02T13:36:22

I think the concept of merging ffmpeg2theora & ffmpeg2dirac is a good
one, but I think some of us should get together and work with j^ and
others to work on the possibility of making a (better name than this)
"any2free" encoding utility which will be optimized for outputting in
free formats such as those supported by and promoted by the Xiph
Foundation, including, for example, VP8/WebM.  This would be a great
boon toward open media, I think.

It would not be easy, and while ffmpeg2theora could be leveraged, I
think it's a lot to ask only j^ to do that, it should be an effort of
more people working together.

Re: [theora] ffmpeg2theora 0.28 released

2011-08-02T13:15:53

in 0.28 get_ffmpeg.sh gets the 0.7 branch of ffmpeg, that only gets
security related fixes.


one issue is that codecs have not the same set of options so even if its
one binary you have to provide other knobs based on the codec.

media.xiph.org y4m rearrangement

Ralph Giles — 2011-05-26T23:01:14

All,

Just to let you know, we've flattened the file hierarchy in Tim's
(derf's) collection of y4m-format test clips. Previously, the HD
content was sorted into separate directories. Now it's all in the same
directory as the SD and CIF-resolution files.

If you have a mirror, you can save yourself some bandwidth by manually
moving everything up a level: 'cd y4m; mv *p/* .' before rsyncing
again.

If you don't have a mirror and would like one, the archive is
available over anonymous rsync:

rsync rsync://media.xiph.org/y4m/  # for a file listing
rsync -a --progress rsync://media.xiph.org/y4m/ y4m/ # for a complete copy

If you're using test scripts which assume the old layout, they will
need updating.

 -r
