Hi all, I've got a real need to use OpenQuicktime (or something similar) to decode individual frames from a Quicktime source. I'd like to use a PNG codec ... Other messages on the devel and users mailing lists indicate that OpenQuicktime is at a point further than the current CVS download. Is it? I will happily hack together a PNG decoder ... but if someone already has working code - I'd rather not. So where is OpenQuicktime at? Has anyone got the necessaries to do this? (Encoding would be nice aswell but not essential). Nige. -- URL: http://www.pixexcel.co.uk |

My understanding of it is basically, yes you can :) BUT keep the library as a separate binary, rather than merging it into=20= your executable (not 100% necessary) And you need to provide the sources to the specific version of the=20 library you use (of course, if you just provide a compiled version of=20 the standard distribution, then you can just point to the main oqt=20 site :) ) And we'd like some gratuitous advertising, but thats purely up to you :) -- ...Silence Please...

Hi, Just read completly the LGPL text (http://www.gnu.org/copyleft/lesser.html), but basically, yes you can create a shareware linking to the library if you respect the rules that are in the licence ... ;) Yann. ----- Original Message ----- From: "Nicholas Humfrey" <nj...@ec...> To: <ope...@li...> Sent: Saturday, January 19, 2002 7:17 PM Subject: [Openquicktime-devel] License > > Hi, > > Can someone just clarify for me the rules of the GNU Lesser License. > > Is it OK to link to OpenQuickTime in a Commercial (well shareware) > closed source product ? > > Can you include a compiled version OpenQuickTime (providing any > changes are publicly available) as part of the product ? > > > My plan is to make a Shareware Macintosh GUI for my streaming project > to make a bit of money. > > Don't worry, it will have no more functionality than the Open Source > command line version I am making but it will be easy to use/install > for Mac users... > > > > Thanks > > > nick. > > _______________________________________________ > Openquicktime-devel mailing list > Ope...@li... > https://lists.sourceforge.net/lists/listinfo/openquicktime-devel > |

Hi, Can someone just clarify for me the rules of the GNU Lesser License. Is it OK to link to OpenQuickTime in a Commercial (well shareware) closed source product ? Can you include a compiled version OpenQuickTime (providing any changes are publicly available) as part of the product ? My plan is to make a Shareware Macintosh GUI for my streaming project to make a bit of money. Don't worry, it will have no more functionality than the Open Source command line version I am making but it will be easy to use/install for Mac users... Thanks nick. |

But basically, I agree, we need to create a thread retrieving the data and do all the oqt calls in another and we should have a mechanism to wait for the data if quicktime_read ask for data not already local ... I wonder if some libraries are not already here that could do this for us ...

I think we should clearly begin with ftp/http, and then pass to RTP/RTSP, so yes, don't hesitate to put this files and others into the CVS ... ;) Yann. |

Needs some buffering mechanism I am not sure how to implement (maybee we'd need a separate thread to get data from the network). Nothing to do with neater protocols, such as RTP/RTSP, just plain HTTP/FTP. However, there are some intersting options in the FTP and HTTP protocols allowing to ask only a byte-range of a file; that could mean seeking is possible. We still need buffering, and a file that has data organized in a stream-like fashion (ie, not a 30 Mb video track followed by a 2 Mb audio track). Tell me if you're interested in this FTP/HTTP video playing, or if we shouldn't bother about this and concentrate on RTP/RTSP! - Antoine |

Hi,
I'm currently playing with the last CVS version of OQT and I've seen some
references to missing functions in comments :
quicktime_read_uristream
quicktime_write_uristream
quicktime_fseek_uristream
quicktime_close_uristream
These functions seems to be in a uristream=2Ec file which is not in the CVS=
=2E
Any chance that its author (Jean-Fran=E7ois ?) put it in the CVS ???
I can't wait trying to read streams from the network ;)

Here's a diff which allows the current CVS snapshot to compile without
warnings on IRIX/MIPSpro. Most of the changes are trivial:
- unused local variables
- nested comments
- broken printf specifications
Exceptions are:
plugin.c
quicktime_delete_external_vcodec()
quicktime_delete_external_acodec()
Both of these non-void functions fail to return anything, even though
their return value is used. Added a FIXME comment.
Also, since that code comes from somewhere else, I didn't touch lame
or mpg123. Hope this is useful. BTW, the fix to the configure script
seems to work, it now runs fine under IRIX.
Hope this is a bit useful,
JF

(The main problem is that the configure script should be designed to work on _any_ platforms, but I could only try it with gcc on i386 Linux/FreeBSD, sparc Solaris, and with Sun's cc on Solaris, not on IRIX...) A -fpic alike flag does not seem needed with MIPSpro, I assume the -shared link flag is sufficent to make shared libraries. I have updated the CVS, it may work better now. All comments are, of course, welcome. > Apart from that, the rest of the code compiled fine (I did not > try running it yet), but MIPSpro did generate a bunch of > warnings. Most of them were about unused variables, but there > were a couple of "interesting" ones. Is there a mechanism > for submitting patches, and would there be an interest > for warning cleanup patches? Sourceforge, which hosts the OpenQuicktime project, has some funky systems for submitting/tracking bugs and patches. Drop by the Sourceforge project page: http://sourceforge.net/projects/openquicktime/ You can also directly email the devel mailing-list with your patch attached, I will put it in the CVS. Can you put the "interesting" warning list together with your patch ? - Antoine |

I'm personnaly not able to help you compiling OQT on MIPS cause I haven't
access to such baby.
But of course, all patches are welcome, the simplier for the moment is to
send them directly to
the dev-mailing list, then one of the developper will apply and test them.
Keep us aware of your progress,
Yann.

I tried compiling under IRIX 6.5 with the SGI MIPSpro
C compiler. I first ran into a problem with the configure
script. The following section:
my_cc_switch=
# AC_MSG_CHECKING(for -KPIC as C compilation switch)
cat > conftest.c <<__EOF
int main() { return 0;}
__EOF
my_c='${CC-cc} $CFLAGS -KPIC conftest.c -o conftest${ac_exeext}'
(eval echo configure:2574: \"$my_c\") 1>&5
(eval $my_c 1>/dev/null 2>conftest.log)
cat conftest.log 1>&5
if grep <conftest.log "option" >/dev/null
then
my_cc_switch="$my_cc_switch"
# AC_MSG_RESULT(no)
else
my_cc_switch="-KPIC"
# AC_MSG_RESULT(yes)
fi
rm -rf conftest*
tries to guess whether the -fpic or -KPIC flag should be used
by looking for the word "option" in the output of the compiler.
That's not what MIPSpro C says when presented with -fpic:
$ cc -c -fpic /tmp/foo.c
cc ERROR parsing -fpic: unknown flag
I'm not sure what the solution is here, but this test seems
to be pretty gcc-specific.
Apart from that, the rest of the code compiled fine (I did not
try running it yet), but MIPSpro did generate a bunch of
warnings. Most of them were about unused variables, but there
were a couple of "interesting" ones. Is there a mechanism
for submitting patches, and would there be an interest
for warning cleanup patches?
Thanks,
JF Panisset

Hi, I just read you are working on a "transcode" export module for openquicktime. That=B4s great. I was trying to write a simple export module for RGB/YV12 and PCM sound for use with Broadcast but failed for reasons that were listed in previous postings on your mailing list. Let me know, if you need some hints. BTW: transcode 0.6.0pre2-20010107 has added OQT support at the configure level.

Hello everybody, Just a small mail to inform you about the last news of OQT: - Nicolas has successfully ported OQT to Darwin. - He will soon create a Vorbis plugin for OQT (encoding/decoding) - Belial is working on an OQT Transcode export plugin, which should support all the OQT codecs and should be much more powerfull than the old OQTEncoder ;) - I've just put the new Openquicktime DirectShow demuxer in the CVS, it should be much more easy to compile than before even if you still need to play with some DLL ... Don't be nervous, it's not a final version but it can already play audio (I tested mp3) and video (hehehe ... 3ivx) synchronized ... Seeking has been implemented as well but it needs some complex threads locking which are still missing for the moment... and so it may block wmp ... - As soon as I've time, I will update the web site, it is really needed ;) Yann.

Hi,
While I have been playing with OpenQuicktime I have been having
problems with the OpenQuicktime plugin system. I am running
Debian/Linux 2.2...
It doesn't seem to be able to locate the plugins unless you set the
LD_LIBRARY_PATH environment variable - or compile in the full path
into the libopenquicktime library.
ldconfig seems to ignore any libraries that don't start 'lib'.
njh@mozart:~/OpenQuicktime/openquicktime-1.0-src$ /sbin/ldconfig -v
/sbin/ldconfig: version 1.9.11
/usr/local/lib:
libSDL-1.2.so.0 => libSDL-1.2.so.0.0.3
libopenquicktime.so => libopenquicktime.so
/usr/lib:
libgsm.so.1 => libgsm.so.1.0.10
libjpeg.so.62 => libjpeg.so.62.0.0
libgthread-1.2.so.0 => libgthread-1.2.so.0.0.7
....
Is there a nicer way of doing this ? Such as compiling in the install
path of the quicktime codecs ? (/usr/lib/quicktime_codecs/) ?
Or how about adding the install path to LD_LIBRARY_PATH at run time ?
nick.

Hi Nick, Even if the last CVS checkins are quite old, I can assure that we are working on it ;) I personnaly work on an OpenQuicktime DirectShow demuxer on Windows, as soon as it is completed (and committed ;), I will have to work on the integration with Gstreamer to update the Gstreamer Openquicktime plugins, and basically, we plan to release a new version soon with more codecs... If you're interested in implementing new functionalities, just send me a mail with your sourceforge login, and I will make you member of the project :) ... We also plan to create an OpenQuicktime output plugin to Transcode ... Yann.

Hi, Is anyone actively developing OpenQuicktime at the moment ? I plan to use it as part of my Third Year Computer Science project on streaming audio using QuickTime. I have written a broadcast program that streams Live MP3 audio on Linux to DSS. It currently uses Lame directly but I may use OpenQuicktime if it looks worthwhile (so I can use other codecs - IMA4 ?). I have had it running continuously for a few months and it has been working well - http://surge.soton.ac.uk. I would also like to be streaming Text and URLs to the clients... I would like people to be able to listen to our stream on Linux so I am looking into writing a Quicktime RTSP client for Linux - initially audio/text only. I have done a bit of work on OpenQuicktime - I have managed to get it working under Mac OS X/Darwin with Fink (fink.sourceforge.net). I know this sounds a little pointless (what with real Quicktime being avauilable !) but I would like my broadcaster to compile on any Unix... I am also working on getting the IMA4 codecs and raw codecs to work... I managed to get the 'twos' codec to work with a couple of lines saying memcpy ! nick. |
