Sorry, it was my fault.  Now it works perfectly.  (Wow!)

[gst-devel] seek testing results

[Joshua N Pritikin <vishnu@po...>]

i stored an index with gstfileindex.  The index is loaded by
my media player.  Two writers are resolved, mpeg2dec and
mpegdemux.sink.  i send a seek event, same as the indexmpeg
example.  When i restart playback, the audio continues as
if the seek never happened.  The video is blank for a few
frames and then continues in sync with the audio.

It seems like i'm missing some flushes or something.

[gst-devel] mysterious memory problem

[Joshua N Pritikin <vishnu@po...>]

When i run gst-plugins/examples/indexmpeg on a big file (600M) with
gstfileindex then i get a SEGV in some random place (usually the
mpeg2dec library).  Can anyone else reproduce this?

On the other hand, the SEGV goes away if i use gstmemindex or if
i add the following code to gstfileindex (near g_array_insert_val):

    if (id_index->array->len == 0) {
      g_array_set_size (id_index->array, 10000);
      g_array_set_size (id_index->array, 0);
    }

This avoids any additional g_realloc calls when adding elements
to the g_array ... and the SEGV disappears.  Strange.

[gst-devel] Testing bug 98062

[Andrew Turner <zxombie@ho...>]

Hello,

Could people please test the last attachment to bug 98062.
It should mean autogen.sh will work almost the same. The only difference 
is when you try to do something like:

  ./autogen.sh --prefix /whatever

as you will need to change it to (notice the =)

./autogen.sh --prefix=/whatever

It is the same with --with-automake and --with-autoconf.

[gst-devel] indexer API

[Joshua N Pritikin <vishnu@po...>]

Wim, can you pass in the object type name through add_id?  Since
i do indexing and playback with completely different pipelines,
it doesn't work to match on "writer_string" in the resolve_writer
callback.

However, the resolve would work if i could match on the GType name.

Hi Dan, thanks for the patch.

I've included a slightly updated version which changes the way setting the
caps is done, and error/warning output. I also changed some of the tabbed 
indents to spaces, to keep the format consistent, and freed the allocated
buffer pool when returning to the NULL state.

I've held off applying the patch pending a response from the kino developers
as to whether they mind us using their snippet of GPL'd code in an LGPL
plugin.

Cheers,
Jan.

My ffmpeg plugin doesn't do audio. And it still has some minor
performance gaps (examples: it memcpy()s every decoded frame into a
separately allocated buffer instead of decoding to a separate buffer at
once, it doesn't do audio, it doesn't do encoding yet...

Ohwell. I guess encoding is less of an issue, since for encoding, you
need to specify the codec anyway, so you could just as well use ffenc_*
for that. We have enough audio plugins (except for WMA - so I might
still do it after all, but not short-term)...

Only thing left is spider testing (i.e., it might actually just work -
no clue). I guess I just need to remove all video plugins and see if
autoplugging then works. Any better option? I'll work on this pretty
soon. Spider is the only 'important' feature here - the others are long
term.

I managed to get marlin to load a divx file which I guess was using it
(because I deleted wincodec files...), so it works with spider, for
audio output at least.

[gst-devel] mpeg2dec in gst-plugins-0.5.0/

[Martin Soto <soto@in...>]

Hi all!

I'm trying to compile gst-plugins-0.5.0 but I don't manage to compile
the mpeg2dec plugin. The configure script seems to be looking for
libcpuaccell > 0.3, but I cannot find that anywhere around (google
brings a few matches related to mpeg2dec, but the current version of it
(0.3.1) doesn't build such a library). 

Is this plugin supposed to work at all in 0.5.0?  How can I enable it?

Thanks,

M. S.

[gst-devel] Success story and roadmap

[Christian Fredrik Kalager Schaller <Uraeus@li...>]

Hi team,
I managed to play songs and video using Wim's opt scheduler today so it
seems we finally have a good alternative to work around the thread
issues the plague us. Thanks Wim!

Anyway I thought I send out this mail to inquire about status of certain
core components.

First of all what is the status of Spider? Steve you where working on
this (or planned to), but I haven't heard or seen anything for some
time. Any news? Also some info on status of gst-player atm would be
good. A 0.5.x compatible release would be nice.

ffmpeg plugin. As I understand it works for using gst-launch, but we
still need some work before we can use it with spider. Anyone working on
that? Ronald? 

I also have the new Red Hat beta Phoebe installed on my laptop now. It
bundles GStreamer as most of you know. I will try and do some testing of
different compile flags on glibc on it to see if I can get someone at RH
to check why we have so much thread issues on RH.

[gst-devel] frame accurate seeking

[Joshua N Pritikin <vishnu@po...>]

i'm going to resume work on a persistent version of gstmemindex.
After that, i intend to verify mpeg2dec seeking accuracy
against cinelerra.  If i seek to a time offset in cinelerra
then i should get exactly the same frame using the same
time offset with gstreamer.

i can't tolerate any uncertainty in the position of my
in and out points.

Will the byte-offset returned by index_seek (mpeg2dec)
really be prior to the correct I-frame?  i have some
doubt because i know there is various other stuff
in the mpeg systems stream.

Anyway, i'll find out via experimentation.

[gst-devel] Scheduler issues.

[iain <iain@pr...>]

Hey, I'm having issues destroying a pipeline.
Pipeline is custom-src ! f2i ! encoder ! filesink all in a GstThread.

Problem is that when I do gst_object_unref on the container bin, it
removes the f2i, then the sink, then the src and then crashes in
gst_basic_element_remove_element. Adding the debugging in the attached
patch prints out this:

removing element "f2i" from scheduler
chain: 0x8332210
removing element "sink" from scheduler
chain: 0x8332210
removing element "src" from scheduler
chain: (nil)
removing element "encoder" from scheduler
chain: 0x8332210

Without the if (chain == NULL) check in the patch, it then crashes
somewhere in gst_basic_scheduler_chain_remove_element, probably because
the chain is NULL.

The patch works, as in, it stops it from crashing, but I'm guessing the
NULL chain is just a symptom of something else. I just don't have the
knowledge to know what. Any ideas?

[gst-devel] ffmpeg & etc

[Joshua N Pritikin <vishnu@po...>]

i am happy to see that ffmpeg CVS is being sucked into
gstreamer.  However, the makefile tries to build ffmpeg
even if it is missing (e.g. no internet connection).
Attached is a trivial patch to fix it.

Wim, i am excited to see that you made the indexer changes
i was wanting.  i just got back from vacation.  i will try
out the new stuff as soon as possible.
