I did not have time to run it before yesterday. Now I tried it
last night and it crashed after about 12.5h with the error you
reported as well (Incomplete auxiliary stream).<br>
<br>
How is it going with the git HEAD?<br>
<br>

I will let it run for some hours today, but I will have
to restart to give a presentation tomorrow. I will make
some thorough test after. I will not pull from the
repository for the moment. If we get different results,
we have a starting point to look for. But anyway I think
I am quite close to the HEAD, as I pulled about two
weeks ago.<br>

After 8-24 hours of continuous running I have
noticed an error indicating no "enough data to read
auxiliary data" or something to that effect. I was
instructed to get the Git tip of gstreamer and
gst-plugins-base and re-run my test which I am doing
right now.<br>

<div>Hi Rob,<br>
<br>
Brilliant stuff! I did not answer earlier,
because I wanted to test for a longer time. I
tested it with the pipeline<br>
<br>
gst-launch-1.0 --gst-debug=gstv4l2bufferpool:5
uvch264src device=/dev/video1 name=src
auto-start=true src.vfsrc ! queue ! fakesink
src.vidsrc ! queue ! video/x-h264 ! fakesink<br>
<br>
and patch [1] and it run for 24h. There was no
memory leak as far as I can tell. I posted the
patch because additionally to your patch for
gstuvch264_mjpgdemux.c, I did not remove some
changes I did (and forgot to remove) in
gstv4l2bufferpool.c. But I do not think that
they have an effect at all.<br>
<br>
I am now testing with the patch you proposed
in gstuvch264_mjpgdemux.c only, stashing all
changes made in gstv4l2bufferpool.c. It seems
to run without memory leak or other problems.
I will report back about stability at the end
of the week.<br>
<br>
Thanks a lot for your effort!<br>

It looks as though this patch fixes

well. It is against

It works for
me. I am
monitoring the
memory only
with htop at
the moment,
but it seems
to be stable.
I think the
memory leak
stems from the
fact that
max_buffers is
set to 0, so
it will always
make the
buffer bigger
and bigger. I
think that is
generally a
bad idea. This
might affect
also plain

I also wanted
to note that
when you apply
the
aforementioned
"hack" to
emulate the
default
operation of
v4l2src in
version 0.10
("always-copy=true")
with the
pipeline
below, your
system will
run out of
memory due to
a memory
leak. It will
then kill off
the gst-launch
process
instantiated
to run your
pipeline.
However, your
pipeline will
run for quite
a bit (a lot
longer than
the previous
36 seconds
noted by Yusuf

months ago).<br>

In version
0.10 v4l2src
used to have a
property to
force buffers
from it's pool
to always be
copied prior
to being
pushed out.
This property
was called
"always-copy"
and defaulted
to "true". It
seems that
this was
removed in
version 1.x.
If you go to
version 1.x
good plugins
and change
"copy_threadhold"
from 2 to 100
you
effectively
get the same
behaviour with
1.x in this
regard (same
as
"always-copy=true"
default in
0.10 v4l2src)
and there is
no error after
30 some odd
seconds that
causes the
stream to
abort.<br>

To figure out

and what is
different in
the diseased
frame I
printed out
the debug line
[line 508]
that was
already in the
code,
augmented with
the total size
of the buffer.
The original
line was:<br>
<br>
GST_DEBUG_OBJECT
(self,<br>
"Found APP4

JPG: %d-%d -
APP4: %d -
%d",
segment_size,<br>
last_offset,
i, i, i + 2 +
segment_size);<br>
<br>
I print for
each time in
the loop
(before the
sanity test
that will fail
finally):<br>
<br>
printf("Found
APP4 marker
(%d). JPG:
%d-%d - APP4:
%d - %d -
size: %d\n",
segment_size,<br>
last_offset,
i, i, i + 2 +
segment_size,
(int)size);<br>
<br>
What I get for
a normal frame
is about this.
The total
buffer size
changes and
also the size
of the first
APP4 chunk,
however, I
always seem to
get 4 blocks
for each
frame. The
segment size
of the first
marker differs
between the
individual
frames, while
the 2nd, 3rd
and 4th
markers are
the same size
all the time
as far as I
can tell:<br>

<br>
As you can see
it seems as
the last
segment
reaches out of
the total size
of the buffer.
As the last
segment seems
to be always
of a length
22566, I think
for some
reason (that
does not
happen in
gstreamer
0.10) a piece
of the h264
stream is
missing in
this
particular
buffer.<br>
<br>
The number of
bytes getting
lost is not
the same for
different
trials,
neither is the
cut-off. For
my second
trial I got:<br>
<br>
Found APP4
marker
(22566). JPG:
144796-144796
- APP4: 144796
- 167364 -
size: 165815<br>
<br>
So where are
these bytes?
And why are
they missing
so regularly?
