Hi guys,

I'm using proxy plugin to decouple pipelines but I have an issue when I try to decouple two pipelines and use h264 data in between. Just mention that the problem does not exist if:

1. proxysink/proxysrc are part of the same pipeline.
2. I use RAW data instead.
3. h264 data is inside a container like 'mpegts'.

example 1

This is 1 pipeline executing 2 'sub' pipelines which are communicated through proxysink/proxysrc. Here, h264 data flows properly from one sub-pipeline to the other.

Here how the components are linked inside the same pipeline:

sub-pipeline1:
filesrc ! qtdemux ! multiqueue ! \
h264parse ! video/x-h264,stream-format=byte-stream,aligment=au ! queue ! proxysink \
\
sub-pipeline2:
proxysrc ! avdec_h264 ! video/x-raw ! queue ! autovideosink 

Here the graph:

example 2

This is when I try the above but sub-pipelines are executed in different pipelines. So, something like:

Pipeline 1:

sub-pipeline1:
filesrc ! qtdemux ! multiqueue ! \
h264parse ! video/x-h264,stream-format=byte-stream,aligment=au ! queue ! proxysink

Pipeline 2:

sub-pipeline1:
proxysrc ! avdec_h264 ! video/x-raw ! queue ! autovideosink 

In this case, I get the next error:

0:00:00.090315812 48480      0x246ab60 WARN                 qtdemux qtdemux.c:6605:gst_qtdemux_loop:<qtdemux0> error: Internal data stream error.

Here the graph for the 1st pipeline:

Here the graph for the 2st pipeline:

Questions

Any idea why this is happening?

What is funny is that if you enable debug level 7 then, the 2nd example works fine.

Here the log file with level 5 in case it can help: ex0-proxy-r1.log

Thanks!
