gstreamer custom element

[Duchassin Frederic]

If somebody can have a look at debug file in order to give me a clue.

2 zip archive containing dot files : 

-          The first is a pipeline from a file and is working.

-          The second is a live stream from udp and is not working.

Hello,

 

I try to make my own element called “t2mi” : this element take a t2-mi
stream as input as output an mpeg2-ts stream.

So using these pipeline :

 

(this first pipeline create a file called out.ts which contain valid
mpeg2-ts)

gst-launch-1.0 -v udpsrc address=239.0.0.1 port=1234 buffer-size=300000000
do-timestamp=false ! queue ! t2mi pid=64 ! queue ! filesink
location=/home/t2misample/out.ts

 

+

 

(this second pipeline read the out.ts file and display the decoded video)

gst-launch-1.0 -v filesrc location=/home/t2misample/out.ts blocksize=564 !
tsdemux name=d ! multiqueue name=q use-buffering=1 d. ! q. q.  ! queue
max-size-bytes=100000000 max-size-time=0 ! vpudec ! queue
max-size-bytes=100000000 max-size-time=0 ! imxipuvideosink q. ! queue
max-size-bytes=100000000 max-size-time=0 ! decodebin ! queue
max-size-bytes=100000000 max-size-time=0 ! audioconvert ! volume volume=10 !
alsasink

 

 

 

So my element seems working but when I use the following pipeline, it
doesn’t work anymore  :

gst-launch-1.0 -v udpsrc address=239.0.0.1 port=1234 buffer-size=300000000
do-timestamp=false ! queue ! t2mi pid=64 ! queue ! tsdemux name=d !
multiqueue name=q use-buffering=1 d. ! q. q.  ! queue
max-size-bytes=100000000 max-size-time=0 ! vpudec ! queue
max-size-bytes=100000000 max-size-time=0 ! imxipuvideosink q. ! queue
max-size-bytes=100000000 max-size-time=0 ! decodebin ! queue
max-size-bytes=100000000 max-size-time=0 ! audioconvert ! volume volume=10 !
alsasink

 

So when I use a filesink + filesrc and 2 pipeline, it’s working. But when I
use only one pipeline it doesn’t work.

So my question is why ?

 

Thanks in advance for your help.

 

Frederic
