AW: Help - Using GStreamer decoders to decode

[Bernhard Graaf]

Hi Ashwini,

 

Do you have more details about what appsrc, decoder and appsink you want to
use? It's a little bit different.

Betreff: Help - Using GStreamer decoders to decode

 

Hi All,

 

  I am writing an mediaplay application in which i have to use GStreamer
decoders to decode data and send it back. For the purpose I am going to use
"appsrc ! decoder ! appsink" . Where decoder can be a specific decoder or
decodebin. 

 

I will be reading the file, demuxing it and then send the demuxed packet to
GStreamer decoder part as described above. Here I want to know few
things....

 

1.	Does the  decoder in gstreamer output a complete Frame or is it
partial data? I assume it to be a complete frame... please correct my
assumption.
2.	Can I know from the output buffer/frame (at src pad of decoder),
whether it is a Key-frame or not?
3.	Is it possible to check whether the complete frame can be generated
from the given demuxed data or does it require more?
4.	Is there any way to get the PTS of the decoded frame?

Please help, as this is urgent for me. 

 

Thanks,

Ashwini
