TS-File not seekable

[BGraaf]

Hi @ all,

 

I’ve an issue with my own program using dvbbasebin:

The pipe: gst-launch-1.0 dvbbasebin adapter=1 frequency=12544000 program-numbers="17501" polarity="h" symbol-rate=22000 ! queue ! tsparse ! filesink location=test_ts.mpg

Results a file that has no problem with seeking

But my own program:

Is the result not seekable!

 

Something missing to generate a seekable ts-file?

 

Thanks a lot and sorry for this long mail!

Hi,

You should use the "-e" option in order to insert an EOS signal when you do crtl+c.

It is likely a problem closing properly the file.

Best,

-e is a good thing to pass in general when you intend to stop streaming
via Control-C, but it's unlikely to be the issue here. Unlike other
containers with dedicated headers/indexes, there shouldn't be anything
to 'fix up' after mpeg-ts bytes have been written out. Worst case
scenario is that you're missing a couple of seconds in the file if you
don't shut down properly.

Cheers
