[MPlayer-dev-eng] [PATCH] print interlacing info on decode

[Jarek Czekalski]

  Ok, I'm posting again in a more proper manner, even including an 
attachement. This is the same I posted yesterday, except that I cleared 
the warning: no prototype.

I don't know where to put this prototype. This function shouldn't be 
visible outside the file, so I put the prototype just before the definition.

Could you review it and maybe commit?

This time I'm attaching also a bash script (test_scan) presenting the 
problem in handling mpi->fields flags by mencoder. That's the output I 
get from the script:

Testing test_progr.avi
[video decoder] Scan type: progressive
Testing test_tff.avi
[video decoder] Scan type: interlaced, tff
Testing test_bff.avi
[video decoder] Scan type: interlaced, bff
Following files are created by lavc ildct with tff/bff autodetection
Testing test_tff2.avi
[video decoder] Scan type: interlaced, tff
Testing test_bff2.avi
[video decoder] Scan type: interlaced, tff
Autodetection didn't work, mpi->fields==0 at the encoding time
Finally let's see that mencoder sees the proper flags at the decoding time
[video decoder] Scan type: interlaced, bff

All this is related to bugzilla 1786:
