I believe it is at least partially already done there (with exception
for the SAR?).

Michael can you say which is the right way to tackle the problem?

Should:
picture->pkt_dts= avpkt->dts;
picture->pkt_pos= avpkt->pos;

be set only if threads are disabled?

The first line was set in:

commit b38f008ea64cc5c0087fc9804569338ef005897c

    Frame-based multithreading framework using pthreads
    
    See doc/multithreading.txt for details on use in codecs.

the second was added by me as I added the pkt_pos field.

Is there some way to enable threading in fate?
