06deaf8ad3 idcin: return 0 from idcin_read_packet() on success. 
This matches the AVInputFormat.read_packet() API.

7040e479a1 idcin: allow seeking back to the first packet 
Also, do not allow seek-by-byte, as there is no way to find the next packet
boundary.

ccc0ffb1ba idcin: set start_time and packet duration instead of manually tracking pts. 
Also, use 1 / sample_rate for audio stream time_base.

71194ef6a8 rtpdec_vp8: Mark broken packets with AV_PKT_FLAG_CORRUPT 
This allows the caller to either include them (and get more packets
decoded, but possibly some nonperfect frames), or discard them (by
setting fflags=discardcorrupt).

Fixes Ticket2123

I cannot reproduce any regressions by flipping the wrong condition
to how it should have been.

119d70db50 lavf/mux: do not pass a copy of the packet to write_packet(). 
Sometimes the muxer modifies the packet, like for instance lavf/mp3enc
changing pkt->destruct in order to keep a copy. These changes must be
kept, even though the muxer behaviour is questionable. Regression since
0072116.

Fixes #2124.

59220d559b oggenc: add a page_duration option and deprecate the pagesize option 
This uses page duration instead of byte size to determine when to buffer
the page. Also, it tries to avoid continued pages by buffering the current
page if there are already packets in the page and adding the next packet
would require it to be continued on a new page. This can improve seeking
performance.

The default page duration is 1 second, which is much saner than filling
all page segments by default.
