[James Almer]

ffmpeg | branch: release/2.1 | James Almer <jamrial at gmail.com> | Thu Dec 12 03:34:19 2013 -0300| [fc82ba06ee87e16b65ba1a426641e3484a69da71] | committer: James Almer

avformat/oggparseopus: Check opus_duration() return value

Regression since 39d11d599cd292485fe991cd22e10d7a1738b3bc

os->pduration would be wrongly assigned a negative value on invalid packets
instead of aborting.
