 Summary of the bug:

 nvenc fails on snapshot build, always with the same error:
 {{{
 Assertion !avpkt->data || avpkt->buf failed at libavcodec/encode.c:438
 }}}
 the bug is NOT present in the last stable version, 4.2.1

 the specific code differences in encode.c that seem to be the source of
 the problem are new lines 435-438:
 {{{
 435 if (!ret)
 436 // Encoders must always return ref-counted buffers.
 437 // Side-data only packets have no data and can be not ref-counted.
 438 av_assert0(!avpkt->data || avpkt->buf);
 439 return ret;
 }}}
 These lines are NOT present in the 4.2.1 source for libavcodec/encode.c

 Log/report files showing two failures using the snapshot build and one
 success (truncated) using the 4.2.1 build are submitted via VideoLAN.
 Also submitted is a linux diff file showing the diffences between the two
 versions of encode.c.
