Bug Description

Hello,

it is currently not possible encode video files to WebM with avconv with 2-pass encoding.

The first pass succeeds, but on the second avconv failes with an error message like:

[webm @ 0x24ca040] Application provided invalid, non monotonically increasing dts to muxer in stream 0: 33 >= 33
av_interleaved_write_frame(): Invalid argument

(See attached file for full log of both avconv commands)

This seems to happen with input files in arbitrary formats.

Kind regards,
Jan
