Bug#703140: avconv: [mp4] Application provided invalid, non monotonically increasing dts to muxer in stream \ av_interleaved_write_frame(): Invalid argument

[Bob Bib]

Package: libav-tools
Version: 6:0.8.5-1
Severity: normal

Dear Maintainer,

the current wheezy/sid avconv (and one from experimental libav/6:9.3-1 too)
fails to process some slightly damaged FLV file.
(Switching output from MP4 to FLV doesn't help either).


$ avconv -i test01.flv -codec copy test02.mp4
