#1850: version 1.0-tessus can't encode from DV to MP4
---------------------------------+----------------------------------
Reporter: cmarrin | Type: defect
Status: new | Priority: normal
Component: FFmpeg | Version: 1.0
Keywords: | Blocked By:
Blocking: | Reproduced by developer: 0

---------------------------------+----------------------------------
Using ffmpeg version 1.0-tessus (obtained from
http://www.evermeet.cx/ffmpeg/). Run:
ffmpeg -i input.dv output.mp4
produces a file with black video, while:
ffmpeg -i input.dv output.avi
produces correct video
The same thing happens with ffmpeg version 0.11.1-tessus.
But when I try to do the DV -> MP4 encoding using FFmpeg version
SVN-r15883, which is a version I built a while back using macports it
performs correctly.
Here is the output from a failed run:

====================
The test file I was using was a file that was actually created using an
older version of ffmpeg. As you can see it had no audio, only a video
stream. But that file is 35MB, so I won't upload it. I also tried a short
(1.5MB) DV clip from a Sony DV camcorder. It fails in the same way, so I
have attached it.
