Summary0002821: When I load this MTS file the waveform is incorrectly generated
DescriptionWhen I load this MTS file ( [^]) the waveform is incorrectly generated. It looks like the 2nd half of the clip is muted. The waveform is perfectly flat for that part. The secondary but bigger problem is when I put the clip in a project the cut in and out points do not render with the same timings the project monitor previewed.
Steps To ReproduceLoad the file and place it on the timeline.

The file is fine for me (recent git of MLT and FFmpeg). Either the bug was fixed in MLT, or it is a bug in the libav version of Ubuntu.

Can you post the result of this command in a terminal:

avconv -i 00888.MTS

Thanks for the quick response. I'll see if I can download some newer code.

$ avconv -i Videos/STREAM2/00888.MTS

I installed
but it didn't seem to change the waveform generation.

I found a workaround however. Running
avconv -i 00888.MTS -vcodec copy -acodec copy 00888.mp4
and using 00888.mp4 seemed to do the trick.
