Hello list,
I'm running into a problem where the rendered video is not the
requested width : 682 instead of 640.
* The MELT XML file starts with
<mlt LC_NUMERIC="en_US.UTF-8">
<profile width="640" height="360" display_aspect_num="16"
display_aspect_den="9" sample_aspect_num="1" sample_aspect_den="1"/>
etc.
* I'm generating the video with the following command line
melt file.xml -consumer avformat:file.mp4 r=24 s=640x360 strict=experimental
* ffprobe seems to say the format is 640x360 as requested

* but MacOSX finder says the video dimensions are 682 x 360, and when
I launch the video with either Quicktime or VLC, there are black
borders on the left and on the right.
I'm using melt v0.9.1, ffmpeg version N-59046-g1d0995e
Have I done something wrong with the profile definition or the command line ?
Many thanks in advance for your help !
All the best
Geoffroy
