Description Karl (reporter) 2010-05-29 00:41:16 UTC

SOFTWARE VERSION:
10.2010.19-1

EXACT STEPS LEADING TO PROBLEM: 

1. transcode a mpeg2 ts stream to h264 with asf muxer
   for example with following vlc transcode options (I used VLC 1.0.5 on win7)

--sout="#transcode{venc=x264{profile=baseline,level=3.0},vcodec=h264,vb=800,width=800,height=480,acodec=mp4a,ab=128,audio-sync
}:std{access=file,mux=asf,dst=C:\\out.mp4}"

   or for http live streaming:

--sout="#transcode{venc=x264{profile=baseline,level=3.0},vcodec=h264,vb=800,width=800,height=480,acodec=mp4a,ab=128,audio-sync
}:std{access=http,mux=asf,dst=:8080/out.mp4}"

2. open transcoded video file/stream
3. aspect ratio is not detected correctly

EXPECTED OUTCOME:

video file/stream is played with correct aspect ratio

ACTUAL OUTCOME:

video is played with wrong aspect ratio (stretched to whole screen)

REPRODUCIBILITY:
always

OTHER COMMENTS:

I have created two test files.

First transcoded with asf muxer.
http://www.nanohcv.de/asf4_3.mp4

Second transcoded wiht mp4 muxer.
http://www.nanohcv.de/mp4_4_3.mp4

The second one is played with correct aspect ratio with the fix from Felipe
Contreras (https://bugs.maemo.org/show_bug.cgi?id=7465)


I have also made some tests with other media players on different systems.
- VLC (Windows and Linux) on PC detects the correct aspect ratio
- MPlayer on PC detects the correct aspect ratio
- MPlayer on N900 detects the correct aspect ratio
- Totem Player (ubuntu 10.4) detects the correct aspect ratio
- Media Player on N900 does not detect the correct aspect ratio

Hi,
what is the output on the device when opening the videofile via
gst-launch playbin2 uri=file:///home/user/MyDocs/.videos/videoname.foo

Hi,

Output from gst-launch on N900:

Maybe helpful:
The output from gst-launch in Ubuntu where the file is played with correct
aspect ratio.
