patch for dwLength (499 bytes, patch)
2006-09-15 16:53 UTC, Yves Lefebvre 		committed Details | Review

Description Yves Lefebvre 2006-09-15 16:49:54 UTC 
I found that if I generate a big avi with this pipeline for example :
gst-launch-0.10 videotestsrc num-buffers=22000 ! video/x-raw-yuv,format=\(fourcc\)I420,width=320,height=240,framerate=15/1 ! avimux ! filesink location=BigAvi320x240.avi

I can open it properly in quicktime (under windows) and it show me a duration of 24:26.
However, opening the same file in windows media player show a duration of 20:13 wich correspond to the first chunk of the open dml AVI.

patch for dwLength

I notice that the "strh" dwLength value seems wrong in the AVI. It only contain the number of frame of the first AVI chunk and not the total length.

With this patch, the file duration is now displayed correctly in window media player and the AVI play completely
