Question on CAPS

[Shishir Pokharel]

Your video resolution is not matching with the caps you have set – try using videoscale element in your pipeline if you want to scale your resolution.

Subject: Question on CAPS

I am trying to run: (notice the CAPS). Which fails

gst-launch-1.0 filesrc location=entry.mp4 '!' qtdemux '!' video/x-h264,width=640,height=480 '!' h264parse '!' mpegtsmux '!' hlssink playlist-root=https://192.168.1.8/~silentm/hlssink location=/home/silentm/public_html/hlssink/hlssink.camera.560.%05d.ts target-duration=1 max-files=3 playlist-length=2 playlist-location=/home/silentm/public_html/hlssink/playlist.camera.560.m3u8

Remove the width and height and it works.
gst-launch-1.0 filesrc location=entry.mp4 '!' qtdemux '!' video/x-h264 '!' h264parse '!' mpegtsmux '!' hlssink playlist-root=https://192.168.1.8/~silentm/hlssink location=/home/silentm/public_html/hlssink/hlssink.camera.560.%05d.ts target-duration=1 max-files=3 playlist-length=2 playlist-location=/home/silentm/public_html/hlssink/playlist.camera.560.m3u8

What am I doing wrong ? The original image is 1920x1080 and I want to make that smaller at 640x480.

Thanks,

Jerry
