Totem couldn't handle H.264; mplayer2 did.

I have totem 3.0.1 and libgstreamer0.10-0 installed, and youtube & other videos play fine, but an emailed apple-flavoured clip: $ file Desktop/IMG_8015.MOV Desktop/IMG_8015.MOV: ISO Media, Apple QuickTime movie shows only as grey/green/white diagonal bands, although the audio replays fine. Totem shows the properties of the clip as: Dimensions: 568 x 320 Codec: H.264 / AVC Framerate: 30 frames per second Bitrate: 701 kbps Installing mplayer2 was the first fix which worked. Is totem not up to playing Apple clips, or does it just need a config tweak / plugin ? The totem version might not be the latest - I'm on Debian 7.8.0. Erik
