I have a ZTE Open and I have tried to play a video of format .mp4 on both FF OS version 1.1 and 1.2 but the video app does not see the video file. Instead it says "Add Videos to get started, Load videos on to the memory card."
The music app sees the music on the SD card fine. In settings if I go to 'media storage', it even says that there is 300MB worth of Movies on the card.
What happens when you record a video from your Firefox OS device? Does it show up in the Videos application?
Support for the following formats in Firefox uses operating system decoder support. This means coverage is not available across all platforms. We are working towards this goal.
Are you telling me the ZTE open can't play mp4 files at the moment?
