Just got my F807 and currently transferring songs... and I got a few questions already lol...
1. how to disable speakers? the speakers are kinda annoying to me lol...
2. cover.jpg doesnt work.. so what software do you guys use for embedding album art?
3. any suggested resolution? i noticed that 300x300 is abit small for album art.
2. Why would any one use Cover.jpg? I always embed my album art into the files by MP3tag - an excellent tag editor with support for nearly anything.
3. 500x500, 640x640, sizes like that are usually universally acceptable for most screens and applications. However, I find Poweramp's sweet spot to be around 600x600 or 640x640, any lower than 500x500 tends to look visibly blurry and anything extremely large (1000x1000 and beyond) tends to show aliasing due to the resizing algorithm in place. The default Sony player however seems to just be bad with album art altogether, and all my album-art looks blurry. Of course, if you have a retina device such as an iPod or iPad, having huge album art is a major boon.
Speaking of which, I tried using the volume rocker whilst the Walkman was locked again, with Poweramp. It works! However it does have different behavior from normal Android devices as you must press the rocker each time to move a step down the Master volume setting, and holding on the button does not work. But otherwise, the volume rocker does work when the device is locked.
If you are referring to format support, I believe it supports the usual .MP4, .3GP and .AVI, but .AVI support might be limited, especially with DivX. I recommend using MP4 in 720p or 1080p resolutions, at bit rates of less than 17Mbps. In general, videos off YouTube will work for example. Handbrake is a good encoder.
