What program/commands can I use on a linux dedicated server or amazon e2 to convert a video to mp4 h264 format that is compatible for desktop, iPhone, android and blackberry?

Take a look at these FFmpeg examples:

The 1st one should work in all, and the 2nd one probably will too. Encodes with Main profile, higher bitrate and larger frame sizes are good for desktop streaming but might not work in some devices./

I don’t have a simple answer, except to use lower complexity options like Baseline profile for widest coverage. And use AAC audio, because some devices do not support mp3 or not well. For vod we recommend Expression 4 Encoder for multi-bitrate encoding because of its key frame alignment capability. All the encodes in a set have to be the same profile when you encode with Expression 4, so choose Baseline.

It’s a different tool, but I only have the same answer, choose Baseline for wide coverage.

You are asking about the widest coverage, working on the most devices, so lowest common denominator, what works for all is simplified encoding parameters (eg. baseline profile) and aac audio. Just general advice.

On [http://www.encoding.com/using\_wowza\_media\_server](http://www.encoding.com/using_wowza_media_server) if I use Wowza Multi-bitrate Preset for Adaptive Bitrate output will it be compatible with most desktop, iPhone, android and blackberry ?

for multi-bitrate encoding you want me to change wowza\_multibitrate to main . I thought the whole deal with multi-bitrate video is to adjust according to the speed and device the viewer have
