I am not sure about RTP streaming with FFMPEG - I guess it will depend on what codecs the phone supports as well (assuming it does support RTSP / RTP). RTP is certainly a good choice for streaming in general, as it is designed for it, where the other container formats often are not (or have been badly designed for it). I think that ffmpeg supports h.264 for RTP streaming, which will almost certainly be supported by the phone. As for audio, I am not as certain. > > 2) You mentioned, > The best solution to this just now is to pre-convert any videos into > 3gp > format and then stream them directly. > But I do not understand what you say :( I am able to convert my > content to > .mp4 that plays on Android.

I think it uses AAC by default to encode mp4 regardless of if you compiled it with AAC support. Beyond that, I don't know too much about ffserver and ffmpeg interaction.
