Encoder

We have HD MPEG-4 AVC .mp4 movie files. We would like to re-encode them to the MPEG-TS files, that will be served as the input for the HLS streaming. The Baseline Profile will be used, since the target devices are mobile phones. Now we have chance to offer streams in different qualities, so the mobile can select the proper based on current bearer/bandwidth CPU architecture used (ARM6/7, Neon, Tegra). The question is what are parameters we could learn to manipulate to have the optimal result for HLS (H.264/AAC):

• Resolution

• FPS

• Color model, color depth

• Bitrate – specifying this influences probably the other parameters, but this is not crucial for us since the WiFi is mandatory for us.

• What are other the relevant compression parameters

• Audio parameters

Thanks a lot Regards, STeN
