DM355 - Arcsoft Video Converter Tool

Hi,

This is a TI customized version of Arcsoft tool for DM355; Arcsoft lets TI distributed this for free so long as TI keeps a tab of who TI gave this tool to. So if you want to obtain this tool, please contact the local sale office and provide your name, company name, your email and phone number and we try to send the tool to you.

Note that this is a temporary fix to the non-universal MPEG-4 codec issue on DM355; this issue is not existed on the DM365/DM368. TI recommends for new designs, you will likely have a much better experience with DM365/DM368 and eliminate the need for this tool. 

Hope this helps.

Thanks.

Hi,

I can try to answer your questions the best I can. Hopefully someone in the community can jump in to add/correct.

Universal codec means it can decode files encoded somewhere else (by software program or another chip). 

In the case of DM355, the MPEG4 decoder (closed decoder) could only decode files encoded via DM355; if a user wanted to decode a file encoded somewhere else, they would need to pass file thru Arcsoft software to get it in the right format for DM355 to be able to decode it. 

For DM365, MPEG4 decoder is a universal decoder, thus user does not need Arcsoft software; this is why so many customers have shifted to using DM365 instead. 

I am not too familiar with DivX, but my understanding is that this is a container (as opposed to elementary stream) format that can include either MPEG-4 or H.264 elementary streams within the container.  DM365 codec decode elementary streams only; therefore, user will have to develop (or port) software to pull the elementary stream before sending it to DM365 codec for decoding.  Programs such as GStreamer are used to go between popular container formats and elementary stream, or user can develop its own custom software.

Hope this helps.

Thanks,
