Creating a viewable mpeg4 file for the 365 from a mp4 file made for a PC

Peter Norman

I have tried using ffmpeg to rip out the elementary stream and building the video object layer after that fact as this TI article recommends http://processors.wiki.ti.com/index.php/How_to_Extract_MPEG-4_Elementary_Stream_from_MP4_Container

Unfortunately, it did not work... has anyone else had to do this and if so how did you accomplish this?

Thanks in advance,

Peter,

1. If you want to use DM365 SP decoder then -

What is the source of MP4 file ? Has it been converted to DM365 specific format using the info provided in the below 2 posts?-

If yes, the you can extract the elementary stream from MP4/mov using ffmpeg and play it in DM365 using MPeg4 ASP decoder.

2. Also, We have latest MPEG4 ASP universal decoder available whcih can be integrated into DVSDK

This will not require any conversion and can directly play any mpeg4 SP/ASP elemantary streams (you still have to elementary stream using ffmpeg ).

Below links have details -

I suggest you go for option 2. Let us know if you face any issue.
