  • Forum Post: Re: How does one convert a video file into a DM355 mpeg4 decoder format?

    Bernie Thompson TI
    It may be a little deep, but since I am not that familiar with the Arcsoft tool I can at least suggest what settings you would need to have in the MPEG4 to have it be decodable by the DM355. If you look in your DVSDK install in something like dvsdk_1_30_00_40\dm355_codecs_1_12_000\packages\ti\sdo\codecs...

    I agree, if you ever do run into this collateral again, please post it here. I have been working with this platform since it came out and do not recall such collateral, but would definitely be interested in seeing it.

    My first thought on this is the same as Juan's, you may have to use some demuxing software like GStreamer to allow the DM355 to play the .avi file, there is a good article on using GStreamer with the DM355 at the wiki site here . Unfortunately I have not had a chance to use the Arcsoft software myself...

    Thank you for the information PhilippS, using the venc application like this with a yuv file should allow a user to encode a DM355 compatible MPEG4 stream without having to pipe the video in through a analog source. I am not sure what you mean by 'climbs off by horizontal axis'? If you mean...

    Hello everyone. I have a tough question to ask. I use dm355 to capture and encode a mpeg4 bitstream. In the same network section, there's a server takes charge of decoding the bitstream which is sent by dm355 with RTP. Now the problem is that the decoder of the server is a XVID decoder, it seems...

    I wonder if anyone can clarify something in the 'MPEG4 Simple Profile Encoder Codec on DM355' spec for me. We are trying to configure mpeg4enc to give a constant (+/- 10%) bitrate.Also, this bitrate needs to be quite low, of course, as we'll be sending that data over a 3G, possibly 2G...

    I have both display and mpeg4 encoding working on a DM355 using IPIPE at a resolution of 720x480, but as soon as I try to increase this resolution to 720p (1280x720), my encoded video is distorted/scrambled (as though there is something still expecting 720x480).

    Hi. All~~ Could you tell me the meaning of "closed" in the following description on codec support of DM365 ? The bitstream encoded with XVid [ D1, SP Level1] which is decoded with DM6446 well, produces "fatal decoding error" on DM365. I think it is because DM365 only can decode...

    Ok so do you think that I can use a program like ffmpeg to stream video on the network (TCP/IP) and in parallel, send the sensors values through something simple like telnet for example? Would it be easy to add a timestamp to the H.264/MPEG4 video? Thanks, Mike

    Try copying the DSI (Decoder Specific Information) from the beginning of the stream. I.E. everything up to the first 0x1B6. Then put that in the beginning of each file. May sure that each file starts with an I frame.
