  • Forum Post: h264fhdvenc codec outputs 0 encoded bytes

    Nir Aloni
    I use the h264fhdvenc codec (version 01.10.01.00 November 2009) with the DM6467. While running TI's DVSDK encode demo, I can see that the encoder outputs 0 encoded bytes when capturing the attached full-screen images. What is the reason for this?

    Nir Aloni
    In order to implement a workaround for a problem I have, I want to reset my decoder on the DM6467 using XDM_RESET. Since my CODEC was an old one (1.00.011) which does not support XDM_RESET, I downloaded a newer one (1.10.04.00). I compiled the DVSDK with the new CODEC, but when I try to run my application...

  • Forum Post: increasing noise at black areas after decoding

    Nir Aloni
    Hello, In my streaming application I have two boards based on DM6467 - one for encoding and the other for decoding. The encoding board is connected to a video source and the decoding board is connected to a display. I notice that while streaming, as time progresses, noise accumulates on black...

  • Forum Post: Can DM6467 decode 6 D1 at the same time?

    Saige Lin
    I decode 6 D1 h264 bit stream, and total bit rate is about 10Mbps. But I use the 6 decoders at the same time, the output frames are something wrong. The frame's x is 0 and y is very large number (like 3990752). I use the 5 decoders at the same time, and they work fine. Thanks & B...

    Hi, In TI's H.264 decoder for DM6467, how many reference frames are supported? We are using TI's H.264 decoder version 01.10.04.00. So far we have been using it to decode the Main Profile video with 1 reference frame. However, for the next generation of the s/w we are planning to...
