  • Forum Post: DM6467 periodical IDR frame generation possible bug

    Nir Aloni
    I followed TI's instructions for forcing IDR frames on the DM6467 h.264 encoder CODEC and it works fine and I can force IDR frame every desired number of frames. After running my application for a long time I start to see pixelization artifacts every several seconds (which later found to be the...

  • Forum Post: Framerate dropped suddenly when running encode demo on dm6467

    zhifei zhang
    Hi, When I run encode demo on dm6467, I find a strange problem. There is a sudden drop of framerate in the process of encoding. The output information is as follow: # ./encode -v 1.264 -a 1.aac Encode demo started ... Encode demo ARM Load: 9% DSP Load: 70% Display Type: 720P 50Hz Video...

  • Forum Post: Frame Rate (H264 Encoder 1.20.02.00)

    BrandyJ
    Hello, I am trying to set the frame rate and the bit rate in my encoder instance. I would like the Frame Rate to 8 frames per second and the CBR to 800000bps. I set static parameters to: params.rateControlPreset = IVIDEO_LOW_DELAY; params.maxBitRate = 800000; params.inputChromaFormat = XDM_YUV_420SP;...

  • Forum Post: DM6467 H.264 Encoder Latency

    babs76
    Can someone tell me (or point me to a document) what the latency of the H.264 encoder is? I understand that there is algorithm latency (e.g. the algorithm takes 14.4 ms until it spits out an answer), but is there multiframe latency associated with the encoder? Does the encoder need multiple frames buffered...

    Nir Aloni
    I am currently using DM6467 with the h.264 decode codec version 1.10. I am having a problem where after some time decoding a stream where the codec outputs 1 display buffer for each call to the DMAI function 'Vdec2_getDisplayBuf' , suddenly the codec outputs 8 display buffers at once and after...

  • 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...

    xiaoyang xie
    Hi, experts Our product development has completed with the H264&mpeg2 part. And now we need to add mpeg4 decode support. I verify the problem by running the dvtb. Also, I modify the decode demo in the dvsdk_demos_3_10_00_16 to support mpeg4, but it fails at another step(D1 is OK). So I think...
