    Hi has any one started using the Platinum Codec released version 2.00.00.09 this month. i tried to port the H264 encoder replacing H264 encoder 1.10.00.08 in to my camera running on DM365. i am trying to find out the differences between the two using DM365 only ( Not DM368). i have not yet...

    Hi, I was wondering if the latest h.264 platinum encoder (v2.00.00.09) will be available on DM6467 ? If yes, when would it be available ? Thank you. Actually, i noticed strange results using the v1.20.02.00 when the video becomes more complex (i use a live cam shooting tree with leafs). The encoding...

    Bernard Vachon
    We've using dvsdk 2_10_01_18 on a dm368 for a video encoding application. In our application we create two encoders through VIDENC1_create. The first one is a MPEG4 encoder, the second is a H.264 encoder. Every once in a while, we get a kernel dump (see below) when creating the second encoder...

    When I use the h264enc concurrently with any of the mpeg2 or mpeg4 codecs, the dm365 will lock up after encoding a few frames. I've set h264DynParams.resetHDVICPeveryFrame = 1, and I'm using a mutex to protect access to the HDVICP. Using h264enc concurrently with other h264enc or h264dec instances...

    Hi I need to configure the frame rate in the SPS part of the header; for that I need access to the num_units_in_tick and time_scale VUI parameters. As far as I understand, it is not supported with this encoder (H264FHDVENC) on this platform (DM6467). Has someone different information? What...

  • Forum Post: How to improve H.264 performance (baseline profile, res=640x480)?

    Rohan Babtiwale
    Hi, I am using H.264 codec to encode video on DM368. I want constant bit rate of 512K maximum. The performance is okay with the still image but it degrades with the moving picture. There are blocks (pixalization) in the video stream. At 2M bit rate the performance is good. But I want a better picture...

    Hi, We're testing an in house encoder application that uses TI's H.264 Platinum encoder (v. 2.10.00.06) on a DM365 eval board. The example application that comes bundled with the encoder works, so I know the right pieces are in place in Linux. When we try to run our encoder application...

    Hi, I have tried changing these parameters and few other parameters. But there is no apparent change in video quality. I am only concerned about the pixel blocks in the image and picture clarity when there is motion. Can you give me overall back ground of how to remove pixalization at lower bit rates...

    Hello, I have installed the DVSDK which already provides several codecs. One of them is H264ENC (for OMAP3530) which is limited to maximum resolution 352x288 pixel. Thus I downloaded an alternate codec ( this one ) which targets C64x+ devices and provides much higher resolutions including full HD....
