h.264 platinum encoder & dm6467

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 process returns a video frame type 3 (IDR) and size 0 while i asked for a P-frame and after that the encoder task hangs up.

    Ronan,

    Is your query regarding the DM6467 codecs or the DM365 codecs? I am asking this because the Platinum series of codecs are developed for DM365 only, not DM6467.

    Hi Kapil,

    My query concerns DM6467. I have read that 720p & 1080i/p version would be merged in a single version soon. The issue i have noticed with v1.20.00.20 happens after a call to XDM_SETPARAMS. I try to change the bitrate dynamically before first frame (I-picture) of GOP and sometimes the following P-picture are skipped and encoding task hangs up. I do not see what i have missed. May be in my configuration ? Or may be a bitrate regulation problem ?

    Thank you.

    Ronan,

    I wanted to seek some clarification before I can dig further into your usage scenario.

    1. What do you mean when you say, "I asked for a P frame" (your initial post on this topic) - "The encoding process returns a video frame type 3 (IDR) and size 0 while i asked for a P-frame and after that the encoder task hangs up?

    2. In a subsequent post, you have mentioned that you call Control with SETPARAMS to change the bit-rate dynamically before the first I picture. Is this first I picture of the stream or is that in between you are trying to change the bit rate and then forcing an I_FRAME out of the encoder? Can you elaborate on the exact sequence of execution?

    Regards,
