Forum Post: H264 codec V2.0 Bit-Rate controls don’t enough to imprecise, DM365 SDK_2_10_01_18

Tanyu

Hi, At constant Bit-Rate, Bit-Rate controls don’t enough to imprecise. For example, suppose Current Bit-Rate is 2M, then I mask camera or detach video cable then attached, at this time real Bit-Rate change to 4M above. Few second, about 1-2 senond Bit-Rate recover normal. Best Regards ...

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?

Forum Post: VUI fixed_frame_rate_flag

MRI

When I set enabled VUI parameters the fixed_frame_rate_flag was not set to 1. Is there a way for me to set this flag other than the application providing the VUI for parameters? Also the declared frame rate is calculating to 15 frames per second.this is because the VUI parameters num_units_in_tick=2...

Hi! I have been working on a question in the linux forum - which I think about it now, was probably not the right spot but was anyhow being helped (which was nice). The TI employee came to the conclusion that my problem might actually be that the codec version I am using is returning a buffer handle...

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...
