  • 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...

  • Forum Post: dm368 1080p h264 single stream not able to reach 30fps

    william wang63854
    Hi I'm encountering some frame rate issue for dm368 1080p h264 single stream. 1: there is only H264 single stream, no MJPEG, no CVBS. VIDENC1_process() will consum 32/33 ms. so it's very tough to output stream 30fps. is the consum time statistic correct on DM368 board? my DVSDK: dvsdk_3_10_00_19...

    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...

    It looks like there is some misunderstanding on our correspondences. All the files I uploaded are to show there is no problem in mp4 packing All the files were created with the same parser. So, it is not mp4 packing related problem. Maybe it is related to AAC-LC bitstream (of DM368 AAC encoder...

    Thanks for your kind reply. Your sample file sounds fine. BUT, I’m somewhat disappointed that it’s not 8kHz audio. Is there any special reason that you tested with 32kHz? As you know, IPNC SDK dose support only 8kHz and 16kHz, NOT 32kHz. If we try to forcefully set 32kHz, an error comes out...

    Hi, I am working on a DM368 platform and encoding H.264 at 1080P / 30 / 6Mbps / CBR. The encoded NAL stream is placed in an MPEG2 TS and sent over the network to a broadcast decoder. The decoder is very picky about the data being exact CBR. Usually we could insert NULL packets into the stream to make...

    Hi Veeranna: Veeranna Hanchinal With High Quality mode also you should get 3D1_h264+1D1MPEG4. Tracy>> You mean we can got 30FPS with 3xD1 H264 + 1xD1MPEG4 on DM365/DM368? I have tried on both DM365 and DM368, the real frame rate is about 22~24FPS.
