  • Forum Post: OSD blending difference when using v4l2sink vs omx_ctrl/omx_videosink

    Daniel70334
    We have to support custom HDMI output rates for a video decoder application on our 814x/816x app. The gstreamer lines which use the omx_ctrl/omx_videosink combination all have a fixed display-mode=OMX_DC_MODE_*, which seem unflexable. So I changed the the rc5.d symlink to load the v4l2 firmware, by pointing...

  • Forum Post: RE: HDMI HPD query and state change notification

    Daniel70334
    Hello Hardik, Your proposed solution sounds good, especially since it also recognizes that possibility of application control over HDMI/DVI mode, and application analysis of EDID (for adjusting output resolution to the best timing, etc.). So many thanks. While I'm fine with a blocking ioctl,...

    hi, Ken We have the same problem! We use 814x evm. We are also want to achieve the mpeg ts with h.264 video from RTP stream. But it's decode not smoothly. Sometimes the frames decode faster, sometimes stop. Maybe some comment parameters setup is error. We find the gstreamer also can not decode...

  • Forum Post: Changing the output to 720p/23.98 or 720p/24 fails

    Daniel70334
    We are developing a product using DM816x and DM814x EVMs that needs to support a variety of output resolutions. Running either of the following procedures to change the output rate from 1080p to 720p/23.98 or 720p/24 results in no video output on ti-ezsdk_dm816x-evm_5_04_00_11. # Change output to 720p...

  • Forum Post: HDMI HPD query and state change notification

    Daniel70334
    We need to know when the 816x/814x EVM output is plugged into an HDMI sink, to read and process the EDID, and determine HDMI vs DVI. Similarly, we also need to know if the HPD is pulsed (signaling an EDID change), so periodic polling with ioctl(TI81XXHDMI_GET_STATUS) seems ill-advised. Is there a way...

    Hi, We use C6A8168 CPU now. We make boards with C6A8168. Not DM8168. I know that DM816x is pin compatible with C6A816x. But I have a problem. HDVICP2 is loading when U-boot file call kernel image. DM816x hasn't errors because it has HDVICP2. But C6A816x hasn't HDVICP2, so it has...

    We have observed a problem with both DM816x EVM and DM814x EVM, with EZSDK 5_04_00_11. After changing the kernel configuration to enable HDMI audio output, we are able to hear audio on the HDMI output when running at 1080p-60 (the SDK's default output setting). But if we change the output to 480p...
