RTOS/DRA74: playback support?

Widic Jane
Expert 1800 points

Part Number: DRA74

Tool/software: TI-RTOS

I use encode link to encode video(MP4), Now I want to playback the video(MP4).

GST Video encode and decode support on VSDK Linux (To support CBB and other video playback applications).

is Gst support when the encode exist?

    Hi Widic,
    encodelink and gstreamer require different firmwares to access IVA and they are mutually exclusive. encodeLink uses a firmware from vision-sdk and for gstreamer it is ipumm firmware from PSDKLA.

    So gst-playback support with encodeLink is not possible. You may think of a usecase of gst-encode instead of encodeLink using ipumm firmware.

    Thanks

    Thanks,
    So could you guide me to complete it (gst-encode)?

    can you give me some suggestions?

    Hi Widic,
    You can first start with a gst-pipeline
    gst-launch-1.0 videotestsrc num-buffers=100 ! 'video/x-raw, format=(string)NV12, width=(int)640, height=(int)480' ! ducatih264enc ! h264parse ! mp4mux ! filesink location=encoded.mp4

    make sure ipumm firmware is loaded and corresponding changes done in memory map to use this firmware. Refer vision-sdk userGuide(IPUMM=yes).

    If your usecase is to encode a VIP captured buffer, VIP is configured currently from M4 and it is not available for A15, so you can not use v4l2src to capture from A15. so this usecase also doesn't seem to work in that case.
