The below table gives information about the features supported in this design.
Pipeline | Input Source | Output Type | ALSA Srivers | Resolution | Audio Codec Type | Audio Configuration | Video Codec | Deliverables |
|---|---|---|---|---|---|---|---|---|
Record/Stream-Out pipeline | SDI-Rx | File Sink/ Stream-Out | SDI-Rx ALSA drivers | 4K/1080p | AAC | 2 channel @ 48 kHz | HEVC/AVC | SDI-Rx Audio encode with soft codec and video with VCU and store it in a container format. |
Playback pipeline | File Source/ Stream-In | SDI-Tx | SDI-Tx ALSA drivers | 4K/1080p | AAC | 2 channel @ 48 kHz | HEVC/AVC | Playback of the local-file/stream-in with video decoded using VCU and Audio using GStreamer soft codec. |
Capture → Display | SDI-Rx | SDI-Tx | SDI-Rx ALSA drivers and SDI-Tx ALSA drivers | 4K/1080p | NA | 2 channel @ 48 kHz | HEVC/AVC | SDI-Rx Audio /Video pass to SDI-Tx without VCU/Audio-Codec. |
Capture → Encode → Decode → Display | SDI-Rx | SDI-Tx | SDI-Rx ALSA drivers and SDI-Tx ALSA drivers | 4K/1080p | NA | 2 channel @ 48 kHz | HEVC/AVC | SDI-Rx raw audio and video with VCU encoder and decode to achieve AV sync. |
The below figure shows the SDI Video Capture and SDI Display with Audio design hardware block diagram.
