# Transform and Transcode use cases

Source: [https://docs.qualcomm.com/doc/80-70014-50/topic/transform-and-transcode-use-cases.html](https://docs.qualcomm.com/doc/80-70014-50/topic/transform-and-transcode-use-cases.html)

The transcoding use cases demonstrate converting or transforming the video streams
        from one format to another.

Before you begin executing the use cases, ensure that you complete the preconditions
            mentioned in [Multimedia use cases](https://docs.qualcomm.com/doc/80-70014-50/topic/multimedia-use-cases.html).

- **[1080p to 1080p – rotate (90/180/270)](https://docs.qualcomm.com/doc/80-70014-50/topic/1080p-to-1080p-rotate-90-180-270.html)**  

The pipeline demonstrates rotation of scenes from a camera by 180 degrees and         displayed on a local display device.
- **[Offline 1080p stream to 1080p – rotate (90/180/270)](https://docs.qualcomm.com/doc/80-70014-50/topic/offline-1080p-stream-to-1080p-rotate-90-180-270.html)**  

The pipeline shows the rotation of scenes from a file source by 180 degrees and         displayed on a local display device.
- **[4K to 1080p – rotate (90/180/270) and downscale at same time](https://docs.qualcomm.com/doc/80-70014-50/topic/4k-to-1080p-rotate-90-180-270-and-downscale-at-same-time.html)**  

The pipeline shows the video stream of 4k resolution from a camera being downscaled         to 1080p and rotated by 180 degrees, and then displayed on a local display         device.
- **[Offline 4K to 1080p – rotate (90/180/270) and downscale at same time](https://docs.qualcomm.com/doc/80-70014-50/topic/offline-4k-to-1080p-rotate-90-180-270-and-downscale-at-same-time.html)**  

The pipeline shows a video stream of 4k resolution from a file source being         downscaled to 1080p and rotated by 180 degrees, and then displayed on a local display         device.
- **[1080p to 1080p – flip horizontal/vertical flip](https://docs.qualcomm.com/doc/80-70014-50/topic/1080p-to-1080p-flip-horizontal-vertical-flip.html)**  

The pipeline shows how to flip scenes horizontally.
- **[Offline 1080p to 1080p – flip horizontal/vertical flip](https://docs.qualcomm.com/doc/80-70014-50/topic/offline-1080p-to-1080p-flip-horizontal-vertical-flip.html)**  

The pipeline shows how to flip scenes horizontally.
- **[4K to 1080p – flip horizontal/vertical flip and downscale at same time](https://docs.qualcomm.com/doc/80-70014-50/topic/4k-to-1080p-flip-horizontal-vertical-flip-and-downscale-at-same-time.html)**  

The pipeline shows how to downscale a 4k resolution video stream to 1080p and flip         the scenes horizontally.
- **[4K – Downscale to 1080p—encode to AVC MP4](https://docs.qualcomm.com/doc/80-70014-50/topic/4k-downscale-to-1080p-encode-to-avc-mp4-mux.html)**  

The pipeline captures 4k resolution video stream, sends one copy of it to encoder and         MP4 multiplexer to store in a file. It sends another copy to qtivtransform to downscale the         stream 1080p resolution before encoding and multiplexing to a MP4 file on         device.
