Video decode sample
The VideoToSequence sample illustrates decoding a single packetized video stream using FFMPEG demuxer and splitting it into multiple video sequences. This uses seek functionality to seek to a random position and extract a batch of video sequences in YUV format with step and stride. This sample can be configured with a device ID and optionally able to dump the output to a file. This sample uses the high-level RocVideoDecoder class which connects both the video parser and Rocdecoder. This process repeats until a batch of sequences are extracted or EOS is reached.
Prerequisites:
-
Install rocDecode
-
- On
Ubuntu
sudo apt install libavcodec-dev libavformat-dev libavutil-dev- On
RHEL/SLES- install ffmpeg development packages manually or use rocDecode-setup.py script
- On
