The video decode sample illustrates decoding a single packetized video stream using FFMPEG demuxer, video parser, and rocDecoder to get the individual decoded frames in YUV format. 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 in a loop until all frames have been decoded.
## [Video decode batch sample](videoDecodeBatch)
This sample decodes multiple files using multiple threads, using the rocDecode library. The input is a directory of files and an input number of threads. The maximum number of threads is capped to 64.
If the number of files is higher than the number of threads requested by the user, the files are distributed to the threads in a round robin fashion.
If the number of files is lesser than the number of threads requested by the user, the number of threads created will be equal to the number of files.
## [Video decode memory](videoDecodeMem)
The video decode memory sample illustrates a way to pass the data chunk-by-chunk sequentially to the FFMPEG demuxer which is then decoded on AMD hardware using rocDecode library.
