* Fix a segmentation fault on some samples when the memory type is 3 (OUT_SURFACE_MEM_NOT_MAPPED) and attempting to save the output (which is not supported)
* update the videoDecodeMultiFiles sample
* update the readme for videoDecodeMultiFiles
* add comments
* use OUT_SURFACE_MEM_NOT_MAPPED instead of integer number 3

Video decode sample
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.
Prerequisites:
-
Install rocDecode
-
- On
Ubuntu
sudo apt install ffmpeg libavcodec-dev libavformat-dev libavutil-dev- On
RHEL/SLES- install ffmpeg development packages manually or use rocDecode-setup.py script
- On
Build
mkdir video_decode_sample && cd video_decode_sample
cmake ../
make -j
Run
./videodecode -i <input video file [required]>
-o <output path to save decoded YUV frames [optional]>
-d <GPU device ID - 0:device 0 / 1:device 1/ ... [optional - default:0]>
-z <force_zero_latency - Decoded frames will be flushed out for display immediately [optional]>
-sei <extract SEI messages [optional]>
