Failed to allocate heap

[dpmcgarry]

After compiling on a pi 2 B+ i was able to run all unit tests. When i run the streamer (I exported variables for AWS Access / Secret keys and region) it gives the following error: INFO - Initializing curl.

createKinesisVideoClient(): Creating Kinesis Video Client heapInitialize(): Initializing native heap with limit size 536870912, spill ratio 0% and flags 0x00000001 heapInitialize(): Creating AIV heap. aivHeapInit(): Failed to allocate heap with limit size 536870912 heapInitialize(): Failed to initialize native heap. heapRelease(): Freeing native heap. Segmentation fault

@dpmcgarry, the sample application tries to allocate 512MB of storage which apparently is not available on your system. The code throws an exception which is not caught as it's a sample app and we haven't yet hardened it for these types of failures. Generally, in a real-life application, one would try to determine how much storage would be needed and will handle the failures gracefully.

In this case I would recommend changing the allocation from 512MB to a much smaller (single stream PI with limited bandwidth and good networking would require far less storage).

instead of device_info.storageInfo.storageSize = 512 1024 1024;

please specify device_info.storageInfo.storageSize = 128 1024 1024;

We will, however, take a note and update the sample application to have more dynamic allocation. We will also document the best practice on determining how much storage one would need and how to configure the StreamDefinition better for your needs.

Hmmm that doesn't make sense...I have 24G free for my root partition: pi@pi-dev:~/amazon-kinesis-video-streams-producer-sdk-cpp/kinesis-video-native-build $ df -h

The available storage is on eMMC - read file system. The current implementations of the heap are all RAM based. We will be adding a hybrid storage which would utilize the file-backed storage as a spill-over later.

This said, for your PI you will hardly need that large of the storage anyway.

Ok now i am getting an error stating unable to set the pipeline to the playing state:

Disregard. Was able to get it working by running modprobe

I had the same issue on Raspberry Pi 3B Changing from device_info.storageInfo.storageSize = 512 * 1024 * 1024; to device_info.storageInfo.storageSize = 128 * 1024 * 1024 in kinesis-video-gst-demo/kinesis_video_gstreamer_sample_app.cpp line 126 worked for me.
