[Docker] too many thread_release_buffer calls!

[tashrifbillah]

Hi, I tried the following command inside your docker container. It completes without any error but with an empty input_aligned directory:

openface-build/build/bin/FaceLandmarkVidMulti -f input.mp4 -out_dir output/

...
Attempting to read from file: input.mp4
Device or file opened

And then input_aligned directory is empty:

output/
├── input_aligned
├── input.csv
├── input.hog
└── input_of_details.txt

Did anyone see this log before:

too many thread_release_buffer calls!

I've seen this error before and it does not really cause any issues (besides the error messages), see https://stackoverflow.com/questions/29995917/opencv-error-mpeg4-0x7ffe33cb3e60-too-many-thread-release-buffer-calls

Hmm but why is the input_aligned directory empty? I set up display parameters properly that the tracking video pops up during tests.
