[Bug] Use of decord to read videos hangs without any error/warn message

Use of [decord](https://github.com/dmlc/decord) to read videos hangs without any error/warn message.

This can be frustrating especially in cases of using `decord` in a broader context (e.g. inference of `Qwen3-Omni-30B-A3B-Instruct`) where one processes millions of video files.

One can find a relevant report here https://github.com/QwenLM/Qwen3-VL/issues/736 and can reproduce `decord` hanging using this example https://github.com/vipcxj/decord_hang .
