This is a system command.
Ffprobe-v error-print_format json-show_format-analyzeduration 10000000-I async: https://083000.avi
In the window environment, a single ok is executed, and the program loop executes ok. In the linux environment, the ok is executed in the terminal, the single execution in the program fails, and the loop execution also fails. The following error is reported:
Argument 'async: https://083000.avi' provided as input filename, but' 'was already specified. The reason is unknown.
Solution: modify the execution mode of the command in java code and replace the string command with split execution in the form of an array. The solution can be solved as follows
RuntimeUtil.execForStr ("ffprobe", "- v", "error", "- print_format", "json", "- show_format", "- analyzeduration", "10000000", "- I", String.format ("async: https://xxx/%s", key)
RuntimeUtil: utility class in HuTool, which can introduce corresponding dependencies
