This article mainly introduces "what problems do you need to pay attention to when executing ffprobe on the Runtime command line". In daily operation, I believe that many people have doubts about what problems they need to pay attention to when executing ffprobe on the Runtime command line. The editor consulted all kinds of materials and sorted out simple and easy-to-use methods of operation. I hope it will be helpful to answer the doubts of "what problems do you need to pay attention to when implementing ffprobe on the command line of Runtime?" Next, please follow the editor to study!

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
