    command arguments as a concatenated string
  - getAllLogs
```
List<Log> getAllLogs(int waitTimeout)
```
    Returns all log entries generated for this session. If there are asynchronous messages that are not delivered yet, this method waits for them until the given timeout.
    
    参数:
    
    waitTimeout - wait timeout for asynchronous messages in milliseconds
    
    返回:
    
    list of log entries generated for this session
  - getAllLogs
```
List<Log> getAllLogs()
```
    Returns all log entries generated for this session. If there are asynchronous messages that are not delivered yet, this method waits for them.
    
    返回:
    
    list of log entries generated for this session
  - getLogs
```
List<Log> getLogs()
```
    Returns all log entries delivered for this session. Note that if there are asynchronous log messages that are not delivered yet, this method will not wait for them and will return immediately.
    
    返回:
    
    list of log entries received for this session
  - getAllLogsAsString
```
String getAllLogsAsString(int waitTimeout)
```
    Returns all log entries generated for this session as a concatenated string. If there are asynchronous messages that are not delivered yet, this method waits for them until the given timeout.

    all log entries generated for this session as a concatenated string
  - getAllLogsAsString
```
String getAllLogsAsString()
```
    Returns all log entries generated for this session as a concatenated string. If there are asynchronous messages that are not delivered yet, this method waits for them.

    all log entries generated for this session as a concatenated string
  - getLogsAsString
```
String getLogsAsString()

    state of the session
  - getReturnCode
```
ReturnCode getReturnCode()
```
    Returns the return code for this session. Note that return code is only set for sessions that end with COMPLETED state. If a session is not started, still running or failed then this method returns null.
    
    返回:
    
    the return code for this session if the session is COMPLETED, null if session is not started, still running or failed
  - getFailStackTrace
```
String getFailStackTrace()
```
    Returns the stack trace of the exception received while executing this session.
    The stack trace is only set for sessions that end with FAILED state. For sessions that has COMPLETED state this method returns null.
    
    返回:
    
    stack trace of the exception received while executing this session, null if session is not started, still running or completed
  - getLogRedirectionStrategy
```
LogRedirectionStrategy getLogRedirectionStrategy()
```
    Returns session specific log redirection strategy.
    
    返回:
    
    session specific log redirection strategy
  - thereAreAsynchronousMessagesInTransmit
```
boolean thereAreAsynchronousMessagesInTransmit()
```
    Returns whether there are still asynchronous messages being transmitted for this session or not.
    
    返回:
    
    true if there are still asynchronous messages being transmitted, false otherwise
  - addLog
```
void addLog(Log log)
```
    Adds a new log entry for this session.
    It is invoked internally by FFmpegKit library methods. Must not be used by user applications.
    
    参数:
    
    log - log entry
  - getFuture
```
Future<?> getFuture()
```
    Returns the future created for this session, if it is executed asynchronously.
    
    返回:
    
    future that runs this session asynchronously
  - isFFmpeg
```
boolean isFFmpeg()
```
    Returns whether it is an FFmpeg session or not.
    
    返回:
    
    true if it is an FFmpeg session, false otherwise
  - isFFprobe
```
boolean isFFprobe()
```
