Buffering issue with Exoplayer












0















I'm trying to set a streaming app using exoplayer, but there's something I don't get about buffering.



It is supposed to try to ensure that the buffer size is always between DEFAULT_MIN_BUFFER_MS and DEFAULT_MAX_BUFFER_MS. I can also set a DEFAULT_BUFFER_FOR_PLAYBACK_MS, which sets the buffer size required for starting to play the stream.



But whenever I set the DEFAULT_BUFFER_FOR_PLAYBACK_MS lower than the DEFAULT_MIN_BUFFER_MS, it seems that DEFAULT_MIN_BUFFER_MS takes the value of the DEFAULT_BUFFER_FOR_PLAYBACK_MS.



For example : if I set DEFAULT_MIN_BUFFER_MS to 10000, DEFAULT_MAX_BUFFER_MS to 20000 & DEFAULT_BUFFER_FOR_PLAYBACK_MS to 5000, then my buffer size will stay between 5 seconds and 20 seconds instead of 10 to 20. Is this expected or am I missing something in the way I set my player ?



Here's a sample of my code, feel free to ask if you need more :



public static final int DEFAULT_MIN_BUFFER_MS = 10000;

public static final int DEFAULT_MAX_BUFFER_MS = 20000;

public static final int DEFAULT_BUFFER_FOR_PLAYBACK_MS = 5000;

public static final int DEFAULT_BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS = 5000;



DefaultLoadControl loadControl = new DefaultLoadControl.Builder()

               .setAllocator(new DefaultAllocator(true, C.DEFAULT_BUFFER_SEGMENT_SIZE))

                .setBufferDurationsMs(DEFAULT_MIN_BUFFER_MS,

                        DEFAULT_MAX_BUFFER_MS, DEFAULT_BUFFER_FOR_PLAYBACK_MS, DEFAULT_BUFFER_FOR_PLAYBACK_AFTER_REBUFFER_MS)

                .setPrioritizeTimeOverSizeThresholds(true)

                .createDefaultLoadControl();



player = newSimpleInstance(this,defaultRenderersFactory, trackSelector, loadControl, null, bandwidthMeter);

          0 I am trying to run a scheduled task with User Group (not a single user). This is working fine when I in the field "when running a task, use the following user account:" insert BUILTIN User Group (for example: Administrators or Users). But when I try it with the created Local User Group (example: TestGroup) it is not working. The Users in the TestGroup are the same as in the Administrators group. What could be the problem?
