Display after deleting the decoding channel

yuxi

Firstly I create a decoding channel, and then delete the decoding channel, but the display is the last frame of the decoding channel, Now I want to display the blank frame after delete the decoding channel.

What needs to be modified in the swms?

Thanks.

There is another problem in the decoding.

the stream of 2048*1536(in resolution) is decoded by the DVR_RDK4.0, Firstly I create the channel, and then delete the channel, there are some logs:

[m3video] DEC : Delete CH0, Dummy Object queued !!!
[m3video] DEC : Delete CH0 Got the Dummy Object queued !!!
[m3video] 1107068: DECODE: CH0: Decoder flush needed (0)!!!
[m3video] 1107068: DECODE: CH0: Decoder Flushing !!!
[m3video] 1107069: DECODE: CH0: Decoder Flushing !!!
[m3video] 1107069: DECODE: CH0: Decoder Flushing !!!
[m3video] MemoryLeak:STAGE:0 HEAPNUM:0 ALLOC=4264 FREED=2368

but it runs OK. Then create the second decoding channel, and also delete it, there is no logs about the memory leak.

So I want to know what cause the memory leak in the first channel deleting.

Some memory is allocated when the very first decoder instance is created and is never released until shutdown of Video M3. You can ignore this.
