VDEC Failure Due to Stream Size Verification Failure

Symptom

The error code HI_ERR_VDEC_ILLEGAL_PARAM is returned when hi_mpi_vdec_send_stream is called. The application log contains the error message stream len can't be zero!, as shown in the example below.

[Vdec]:vdec_check_send_stream [Line]:6563 pid 578 usr chn 64 device 0 chn 64 stream len can't be zero!

Possible Cause

The error stream len can't be zero! is reported in the log, which is intercepted by the VDEC code parameter verification. Check whether the input parameter stream->len or stream->addr is valid.

Solution

Check the value of stream->len in the code. If len is 0, modify the code logic to assign a value to the parameter.
