vdec2_process() function call hangs intermittently & indefinitely for h264

alok save

A problem we have encountered with decoder (h264) is that sometimes vdec2_process() hangs intermittently & sometimes indefinitely and never returns.
Also, sometimes vdec2_process() returns error like:

VIDDEC2_process() ret -1 inId 9 inUse 0 consumed 7
VIDDEC2_process() non-fatal error 0x0

We are not sure if such error conditions result in loss of buffers Which We have encountered before & raised another e2e query here.

Also, We have faced similar problems with h262 decoder as queried here.

The decoder version for h264 is:
Version 01.10.04

Can you please provide an explanation on the error handling that is expected for using vdec2_process().

Hi Alok,

I'm moving this to the Multimedia Forum since there have been no responses on the linux forum for your query. Maybe our Codec experts would be able to help you with your issue.

Alok,

Can you please provide and clarify the following,

1. Does the input erroneous.

2. What is the error code returned by decoder through "outargs->decodedBufs.extendedError"

3. Can you pls cross check whatever the buffer pointers sent to the process call are not NULL.

4. Pls mention the decoder build version (present in codec release notes)

Regards,

Mahantesh

Mahantesh,

1. Does the input erroneous.
The stream can be played correctly by vlc and other media players.
But playing it in the TI dcoder returns some non fatal extended error codes(mentioned in next answer).

2. What is the error code returned by decoder through "outargs->decodedBufs.extendedError"
The error codes which we get are:
0x2080 and 0xa41

3. Can you pls cross check whatever the buffer pointers sent to the process call are not NULL.
Yes, We have confirmed that they are not NULL.

4. Pls mention the decoder build version (present in codec release notes)

MPEG2(version.01.10.00.10) and H.264(version.01.10.04.00).
The Dvsdk version we are using is: dvsdk_3_10_00_16

Best Regards,

Alok

Alok,

Pls go through the codec user guide (table 4.3) for error codes 0x41 and 0x80 (LSB of 0x2080 and 0xa41).

Can you pls also share the stream you are using for this to reproduce at our end as well.

Regards,

Mahantesh
