out flush in gst-openmax

[bard]

Hello All,

I use gst-openmax0.10.1 to access qcom openmaxIL.
command "gst-launch filesrc location=/home/user/src.264 ! omx_h264dec ! fake
sink"

It turns out that Error from OpenMAX component
 

fill_this_buffer_proxy failure
ERROR: from element /GstPipeline:pipeline0/GstOmxH264Dec:omxh264dec0: GStreamer encountered a general stream error.
Additional debug info:
gstomx_base_filter.c(684): pad_chain (): /GstPipeline:pipeline0/GstOmxH264Dec:omxh264dec0:
Error from OpenMAX component
ERROR: pipeline doesn't want to preroll.
ERROR: Sending OMX_EventError to ClientSetting pipeline to NULL ...

What happens?

Your OMX H264 component raised an error. This doesn't look like a
gstreamer error, neither a gst-openmax one, this looks more like
something wrong in you OpenMAX implementation.

Thank you vmjl ,

I will figure out what's wrong in OpenMax.

So for gst-openmax , it doesn't need to modify in gstomx_base_filter.c pad_chain (). Right?

In theory, if your omx component follows "correctly" the spec, no
changes are needed in gst-openmax

I've been trying to use gst-openmax on android utilizing the qualcomm
snapdragon chip in HTC Passion/Google N1. I'm not sure if this is the
same omx core as referenced by Bard. Anyway, I've found that
gst-openmax has some shortcomings. First of all, responding to the
event OMX_EventPortSettingsChanged. So I'm not sure whether or not
gst-openmax "correctly" follows the OpenMAX IL spec. I'm not an expert
in this area so you probably want to wait for an answer from one of
the gst-openmax maintainers!?

I had the same problem yesterday. I feel that error reporting from OpenMAX is way to short.
My problew was the stream size (width or height not divisible over 16).
What parameters/pipeline is used to encode src.264? What is the size of the stream?

Thank you Haakon and Michael.
I don't know what paremeters/pipeline used , I downloaded it from website.

bard@ubuntu:~/vmshare/video_sample/omxtestprogram$ file src13_hrc7_525_420_2.264 
src13_hrc7_525_420_2.264: JVT NAL sequence, H.264 video, main @ L 30

By the way,I saw there is some configure needed from qcom's document about H264 NAL parser.
But In gst-openmax ,it doesn't deal with it ?
