amr-wb seek problem
Locked
 
|
Hi
I am writing amr-wb player with gstreamer on Marvell pxa310. When I seek to a position by time format, there is a long time blocking (10 sec or even to 1 min), and there is no voice during the block, then an EOS message was emitted, but the position I seeked is far away to the end of the file. Bytes format has the same problem! here is my seek code: breslt = gst_element_seek(pipeline, 1.0, GST_FORMAT_BYTES, GST_SEEK_FLAG_FLUSH,//|GST_SEEK_FLAG_KEY_UNIT|GST_SEEK_FLAG_SEGMENT, GST_SEEK_TYPE_SET, bytePos,//GST_SECOND*nForw*count, GST_SEEK_TYPE_NONE, GST_CLOCK_TIME_NONE ); I use gstreamer-0.10.29 and gst-plugins-ugly-0.10.15's amrwbdec, gst-plugins-bad-0.10.13's amrparse. like this: gst-launch filesrc location=abc.amr ! amrparse ! amrwbdec ! alsasink And the codec is opencore-amr-0.1.2 Could any body help? |

It seems amrwbdec does not handle src pad event (seek ) and thats why there is a blocking. There is a lack of implementation of src event handling thats why kept in gst-plugins-ugly.

Thanks for everyone's help!
I have got the issue fixed, it's the amrwbdec: just add one line in the amrwbdec.c of
gst-plugins-ugly-0.10.16.
288: if (!block || gst_adapter_available (amrwbdec->adapter) < block)
+ {
+ gst_adapter_clear (amrwbdec->adapter);
break;
+ }
Because when there are incorrect data, if you don't clear it, the next checking is still incorrect. On 2011年01月10日 21:00, sudarshan bisht wrote:
