[gst-devel] Problems With Feeding gstpipeline with gstapp spurce

[Ankur Sharma]

Hello,

I am facing a problem while feeding a gstreamer pipeline using gstappsrc. The details are:


 1.  I create gstbuffers and sub-buffers to collect TS packets, read from another application (through a Shared Memory) and then I push these buffers to the gstappsrc element.
 2.  My pipeline consists of ffmpegdec and an imagesink.
 3.  I calculate the buffer_timestamps using PTS values and stamp the outgoing buffers.

The strange problem I face is that if I feed PES packet with a one byte wrong start_offset, then the pipeline throws error messages (using GST_DEBUG) but it PLAYS the video. If however, I give the correct PES packets start, the pipeline does not throw any errors, but cant play the file.

It would be great if some expert could give me a hint based on this observation. How should my external application sync with the "state" of the gstreamer pipeline and feed it with data buffers.

Regards
Ankur
