[xine-devel] Need help with demuxer plugin

[Martin E. <em...@em...>]

Hi!

I am implementing a xine demuxer plugin to play back MPEG video/audio 
received from a C++ application. Sending the data to xine works already,
but when I start playback, I see only the keyframes (ca. 1-2 per second, 
the rest being dropped/discarded), and I have no audio .

I see lots of these messages:

video_out: throwing away image with pts 2852979 because it's too old 
(diff : 88598).

It is no CPU issue, load is fairly low. The data is correct; if I dump 
the ES to separate files I can play them back later just fine. The data 
is coming in at a steady pace, so the demuxer should not be starving, 
either. I probably messed up the buffer decoder_flags or something like 
that.

On each call to ..._send_chunk, I put() one Elementary Stream packet 
retrieved from a PES packet to the fifo, using the PES packet's PTS. If 
the frame has to be split among multiple buf_element_t, I set 
BUF_FLAG_FRAME_END only for the last part.

I tried to do basically the same things as other demuxer plugins (eg 
demux_ts.c), but I am missing something.

Thanks for any Hints!

Ciao
