Hello<br>
<br>
I am trying to play the audio and the video from a mp4 file. If I run
the following line:<br>
<br>
gst-launch -vvvvv --gst-debug-level=2 playbin
uri=<a class="moz-txt-link-freetext" href="file:///">file:///</a><path_to_mp4_file><br>
<br>
Then it plays the file's audio. I'm not putting the video anywhere, so
I can't see if it is playing or not, but I assume it is based on the
debug output. <br>
<br>
If I do the following line:<br>
<br>
gst-launch -vvv --gst-debug-level=2 filesrc
location=<path_to_mp4_file> ! decodebin2 name=decoder decoder. !
audioconvert ! audioresample ! osssink decoder. ! ffmpegcolorspace !
xvimagesink<br>
<br>
It hangs at:<br>
<br>
Setting pipeline to PAUSED ..<br>
/GstPipeline:pipeline0/GstDecodeBin2:decoder/GstTypeFindElement:typefind.GstPad:src:
caps = audio/x-m4a<br>
Pipeline is PREROLLING ...<br>
<audio debug output snipped><br>
<br>
I need to open this file in C code, and grab access to the buffers. I
was planning on using appsink to do it, but any time I pass in a video
sink to the pipeline, it just hangs, never playing the audio, or moving
forward. As I said, I need access to the video buffer, so either I
need a way to grab it from the pipeline created from gst_parse_launch,
or I was thinking that if I set up the pipeline myself, I could use a
handoff signal on the last video sink, or mayber use the appsink
methods. <br>
<br>
I have a feeling that I am missing something simple, and was hoping
someone could point that out. <br>
<br>
Thanks,<br>
Rodney<br>
