I was following the guide here How to play a PCM data array with GStreamer step by step (Florian Zwoch's solution). However, there is no sound output from gstreamer.
I am using windows and installed gstreamer through msys2 along with various gstreamer plugins. I can compile and run gstreamer's basic tutorial (https://gstreamer.freedesktop.org/documentation/tutorials/basic/hello-world.html?gi-language=c) so I believe this is not a Gstreamer installation problem.
What should I do to solve the problem?
Update1: using Sudhir Kesti's suggestion gst-launch-1.0.exe filesrc location=D:\Work\command-post\mix_1.pcm ! rawaudioparse num-channels=1 sample-rate=8000 pcm-format=GST_AUDIO_FORMAT_S16LE ! audioconvert ! audioresample ! autoaudiosink --gst-debug=2,I am able to play. However, I am still unable to query the duration of the pipeline or use gst_element_seek_simple. How to query the duration or seek the position of the pipeline?
You need rawaudioparse to bundle audiosamples into frames. Add audioconvert and audioresample to convert pcm to the desired format. Set channel, format, and rate as per the pcm data.
gst-launch-1.0.exe filesrc location=D:\Work\command-post\mix_1.pcm ! rawaudioparse num-channels=1 sample-rate=8000 pcm-format=GST_AUDIO_FORMAT_S16LE ! audioconvert ! audioresample ! autoaudiosink --gst-debug=2
Use gst_parse_launch() for sample application.
