Problem in using ffdec_mp3 to decode live streaming
Locked
 
|
Hi All,
I m facing problem in decoding mp3 using ffdec_mp3 when i m capturing audio and listening to it, but i m able to hear when i am using mad decoder with the below command, but there are some glitches when i replace mad with ffdec_mp3. But i m able to playback the saved file using ffplay which i have captured. So i guess ffdec is not capable of decoding the live streaming data, i need some help to solve this bug. Any help will be greatly appreciated. Thanks in advance. sudo gst-launch gstrtpbin name=rtpbin alsasrc ! audioconvert ! audioresample ! lamemp3enc ! rtpmpapay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink port=5002 host=127.0.0.1 rtpbin.send_rtcp_src_0 ! udpsink port=5003 host=127.0.0.1 sync=false async=false udpsrc port=5007 ! rtpbin.recv_rtcp_sink_0 sudo gst-launch gstrtpbin name=rtpbin udpsrc caps="application/x-rtp,media=(string)audio,clock-rate=(int)90000,encoding-name=(string)MPA,pt=(int)96" port=5002 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtpmpadepay ! mp3parse ! mad ! audioconvert ! volume volume=10 ! audioresample quality=10 ! alsasink udpsrc port=5003 ! rtpbin.recv_rtcp_sink_0 rtpbin.send_rtcp_src_0 ! udpsink port=5007 host=127.0.0.1 sync=false async=false |

Have you looked at the debug logs? (You could start with level 3) Did you find anything out of place there? May be a warning or something?
Also, I suggest you take logs for both the decoders and compare them. You should be able to spot the problem.

Please let me know if there r any, any help will be greatly appreciated. Thanks in advance. sudo gst-launch gstrtpbin name=rtpbin alsasrc ! audioconvert ! audioresample ! lamemp3enc ! rtpmpapay ! rtpbin.send_rtp_sink_0 rtpbin.send_rtp_src_0 ! udpsink port=5002 host=127.0.0.1 rtpbin.send_rtcp_src_0 ! udpsink port=5003 host=127.0.0.1 sync=false async=false udpsrc port=5007 ! rtpbin.recv_rtcp_sink_0 sudo gst-launch gstrtpbin name=rtpbin udpsrc caps="application/x-rtp,media=(string)audio,clock-rate=(int)90000,encoding-name=(string)MPA,pt=(int)96" port=5002 ! rtpbin.recv_rtp_sink_0 rtpbin. ! rtpmpadepay ! mp3parse ! mad ! audioconvert ! volume volume=10 ! audioresample quality=10 ! alsasink udpsrc port=5003 ! rtpbin.recv_rtcp_sink_0 rtpbin.send_rtcp_src_0 ! udpsink port=5007 host=127.0.0.1 sync=false async=false The above command works fine, but when i replace with ffdec_mp3 there is lot of noice, how could i solve this or is there any other LGPL decoders which would do the needful.

Maybe you could try gst-av[1], it can use FFmpeg (libavcodec) just like gst-ffmpeg, but it's much simpler. It's definitely not production-ready, but being only 455 lines of code I think you might be able to find the issues ;) [1] https://github.com/felipec/gst-av -- Felipe Contreras ------------------------------------------------------------------------------ Protect Your Site and Customers from Malware Attacks Learn about various malware tactics and how to avoid them.
