gstreamer caps negotiation fail when using USB sound card
Locked
 
|
hi all,
When I try to play wav audio to usb sound card, it is fail, the command I used : gst-launch-0.10 -v filesrc location=/bin/audio_src_48k_le.wav ! wavparse ! audioconvert !audio/x-raw-int, rate=48000,channels=2,width=16,endianness=4321 ! alsasink device="hw:0,0" the error is : streaming task paused, reason not-linked (-1) Below is the log I captured from debug level 5, does anyone have idea how to fix the issue? ================================================================================== 0:32:12.150000000 1142 0x4234f0 LOG default gsttypefindhelper.c:550:gst_type_find_help

hi Stefan,
Could you kindly give some hints about the nego fail issue? the log below I summary the fail progress, I was confused about "caps are notcompatible". it obviously has got "wavparse_src" and "audioconvert sink" . And I also trying to link wavparse0:src and audioconvert0:sink. Why it get incompatible pads during negotiation? I just set many "get pad caps", it is not clear about what happen in negotiation progess. ======================================================== # gst-launch-0.10 --gst-debug-no-color

Hi, Stefan,
I. What do you mean about the method of dump log? convert the generated dot files: dot -Tpng xxx.dot -ograph.png ====>how to convert the log file? what is dot-Tpng? Does it convert log to a picture? II. Could you explain more detail about the format? When I use aplay, it is OK. the parameter that dump from aplay: # aplay -v -f S16_LE -c 2 -r 48000 -D default /bin/audio_src_48k_le.wav Hardware PCM card 0 'USB AUDIO ' device 0 subdevice 0 Its setup is: stream : PLAYBACK access : RW_INTERLEAVED format : S16_LE subformat : STD channels : 2 rate : 48000 exact rate : 48000 (48000/1) msbits : 16 buffer_size : 24000 period_size : 6000 period_time : 125000 tstamp_mode : NONE period_step : 1 avail_min : 6000 period_event : 0 start_threshold : 24000 stop_threshold : 24000 silence_threshold: 0 silence_size : 0 boundary : 1572864000 appl_ptr : 0 hw_ptr : 0 # 2012/8/2 Stefan Sauer <[hidden email]>: > On 07/31/2012 02:03 PM, Soho Soho123 wrote: >> hi all, >> >> When I try to play wav audio to usb sound card, >> it is fail, >> the command I used : >> gst-launch-0.10 -v filesrc location=/bin/audio_src_48k_le.wav ! >> wavparse ! audioconvert !audio/x-raw-int, >> rate=48000,channels=2,width=16,endianness=4321 ! alsasink >> device="hw:0,0" >> >> the error is : >> streaming task paused, reason not-linked (-1) >> Below is the log I captured from debug level 5, >> does anyone have idea how to fix the issue? > The log is unreadable in this form.

Hi all, I am planning to develop a pipeline for streaming session switch. It is for SIP devices and I have a proxy that handles streaming requests (an intermediary b/n the client and the server). So, the idea is when a user wants to switch to a different channel, I want to create another connection but keep the first connection (paused), then after a while if the user want to go back to the paused session, I'll kill the new connection and resume. So, on the client side I'll have always one connection, but the proxy will establish different connections and feed the client on the same connection. The problem I'm assuming is that I am worried how the rtcp handlers behave on both side (client and server). When a new session is established, the proxy will send a new set of rtcp parameters to the client b/c it gets new rtcp values (of course, SIP also has refer method and the client will expect a new set of reports). So there may not be any problem. The problem will be when I get back to the paused session. Because, the server may have some statistics accumulated before the session is paused and will continue to add to those figures. So, my question is is there anyway that I can reset the rtcp parameters for the paused session so that I can use my setting. Or any other better way of solving this problem? The reason why I wanted this setup is to avoid the connection overhead from the client side and i can add new logics always.
Thank you. - Zelalem S. Grahamstown, SA _______________________________________________ gstreamer-devel mailing list [hidden email] http://lists.freedesktop.org/mailman/listinfo/gstreamer-devel |
