ffplay: Broken sound in rtmp / rtsp streams

[alexandru]

Command:

ffplay rtsp://media2.lsops.net/live/aljazeer_en_high.sdp

This BUG is present both in 0.7rc1, as in 0.6x too.

[Carl Eugen Hoyos]

The stream decodes fine for me, what is the problem for you?
Please provide complete, uncut output of ffmpeg for all issues!

Please help me also with the commande line parameters too (for ffplay (I tested with it) and for ffmpeg if you need it too) to can provide you complete, uncut output of ffmpeg for all issues!

TO BUG IS VERY SIMILAR IN BEHAVIOR (BAD SOUND) WITH THE SOLVED .wma one, but of course we have here an rtsp/rtmp stream: please also run also run:

ffplay rtsp://media2.lsops.net/live/aljazeer_en_high.sdp

to here the bad sound.

Thanks.

Replying to cehoyos:

Please provide complete, uncut output!

The bug is simple the sound is not intelligible: please run it too with ffplay
Please indicate me the command line parameters that I need to run, to can generate the uncut output...I'm new here, and is not very clear for me what I need to generate in addition
that the command "ffplay rtsp://media2.lsops.net/live/aljazeer_en_high.sdp"

once the stream sound is altered.

But I will do it if you tell me what I need to run, to supply you the needed feedback

Thanks for your help

I can reproduce this issue with the latest source snapshot.

FFplay plays the audio track in slowdown.

Works fine with ffmpeg.

I experience the same results with the mms version of that stream, so it's likely not rtmp/rtsp specific. (They use the same encoder for the mms stream but send it over a windows media server)

Could you tell me the git version and eventually the file where this fix was done?

Thanks?

[alexandru]

Sorry...Thanks!
