Unable to stream data with multichannel (L16) codec #93

Closed jaredhagel closed 4 years ago

jaredhagel commented 4 years ago

Recently I’ve tried using the ‘LPCM 44 kHz Stereo' codec to stream a wav file in stereo format to a device. To do so I used the following arguments to streamutil.c:

--remote=172.23.44.1:4000 --play-file C:\pjproject-2.10\pjsip-apps\bin\samples\i386-win32-vc14-debug\file_example_Test_44_1.wav --codec L16/44100/2

The file_example_Test_44_1.wav has a sample rate of 44.1kHz and has stereo channels (ie. left and right). When running this program I repeatedly get the error “Codec encode() error: Codec frame is too short (PJMEDIA_CODEC_EFRMTOOSHORT)”. Program output below:

You should report any errors related to pjsip to the official pjsip repository which can be found here: https://github.com/pjsip/pjproject

This repo aims to make pjsip available for Apple platforms (we just provide the build process)

Oh I see. Will do. Sorry about that.
