A streaming media stream side, in order to realize the RTP audio video data, after the transcoding pushed to RTMP server (SRS)
Video h. 264 can be up to now, the RTMP player can also be played normally,
But the audio frame, because video equipment manufacturer is different, use different coding, now see the g. 711 a, g. 726, aac, mp3, PCM, adpcm,
RTMP media server only supports the PCM, ADPCM, G., 711 a, AAC, MP3, part of this is not supported, such as g. 726 coding,
You have any plan to make real-time streaming audio transcoding, arbitrary to aac audio coding?
The table below for the device may upload audio coding:

Using ffmpeg compiled for PCM decoding, and then into your aac, can also go directly code: in the example file transcode_acc. C under this file, but I've been slow on a mobile phone code, have yet to find out why
