I am trying to use tinycompress for hwdecoder. everything works fine, but after compress_open (with profile = SND_AUDIOPROFILE_AAC level=0 ch_mode=0 rate_control=0), the playback of my aac-ltp-16bit-48KHz-Stereo file is faster than it should be. Am I wrong?
Vinod is probably the person for this one, as I am not so familiar with what you guys have done internally. However, my guess would be you are not setting the sample_rate correctly? It likely needs to be set to the appropriate SNDRV_PCM_RATE_XXXX define. The source for cplay included in the tinycompress repository is a good example of using the tinycompress library.

thanks, Charles. the print log showed me that I have set SNDRV_PCM_RATE_48000 which seems no problem. the cplay example code is only for mp3 file, and it also not set .level, .ch_mode and .rate_control. Vinod, what's your suggestion?
thanks, Keyon
