The decoded audio data format can be checked in AVFrame.format, and also AVCodecContext.sample_fmt. For audio, check it with enum AVSampleFormat. Sample rate is in AVCodecContext.sample_rate. > Is it in LPCM > format or something else format? The most widely used is AV_SAMPLE_FMT_S16, which stands for signed 16bit samples. So the answer is practically yes. -- Andrey Utkin _______________________________________________ Libav-user mailing list [email protected] http://ffmpeg.org/mailman/listinfo/libav-user
