TS file generated contains invalid aac sample rate

[alexj212]

I am generating TS files, and the aac track sample rate is not stored correctly. The sample rate is set to 48000, 1 channel, AOT_AAC_LC.

	mPEG4AudioConfig := aacparser.MPEG4AudioConfig{
		SampleRate:      48000,
		SampleRateIndex: 0, // if 0 will be calculated
		ChannelConfig: 0,                  // if 0 it will be calculated
		ChannelLayout: av.CH_FRONT_CENTER,
		ObjectType: aacparser.AOT_AAC_LC,
	}
