[AquilesCanta]

A fix for this will be pushed soon. You might already know this, but #1967 is also relevant here. You will need to pass FLAG_ALLOW_NON_IDR_KEYFRAMES to the TsExtractor for media to play correctly.

[needz]

@AquilesCanta, the problem is that this FLAG is already set manually in ExoPlayer code to true, but it doesn't help. This flag is definitively working for other streams that required it.

public H264Reader(SeiReader seiReader, boolean allowNonIdrKeyframes, boolean detectAccessUnits) {
    this.seiReader = seiReader;
    this.allowNonIdrKeyframes = true;
    this.detectAccessUnits = detectAccessUnits;
    prefixFlags = new boolean[3];
    sps = new NalUnitTargetBuffer(NAL_UNIT_TYPE_SPS, 128);
    pps = new NalUnitTargetBuffer(NAL_UNIT_TYPE_PPS, 128);
    sei = new NalUnitTargetBuffer(NAL_UNIT_TYPE_SEI, 128);
    seiWrapper = new ParsableByteArray();
  }
