ExoPlayer 2.18.6

More version details

rtmp播放中翻转90°后，exoplayer花屏。当rtmp视频翻转90后，视频的宽和高变化，比如之前是640480变成480640，rtmp服务器会再次发送VideoTagHeader信息，在VideoTagPayloadReader.java的parsePayload()方法中hasOutputFormat=true,不会进入if语句中，不会重新创建Format ，导致花屏。目前的处理是把 !hasOutputFormat判断条件去掉就OK了。
代码片段如下：
if (packetType == AVC_PACKET_TYPE_SEQUENCE_HEADER && !hasOutputFormat) {
ParsableByteArray videoSequence = new ParsableByteArray(new byte[data.bytesLeft()]);
data.readBytes(videoSequence.getData(), 0, data.bytesLeft());
AvcConfig avcConfig = AvcConfig.parse(videoSequence);
nalUnitLengthFieldLength = avcConfig.nalUnitLengthFieldLength;
// Construct and output the format.
Format format =
new Format.Builder()
.setSampleMimeType(MimeTypes.VIDEO_H264)
.setCodecs(avcConfig.codecs)
.setWidth(avcConfig.width)
.setHeight(avcConfig.height)
.setPixelWidthHeightRatio(avcConfig.pixelWidthHeightRatio)
.setInitializationData(avcConfig.initializationData)
.build();
output.format(format);
hasOutputFormat = true;
return false;
}
