在实现 Drm Dash 媒体源时，会发生以下异常。 MediaCodecRenderer$DecoderInitializationException:解码器初始化失败:OMX.Exynos.avc.dec.secure
下面列出了错误报告

最佳答案
我之前在尝试播放 hlsv6-widevine DRM 游戏时遇到过同样类型的错误。
com.google.android.exoplayer2.mediacodec.MediaCodecRenderer$DecoderInitializationException: Decoder init failed: OMX.Exynos.avc.dec.secure, Format(1, null, null, video/avc, avc1.640028, 1461621, null, [854, 480, -1.0], [-1, -1])
第一次玩DRM游戏时出现这种情况(可以正常播放)； 然后切换到非DRM标题但忘记释放之前的exoplayer实例； 当非 DRM 标题完成后切换回 DRM 标题时，发生错误。
当我在播放每个标题后及时释放 exoplayer 实例后，错误消失了。
从与MediaCodec错误相关的exoplayer问题来看，大多数错误是由于设备的媒体编解码器资源有限而没有及时释放exoplayer实例(资源)引起的。 或者玩家试图将解码的数据渲染到无效的表面( View )。 https://github.com/google/ExoPlayer/issues
希望回答可以帮助到您。
