我试图压缩视频。它在所有设备上都能正常工作，但在三星S5 中，它会出现以下错误。
错误日志：android.media.MediaCodec$CodecException: Error 0xffffec77

我已经预先指定了Height＆amp;视频压缩的宽度。上面的代码在另一个设备上运行良好。
答案 0 :(得分：1)
我在Samsung Note 4设备和 UHD视频选项（3840x 2160）上遇到了此问题。经过长时间尝试，它不会仅使用以下宽度和高度值引发异常：
resultWidth = 800;
resultHeight = 600;
或
resultWidth = 640;
resultHeight = 480;
您可以将以下值设置为此代码行：
MediaFormat outputFormat = MediaFormat.createVideoFormat(MIME_TYPE, resultWidth, resultHeight);
