我能夠編碼YUV文件的MP4使用HEVC:如何使用ffmpeg生成編碼的HEVC比特流?
ffmpeg.exe -f rawvideo -s 1920x1080 -pix_fmt yuv420p -i input.yuv -c:v hevc -r 30 -x265-params crf=27 -vframes 300 -an -y test.mp4
這裏是mp4box -info test.mp4顯示:
* Movie Info *

但我怎麼能得到decodeble比特流?我試圖
mp4box -raw 1 test.mp4 -out out.bin
它提供:
Extracting MPEG-H HEVC stream to hevc
但out.bin無法通過HM或elecard進行解碼。
感謝
HM不是那麼多的問題嗎?你知道mp4box的輸出是NALU流還是字節流? – slhck 2014-10-30 20:58:26
哦,你應該可以使用'ffmpeg -i input.mp4 ... -c:v hevc -f hevc out.bin'來生成附件B字節流。 – slhck 2014-10-30 21:05:54
This Works!謝謝。 – jgmao 2014-10-30 21:48:47
