qsv和ffmpeg出现段错误....

[酷咪哥]

我已經成功的将Intel Quick Sync Video编译到ffmpeg，并且已在硬件加速，编码解码中查到对应的编解码器。

使用以下命令，执行成功：
root@mos:~/mscore_src/extern/src/ffmpeg# /usr/local/bin/ffmpeg -i udp://224.2.2.2:9000 -look_ahead 0 -pix_fmt nv12 -c:v h264_qsv -c:a copy -b:v 2M -preset veryfast -f mpegts udp://127.0.0.1:10000

但使用UBUNTU16.04和14.04进行以下验证操作时出现了错误，烦请帮忙指导一下:

问题已经解决，揭帖

楼主，问题解决后，执行hwaccel 的命令是可以正常执行的吗？

[sand_wiliam]

/bin/ffmpeg -hwaccel qsv -c:v h264_qsv -vsync 0 -i udp://224.2.2.2:9000 -look_ahead 0 -pix_fmt nv12 -c:v h264_qsv -c:a copy -b:v 2M -preset veryfast -f mpegts udp://127.0.0.1:10000 这串命令可以正常执行吗？有没有这样的错误：Error retrieving encoding parameters

[qq445712014]

博主，请问你是如何编译通过的啊，可以告知一下吗？
