Hi,
My current system:
***
OS: Ubuntu Linux 14.04 with 3.14.5-MSSr6 #1 SMP.
Hardware: Intel(R) Core(TM) i7-5557U CPU @ 3.10GHz
***
1) I managed to complete the detailed instruction for installing intel
media sdk on generic Linux OS.
I followed the instruction given in
- https://ffmpeg.org/pipermail/ffmpeg-user/2015-October/028761.html
-
https://software.intel.com/en-us/articles/how-to-setup-media-server-studio-on-secondary-os-of-linux
2) I also compiled the latest ffmpeg from github following the procedure
presented in
https://ffmpeg.org/pipermail/ffmpeg-user/2015-October/028761.html
3) I was testing compression of video camera feed using the command
>> /opt/ffmpeg_qsv/bin/ffmpeg -f v4l2 -framerate 30 -video_size 640x480 -i
/dev/video0 -c:v h264_qsv out.mp4 -loglevel 1000000
*I got the following error:*
[h264_qsv @ 0x2e327e0] Error initializing an internal MFX session
Error while opening encoder for output stream #0:0 - maybe incorrect
parameters such as bit_rate, rate, width or height
*Things that I tried:*
1) ensure user is part of video group
2) Run the command with sudo and su
3) export LD_LIBRARY_PATH (export
LD_LIBRARY_PATH=$LD_LIBRARY_PATH:/opt/intel/mediasdk/lib64)
4) add ld.so.conf
/etc/ld.so.conf.d/intel-mediasdk.conf -> /opt/intel/mediasdk/lib64
5) ldconfig -p -N | grep intel.mediasdk
libmfxsw64.so (libc6,x86-64) => /opt/intel/mediasdk/lib64/libmfxsw64.so
libmfxhw64.so (libc6,x86-64) => /opt/intel/mediasdk/lib64/libmfxhw64.so
6) Testing with a sample yuv file instead of camera feed got the same error
Please see the detailed log attached.
Any help to proceed next would be appreciated.
Regards,
Jay
