1. Install Yasm, x.264, Lame, and libvpx in sequence with reference to (1;

2. See (2) install ffmpeg, libavcodec-dev, libswscale-dev, libx264-dev;

3. Modify/usr/include/libavutil/common. h by referring to (2) and add the following content.

# Ifndef UINT64_C

# Define UINT64_C (value) _ CONCAT (value, ULL)

# Endif

4. Modify shower. cpp in the sunkwei source code file to block the original four lines of code, and then add a line of code as follows:

Int got; // modify it from here
// Block the AVPacket pkt of the Bank;
// Block the row pkt. data = buf;
// Block the row pkt. size = rc;
// Block the int ret = avcodec_decode_video2 (dec, frame, & got, & pkt );
Int ret = avcodec_decode_video (dec, frame, & got, buf, rc );
// Modify it to this row, and the code below does not move
If (ret> 0 & got ){

The reason for the modification is that the ffmpeg version is different. The Library version I installed with apt-get install libavcodec-dev is lower than that used by the source code author. In my library, avccodec_decode_video2 is not used, and only avccodec_decode_video.

After the modification is complete, go to the source code directory and make it. The compilation result is displayed successfully. Run the command to check the effect.
