The output loop used sw_frame->width as the write size for all planes. This is only correct for NV12 where the interleaved UV plane happens to have the same byte width as the Y plane. For other pixel formats (e.g. YUV420P where U/V planes are half width, or P010 where samples are 2 bytes), the output would be corrupted. Use av_image_get_linesize() to compute the correct byte width for each plane based on the actual pixel format. Signed-off-by: Jun Zhao <barryjzhao@tencent.com> |

FFmpeg examples README ---------------------- Both following use cases rely on pkg-config and make, thus make sure that you have them installed and working on your system. Method 1: build the installed examples in a generic read/write user directory Copy to a read/write user directory and run: make -f Makefile.example It will link to the libraries on your system, assuming the PKG_CONFIG_PATH is correctly configured. Method 2: build the examples in-tree Assuming you are in the source FFmpeg checkout directory, you need to build FFmpeg (no need to make install in any prefix). Then just run "make examples". This will build the examples using the FFmpeg build system. You can clean those examples using "make examplesclean" If you want to try the dedicated Makefile examples (to emulate the first method), go into doc/examples and run a command such as PKG_CONFIG_PATH=pc-uninstalled make -f Makefile.example
