* 4xm: replace forcing EMU_EDGE by a copyAnton Khirnov2014-01-06
| | | | | | | | | | | The decoder currently sets CODEC_FLAG_EMU_EDGE and relies on get_buffer2() to always provide buffers with linesize == 2 * width. This is wrong, since we place no such restriction on get_buffer2() implementations. Fix this by decoding into internal buffers and copying them to output frames. Since this is a very obscure decoder, the performance hit should not be an issue.

| | | | | | Directly return from code 1, 2 and 6 codepaths and simplify the remaining one to have a single overflow check and a single call to mcdc.

* Revert "4xm: Prevent buffer overreads."Ronald S. Bultje2012-01-04
| | | | | This reverts commit 295a7c0238e84b0ffa8f21ed938d45f51f54a4cd. The patch breaks decoding of regular files (e.g. fate-4xm-2).

* 4xm: pass the correct remaining buffer size to decode_i2_frame().Aneesh Dogra2012-01-04
| | | | | | | frame_size is the number of bytes left in the packet, so if we are passing buf-4 we can safely read frame_size+4 bytes. Signed-off-by: Ronald S. Bultje <rsbultje@gmail.com>
