Reinhard Nissl	6ac9696e77	Remove a NAL unit's trailing zero bytes even when dst_length is 1. Consider the following byte sequence 00 00 01 0a 00 00 00 01 09 ... ^ ^ A B decode_nal() determines dst_length to be 1 (i. e. the byte between label A and B above). However, this byte is a trailing zero byte as the spec says the the current NAL unit is terminated by a byte sequence 00 00 00. The current code used a loop to decrement dst_length accordingly. But the loop doesn't start as the loop condition checks for dst_length > 1, which should read dst_length > 0. patch by Reinhard Nissl, rnissl gmx de Originally committed as revision 8689 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
Reinhard Nissl	ff82e429cb	scenario: A properly coded frame is followed by an end of sequence NAL unit, i.e. the four bytes 00 00 01 0a. When decode_nal() decodes the end of sequence NAL unit, it returns with dst_length == 0. The original code leads to a return -1 which discards the current properly decoded frame. patch by Reinhard Nissl, rnissl gmx de Originally committed as revision 8688 to svn://svn.ffmpeg.org/ffmpeg/trunk	18 years ago
