| Subject: [PATCH] Use AV_INPUT_BUFFER_PADDING_SIZE to determine padding |
| size |
| |
| Hardcoding the value for FF_INPUT_BUFFER_PADDING_SIZE is not safe |
| because upstream FFmpeg might change it (as they did in FFmpeg 4.0). |
| |
| Instead, use FFmpeg's AV_INPUT_BUFFER_PADDING_SIZE if available and |
| only hardcode a value if FFmpeg is disabled (in which case the value |
| doesn't particularly matter anyway). For compatibility with older |
| FFmpeg versions, define AV_INPUT_BUFFER_PADDING_SIZE if hasn't been |
| defined yet. |
