| Summary | 0000826: mpeg resolution extraction off by 1 bit... | ||||
| Description | The libextractor mpeg modules seems to extract resolution wrongly. It seems there is a binary shift of 1 bit... A video with a resolution of 720x480 is recognized as 721x224 A video with a resolution of 352x288 is recognized as 353x32 | ||||
| Additional Information | libextractor 0.4.0 | ||||

Hmm. It works for a couple of mpegs that I have. Could be related to the mpeg version -- some mpegs don't seem to parse at all. Would help to have some documentation about the various formats :-(. |
|
|
A good way of doing this would to look at mplayer's source. I found no mpeg file for which the resolution is badly calculated. (I have loads of them). |

Well, could you provide me with a sample (maybe just the first few frames) of an mpeg file where libextractor IS wrong? I mean, for testing, I don't just need code to show how to do it right, it would be nice to have a file showing that we are wrong now (and showing afterwards that the issue is resolved). |

Resolved by switching to libmpeg2 for parsing mpegs. |
