| Summary | 0007533: Simultaneous conversion of WMV to MP4 results in errors | ||||
| Description | As tested on auto-conversions during syncing and on ordinary conversions, converting of >1 file at once (in my case usually 4) results in random errors (MM crash, MM apparent freeze or reports that the file can't be decoded, even though it normally plays). | ||||
| Additional Information | Sample WMVs uploaded to FTP. | ||||
| Tags | No tags attached. | ||||
| Fixed in build | 1360 | ||||

We should find out: 1. Which DS filter isn't thread-safe. 2. Try to fix it (preferred). 3. In case 2. won't be possible, add a lock that would prevent multiple usage of such a filter. |

Few more details: a. AVI (xvid) -> MP4 works fine, but if many conversions (e.g. 8) are started simultaneously from a network drive (i.e. slightly slower one), at least one of them fails in ~5 seconds (as discussed with Michal, probably a timeout). b. many other conversions (WMV->MP4, AVI->WMV, ...) fail sometimes during the process, which seems to indicate something that isn't thread-safe. |
|
|
Fixed in build 1360. Video conversion was moved to separate process(es), so it should work ok already, please test it. |

Confirmed, there's currently no problem in converting any number of video simultaneously. |
