Audio/Video Sync Problems With Auto-Transcoding
|Reported by:||anna||Owned by:||anna|
|Who will test this:|
Some file formats (particularly wmv and avi) are not being handled well by Indytube/mencoder. The audio is out of sync and the video often appears in fast motion resulting in a 5 minute video lasting only 10 seconds. The audio will continue playing after this. The duration is often reported incorrectly.
Other videos will play more or less normally but the audio will be significantly out of sync.
Here is a version on plumi demo - http://demo.plumi.org/Members/qwerty/videos/cliplarage-medium.wmv/view
And on EM stable http://www.engagemedia.org/Members/AnarchiaFilms/videos/shv-train-track-court-1.mp4/view http://www.engagemedia.org/Members/jonair/videos/nonregularworkersstruggleinnewcoreeland.wmv/view
It seems mencoder has difficulty transcoding files with a variable frame rate. WMV files frequently have a variable frame rate. This may not be the only explanation, but it appears to be the major one.
