Audio / Video Sync Issue with BBC iPlayer Downloads

Post by hans302 »

Hi - I am downloading content from BBC iPlayer using the PASTE AND ADD TO LIST function on the main screen and then selecting 50 FPS - Everything downloads fine, but the output file gradually looses Audio/Video synchronisation after around 1 minute (The Audio is ahead of the video by around half a second and gets gradually worse) - I have checked the output on my PC and on my APPLE TV and the same issue occurs on both devices.

When I download the same content using LINK FINDER and convert the FLV file to MP4 - Everything works OK - Could it have something to do with when the program stitches together all of the segments when it prepares the MP4 file?

Here is the BBC iPlayer LINK

Any ideas

Regards
Hans

There is no issue playing the 50 fps MP4 file on Win10 with Windows Media Player, VLC or BsPlayer.

Must be an IOS and Apple issue then - As when playing on my APPLE TV via iTunes (after downloading using your software) the AV sync is out by around 4 seconds at the end of the half hour programme.

I will continue to use LINK FINDER from now on for BBC iPlayer downloads.

It's a frame rate issue. I had the same problem. DL 25fps flash and convert with vlc to mp4 to solve the issue. For some reason the program is treating the 25 and 50 fps as slightly less than that fps (something like 24.9ish and 49.9ish) and so it slowly slips.

Please try version 10.02.15, the FPS issue should be fixed now for BBC videos.
