Frame sync notices lead to incomplete encoding

[kylegilman]

@chiggyman brought this up in #165

The frame sync error probably looks like this

[libfaac @ 0x959e080] 1 frames left in the queue on closing

Need to add check for that message which will allow for the several different aac encoding libraries.

[chiggyman]

This is the error I've been having, is replicatable.

[chiggyman]

Any movement on this? I have probably 4/5 video files at the minute which I can't get up due to these niggle even though the video files have encoded fine. Is there a specific method that checks for messages in the log file to check for completion? If so I will dig around see if I can alter it

[kylegilman]

Can you send me a link to one of those videos? I've never been able to reproduce the bug so I can't test to make sure it's fixed. kylegilman@gmail.com if you don't want to post it publicly.

[chiggyman]

Sorry for the delay Kyle, video can be found at http://iotimelapse.co.uk/wp-content/uploads/2014/06/QMCA52Bridge.mov it's a big file but we have decent bandwidth so shouldn't be too bad.

[kylegilman]

That is a monster file. I don't know what your workflow is like, but if I were you I would compress it using Handbrake before uploading to the server. Unfortunately I did not get a frame left in the queue when compressing that file so I still don't know if my solution works. If you want to try the development version and test it yourself, you can download it here.

[chiggyman]

Sorry about the file size! That's weird, just tried it again using the new dev version of the plugin and it still says failed due to frames left, and that was using the video that i've put in the link above. Error listed is [libvo_aacenc @ 000000000301c000] 1 frames left in the queue on closing It's a newish version of ffmpeg, that's the only difference I can think of? What version are you using?

[chiggyman]

Tried to edit the preg_match statements and can't quite follow the code, just for debugging the log file of a failed encode is below, i've removed some of the status encodes as they just repeat.

[kylegilman]

The problem is libvo_aacenc, which is the worst of the available AAC encoders. The plugin is set to use any other AAC encoders if they're installed. I just forced ffmpeg to use it on my development server and I was able to duplicate the message so I'll be able to fix it now.

[chiggyman]

After reading that it might make more sense for me to force my ffmpeg to use the better codec?

Edit; Tried this and changed the order so the experimental aac encoder is used before libvo_aacenc and it works fine, and sounds better.. Going to look at recompiling a version of ffmpeg with libfaac etc

Also working on moving off this IIS hunk of junk..

[kylegilman]

Sure, if you can I would recommend re-compiling FFMPEG and enabling libfdk_aac. I've fixed this frames left in queue error though.
