Poor Playback with MPEG4 AVI

Hi guys,

 

I've been enjoying Rasplex for the past few days with no problems at all, until today. I have some AVI files wrapping mpeg4 and mp3 audio. They're 480p video and the bitrates for video and audio: 900 kbps and 192 kbps repectively. I don't believe any transcoding is going on, and I don't think that there's any problem with my WIFI connection because I can stream 1080p and 5.1 audio easily with no buffering. Unfortunately these files play in very short (~10 sec) spurts and verbose logs show lots of buffering going on. Any ideas on what could be the problem?

 

Thanks

It might not be the same issue, but in the past I have had odd issues with some AVI’s that simply would not stream properly. This could be fixed by dropping these AVI’s into VirtualDub and restream them, with VDub set to use ‘Direct Stream Copy’ for both Video and Audio (it is default for audio already). When doing this with some of the videos VDub itself gave a warning that the videos were badly optimized for streaming, and suggested restreaming as a cure.

Like I said, yours may be a different issue, but this cure is something simple to try, and it shouldn’t cause any harm even if it fails to fix the problem. The ‘Direct Stream Copy’ mode of VDub doesn’t alter the video or audio encoding in any way, but only modifies how the track data is stored for streaming.

Dlanor,

That's a really great point. I've delt with these codecs a lot and I was about to resort to manual transcoding. I hadn't even thought of streaming optimization. It worked perfectly btw! Thanks so much for the advice
