Currently am playing with a 486 machine and encoding videos to play back on it. the machine plays videos just fine and plays them as expected without issue , however , the audio card seems to be the biggest bottleneck.
The videos being encoded are cinepak and the only audio codec option to go along with the video that is compatible with such an old machine is IMA 4:1. The machine will not play back the video smoothly unless the Sample rate is set as low as possible , 8000hz. Now 8000hz is somewhat listenable but it sounds god awful. The machine uses a soundblaster 16 and I'm thinking this may be the culprit.
I'm not 100% sure as far as sound card knowledge goes , but I'm guessing even though the soundblaster is capable of running higher sample rate audio it just becomes a bottleneck for the rest of the machine and the video jumps around and skips trying to keep them both in sync.
The VIDEO aspect of the machine is totally fine , I've pretty much perfected it's playback capabilities , it's just the audio that needs to be a bit better.
