MP4ビデオファイルを再生するとき、私のAcer Iconia A500はフレームをドロップしてビデオアーティファクトを作成します。それはMP4をサポートしていないか、または私がダウンロードできるより良いMP4プレーヤーがありますか？
When playing back MP4 video files my Acer Iconia A500 will drop frames and produce video artifacts. Does it just not support MP4, or is there a better MP4 player I can download?
Update: Turns out it was just an issue with 1080p video. 720p video plays back great.
This has nothing to do with the file being of type mp4 and everything to do with the video codec being used. If you have video files that are not playing particularly well on the tablet, you should consider looking at Handbrake, a free piece of software that allows you to convert video formats. In-depth instructions are available at How to: Handbrake and A500 on xda-developers.
Basically, you want to use the following settings in the application:
There are some settings that can be tweaked in the Advance tab (see the forum post I linked). You can then save this profile in Handbrake and run this for any video files you encounter.
For playback on the Iconia, I use Mobo Player but there are others that work fine.
You could give a try to a pre-alpha version of VLC. Be warned this is not a finalized application and there might be errors, but it's still worth a try.
Have you tried MX Video Player with the MX Video Player CODEC (ARMv7)?
I can't answer the first part of your answer. For the question better MP4 player I'd suggest you Mobo Player and Rock Player.
