faq

Vitamio name of the origin of Vitamio's Chinese name is " Vichy ." Vitamio from the English word Vitamin(vitamin), I hope Vitamio for the importance of Android multimedia developers, like Vitmain to the human body as indispensable. What's the relationship between Vitamio and Vplayer? Vitamio based on Vplayer development, so vplayer can play the Vitamio can also. Vitamio which instruction set is supported by the CPU? support ARMV6 and ARMv7 two kinds of ARM CPUs, while the VFP, VFPv3, NEON and other instruction sets are optimized accordingly. the Android version supported by Vitamio supports Android 2.1+ system and supports more than 95% Android Market. The Android 2.1 system was also basically supported, but no detailed tests were done. E/vitamio (1557): Java.io.FileNotFoundException:No content provider This is not a mistake, it's a normal process. Now play the video is done: first the URL as a contentprovider to open, if not open, directly as a URL to open. video/Video streaming (RTP, RTSP, etc.) can't play the problem! There are several possible situations where the video itself is problematic and you can play it with another player. Local speed does not give force/device itself is too low configuration. Video source card, itself bandwidth is not enough, direct access is also very slow. Nested m3u8 address video is encrypted it is recommended to use Vplayer and other players to test the video to ensure that external factors are excluded. How do I call Vplayer to play a video?  private void Startplayer (string url, string title) {Intent i = new Intent ();    I.setcomponent (New ComponentName ("me.abitno.vplayer.t", "me.abitno.vplayer.VideoActivity"));    I.setaction ("Me.abitno.vplayer.action.VIEW");    I.setdata (uri.parse (URL));    I.putextra ("DisplayName", title);  StartActivity (i); }How to ignore the confusion of Vitamio related class libraries when confused? -keep class io.vov.utils.** {*;} -keep class io.vov.vitamio.** {*;} Drag the progress bar while playing, the drag progress is not accurate? This is normal, not the player's problem. By default seek to the nearest keyframe, there is no guarantee that keyframes will be on any timestamp unless you are intra-only encoded. How do I turn on hard decoding? Enables the second parameter when instantiating MediaPlayer. Public MediaPlayer (Android.content.Context ctx, boolean preferhwdecoder)Why does each software upgrade re-unpack the decoding package? To ensure consistency with the version Vitamio in the current upgrade software. Vitamio Java layer Code has been exposed, you can change your own logic. 

Development Recommendations

1, the use of the Android Library mode Vitamio easy to use, easy integration, not prone to error. Jar mode is also supported for use. 2, to the player's activity settings android:process such as android:process= ": Vitamio", close the activity to kill directly, to prevent the underlying library may exist a bug caused by the crash. Similarly, you can switch episodes by turning off activity and re-startactivity. 3, increase the buffer processing into the player activity when the default display "Loading ...", the first start after the hidden, other reference website buffer processing documents can be. Otherwise there will be a black screen in the first time. 4, Android TV box is recommended to use the default RGB565 box if there is a flower screen or blurred situation, the general use of RGB565 can be.  5, balance compatible with more devices and Vitamio package size compatible CPU architecture more (ARM, x86, MIPS) Vitamio the larger the package, if you only want to support armv6+ device, you can use Dist/online_ Arm under the so, generally applicable to online video playback , if it is too large, you can use 7z decompression libarm.so, you can see the following folder and correspondence: <=> armv661 <=> vfp70 <= > armv771 <=> neon can be self-cropping and re-packaged. For more information, see hereHttps://github.com/yixia/VitamioBundle/wiki/How-to-use-Vitamio-4.2.0-online-version%3F6, set the appropriate buffer size Vplayer default buffer size setting (setbuffersize): If it is local video, set to 0; Network video, set to 512 * 1024 (in bytes). After onprepared, you can also set the volume, screen quality, anti-interleaving parameters. 8, set the speed play (Fast forward fast Rewind) MediaPlayer Setplaybackspeed method, the value range [0.5-2.0], the default 1.0.  9, set the edge of the next function file download setdatasouce use form uri.parse ("Cache:/sdcard/download.mp4:" + Uri), note that the path of the cache to exist and can be accessed. 10, concern, use the latest version of the Vitamio version of the latest release package address: Https://github.com/yixia/VitamioBundle/releases11. Users who are unfamiliar with git can also use SVN to fetch code from github such as 4.2.2RELEASE:SVN checkout https://github.com/yixia/VitamioBundle/tags/v4.2.212.
