I use this to loop video in the Grafika video player (see MoviePlayer#doExtract()).
Helping for solve this issue is kindly appreciated. It is time consuming process for large file size of. But the user set the SeekBar to previous position, the SimpleExoPlayer re-buffering to displaying the video. You can flush() the decoder when you hit end-of-stream and just start feeding in the next file. After running the app SimpleExoPlayer buffering the content of the video and playing smoothly.
#SMOOTHEST PLAYER FOR MP4 VIDEO MOVIE#
Update: If you can guarantee that your movie clips have the same characteristics (size, encoding type - essentially everything in MediaFormat), there's an easier way. If the recordings were taken at fixed frame rates it's easy enough, but some sources (e.g. Incidentally, you'll need to figure out how much of a delay to put between the last frame of movie N and the first frame of movie N+1. There's some additional examples in Grafika, though the video player there is closer to what you already have (decoder outputs to TextureView). From there you just need to render the texture to your surface ( SurfaceView? TextureView?), using something like the STextureRender class in CameraToMpegTest. You can see an example of rendering MP4 files to a SurfaceTexture in the ExtractMpegFramesTest example. What you can do instead is decode to a SurfaceTexture, and then draw that on the SurfaceView (using, as you thought, OpenGL). You'd need to tear down the first before you can proceed with the second, and I'm not sure how close you can get the timing. What you describe with using multiple instances of MediaCodec will work, but you can only have one "producer" connected to a Surface at a time. So, is there any other possibility for doing that? Maybe using OpenGL? It seems to me that one surface can only be used by one decoder simultaneously. Furthermore the first frame is also queued via decoder.queueInputBuffer.īut doing so results to the following error: 01-13 16:20:37.182: E/BufferQueue(183): connect: already connected (cur=3, req=3)Ġ1-13 16:20:37.182: E/MediaCodec(9148): native_window_api_connect returned an error: Invalid argument (-22)Ġ1-13 16:20:37.182: E/Decoder Init(9148): Exception nfigure: For a smooth fade between two different video sequences I was thinking about having an init functionality where the second video is already initialized via nfigure(format, surface, null, 0) during the playback of the first one. By only creating (and configure) the second decoder after the first sequence has finished ( decoder.stop and decoder.release of the first one was called), one can see the blending.
In a first step it would be sufficient to achieve this only for my Nexus 7 tablet.įor displaying only one video I have been using the MediaCodec API in a similar way to and it works fine.
So, the viewer might get the impression of watching only one continuous video.
#SMOOTHEST PLAYER FOR MP4 VIDEO ANDROID#
I want to play (render to surface) two or more consecutive mp4 video sequences (each stored in a separate file on my device and maybe not present at startup) on my Android device in a smooth (no stalls, flicker, etc.) manner.
