  • How to increase performance of bitmap drawing on Android

    20 avril 2012, par vitakot

    I created a movie player based on FFmpeg. It works fine. The decoding is quite fast, on LG P970 (Cortex A8 with Neon) I have an average 70 fps with 640 x 424 resolution video stream including YUV2RGB conversion. However, there is one bottleneck. It is drawing on Canvas.

    I use jnigraphics native library to fill picture data into the bitmap in the native side and then I draw this bitmap on Canvas in SurfaceView. It is quite simple and common approach, but the drawing takes 44 ms for bitmap with 640 x 424 resolution which reduces fps to 23 and makes this technique unusable... It takes a lot more then the whole A/V frame decoding !

    Is there any method how to draw bitmaps significantly faster ? I would prefer to render completely in the native code using OpenGLES 2, but I have read it also could be slow. So what now ?...

    How can I render bitmaps as fast as possible ?

  • Stream H264 To Android Using FFMPEG

    26 février 2013, par GroovyDotCom

    I'm trying to stream a .ts file containing H.264 and AAC as an RTP stream to an Android device.

    I tried :

    .\ffmpeg -fflags +genpts -re -i 1.ts -vcodec copy -an -f rtp rtp ://127.0.0.1:10
    000 -vn -acodec copy -f rtp rtp ://127.0.0.1:20000 -newaudio

    FFMPEG displays what should be in your SDP file and I copied this into an SDP file and tried playing from VLC and FFPLAY. VLC plays audio but just gives errors re : bad NAL unit types for video. FFPLAY doesn't play anything.

    My best guess if that the FFMPEG H.264 RTP implementation is broken or at least it doesn't work in video passthru mode (i.e. using the -vcodec copy).

    I need a fix for FFMPEG or an alternate simple open-source solution. I don't want to install FFMPEG in my Android client.

    thanks.

  • Android FFmpeg video lag

    20 mars 2012, par user1281499

    I am working on to get a video player built for android using ffmpeg.
    I went through the following links to start building the player.I also went through the tutorial for building a player using ffmpeg and SDL by dranger on ffmpeg site. But I am facing problem of audio being not sync with the video for high resolution videos. For low resolution videos the audio and video both are in sync. I also saw a question addressing the problem with sws_scale() in ffmpeg (it may be slow), but as ffmpeg tutorial tells us that it is optimized, what can be the problem. I am using a surface and drawing the generated bitmap on the canvas. Is there any other method we should try.
