由 风流意气都作罢 提交于 2019-12-12 12:42:15
问题 I'm having compatibility problems using videoview (or MediaPlayer) for play rtsp streams in multiple videoviews in the same activity. I have opened another question on this problem here but now I know that isn't my code the responsible, because I test same software on different phones and it work. Viewing logcat Info messages for RTSP setup I see that each phone has different implementation of stagefright (android multimedia framework): (A) I/RTSPEngine(147): User-Agent: Player/LG Player 1.0

Android browser media player (stagefright?) displayed media name

由 与世无争的帅哥 提交于 2019-12-12 09:49:16
问题 When the Android browser opens a media file it can play, the built-in (stagefright?) media player opens up to stream it. A title for this media is displayed on the player dialog, based on the URL. The URL in this case was http://10.0.37.195/waug_mp3_128k . The media player simply uses the last part of the path as its title. Is it possible to change the displayed title? I have tried a Content-Disposition header, but it had no effect: Content-Disposition: inline; filename=Some Better Title 回答1:

Android: MPEG4Writer fails to start when using OMXCodec as MediaSource

由 筅森魡賤 提交于 2019-12-09 18:44:26
问题 I'm trying to encode a video from a byte array buffer and to do so I'm using MPEG4Writer API from native code. I have created my custom MediaSource class to provide the data and I'm wrapping it with OMXCodec to give it to MPEG4Writer : sp<MediaSource> mVideoEncoder = OMXCodec::Create(client.interface(), omxEncMeta, true, mVideoOutSource); mVideoEncoder->start(); mVideoOutSource is my custom MediaSource class, omxEncMeta is the following: int32_t colorFormat = OMX_COLOR_FormatYUV420SemiPlanar;

问题 I have got FFmpeg compiled (libffmpeg.so) on Android. Now I have to build either an application like RockPlayer or use existing Android multimedia framework to invoke FFmpeg. Do you have steps / procedures / code / example on integrating FFmpeg on Android / StageFright? Can you please guide me on how can I use this library for multimedia playback? I have a requirement where I have already audio and video transport streams, which I need to feed to FFmpeg and get it decoded / rendered. How can

Android: NativeWndowBuffer ownership issue in omxcodec for hardware h.264 decoding in android 4.0.4

问题 I am working on stagefright to decode and display mp4 file in android 4.0.4 with hardware codec. Currently I am testing in Motorola Xoom device with android 4.0.4.

H264 HW Decoding on Android Using FFmpeg-10

由 穿精又带淫゛_ 提交于 2019-12-07 09:59:18
问题 I've noticed that ffmpeg has already included (libavcodec/libstagefright.cpp) and claimed to support H264's hardware decoding through StageFright framework. I've build the shared library according to (tools/build_libstagefright). But when doing real H264 frame decoding, it seems to be failed at Stagefright_init(). Does anybody succeed to use this new feature? Thank you in advance. 来源： https://stackoverflow.com/questions/9702503/h264-hw-decoding-on-android-using-ffmpeg-10
