lib vlc android無法播放原始h264嗎？
[英]lib vlc android won't play raw h264?
問題描述
我需要開發一個使用vlc媒體播放器選擇rtsp流並播放原始h264的android應用。 我使用Mac OSx OSx按照AndroidCompile中的說明編譯了lib vlc android。 該項目編譯時帶有一些警告（如下所示），我能夠在Android平板電腦上運行vlc應用。 vlc應用程序可以很好地播放h264容器的rtsp流，但不能播放實時cam的原始h264。 下面的logcat顯示了一些unable to decode stream: java.lang.NullPointerException但是我在播放任何流的開始就已經看到了這些，我想是vlc試圖找出要使用的解碼器。 如日志貓所示，它確定h264。 播放服務宣布開始播放后不久，它宣布播放服務結束。
在Google Play商店中找到的vlc android應用能夠正常播放同一提要，因此提要沒有任何問題，並且發行版具有編解碼器和功能，可播放原始h264。 C/C++庫的編譯方式可能有問題嗎？ 還是libvlc（已編譯）默認情況下不播放原始h264？ 我尚未修改AndroidCompile項目中的任何源代碼。 是否有人編譯過libvlc並能夠播放原始h264的rtsp流？ 或者我應該考慮將流傳送到容器中並從容器中播放，我該怎么做？
我的機器上運行的Mac OS X，運行compile.sh腳本我安裝了構建工具建議之前，該項目從運行Android Studio 。 在logcat下方，以及項目編譯時的警告摘要。
