java - Video Compression using Telegram's Code Android - Output surface wait timed out | MediaCodec -
the code i'm using repo : https://github.com/drklo/telegram/
in ~/src/main/java/org/telegram/android/video/mediacontroller class encoder , decoder instantiated, i'm getting "sufrace wait timed out exception" in outputsurface class no matter video i'm choosing.
tried on devices : nexus 4 (lollipop), asus zenfone 5 (kitkat), moto g (kitkat).
is there i'm missing? have not changed code @ all.
-- code snippet mediacontroller.java --

public void awaitnewimage() { final int timeout_ms = 2500; synchronized (mframesyncobject) { while (!mframeavailable) { try { mframesyncobject.wait(timeout_ms); if (!mframeavailable) { throw new runtimeexception("surface frame wait timed out"); } } catch (interruptedexception ie) { throw new runtimeexception(ie); } } mframeavailable = false; } mtexturerender.checkglerror("before updateteximage"); msurfacetexture.updateteximage(); } public void drawimage(boolean invert) { mtexturerender.drawframe(msurfacetexture, invert); } @override public void onframeavailable(surfacetexture st) { log.d("frame ","new frame"); synchronized (mframesyncobject) { if (mframeavailable) { throw new runtimeexception("mframeavailable set, frame dropped"); } mframeavailable = true; mframesyncobject.notifyall(); } } these code snippets might not make lot of sense , can't post complete code here because huge. can find complete code here : https://github.com/316karan/mediacodec-tele
the problem never receive frame on outputsurface , goes in infinite loop timeouts.
