This is somewhat a follow-up to question:
m3u8 file not playing in Android Emulator
I have a very similar issue to the one asked over there, but with a real device where JB has been ported to (project details at: http://groups.google.com/group/renesas-emev-osp/topics):

...
As for the emulator case above, the OMX_GetExtensionIndex call fails, as the vendor OMX implementation doesn't include the NativeBuffer-related functions:
https://github.com/Renesas-EMEV2/Renesas-device_emev/blob/emev-4.1/omf/OMF_Extension.h
In the OMXCodec (used by the AwesomePlayer to succesfully play mp4 files) initNativeWindow() isn't invoked at all (as per debug logs I've captured).
Also, our JB porting included this additional check for componentName, in the OMXCodec creation:
OMXCodec::OMXCodec(
const sp<IOMX> &omx, IOMX::node_id node,
uint32_t quirks, uint32_t flags,
bool isEncoder,
const char *mime,
const char *componentName,
const sp<MediaSource> &source,
const sp<ANativeWindow> &nativeWindow)
: mOMX(omx),
...
mNativeWindow(
(!strncmp(componentName, "OMX.google.", 11)
|| !strncmp(componentName, "OMX.RENESAS.", 12)
|| !strcmp(componentName, "OMX.Nvidia.mpeg2v.decode"))
? NULL : nativeWindow) {
...
So, looks like mNativeWindow is nullified in our case (OMX.RENESAS.) and that makes a bunch of logic being skipped, including initNativeWindow of course.
Adding this same check, not to call the InitNativeWindow logic, in ACodec::onConfgureComponent:
if (msg->findObject("native-window", &obj)
&& strncmp("OMX.google.", mCodec->mComponentName.c_str(), 11)
&& strncmp("OMX.RENESAS.", mCodec->mComponentName.c_str(), 12)) {
...
CHECK_EQ((status_t)OK, mCodec->initNativeWindow());
}
NuPlayer isn't crashing anymore on the m3u8 playback, but screen remains black on m3u8 playback, while audio goes on!
Comparing logs from the OMXCodec (mp4 - OK) vs ACodec (m3u8 - black outout) I can see similar calls repeating:

...
but looks like something else is still missing...
Any suggestion?
