Did you check the file media_codecs.xml to see if the content is changed correctly after flashing the new file?
I don't understand why the avc video encoder [OMX.qcom.video.encoder.avc] is not used first.
I will develop a lib for displaying the full debug info when I have time.

Yeah I checked the media_codes.xml file and the line was removed. Thanks for the effort you put into this, it's greatly appreciated.

I have enable the debug info for libstagefright.so
Please flash NexusOne-Desire_HW_video_decoding_and_encoding-h264_for_CM-10.2_debug_update.zip and post the logcat.

If h264 is still not working, please try m4v config and the debug-enabled libstagefright.so.

Here's the log, I only copied part of it because the rest of it is just a repetition

For the 2nd zip you provided, gallery froze after I stopped recording

I cannot access h264's logcat (the first link you provided). Your link doesn't work.

Regarding the m4v's logcat (the second link you provided), the qcom's hardware mpeg4 encoder is used.

But you need to patch the N1 kernel to fix the below error to make video recording working.
venc_drv_open::224 VENC_DRV_OPEN: FAILURE:venc_ioctl_initialize_done_recved FALSE
The solution was already posted in the second post of this topic.

Here's the link to the first logcat http://pastebin.com/T63jKWv4. I've been busy so sorry about the late reply. Also what commits do I need to make to the kernel? I'm having trouble figuring out how to apply the patch

Your logcat is not completed.
It seems that the software video encoder [OMX.google.h264.encoder] was used.
Could you provide a logcat when you start recording a video?
Note: You don't need to reply to me immediately. Just do it when you have free time.

According to kali7's research, you need intersectRaven's kernel commit, where he solved the h/w video encoding issues long time ago:
https://github.com/intersectRaven/ir-ke ... 5571bad194

You might also need to compare the whole source code among the following three git repositories.

• HD2's qdsp6_1550 (working hardware encoder)
• IntersectRaven's qdsp6 (working hardware encoder)
• Evervolv's qdsp6 (non-working hardware encoder)

Then "manually" modify the source code of your used Evervolv's android_kernel_htc_qsd8k.

Hey Tytung, I'm back.

Now that we have kitkat roms, has anything changed pertaining to video recording?

No, I used the same patch for both JB and KK.

I guess we didn't make it work because Evervolv integrated ion in 4.x kernel. As mentioned by tytung, we need to revert back the changes to make it work.

Hi there, first post here as I am an HTC Desire user. Please could you help up have at least 720p HW video decoding as you have provided for us in CM10.1 thread? I have found a patch you posted earlier but unfortunately is not working in our KK builds (neither evervolv nor CM/beanstalk/carbon/etc...). Maybe if you have time, could you take a look? Thanks in advance.
