Ac3 audio in MKV/AVI

[CrzyHorse]

Does it is supported? I have smartbook surfer with iMito 1.2 firmware and it cannot play ac3 audio. Is it a firmware problem?
Do you have any suggestions?

Encode the stream into something else...

Thank you for reply, but I don't think this is a solution. I find on smartbook site this pdf http://smartbookservice.de/SmartbookSurferCodecs.pdf
AC3 should be supported, so it may be a problem with iMito firmware I put on it...Do someone have similar device with working ac3?

Audio tracks in AC3 (identifyed by VLC as 'a52 Audio (aka AC3)'
play perfectly fine on my M701-HDMI 2GB @#181
the AC3 is embedded in a MKV.
The Video is encoded in 720p H264 MP4 AVC.
(no alternate audio streams or subtitles are embedded)

My m701 was not able to play Audio in a 1080p MKV with 'DTS' audio.

If you have a sample file, I can try it on my X5A

Thank you, this confirm that the tablet can read and that probably it is a firmware problem.

How do I pass the file? I founded a 10MB file on 4shared with ac3, rip of Clash.of.the.Titans. As I think it is copyrighted, I cannot post link. I can't find how to send private messages..any suggestions?

I've tested original smartbook surfer and dawa firmware. Both can read ac3 in mkv/avi.
I've tried to push all files in smartbook surfer system/lib dir on the tablet with imito firmware (that is the best, in my opinion) and it can read ac3.
As I don't want to replace all files, as tablet may be less stable, I'd like to replace only minimum set of files to enable ac3 decoding. I put these files there were not present on iMito but ac3 is still missing:
libdvbt.so
libdvbt_jni.so
libisdbt.so
libisdbt_jni.so
libOMX.TCC.ac3dec.so
libOMX.TCC.alsasink.so
libOMX.TCC.bsacdec.so
libOMX.TCC.clocksrc.so
libOMX.TCC.DVBDemux.so
libOMX.TCC.DVBTTunner.so
libOMX.TCC.DxB.audio.so
libOMX.TCC.DxB.AudioDec.so
libOMX.TCC.DxB.VideoDec.so
libOMX.TCC.DxB.VPUDec.so
libOMX.TCC.fbdevsink.so
libOMX.TCC.image_fbdevsink.so
libOMX.TCC.ISDBTDemux.so
libOMX.TCC.ISDBTTunner.so
libOMX.TCC.PADParser.so
libOMX.TCC.tdmbdemux.so
libOMX.TCC.tdmbrec.so
libOMX.TCC.tdmbtuner.so
libtdmb.so
libtdmb_jni.so
Any suggestion on which file I should put?

To make AC3 work in movies you need to push 2 files from DAWA or Smartbook surfer firmware to system/lib/ directory:
libOMX.TCC.ac3dec.so
libTCC_CDK_CONFIG.so
View attachment $AC3_IMITO.zip - script and 2 files (without adb)

View attachment $AC3_MALI_USB_FIX_IMITO.zip - automatic script including adb to patch iMito v1.2 - AC3 in video, fixed mali video driver, fixed build.prop, added libusb.so (if you whant to use it with different ROM - edit your build.prop)

This patch files are only for Telechips 8902 Android 2.1 system.
Don't forget to make backup!

AC3 sound in movies on Android 2.3.3 ROMS here.
