MPEG-TS stream freezes every several seconds #678

ddv2005 · 2015-07-31T16:33:05Z

I have MXIII box that works fine in MediaPlayer on MPEG-TS H264/AAC stream. But exoPlayer freezes every several seconds. You can see it in my log at 00:21:23.188 ..Out PTS: 191000... Next PTS: 191040 should be played at 00:21:23.228 but it freezes before 00:21:23.908 (about 700 ms delay). Why it happen?

Some relation with that: #488

ddv2005 · 2015-07-31T18:04:28Z

Thanks a lot. I have disabled OMX.amlogic.avc.decoder.awesome in MediaCodecUtil.isCodecUsableDecoder and now it works fine.

bsysop · 2015-07-31T18:13:41Z

Can you show how you do it?

When I try use exoplayer, video still black, but I using HLS and DASH!

ddv2005 · 2015-07-31T18:16:52Z

private static boolean isCodecUsableDecoder(MediaCodecInfo info, String name,
boolean secureDecodersExplicit) {
if (info.isEncoder() || !name.startsWith("OMX.")
|| (!secureDecodersExplicit && name.endsWith(".secure")) || name.startsWith("OMX.amlogic.avc.decoder.awesome")) {
return false;
}

bsysop · 2015-07-31T18:19:43Z

That awesome, let me try 👆

bsysop · 2015-07-31T21:14:50Z

Before screen are black, now have video, but still freezing, video are not 100% smooth!

Do you know your Android Version And or Amlogic Build version?

Thanks.

bsysop · 2015-08-25T16:10:33Z

@ddv2005 Finally can i say software decoder have no quality for this Hardware, please see more in #488

ojw28 · 2015-08-25T16:44:20Z

Does it work if you make it so that codecNeedsEndOfStreamWorkaround in MediaCodecTrackRenderer returns true for the video decoder? If so then we should just add the device/decoder combination to that method.

bsysop · 2015-08-25T17:45:00Z

Hi @ojw28, please check #488 just check last message, explain all about OMX.amlogic

ojw28 · 2015-08-25T17:46:02Z

That doesn't answer the question, because video shouldn't freeze even if the decoder isn't adaptive. Please give the suggestion above a try.

bsysop · 2015-08-25T17:52:24Z

I see! Then @ddv2005 should reply that, I using same decoder with MPEG-TS and no Freezing =/

@ddv2005 Maybe if you can publish some link/file i can try in my Amlogic (Old one) and check if same problem.

Just disable Omx.Amlogic, i think this not useful in all devices, like mine device, just have Omx.Amlogic and software Omx.Google (Then will be worst with this solution).

My issue was just with MPEG-Dash adaptive (Then in this case video show black screen), but now AmLogic staff solved that for me and they will publish the new firmware for public very soon.

Avetri · 2015-11-05T09:12:17Z

Hi @bsysop !
Have the adaptive video issues already been resolved by Amlogic? Do You have any information?

goffioul · 2015-11-05T15:56:40Z

[coming from #926]

@ojw28 I've tried to make codecNeedsEosPropagationWorkaround return true, but that didn't help. The video is still frozen, giving me 1 frame every 5 to 10 seconds.

I've also tried to other suggestion of making isCodecUsableDecoder to return false for OMX.amlogic.avc.decoder.awesome. The video is then not frozen anymore, but the performances are very poor, because of software decoding. This is not an acceptable solution for us.

Any other suggestion or things I can try?

ojw28 · 2015-11-05T15:59:36Z

Report the issue to the device manufacturer. There's only so much we can do to make sure we run properly on devices that don't behave correctly.

bsysop · 2015-11-06T03:00:47Z

@Avetri yes, they solved that, in some cases need to upgrade all the last media decoders, but normally just changing /system/etc/media_codecs.xml this works.

I change the avc and hevc for:

<MediaCodec name="OMX.amlogic.avc.decoder.awesome" type="video/avc" >
            <Limit name="size" min="64x64" max="1920x1088" />
            <Limit name="alignment" value="2x2" />
            <Limit name="block-size" value="16x16" />
            <Limit name="blocks-per-second" min="1" max="972000" />
            <Limit name="bitrate" range="1-300000000" />
            <Feature name="adaptive-playback" />
        </MediaCodec>
        <MediaCodec name="OMX.amlogic.hevc.decoder.awesome" type="video/hevc" >
            <Limit name="size" min="64x64" max="1920x1088" />
            <Limit name="alignment" value="2x2" />
            <Limit name="block-size" value="16x16" />
            <Limit name="blocks-per-second" min="1" max="972000" />
            <Limit name="bitrate" range="1-300000000" />
            <Feature name="adaptive-playback" />
        </MediaCodec>

goffioul · 2015-11-11T15:47:51Z

@ojw28 It appears my video problem only occurs with HLS. The test DASH streams from the demo app plays fine. Does that make sense, if the problem is the AMLogic decoder?

Avetri · 2015-11-13T12:44:03Z

@bsysop Thanks.

Could You look at #953 ?

ojw28 · 2016-06-09T23:23:56Z

It's somewhat unclear whether this is/was a device specific issue, or whether it still reproduces on recent versions of ExoPlayer. Closing for now. If this still reproduces on the latest ExoPlayer release, and if you believe it's not a device specific issue, then please file a new issue.
