I follow the demo and play a mov format video, there is only sound but no video... But if I use the base MediaCodec api with compile version 23 to play this video, it will be OK and everything is great.
here is the file link for this sample mov:

https://pan.baidu.com/s/1slnKXrv

based on exoplayer r2.0.4
a device with android 6.0
below is the adb log:

The issue here is most likely that the underlying platform is under-reporting the capabilities of the device to play video of type video/mp4v-es. On Pixel the decoder for this type is OMX.qcom.video.decoder.mpeg4, which claims to support a maximum decode width of 896px. Since the video provided is 1280px wide, ExoPlayer determines that the format exceeds the capabilities of the decoder and hence plays only the audio component.

If I force ExoPlayer to play the video stream regardless then it works fine, suggesting that the underlying platform should be reporting that it's capable of playing video in this format with larger decode widths, on Pixel at least.

  • Perhaps we should be more optimistic and have ExoPlayer always try and play the stream in the case there's only one stream available and it exceeds the device capabilities. We'll have a think about this.
  • You can experiment with force enabling the video stream for yourself by editing this part of TrackSelectionHelper so that the if block is always executed. You'll then be able to select the video stream in the demo app by clicking on the "Video" button.
  • As an aside, if you control the way these videos are encoded, I'd strongly recommend you use H264 instead.

@ojw28, so currently, is there a way to have ExoPlayer always try and play the stream in this case ?

Not currently. We're thinking about it, but it's unclear whether it makes sense.

Please could you:

  1. Check out the latest dev-v2 code.
  2. Try and play the affected video.
  3. Paste the output of adb logcat -s "MediaCodecInfo" here. You should see a bunch of lines containing "FalseCheck" the detail exactly why the stream wasn't played.

Thanks!

Add option to select track that exceeds renderer capabilities
7bbe213 
Leaving disabled by default for now, but we may want to consider
enabling it by default. Note that in V1 for ExtractorSampleSource
the behaviour was equivalent to this option being enabled, since
we didn't perform capabilities checks. For DASH/SS/HLS the V1
behaviour was equivalent to this option being disabled.

The type in PlayerActivity has been changed just to make it
easier to add a line that calls setParameters.

Try exceeding renderer capabilities by default
759cb32 
Not sure what I think about this, but we're getting quite
a lot of issues reported where streams play fine but capabilities
indicate they wont. It's probably best just to cross our fingers
and hope for the best in such cases, as was the case in V1 when
using ExtractorSampleSource.
