问题
I am in the process of upgrading an app to android 6.0. Everything seems to be alright except when trying to play certain videos from a remote source. They play just fine on our non Marshmallow devices (for specifics, I have a Galaxy S3 on 4.1.2 Jelly Bean that's playing the exact same video just fine, no issues). We've tested with multiple devices on 6.0, and the problem seems to be localized to just this OS.
When trying to play a video in a simple videoview, I get an alert saying "Can't play this video".
I had some problems with other videos on 4.1.2 in the past, and thought it may be a codec issue, which I think again may be the culprit. The videos that won't play all have these in common:
- AAC
- H.264
- MPEG-4 SDSM
- MPEG-4 ODSM
When I try to launch the activity with the videoview, this is what the logcat spits out.

Is this a known problem with Marshmallow, or is this something wrong with the videos perhaps?
回答1:
Videos with ODSM / SDSM codecs can bypass being deinterlaced, but it appears Android Marshmallow will not recognize ODSM / SDSM codecs and will require the videos to be deinterlaced. Previous OS versions will not play videos that haven't been deinterlaced normally, with the exception being the video file including ODSM or SDSM codecs.
I believe this is due to Quicktime support issues, and may need to be opened as a defect with Android Marshmallow, but may also be intended by Google.
