Regression from closed source: Many 0-length frames in decoding #23

Open colintheshots opened 8 years ago

colintheshots commented 8 years ago

The open source media for mobile library appears to regress from the old JAR we had. On transcoding using my Nexus 6, we're finding many video frames are now decoded as 0-length. The final, transcoded video then has many dropped frames and the audio presentation timestamps go backwards at each dropped frame. Reverting to the JARs of version 1.2.2675 fixes this regression for us.

We cannot easily pinpoint the source of this regression because the open source library was committed without history.

Thank you for reporting this issue, we will take a look at it. Could you clarify the origin of the input video stream? Was it recorded using phone's camera or copied from other source? If you could share the stream, it would help.

Yes, we simply imported the video from an mp4 movie file. I'll attach it. VidkuHQsnowstorm.mp4.zip

For parameters, we were changing the video from 1080x1920 to 720x1280. Rotation 0.
