Hmm, not sure what the problem might be here. Would you please verify that C:\Users\n\Desktop\h264\test\1532667754113 plays in VLC? C:\Users\n\Desktop\h264\test\1532667754113 should be an Annex B bitstream. What kind of file is C:\Users\n\Desktop\h264\test\1532667754113?

sannies commented 6 years ago

The H264TrackImpl didn't correctly parse the Sample objects from the file as it didn't set the SampleDescription thus it could set the sample derscription index correctly when writing the MP4. I published 1.9.36 with that fix.
