Validating IMF packages with subtitle tracks #147

Closed pfirth3 closed 7 years ago

pfirth3 commented 7 years ago

I am having trouble getting a successful validation result when trying to analyze any IMF package that contains a subtitle track. The errors/warnings I get are related to the IMPAnalyzer saying that a CPL resource is not present in the package and that an essence descriptor does not have a match in any track file. Based on a test I did with the IMFTrackFileReader, Subtitle essence does not come up as a supported type. It says the only supported types are MainImageEssence, MarkerEssence, MainAudioEssence. Are subtitle tracks really not currently supported? If so, when will support be added?

Photon does not support subtitle track currently but we do have a plan to add this support in near-term. We will provide you more accurate timeline once we have the data available.

We have added basic support for subtitle sequence in version 4.2.3. This should address essence descriptor related error with subtitle sequence.
