Bug 1494178 - Add check to ChromiumCDMChild to mark samples with 0 encrypted bytes as unencrypted. r=cpearce With the addition of an explicit encryption enum for CDM10 input data, if a sample has 0 encrypted bytes it must be marked as unencrypted. Historically we could let the CDM figure out based on the unencrypted + encrypted bytes. However, if we mark a sample as encrypted but it has 0 encrypted bytes, the CDM will fail to decrypt. This changeset adds a check to gracefully handle samples that are marked as encrypted but with no encrypted ranges. In such cases we mark the data as unencrypted and log that such data was encountered. This means we don't break playback of encrypted media should we overlook such cases, but have better detection via logging. Differential Revision: https://phabricator.services.mozilla.com/D6873
