C++ (Cpp) DecryptResult Examples

Example #1

File: ChromiumCDMProxy.cpp Project: Wafflespeanut/gecko-dev

RefPtr<DecryptPromise>
ChromiumCDMProxy::Decrypt(MediaRawData* aSample)
{
  RefPtr<gmp::ChromiumCDMParent> cdm = GetCDMParent();
  if (!cdm) {
    return DecryptPromise::CreateAndReject(DecryptResult(eme::AbortedErr, aSample),
                                           __func__);
  }
  RefPtr<MediaRawData> sample = aSample;
  return InvokeAsync(
    mGMPThread, __func__, [cdm, sample]() { return cdm->Decrypt(sample); });
}

Example #2

File: CDMProxy.cpp Project: NAndreasson/cowl-patches

void
CDMProxy::DecryptJob::PostResult(GMPErr aResult, const nsTArray<uint8_t>& aDecryptedData)
{
  if (aDecryptedData.Length() != mSample->Size()) {
    NS_WARNING("CDM returned incorrect number of decrypted bytes");
  }
  if (GMP_SUCCEEDED(aResult)) {
    nsAutoPtr<MediaRawDataWriter> writer(mSample->CreateWriter());
    PodCopy(writer->Data(),
            aDecryptedData.Elements(),
            std::min<size_t>(aDecryptedData.Length(), mSample->Size()));
  } else if (aResult == GMPNoKeyErr) {
    NS_WARNING("CDM returned GMPNoKeyErr");
    // We still have the encrypted sample, so we can re-enqueue it to be
    // decrypted again once the key is usable again.
  } else {
    nsAutoCString str("CDM returned decode failure GMPErr=");
    str.AppendInt(aResult);
    NS_WARNING(str.get());
  }
  mPromise.Resolve(DecryptResult(aResult, mSample), __func__);
