Abstract

Methods, systems, and apparatuses may encode a media content item based on metadata from previous encoding. The encoding may also generate encoding metadata, which may comprise a qualitative or quantitative characterization of the encoded media content item. A prediction engine may, based on this metadata, determine new encoding settings for the same or a different video resolution. The prediction engine may cause an encoded media content item to be stored and may cause encoding of the media content item using the new encoding settings.

First claim

The invention claimed is:

1. A method comprising:
receiving, by a computing device, first metadata indicative of encoding of a media content item at a first resolution and in accordance with a first Quantization Parameter (QP);
determining, based on the first metadata and different metadata indicative of one or more other encodings of the media content item, a metadata trend;
determining, based on a quality of the encoding of the media content item at the first resolution and in accordance with the first QP, to encode the media content item at a second resolution, wherein the second resolution is higher than the first resolution;
determining, based on the metadata trend and based on the determining to encode the media content item at the second resolution, a second QP for encoding the media content item at the second resolution; and
sending, to an encoder, an indication of the determined second QP for encoding of the media content item at the second resolution.

2. The method of claim 1 , further comprising:
determining, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, a third QP for encoding the media content item at the second resolution; and
sending an indication of the determined third QP for encoding the media content item at the second resolution.

3. The method of claim 1 , further comprising:
determining, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, that a quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized; and
sending, based on the determining that the quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized, an indication of a different QP for encoding the media content item at the second resolution.

4. The method of claim 1 , further comprising:
determining, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, that a quality of the media content item encoded at the second resolution and in accordance with the second QP is optimized; and
sending, based on the determining that the quality of the media content item encoded at the second resolution and in accordance with the second QP is optimized, an indication of a new QP for encoding the media content item at a third resolution higher than the second resolution.

5. The method of claim 1 , further comprising:
determining, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, that a quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized; and
sending, based on the determining that the quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized, an indication of a lower QP for encoding the media content item at the second resolution.

6. The method of claim 1 , further comprising:
sending, to a second encoder different from the encoder, and based on second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, an indication to encode the media content item.

7. The method of claim 1 , further comprising:
determining, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, a third QP for encoding the media content item at a third resolution higher than the second resolution; and
sending the determined third QP for encoding the media content item at the third resolution.

8. The method of claim 1 , further comprising:
determining, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, that a quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized; and
sending, based on the determining that the quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized, an indication of a lower frame rate for encoding the media content item at the second resolution.

9. The method of claim 1 , wherein the determining the metadata trend is further based on encodings of a second media content item.

10. A computing device comprising:
one or more processors; and
memory storing instructions that, when executed by the one or more processors, cause the computing device to:
receive first metadata indicative of encoding of a media content item at a first resolution and in accordance with a first Quantization Parameter (QP);
determine, based on the first metadata and different metadata indicative of one or more other encodings of the media content item, a metadata trend;
determine, based on a quality of the encoding of the media content item at the first resolution and in accordance with the first QP, to encode the media content item at a second resolution, wherein the second resolution is higher than the first resolution;
determine, based on the metadata trend and based on the determining to encode the media content item at the second resolution, a second QP for encoding the media content item at the second resolution; and
send, to an encoder, an indication of the determined second QP for encoding of the media content item at the second resolution.

11. The computing device of claim 10 , wherein the instructions, when executed, further cause the computing device to:
determine, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, a third QP for encoding the media content item at the second resolution; and
send an indication of the determined third QP for encoding the media content item at the second resolution.

12. The computing device of claim 10 , wherein the instructions, when executed, further cause the computing device to:
determine, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, that a quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized; and
send, based on the determining that the quality of the media content item encoded at the second resolution and in accordance with the second QP is not optimized, an indication of a different QP for encoding the media content item at the second resolution.

13. The computing device of claim 10 , wherein the instructions, when executed, further cause the computing device to:
determine, based on the metadata trend and second metadata indicative of encoding of the media content item at the second resolution and in accordance with the second QP, that a quality of the media content item encoded at the second resolution and in accordance with the second QP is optimized; and
send, based on the determining that the quality of the media content item encoded at the second resolution and in accordance with the second QP is optimized, an indication of a new QP for encoding the media content item at a third resolution higher than the second resolution.
