Subject: [PATCH 18/39] codecs: nvv4l2: align encoder plane width to 64B
|
|
|
|
Transformations of Block linear formats to linear Pitch formats are done in HW.
|
|
|
|
VIC is responsible for that and has the limitation that width must be aligned to 64 Bytes.
|
|
|
|
This allows the encoder to work with every single non standard resolution, effectively bringing full support to any video.
|
|
|
|
That is particularly important on streaming software that use ffmpeg for encoding which many times can be weird resolutions (e.g. pip).
|
|
|
|
The output encoded frame has the original line width of course.
