Description Georg Ottinger 2018-06-26 07:49:46 UTC
FYI: I started work on basic AV1 Support for ivfparse.

This work is part of a GSOC 2018 project, mentored by Intel Media And Audio For Linux

adds AV1 support to gstivfparse.c

with this patch bascially adds the AV01 FOURCC to the list of allowed IVF Media.

At a later point dynamic resolution change can be supported - therefore the sequence header OBU and frame header OBU of AV1 file must be parsed - which can be done in future with the help of gst-lib gstav1parse.

Makes sense but please provide this as a "git format-patch" style patch :) See https://gstreamer.freedesktop.org/documentation/contribute/index.html#how-to-submit-patches

Review of attachment 372834 [details] [review]:

for sake of good practices, the subject line should have the format:

element: description

Also, the subject should have a recommended length of 50 chars and the body should wrap at 72 chars:

https://chris.beams.io/posts/git-commit/#seven-rules

Finally, at the end of the commit log, it should be the URL of this bug, for further reference.

    ivfparse: Add the AV01 FOURCC for parsing AV1 IVFs
    
    Adds AV01 FOURCC to the list of allowed media files, in order to allow
    parsing the IVF Container holding AV1 content.
    At a later point dynamic resolution change can be supported - therefore
    the sequence header OBU and frame header OBU of AV1 file must be parsed,
    which can be done in future with the help of gst-lib gstav1parse.
