add missing output formats to GStreamer mapping

[mdimopoulos]

• missing formats are GRAY12LE, YUV444P14LE, YUV444P16LE, GBRP, GBRP10LE, GBRP12LE, GBRP14LE

@ndufresne here i have added the missing output formats so that GStreamer decoders can map them correctly.

I encountered 2 issues though where i could use your help.

I did not find matches for GRAY12LE, YUV444P14LE and GBRP14LE (i searched in https://gstreamer.freedesktop.org/documentation/video/video-format.html?gi-language=c). The last 2 are not important for AV1 (i think they are related to H.265 or H.266), however GRAY12LE does affect quite a lot of test vectors in AV1 argon test suites. Do you happen to know which is the equivalent format in GStreamer (if there is one)?

Related to the above there is 1 example where it's seen that 2 elements do not know how to handle this format, which is expected since it does not exist i guess (at least not as GRAY12_LE)
gst-launch-1.0 --no-fault filesrc location=/home/mdimo/test/fluster/../resources/AV1-ARGON-PROFILE2-NON-ANNEX-B/argon_coveragetool_av1_base_and_extended_profiles_v2.1/profile2_not_annexb_special/streams/test22.obu ! av1parse ! av1dec ! video/x-raw ! videoconvert dither=none ! video/x-raw,format=GRAY12_LE ! videocodectestsink -m WARNING: erroneous pipeline: could not link videoconvert0 to videocodectestsink0, neither element can handle caps video/x-raw, format=(string)GRAY12_LE

videocodectestsink cannot handle formats GBR_12LE and GBR (confirmed by the docs https://gstreamer.freedesktop.org/documentation/debugutilsbad/videocodectestsink.html?gi-language=c). Which is the best way to request this as a feature in GStreamer project? Due to this we currently have quite a lot of errors with AV1 argon test suites.

By the way, when running ./fluster.py r -d GStreamer-AV1-libaom-Gst1.0 -ts AV1-ARGON-PROFILE2-NON-ANNEX-B -s with GStreamer 1.26.5 i get 15/150 passes (they should be 42).
After including unhandled output formats to videocodectestsink and fixing md5 checksums (without all layers), i expect the number to be close to the expected one.

Some formats are missing in the 12bit space, but shouldn't prevent mapping the others for now, we should fail elegantly though.

[mdimopoulos]

Actually none of the formats i am adding in this PR are supported by videocodetestsink, so i will have to park it for now. I will create a new PR that will contain only the exception handling.

[ndufresne]

Even if missing in gst, the mapping/naming all looks right, so it could be added, I'll take care of adding the missing bits afterward.

[ndufresne]

Does not exist, yet.

Does not exist, yet.

[ndufresne]

This one exists, but not in videocodectestsink yet.

[ndufresne]

14bit is missing, others missing videocodectestssink.

Ok.
