With http://www.shlomifish.org/Files/files/video/We%20Found%20Love%20-%20Rihanna%20%28Cover%20by%20Tiffany%20Alvord%20Feat%20Andy%20Lange%29-I2YzhhCXX2Y.mp4 which was downloaded from https://www.youtube.com/watch?v=I2YzhhCXX2Y using youtube-dl , I am getting this:

and the video won't play. VLC XCB or mpv --vo vdpau seem to play it fine. I am using vlc-2.2.4-8.mga6 and lib64vdpau-va-gl1-0.4.1-1.mga6 on Mageia Linux x86-64 v6 on a Core i3 machine with Intel Graphics.

source video chroma type not supported

libvdpau-va-gl have only 4:2:0 chroma type implemented. If video has 4:2:2 or 4:4:4, it won't work.

Howerever, I've just tried to download video (link), and play it in VLC 2.2.4. It plays fine. Tracing shows that VDPAU code is actually used, for both decoding and rendering.

shlomif commented 8 years ago

@i-rinat : it's strange that you can play it fine. What are your system specs (hardware, OS, distro, versions)? And how did you build VLC?

i-rinat commented 8 years ago

I'm testing on notebook with Intel i7-3632QM, it has embedded graphics named "HD Graphics 4000". Debian testing. VLC 2.2.4-4 from Debian repository.

i-rinat commented 8 years ago

Also try to run VLC with environment variable VDPAU_TRACE=1 enabled. As name suggests, it will enable VDPAU calls tracing.

@i-rinat - thanks for the VDPAU_TRACE tip - here is the output I got:

I had 1920x1080 hardcoded as maximum resultion since the beginning. Actual detection wasn't implemented, but it was fine all the time.

Now, from looking into VLC source code I can tell that it not only checks for supported chroma type, but also checks whenever supported resolution is enough for the current video. If one of the checks fail, "chroma type" is considered unsupported.

Now when I think about it further, I realize, that 1920x1080 could be not sufficient. Video codecs often have restrictions on width and height of an encoded frame. Often dimensions should be multiple of a small number. 4, 8, or 16, for example. When video encoded, frame is enlarged to fit requirements. During decoding process remainders are cut, and resulting frames have the same resolution as input ones. So it could be that 1920x1080 video internally have a larger resolution, but that's hidden. If so, that check will fail. (But it didn't fail when I tested. I don't know what happens there.)

Anyway, I've changed resolution to 4096x4096 in 1dc6bdb7965dd09d6c706540a438ced442fa3d2c just to be sure.

Could you check whenever libvdpau-va-gl built from master branch is working with VLC now, please?

@i-rinat : I've now compiled and checked it and with:

shlomif@telaviv1:~/Music/mp3s$ export LD_LIBRARY_PATH=/home/shlomif/apps/to-del-vdpau/lib/vdpau/ VDPAU_DRIVER_PATH=/home/shlomif/apps/to-del-vdpau/lib/vdpau/
$ strace -f -o ~/vlc.strace vlc --vout vdpau We\ Found\ Love\ -\ Rihanna\ \(Cover\ by\ Tiffany\ Alvord\ Feat\ Andy\ Lange\)-I2YzhhCXX2Y.mp4 2>&1 | tee ~/vlc.txt

seems to play the video fine, and I checked in /proc/pgrep vlc/maps that the right vdpau-va-gl shard-lib was loaded. Thanks for the fix and I'm looking forward to a new release with it.

i-rinat commented 8 years ago

Doesn't look like that I'm going to do any other changes in the nearest future. So I've put v0.4.2 release tag.

shlomif commented 8 years ago

@i-rinat: many thanks for the new release! I'll package it for Mageia v6. Thanks for all your help, and here is a link to a photo of a cute kitten in gratitude (Safe-for-work/SFW) - http://imgur.com/NmQOgTH .

The new release seems to be working fine, so I'm closing this issue as fixed. Thanks again!
