No usable video on [Orange PI PC+] using VLC

[laurentppol]

Hi there,

my favourite Video player is VLC (who remembers? ;p), so I downloaded it,

apt-get install vlc

 

But on MP4 video image is 8x squashed, speed looks OK,

sound is "almost working" with muting from time to time.

 

 

With mvp screen looks (geometrically) ok, but pixels are 8x8 (colour).

Unusable too.

 

Any ideas?

 

Sample film visualises on mCeleron 1.4GHz / Intel GMA w/o problem. (I know, from HDD, but it looks not like a HDD performance problem).

Is the same video working with preinstalled mpv?

The VLC problem could be a bug in libvdpau-sunxi, can you try if this branch fixes it?

 

mpv should work, if not, what do you mean with "pixels are 8x8"? Maybe post a picture too.

git clone / configure / Make "as usual"? Are kernel headers installed "by default"?

If this above is from mpv, it's look like the known bug in divx/xvid video, which is not supported from vdpau except nVidia hardware. The solution in mplayer for me was to add supported codecs in configuration - /usr/local/etc/mplayer/mplayer.conf :

vc=ffmpeg12vdpau,ffh264vdpau,ffhevcvdpau,

Comma at the end is important and do the trick. In mpv was something similar, but i don't remember the exact line. Originally configuration should look like this - /usr/local/etc/mpv/mpv.conf (/etc/mpv/mpv.conf in Xenial) :

hwdec-codecs=all

You have to replace "all" with list of supported codecs, with comma at the end.

For VLC i have no idea. Somehow you have to deny ffodivxvdpau of using, or add possibility of using alternative codecs for mpeg4, but i am not sure there is an option for this in VLC.

libvdpau-sunxi can be compiled with make and make install (as root), as it is written in the README.

 

The mpv output could indeed be a problem with mp4, as RangerBG already said. The mp4 codec is pretty bad in libvdpau-sunxi, many variants might not work correctly. You should try a known working one like Big Buck Bunny to be sure it works as expected.

hi there, I am trying to play /dev/video0 with mpv with vdpau (on Orangepi Lite). But it always fails with:

Video filter chain:
[in] 640x480 yuv420p[nv12] bt,601/limited CL=unknown <---
[out] ???
Falling back to software decoding. 

I tried vdpau in vlc but time is moving but I do not see any video.

Any idea please?

Compiling wasn't hard on Fedora(Redhat), lets try on debian ;p
