FD64 900 Beta Cannot Play Certain MPEG-TS Files Smoothly While FD64 812 Can [CLOSED]

[tatemono]

I have observed that certain MPEG-TS files which are played smoothly using VLC on FD64 812 do not exhibit the same smooth playback when they are played with VLC on FD64 900 beta.
One of the aforementioned MPEG-TS files is available on the internet, and its URL is "https://tsduck.io/streams/italy-sardini ... mux4rai.ts".
Below, you can find a screenshot of VLC playing this MPEG-TS file on FD64 900 beta.

@tatemono, thank for your report. We are seeing mixed results on our hardware. What is you GPU? Can FD64 812 vlc play the test link for more than a minute?

I burned the ISO file of FD64 812 on one USB flash drive and burned the ISO file of FD64 900 Beta on another. The version of FD64 running on my PC depends on which USB flash drive I plug in when booting.

The GPU of my PC is integrated, part of an Intel CPU. For more details, please refer to the screenshot of the "system information" window below.

The duration of the MPEG-TS file downloaded from the test link is 33 seconds. FD64 812 VLC plays this MPEG-TS file smoothly. Playback will take more than a minute if the MPEG-TS file is played more than once.

@tatemono, can you please run vlc, passing the videos that cannot play, in a terminal with command
VDPAU_DRIVER= VDPAU_QUIRKS=AvoidVA vlc ... videofiles ... ?

I did the test you proposed and its 3 variants. Let me list the command to be run in each test as shown follows.

Code: Select all

[TEST 0]                                    vlc mux4rai.ts
[TEST 1] VDPAU_DRIVER=                      vlc mux4rai.ts
[TEST 2]               VDPAU_QUIRKS=AvoidVA vlc mux4rai.ts
[TEST 3] VDPAU_DRIVER= VDPAU_QUIRKS=AvoidVA vlc mux4rai.ts

Every test except [TEST 0] plays the MPEG-TS file smoothly on my PC running FD64 900 Beta.

After finishing [TEST 3], the output displayed on the screen is shown as follows.

Code: Select all

@tatemono, in summary: this issue will be fixed in the Final ISO. Until then you can fix it by editing /etc/profile.d/vdpau-va-gl.sh and commenting out the line that sets VDPAU_DRIVER (alternatively you can change the line to export VDPAU_DRIVER=).

This issue affects Intel GPUs. The error messages are unavoidable and insignificant as long as videos play OK, which they do now. Thank you for reporting this issue!
