Can't open larger videos #90

Open miguelgomezmunoz opened 5 years ago

miguelgomezmunoz commented 5 years ago

Hi, I have an application that can open 12 videos simultaneously.

When using videos of 2-3 minutes it works good. However, when I try to open 12 videos with a duration of 1 hour (around 3 GB per video) it can only open 6 or 7 of them. The application does not crash, it just do not render the other videos. Is there any way of playing larger videos?

Happened something similar long ago, and it was solved improving the graphics card.

It seems to me like codec/graphic card issue, too. Are you able to open them with MPC-HC player? (Open 12 MPC-HC instances).

miguelgomezmunoz commented 5 years ago

Thank you for your answer, I have installed the MPC-HC player and I am able to open the 12 videos at the same time with this player.

I have a NVIDIA GeForce GTX 1080, if I go to its properties it says: Total Available Graphics Memory: 24510 MB Dedicated Video Memory: 8192 MB System Video Memory: 0 MB Shared System Memory: 16318 MB

Can you open 12 instances of your app with one large video only?

miguelgomezmunoz commented 5 years ago

If I open 12 instances, all videos are rendered

It seems like some limitation per process. Frankly, I have no clue what it may be. Check what filters/decoders do you use and try to ask authors of these filters.
