When playing the video, the error “The SourceBuffer is full, and cannot free space to append additional buffers” occurs, causing the video courseware to be unwatchable. How can this be resolved?

Hi there, the issue has already been reported to the technical staff~
Additionally, I just tried it, and the playback works fine on my browser. Could you try using a different browser to see if there is any difference?

Other courses can be played normally, but this lesson doesn’t work. I have also cleared the cache and logged in again.

Have you tried completely closing Chrome and then playing it again?

| username: TiDBer_URZVn12M | Original post link

Not working :frowning:

| username: Soline324 | Original post link

Got it, the technical colleagues will give you feedback after reviewing it~~~

Try checking Module 1 - Lesson 3 of this course: https://learn.pingcap.com/learner/course/120005.

I think the problem is that the tidb-server process is not running. You can check if the process is running using the ps command. If it is not running, you can start it using the systemctl start tidb command.

Is this the Huawei browser? How about trying Google or Firefox?

| username: TiDBer_URZVn12M | Original post link

I switched to a Microsoft Edge browser, but it still doesn’t work. It’s probably not related to the browser. It’s the same with Chrome.

For me, it works well, so it shouldn’t be a server issue.

Refer to this and try disabling hardware acceleration.

| username: TiDBer_URZVn12M | Original post link

Strange, even after disabling hardware acceleration and switching to Chrome, it’s still the same.

| username: TiDBer_URZVn12M | Original post link

Chrome has also disabled hardware acceleration.

Because I have seen it before and want to review it, I opened the course and the above image was displayed. Then, when I clicked on “relearn,” an error occurred, and it couldn’t be played.

After investigation by technical experts, the course settings are normal. It is considered that there may be personalized settings on the terminal. You can try resetting the browser.

| username: TiDBer_URZVn12M | Original post link

The course should be normal, but how do I clear this SourceBuffer? :sob:

| username: TiDBer_pkQ5q1l0 | Original post link

Refresh a few more times, it happens occasionally.

Try using a different browser.
