InsufficientCapacityException: Buffer too small (4177920 < 4845595) #11116

Closed sundaylol closed 1 year ago

sundaylol commented 1 year ago

When I try to play a 4K video with the following format on the rk3566 platform, I get a "buffer too small" error log which sometimes prevents playback. However, after seeing an "ACodec onOutputFormatChanged" log, the video can play normally. How can I solve this issue?

Does it only happen on the stated device, or also on other devices (e.g. a phone)?

Does it only happen on the stated device, or also on other devices (e.g. a phone)?

Please provide media we can use to reproduce this issue. Please either upload it here or send to dev.exoplayer@gmail.com using the subject Issue #11116. Please also update this issue to indicate you’ve done this.

It only happen on the rk3566 platform .Attach is the AvCodec.cpp ,and I have send the Video with email .The video file is very large, and because I used Permute3 to crop it, the video bitrate and resolution changed, so I can only send the original video. AvCodec.txt

Thank you for sharing the file us. Unfortunately, downloading was very slow and eventually failed due to network errors. Would you be able to host the file on some server and give us a direct link which we can pass directly to the player?

Aside, the error shows that MediaCodec is offering input buffers with size of approximately 4MB whereas the video has bigger samples. The player configures the max sample size when it creates the MediaCodec either based on the file, if the file headers specifies one, or using an approximation logic based on codec and resolution. From my experience though, devices do not necessarily follow the configuration and may decide to allocate either more or less space for each buffer.

I cannot tell at the moment which of the following happen in your case:

If we can try out the file, we can verify or eliminate the first two options. If you cannot share the file, I'll ask you to do some debugging to get to the bottom of this. Note that if it turns out that this is a device issue, there's not much that we do on the player side.

I cannot tell at the moment which of the following happen in your case:

  • the file specifies a max sample size that is incorrect, or
  • the player makes a calculation of max input size that is incorrect, or
  • the MediaCodec implementation on the device is not respecting the player parameters.

Thank you for your response. I have uploaded the original video to the cloud drive. https://drive.google.com/file/d/1-zRtCuweia35otM1rWaVbqETQmIAFxJi/view?usp=share_link Today, I tried several other devices such as mobile phones and tablets, but the problem did not occur on those devices. However, it is strange that when I use VideoView to play the video directly on the Rk3566 platform where the problem occurs, there is no such issue. Could you please help me to investigate the problem? Thank you very much.

Thank you for uploading the file. From the file itself, ExoPlayer picks that the maximum sample size is over 5MB and then ExoPlayer configures the codec with a higher max sample size, around 6MB. On a Pixel device, MediaCodec's input buffers are 7MB. I believe the problem you're facing is device specific and the device does not allocate big enough buffers for this content.

At this point, I think it will be more beneficial if you contact the device OEM and report this issue.
