Record of A codec problem in Ti duati

I solved a problem with Ti codec last week. record it.

The problem is that, on the omap4430 platform, the 720 p and 60framerate Avi cards are played in the JB version, and a lot of frames are lost when reading logs. In general, this situation is caused by insufficient CPU resources, however, I see that the CPU usage is not very high. After reading the code for half a day, I don't know what's going on.

The reply from Ti is that the framerate they get is 30, not 60, and it is very strange, because omxcodec does not set the framerate, and finds the code of other projects, I was surprised that I didn't find anything. However, in order to cooperate, we set the framerate-related parameters. At the beginning, we only set the inputport parameter. The outputport parameter was not set. Later, Ti helped, the parameters of the two ports are set. It is really good, but there is no code for setting framerate-related items in Google's code, so the framework should not be modified, however, TI does not need to be modified. There is no way. If the project needs to be released, the framework can only be modified.

To sum up

1. I have some knowledge about the communication methods between omxcodec and omxcodec node. I used to only read this code and know how to use it when I encountered a problem. If I find a similar problem in the future, I also know how to dumpport related parameters.

2. I have little knowledge about video, and I don't know much about it. I will read more Code and related articles at work in the future.
