Changes to Buffer Size for Sunbird video player

[pushpamtrigyn]

Hi,

We had been testing the sunbird video player which is connected to Oracle streaming services for DIKSHA. However, due to certain issues while playing the video some errors start to come while rendering them. Oracle team suggested some changes to the buffer configuration which we had provided to them (specifically videoJS) :-

var Config = {
GOAL_BUFFER_LENGTH: 20, // reduced from 30
MAX_GOAL_BUFFER_LENGTH: 40, // reduced from 60
BACK_BUFFER_LENGTH: 20, // reduced from 30
GOAL_BUFFER_LENGTH_RATE: 1,
INITIAL_BANDWIDTH: 2097152, // reduced to 2 MB/s
BANDWIDTH_VARIANCE: 1.3, // slightly increased
BUFFER_LOW_WATER_LINE: 5, // increased from 0
MAX_BUFFER_LOW_WATER_LINE: 20, // reduced from 30
EXPERIMENTAL_MAX_BUFFER_LOW_WATER_LINE: 16,
BUFFER_LOW_WATER_LINE_RATE: 1,
BUFFER_HIGH_WATER_LINE: 20 // reduced from 30
};

Although we have modified them in sunbird video player and published our own package, the changes does not seem to be reflected. Is there any other way to explicitly set them in the codebase ? We modified these at the following paths before publishing our own npm package:-

Instances of videoJS are also found in player (Sunbird ED portal) but we are not sure whether to modify them.

Any leads and guidance on the same will be fruitful for us. Thanks !!

@pushpamtrigyn are these changes of the config updated in video js and are we using that modified videojs as a dependency in Sunbird video player since video js is a dependency it might get replaced. Check this and let us know.

@samarthnigam As we discussed , it's crucial to update the configuration at the appropriate location to observe the desired changes in player behavior for streaming. Based on your implementation, you have the option to configure either within the player or within the container (portal/mobile app).
