6 years ago - Codec re-initialization shouldn't result in a black screen flash. Is this issue specific to the Amlogic device, or can you reproduce on all devices? If it's device specific, you'll need to report the problem to the device manufacturer. If it's not device specific, please provide us with concrete reproduction steps, including sample media that reproduces the issue.
- You shouldn't need to do anything special to the shutter view for this use case. It should work as-is.

Issue description
“Transitions between sources are seamless. There is no requirement that the sources being concatenated are of the same format (e.g. it’s fine to concatenate a video file containing 480p H264 with one that contains 720p VP9).” - Medium
when videos change from .mp4 to .mp4 are seamless. But it is not seamless when change videos from .webm to .mp4. The result will be “reinitialize codec and cause a black screen flash.”
Reproduction steps
By using demo application (already taken care shutterview set to INVISIBLE) to test seamless between vp9 and avc format. In media.exolist.json:
"playlist": [ { "uri": "/sdcard/Movies/4k.mp4" }, { "uri": "/sdcard/Movies/4k.webm" } ] it will always return TRUE in:
boolean areAdaptationCompatible(boolean codecIsAdaptive, Format first, Format second) { //run-time info: // exoplayer version release-v2 // codecIsAdaptive=true // first.sampleMimeType=”video/x-vnd.on2.vp9" // second.sampleMimeType="video/avc”
return first.sampleMimeType.equals(second.sampleMimeType) … => TRUE }
and the result is “reinitialize codec and cause a black screen flash.” (not seamless)
