Something like the below log, when I enable the vlc messages:
core warning: picture is too late to be displayed (missing 1455 ms)
avcodec debug: enabling direct rendering
avcodec warning: plane 0 not aligned
avcodec warning: disabling direct rendering
core warning: picture is too late to be displayed (missing 1446 ms)
core warning: picture is too late to be displayed (missing 1434 ms)
core warning: playback too early (-62177): down-sampling
avcodec debug: enabling direct rendering.
And also similarly for the audio:
playback way too early (-122000): playing silence
I want to detect them from the vlc application, without looking at the
video so to save some time.
Is there any api that I could use to parse them mp4 and detect for such flaws ?
