Decoded file runs too fast

Hi,

i have a problem rendering my video file. My application is capturing samples from a webcam,

decoding these samples/images(NV12 -> RGB32) for further processing and then encodes them (H264) before writing to disk.

My main problem is when i load this encoded video file back into my application, the frame rate is off meaning the video is playing way too fast.

I am using SourceReader(Asynchronous) to do the acquisition/decoding and SinkWriter for encoding and writing to disk.

I have tried do set all attributes so that the media type matches the one who was used for writing the video file in the first place but still no luck. Am i responsible to do the timing? Any tips what i could do?

When i load the file with MediaPlayer or VLC everything is fine.

Greetings,

Dosfried
