4K video 60 frame video compression exception

[gaoyouhuang]

Hi, thanks for this great library!

Device: HUAWEI MAte 30 Pro 5G

4K video recorded with this phone

21603840,60 frames----> 7201280,30 frames,72012805 bit rate, 5 keyframes is fail but 21603840,30 frames----> 7201280,30 frames,72012805 bit rate, 5 keyframes is success

VideoTrackTranscoder#resizeDecodedInputFrame() methos In the decoding process, this method decoder.dequeueOutputFrame is greater than 0 for a total of 8 times

The device is OK. It supports 4K decoding and encoding because I can use other libraries https://github.com/MasayukiSuda/Mp4Composer-android

But I still don't know what's wrong. I hope I can get your help. thank you

Glad to hear you are enjoying LiTr! I will take a look at this. So is LiTr dropping frames and producing corrupt video? Or does transcoding fail and stop?

Yes, litr will compress successfully in the end, but the video is not complete

A 1-minute video during decoding decoder. Dequeueoutputframe > = 0 7 times Obviously, the video generated in this way is abnormal in the end

MediaCodecDecoder @Override public int dequeueOutputFrame(long timeout) { return mediaCodec.dequeueOutputBuffer(outputBufferInfo, timeout); } I see outputbufferinfo Size has always been 1, which is obviously not a normal data

Sorry, I can't analyze why at present

Hi, brother, Did you find out why?

Hi. Didn't get a chance yet, working on some new audio features. Will look into this next.

I am trying to reproduce it on Samsung Note 10 and 60 fps 4K video transcodes file for me. Can you send me a sample video that is failing for you? I am trying to see if there is a problem with video or a phone. What are your target parameters? Are you applying any filters?
