FFmpeg Convert Error Too many packets buffered for output stream 0:1.

[mcachirag]

I just simply convert one file to other and i got error from ffmpeg "Too many packets buffered for output stream 0:1."

here is the command i use.
-y -i /storage/emulated/0/videos/video6.mp4 -preset ultrafast -strict -2 -c:v libx264 -c:a aac -pix_fmt yuv420p /storage/emulated/0/DCIM/VideoEditorVideo/video6.mp4

i am able to convert other file with same command only for some video i got error.

Please help to resolve this.

#128

[FallingSnow]

Are you guys using the latest version of ffmpeg?

What does ffmpeg -version return?`

[invisiblek]

@FallingSnow when I wrote the patch a few months back I was using the latest ffmpeg available in arch repos at that time. For reference: #91 (comment)

I haven't tried h265ize without my patch since then. If it's been fixed in upstream ffmpeg, I wouldn't know.

[FallingSnow]

My first preliminary search lead to results that this bug had been fixed long ago. Please ensure your ffmpeg versions are up to date.

I have a similar issue. I am not sure if the root cause is related, but the error message was very similar, so I will put it in here for reference. I originally noticed the issue today with ffmpeg 4.1, but just to be safe, I grabbed zeranoe's static win-x64 build for 4.2.

(Note: the pasted stdout stuff below is still from 4.1, but I have verified that they are essentially equal when running with 4.2).

I was trying to h265ize a timelapse recording from my GoPro Hero7. In my case, the problem seems to be revolving around data streams that GoPro has injected.

However, I was able to work around this issue by first just running ffmpeg myself with a simple ffmpeg -i source.mp4 -c:v copy -an dest.mkv and then let h265ize work on that instead. (Since it was a timelapse, there was no audio stream.)

This is probably a weird edge case that might not even be h265ize's fault, stemming from either the mp4 container or the data streams that ffmpeg is not very pleased about. I personally assume it is the latter, but I have not done extensive trials. In that case, it might be worthwhile to add cli options to whitelist/blacklist certain streams?

Got the same issue fixed by setting -max_muxing_queue_size 1024 after file name
