Multiple custom encodes, only one happening, the rest failing.

Post by SteUK »

Me again :)

My forked 4 encodes works a treat on my desktop (bog standard decent Intel i7 (8-logical-cores). But when I run it on a higher-end conversion machine (Xeon 48-logical cores) it only does one of the encodes with the error 'No video or audio found in media'.

Anyone seen anything like this?

Thanks!

Is the behaviour predictable? I.e. does it happen the same way every time?

Yes, exactly the same thing every time. Which I guess might suggest it isn't timing related.

They three go from 'Waiting for processor resources' in the job queue, to the 'No audio or video found in media' in the completed queue. Want me to send a video? Or the log files?

I am using a custom ffmpeg.exe (one I compiled up with the cube mapping conversion code additition). But I am 99% sure it isn't that as it works perfectly on my i7, and works fine for the one video it does convert.

I have tried adding the flag -threads 12 (to limit back the number of threads ffmpeg can use) as well. No change.

I tried putting a custom batch file command in before three of the videos (with waits of 3, 6 and 9 seconds respectively). No change.

Right...some more info...

I was trusting the test video I was provided with was 'good'. It isn't. Well, in the sense of what I need to test with it isn't. It contains only an audio stream, no video. I am pumping through one of my test videos now and the workflow behaves as I would expect.

Interesting that the mp4 with only an audio stream gives these odd results though...

Well, you could send me the mp4-file so i can test it. Maybe it has some strange data that FFAStrans cannot resolve. Also, does the same file exhibit same issue in your normal i7 working environment? In addition, make sure you custom built ffmpeg works the way it should independant of FFAStrans.
