When I use the hevc_videotoolbox encoder in ffmpeg it always prompts me the same error
18 février 2023, par 张益铭when i use


ffmpeg -i BabyShark.mp4 -c:v hevc_videotoolbox -b:v 6000k BabyShark1.mp4



it always returns an error like




[hevc_videotoolbox @ 0x7fec79206e00] Error encoding frame : -12905
[hevc_videotoolbox @ 0x7fec79206e00] popping : -542398533 Error
initializing output stream 0:0 — Error while opening encoder for
output stream #0:0 - maybe incorrect parameters such as bit_rate,
rate, width or height [aac @ 0x7fec79208a80] Qavg : 13693.864 [aac @
0x7fec79208a80] 2 frames left in the queue on closing Conversion
failed !




but


ffmpeg -i BabyShark1.mp4 -c:v h264_videotoolbox -b:v 6000k BabyShark2.mp4



works fine.


Other tutorials say that the above error is a problem of out-of-sync audio and video
But I changed a lot of videos, the error still appears, even the videos I recorded myself.
How can i fix it.


My computer model is MacBook Pro 2019
I want to use GPU to convert video to H265 encoding


Same problem with a computer using another M1 chip With GPU

ffmpeg not finding system/speaker audio device
6 octobre 2022, par user4609276I'm trying to screen record with audio, and the video portion is fine but I can't record audio because ffmpeg can only find my microphone, but not my speaker/system audio.


[AVFoundation indev @ 0x135f046a0] AVFoundation video devices:
[AVFoundation indev @ 0x135f046a0] [0] FaceTime HD Camera
[AVFoundation indev @ 0x135f046a0] [1] Capture screen 0
[AVFoundation indev @ 0x135f046a0] AVFoundation audio devices:
[AVFoundation indev @ 0x135f046a0] [0] MacBook Pro Microphone



Python Code


os.system(f"""ffmpeg -f avfoundation -video_device_index 1 -i "default:none" -t 00:00:05 -y -r 10 recording{x}.mov""")



Is there a reason why it's not picking up the system audio ? I tried looking around and struggling to find an answer.


Thanks in advance

Windows phone 8 neon inline assembly ffmpeg [duplicate]
5 février 2013, par user2036635Possible Duplicate :
windows phone8 wp8 arm neon assemblyI am about to transplant a project just like ffmpeg onto wp8(ARM). Unfortunately, most part of the project was written by arm neon inline assembly code (NEON inline assembly) with AT&T format..
Any suggestion about tools or methods to quickly doing that ? Or what should I do for that ?
I asked this question before but closed for the reason which is not constructive but I do not think so because what I mentioned is INLINE assembly with AT&T.
Any suggestion would be appreciated.
