Same Command is not working on React-Native-ffmpeg #1035

Open aza1200 opened 2 months ago

aza1200 commented 2 months ago

Hello,

I am using react-native-ffmpeg-kit to encode a video with the following FFmpeg command:

ffmpeg -i input.mp4 -c:v hevc_videotoolbox -c:a aac -tag:v hvc1 -vf scale=1920:1080 -b:v 3000k -r 30 -movflags +faststart -y output.mp4

It works on local mac - ffmpeg(not-native-ffmpeg-kit) However, when I run this command on react-native ios simulator, I receive the following error message:

Environment: FFmpeg version: 60.3.100 (via react-native-ffmpeg-kit) H.264 codec, 30 fps, 1220 kbps Command options: Video codec: hevc_videotoolbox Resize: 1920x1080 Video bitrate: 3000k Frame rate: 30 fps Audio codec: aac Other: -movflags +faststart Issue: It seems there’s an issue with the encoder (hevc_videotoolbox) while initializing the output stream. The error message suggests that the problem might be related to incorrect parameters, but I’m not sure which parameters are causing the issue (bitrate, resolution, frame rate, or something else).

Has anyone experienced this issue before? Any help or insights on how to resolve this would be greatly appreciated!

Thank you in advance!

If there is a difference in behaviour, then outputs from local ffmpeg and react-native-ffmpeg-kit must be compared to understand the issue.
