[iOS] How to output Chinese file name?

[cimonk]

I use this command to do merge video file:
-y -f concat -safe -1 -i "/Users/XXX/Library/Developer/CoreSimulator/Devices/9B0CC62F-D424-42D2-93E9-7D9FF672B29E/data/Containers/Data/Application/F07EE09F-A82D-4F3C-AC79-819005BDBD44/tmp/【K萌君】教你做Windows+Ubuntu双系统.txt" -c copy -bsf:a aac_adtstoasc /Users/XXX/Library/Developer/CoreSimulator/Devices/9B0CC62F-D424-42D2-93E9-7D9FF672B29E/data/Containers/Data/Application/F07EE09F-A82D-4F3C-AC79-819005BDBD44/Documents/Downloads/20200306_141905981.mp4

But ffmpeg output the error log:

The log seems it could not set UTF-8 or unicode argument.

Please help, thanks.

Me too. I have tried again and again.

How did you find "/Users/XXX/Library/Developer/CoreSimulator/Devices/9B0CC62F-D424-42D2-93E9-7D9FF672B29E/data/Containers/Data/Application/F07EE09F-A82D-4F3C-AC79-819005BDBD44/tmp/【K萌君】教你做Windows+Ubuntu双系统.txt" path?

What happens if you add 【K萌君】教你做Windows+Ubuntu双系统.txt as a resource in your application try to use it as a resource?

[xwal]

@tanersener I run code with Swift:

MobileFFmpeg.execute("-i \'/var/mobile/Containers/Data/Application/0CE7F4A0-4A4C-45D8-914F-55A01DA9EA9F/Documents/Audios/百花香 - 魏新雨.aac\' -i \'/var/mobile/Containers/Data/Application/0CE7F4A0-4A4C-45D8-914F-55A01DA9EA9F/Documents/Audios/一个人挺好 - 孟颖.aac\' -filter_complex \'[0:0] [1:0]  concat=n=2:v=0:a=1 [a]\' -map [a] /private/var/mobile/Containers/Data/Application/0CE7F4A0-4A4C-45D8-914F-55A01DA9EA9F/tmp/022025FB-278F-4861-8531-24A693D4CCCB.aac")

I get an errror like this in debug area.

ERROR: /var/mobile/Containers/Data/Application/0CE7F4A0-4A4C-45D8-914F-55A01DA9EA9F/Documents/Audios/~±ô - O∞Ë.aac: No such file or directory

How can I solve it? Thanks.

[tanersener]

Your issues are not about the library, they are about accessing files with Chinese characters in iOS/tvOS.

I don't have experience with Chinese characters. So I don't have an idea about the fix. Did you try searching for solutions on stackoverflow?

I think you need to try to access those files using a source block like the following one. Did you try that?

NSString* path = [[NSBundle mainBundle] pathForResource:@"filename" ofType:@"extension"];
NSLog(@"path is %@",path);

How about iOS Swift use MobileFFmpeg.execute() with Chinese characters?

BTW, my android colleague can use their MobileFFmpeg library to execute with Chinese characters successfully.

NSString* path = [[NSBundle mainBundle] pathForResource:@"filename" ofType:@"extension"];
NSLog(@"path is %@",path);

I searched that iOS and FFmpeg with Chinese characters, but I didn't find about it.

I also tried it as below, but it does not work too.

NSString* path = [[NSBundle mainBundle] pathForResource:@"filename" ofType:@"extension"];
NSLog(@"path is %@",path);

I found this problem in function + (NSArray*)parseArguments: (NSString*)command , if use unicode char take from Chinese characters, it will take error in this line code char currentChar = [command characterAtIndex:i];.
If I use MobileFFmpeg.execute(withArguments:) function, It will work perfect because commandCharPArray[i + 1] = (char *) [argument UTF8String]; to UTF8 characters.

[tanersener]

@chaoskyme Thanks for the analysis. Apparently, there was a bug about parsing unicode parameters in MobileFFmpeg.parseArguments function. I fixed that on development branch. It will be included in the next release.

Please use MobileFFmpeg.executeWithArguments method until the fix is released.

[cimonk]

Yes!
MobileFFmpeg.executeWithArguments is work!
Thank you @tanersener @chaoskyme !!
