Transcoding multiple HLS outputs causes corruption in m3u8 index filename

[ehollander]

Summary of the bug:Encoding 1 input file to 4 different outputs causes 2nd and 3rd m3u8 index filenames to be corrupt (additional junk characters appended) on Windows 10. (Input file was a large 4K video)
How to reproduce:
issue the following command on Windows 10:

ffmpeg -i %video% -c:v libx264 -profile:v high -level 3.1 -s 1920x1080 -b:v 800k -maxrate 800k -bufsize 2M -flags +cgop -g 600 -hls_list_size 0 -hls_time 10 -f hls %folder%/out0800_.m3u8^
 -c:v libx264 -profile:v high -level:v 3.1 -s 1920x1080 -b:v 1000k -maxrate 1000k -bufsize 1M -flags +cgop -g 30 -hls_list_size 0 -hls_time 10 -f hls %folder%/out1000_.m3u8^
 -c:v libx264 -profile:v high -level:v 3.1 -s 1920x1080 -b:v 1500k -maxrate 1500k -bufsize 1M -flags +cgop -g 30 -hls_list_size 0 -hls_time 10 -f hls %folder%/out1500_.m3u8​^
 -c:v libx264 -profile:v high -level:v 3.1 -s 1920x1080 -b:v 2500k -maxrate 2500k -bufsize 1M -flags +cgop -g 30 -hls_list_size 0 -hls_time 10 -f hls %folder%/out2500_.m3u8​

[Steven Liu]

try as this command:

ffmpeg -i in.ts -b:v:0 1000k -b:v:1 256k -b:a:0 64k -b:a:1 32k \
  -map 0:v -map 0:a -map 0:v -map 0:a -f hls -var_stream_map "v:0,a:0 v:1,a:1" \
  -hls_segment_filename 'file_%v_%03d.ts' out_%v.m3u8

[ehollander]

Sorry but how does that help? Your taking as input a *.ts which is completly different than the goal of the command I was asking about. In my case I am taking in an mp4 and transcoding it to an HLS file.

[Carl Eugen Hoyos]

Pleas provide an actual command line without variables but using testsrc2 and sine as input and provide the command line together with the complete, uncut console output to make this a valid ticket.

[ehollander]

ffmpeg -i testsrc2.mp4 -c:v libx264 -profile:v high -level 3.1 -s 1920x1080 -b:v 800k -maxrate 800k -bufsize 2M -flags +cgop -g 600 -hls_list_size 0 -hls_time 10 -f hls c:/users/name/documents/video/out/out0800_.m3u8

-c:v libx264 -profile:v high -level:v 3.1 -s 1920x1080 -b:v 1000k -maxrate 1000k -bufsize 1M -flags +cgop -g 30 -hls_list_size 0 -hls_time 10 -f hls c:/users/name/documents/video/out/out1000_.m3u8
^{-c:v libx264 -profile:v high -level:v 3.1 -s 1920x1080 -b:v 1500k -maxrate 1500k -bufsize 1M -flags +cgop -g 30 -hls_list_size 0 -hls_time 10 -f hls c:/users/name/documents/video/out/out1500_.m3u8​}
-c:v libx264 -profile:v high -level:v 3.1 -s 1920x1080 -b:v 2500k -maxrate 2500k -bufsize 1M -flags +cgop -g 30 -hls_list_size 0 -hls_time 10 -f hls c:/users/name/documents/video/out/out2500_.m3u8​

See the above for an updated command that uses testrc2.mp4 as the input file.

[Carl Eugen Hoyos]

testsrc2 is a video filter that would allow to test your issue without needing your input file.

[ehollander]

I'm sorry, I don't understand. Is that a question, a statement? Is there something you want me to run? Please explain.

[Carl Eugen Hoyos]

Please provide a complete, actual command line starting as follows together with the complete, uncut console output to make this a valid ticket:

$ ffmpeg -f lavfi -i testsrc2 -c:v libx264 -profile:v ...

or, with audio:

$ ffmpeg -f lavfi -i testsrc2 -f lavfi -i sine -c:v libx264 -profile:v ...

[ehollander]

I'm done. I've given you everything you need to duplicate and understand the issue. If you choose not to fix it fine.

[Carl Eugen Hoyos]

Sorry, I did not understand the issue, that is why I asked you to provide the command line you tested together with the complete, uncut console output: This is what we require for every bug report, you have not provided it so far.
You can make reproducing the issue much easier for me by using (code blocks and) FFmpeg's internal input so that I don't have to try finding an input file with the same behaviour as your file.

Since you provided neither the console output (that would allow me to guess how the input file has to look like) nor the input file, the issue is difficult for me to reproduce as I hope you understand...

[Steven Liu]

Can you provide the problem? Maybe i misunderstand your mean.
Test step is bellow:
