Problem with interlaced x265 encoding and muxing to m2ts

[Selur]

I created a video stream using:

ffmpeg -y -loglevel fatal -noautorotate -nostdin -threads 8 -i "G:\TestClips&Co\files\interlaceAndTelecineSamples\interlaced\bff.m2v" -map 0:0 -an -sn -vf zscale=rangein=tv:range=tv -pix_fmt yuv420p10le -strict -1 -vsync 0 -top 0 -f yuv4mpegpipe - | x265 --input - --fps 30000/1001 --output-depth 10 --y4m --profile main10 --crf 18.00 --interlace bff --range limited --colormatrix bt470bg --sar 8:9 --output "J:\tmp\2023-11-24@15_37_21_4710_01.265"

(attached bff.m2v and 2023-11-24@15_37_21_4710_01.265)
not I want to multiplex it using:

ffmpeg -y  -r 30000/1001 -fflags +genpts -i "J:\tmp\2023-11-24@15_37_21_4710_01.265" -top 0 -metadata encoding_tool="Hybrid 2023.11.24.1" -c:0 copy -map 0:0  -bsf:v hevc_mp4toannexb -tag:v hvc1  -aspect 20:15 -r 30000/1001 -fflags +genpts -f mpegts "G:\Output\bff.m2ts"

but end up with:

Input #0, hevc, from 'J:\tmp\2023-11-24@15_18_05_5010_01.265':

the x265 version I use is:

x265 [info]: HEVC encoder version 3.5+111-c40c3d799
x265 [info]: build info [Windows][GCC 13.2.0][64 bit] 8bit+10bit+12bit
x265 [info]: using cpu capabilities: MMX2 SSE2Fast LZCNT SSSE3 SSE4.2 AVX FMA3 BMI2 AV

A few things bug me:
a. that it's not working
b. that the created video is detected as 'top first' and '25 fps, 29.97 tbr'.

Does anyone know how to fix these to issues?

Your bff.m2v:

Stream #0:0: Video: mpeg2video (Main), yuv420p(tv, bottom first), 720x480 [SAR 8:9 DAR 4:3], 25 fps, 29.97 tbr, 1200k tbn

no duration info

the same, in a mpg container:

Stream #0:0[0x1e0]: Video: mpeg2video (Main), yuv420p(tv, bottom first), 720x480 [SAR 8:9 DAR 4:3], 29.97 fps, 29.97 tbr, 90k tbn

duration 05.01

For the muxing of the .265 stream you have to add:

-bsf:v setts=ts=STARTPTS+N/TB_OUT/29.97

to your commandline.

That seems to help with:

[mpegts @ 000002cecd3a87c0] Timestamps are unset in a packet for stream 0. This is deprecated and will stop working in the future. Fix your code to set the timestamps properly
[mpegts @ 000002cecd3a87c0] first pts and dts value must be set

but using:

ffmpeg -y  -r 30000/1001 -fflags +genpts -i "J:\tmp\2023-11-24@15_37_21_4710_01.265" -top 0 -metadata encoding_tool="Hybrid 2023.11.24.1" -c:0 copy -map 0:0  -bsf:v hevc_mp4toannexb,setts=ts=STARTPTS+N/TB_OUT/29.97  -tag:v hvc1  -aspect 20:15 -r 30000/1001 -fflags +genpts -f mpegts "G:\Output\bff.m2ts"

gives me:

My commandline:

FFmpeg.exe -y -fflags +genpts -i 2023-11-24@15_37_21_4710_01_TSF.mp4 -map 0:0 -c:v copy 2023-11-24@15_37_21_4710_01_TSF_muxed.m2ts

converted first to mp4 with:

Thanks, but strangely, that does not work here:

ffmpeg -y -r 30000/1001 -i "J:\tmp\2023-11-24@15_37_21_4710_01.265" -map 0:0 -c:v copy -bsf:v setts=ts=STARTPTS+N/TB_OUT/29.97 "G:\Output\bff.mp4"

fails with:

will try other ffmpeg versions, maybe its a bug in 'ffmpeg version N-112813-g1c3b13b9f7-gc961ac4b0c+1'.

Hmm,.. using:

ffmpeg -y  -r 30000/1001 -fflags +genpts -i "J:\tmp\2023-11-24@15_37_21_4710_01.265" -top 0 -metadata encoding_tool="Hybrid 2023.11.24.1" -c:0 copy -map 0:0  -bsf:v hevc_mp4toannexb -tag:v hvc1  -aspect 20:15 -r 30000/1001 "G:\Output\bff.mp4"

creates an mp4:

Thanks.
Creating an intermedia file makes it unpractical for me, but it's good to know.
Do you have an idea to get ffmpeg to flag it as bff not tff?
