Have you tried that? All of our Samsungs have a dedicated input already named PC, but you can name as many as you like to PC.

Yes, but I need to learn about 2 things then: - How can I get information about the palette in an MKV-file? - How can I change such a palette?

Part of the problem seems to be controlling the palette to be used for rendering - you're getting three different results on three different players. As an (ugly) work-around, have you looked for a subtitle palette setting on your TV where the problem seems to be most annoying? And/or, if subtitles from other material display acceptably on your TV you could also compare palettes with those and work from there. > Here is the output of my test: > > --8<---cut here---start->8--- > peter@ws:/tmp/ffmpeg-tests> ~/tmp/FFmpeg/ffmpeg -y -i orig-dvbsub.ts - > map 0:0 -map 0:1 -map 0:2 -c:v libx264 -c:a copy -c:s dvdsub -palette > "0d00ee,ee450d,101010,eaeaea,0ce60b,ec14ed,ebff0b,0d617a,7b7b7b,d1d1 > d1,7b2a0e,0d950c,0f007b,cf0dec,cfa80c,7c127b" dvbsub2dvdsub.mkv ffmpeg > version N-97937-g82bf41f3ab Copyright (c) 2000-2020 the FFmpeg > developers > built with gcc 7 (SUSE Linux) > configuration: --enable-gpl --enable-libx264 > libavutil 56. 49.100 / 56. 49.100 > libavcodec 58. 87.101 / 58. 87.101 > libavformat58. 43.100 / 58. 43.100 > libavdevice58. 9.103 / 58. 9.103 > libavfilter 7. 83.100 / 7. 83.100 > libswscale 5. 6.101 / 5. 6.101 > libswresample 3. 6.100 / 3. 6.100 > libpostproc55. 6.100 / 55. 6.100 > [mpegts @ 0x298c840] PES packet size mismatch [mpegts @ 0x298c840] > Packet corrupt (stream = 2, dts = NOPTS). > Input #0, mpegts, from 'orig-dvbsub.ts': > Duration: 00:00:46.24, start: 3496.892811, bitrate: 3882 kb/s > Program 132 > Stream #0:0[0xa6]: Video: mpeg2video (Main) ([2][0][0][0] / 0x0002), > yuv420p(tv, top first), 720x576 [SAR 64:45 DAR 16:9], 25 fps, 25 tbr, 90k tbn, > 50 tbc > Side data: > cpb: bitrate max/min/avg: 800/0/0 buffer size: 1835008 vbv_delay: > N/A > Stream #0:1[0x80](deu): Audio: mp2 ([3][0][0][0] / 0x0003), 48000 Hz, > stereo, fltp, 192 kb/s > Stream #0:2[0x4b](deu): Subtitle: dvb_subtitle ([6][0][0][0] / 0x0006) > (hearing impaired) > Stream #0:3[0x44]: Data: bin_data ([6][0][0][0] / 0x0006) Stream mapping: > Stream #0:0 -> #0:0 (mpeg2video (native) -> h264 (libx264)) > Stream #0:1 -> #0:1 (copy) > Stream #0:2 -> #0:2 (dvb_subtitle (dvbsub) -> dvd_subtitle (dvdsub)) Press > [q] to stop, [?] for help > [libx264 @ 0x2ab9040] using SAR=64/45 > [libx264 @ 0x2ab9040] using cpu capabilities: MMX2 SSE2Fast SSSE3 SSE4.2 > AVX FMA3 BMI2 AVX2 > [libx264 @ 0x2ab9040] profile High, level 3.0, 4:2:0, 8-bit > [libx264 @ 0x2ab9040] 264 - core 160 - H.264/MPEG-4 AVC codec - Copyleft > 2003-2020 - http://www.videolan.org/x264.html - options: cabac=1 ref=3 > deblock=1:0:0 analyse=0x3:0x113 me=hex subme=7 psy=1 psy_rd=1.00:0.00 > mixed_ref=1 me_range=16 chroma_me=1 trellis=1 8x8dct=1 cqm=0 > deadzone=21,11 fast_pskip=1 chroma_qp_offset=-2 threads=18 > lookahead_threads=3 sliced_threads=0 nr=0 decimate=1 interlaced=0 > bluray_compat=0 constrained_intra=0 bframes=3 b_pyramid=2 b_adapt=1 > b_bias=0 direct=1 weightb=1 open_gop=0 weightp=2 keyint=250 > keyint_min=25 scenecut=40 intra_refresh=0 rc_lookahead=40 rc=crf > mbtree=1 crf=23.0 qcomp=0.60 qpmin=0 qpmax=69 qpstep=4 ip_ratio=1.40 > aq=1:1.00 Output #0, matroska, to 'dvbsub2dvdsub.mkv': > Metadata: > encoder : Lavf58.43.100 > Stream #0:0: Video: h264 (libx264) (H264 / 0x34363248), yuv420p, 720x576 > [SAR 64:45 DAR 16:9], q=-1--1, 25 fps, 1k tbn, 25 tbc > Metadata: > encoder : Lavc58.87.101 libx264 > Side data: > cpb: bitrate max/min/avg: 0/0/0 buffer size: 0 vbv_delay: N/A > Stream #0:1(deu): Audio: mp2 (P[0][0][0] / 0x0050), 48000 Hz, stereo, > fltp, > 192 kb/s > Stream #0:2(deu): Subtitle: dvd_subtitle (dvdsub) ([255][255][255][255] / > 0x) (hearing impaired) > Metadata: > encoder : Lavc58.87.101 dvdsub > [mpegts @ 0x298c840] Packet corrupt (stream = 0, dts = 315404353).e= > 318.3kbits/s speed=13.2x > [mpeg2video @ 0x2a96380] ac-tex damaged at 33 14 [mpeg2video @ > 0x2a96380] Warning MVs not available [mpeg2video @ 0x2a96380] > concealing 765 D

It is indeed possible to force a palette for dvd subtitles but only on decoding because many sources miss the palette, your command line should produce an output file with dvdsub palette. > This is how I create the video: > > ffmpeg -i input.ts -map 0:0 -map 0:1 -map 0:2 -c:v libx264 -c:a copy >-c:s dvdsub output.mkv Complete, uncut console output missing. > This looks nice with VLC: http://pmrb.free.fr/tmp/ffmpeg-test/vlc.jpg > But very ugly with a Samsung TV: Looks like an issue of the Samsung TV but feel free to compare with other players.

[FFmpeg-user] how to control quality of subtitles
Hi, I would like to learn, how to control the quality of the displayed subtitles. This is how I create the video: ffmpeg -i input.ts -map 0:0 -map 0:1 -map 0:2 -c:v libx264 -c:a copy -c:s dvdsub output.mkv This looks nice with VLC: http://pmrb.free.fr/tmp/ffmpeg-test/vlc.jpg But very ugly with a Samsung TV: http://pmrb.free.fr/tmp/ffmpeg-test/samsung.jpg How could I get nice looking subtitles on this kind of Samsung TV please? Thanks in advance for any hints, -- Peter ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org https://ffmpeg.org/mailman/listinfo/ffmpeg-user To unsubscribe, visit link above, or email ffmpeg-user-requ...@ffmpeg.org with subject "unsubscribe".
