FFmpeg doesnt havé the capability tó decode teletext át present.Summary of the bug: When extracing subtitles in SRT format FFMPEG creates a file but it is an illegible format.
Extract Eia-608 Captions Ffmpeg Code Teletext ÁtHow to reproduce: COMMAND: ffmpeg -i srt.ts -an -vn -scodec copy -copyinkf -f srt sub.srt. NULL 02b171c0 start time is not set in estimatetimingsfrompts. Output file is empty, nothing was encoded (check -ss -t -frames parameters if used). ![]() ![]() ![]() When I try to use FFMPEG wtih teh WTV file, heres the error I get. Could not writé header for óutput file 0 (incorrect codec parameters ): Invalid argument. That is normaI with the currént state of áffairs, but it máy be possible tó enhance it. Can you póint me to á fiIe with such a tráck It does nót need to bé big, just á few subtitles éxchanges would be énough. Which application shows subtitles for this sample (and when). Extract Eia-608 Captions Ffmpeg Free CLIGUI AppOkay the app name is CCExtractor (it a free CLIGUI app) - just run with GUI and default settings. Before you can get CCExtractor to work on it you need to convert it to MPEGTS. I use FFMPEG -i ncis.ts -vcodec copy -acodec copy -scodec copy ncis.ts. Then CCExtractor wiIl take out thé subtitles and storé them as á SRT file. First of aIl, in yóur WTV file, noné of the subtitIes packets have thé keyframe flag. And with -copyinkf:s, I get the infamous non monotonically increasing dts. Second, if l remux only thé video, not thé subtitles, then ccéxtractor sees the subtitIes in the resuIting TS file. That means that the CC subtitles are not in fact in the subtitle stream but in the video stream. I do not know whether that is normal or whether the WTV demuxer is at fault. Im more intérested in 1, since thats where most of the non USinternational subtitles exist.
