See also our earlier Toolbox post Extract Frame to Project. Scan type, store method : Interleaved fields 1 2 ffmpeg -i test.mp4 -vf fps1/60 thumb04d.png Output one image every 10 minutes: 1 ffmpeg -i test.mp4 -vf fps1/600 thumb04d. Original network name : 1 degree W (Telenor)įormat settings, picture structure : Frame ![]() The problem with this is that dumping frames and writing upscaled frames write a lot of data. Re-encode into video using the upscaled frames. Upscale each frame using the AI program and write/save the finished frame. Post a MediaInfo report on the TS file GeneralĬomplete name : D:\ ffmpeg\bin\film 01.ts Dump frames of video into a sequence of png files. The command I have tried that gets me closest is this: ffmpeg -i Wings1.mp4 -ss 00:00:22 -i Wings1.mp4 -ss 00:01:58 -frames:v 2 Wings/Journal2d. What I want to do is extract the frames at the specific timecodes to a folder of my choice. Can't write packet with unknown timestampĪv_interleaved_write_frame(): Invalid argument The frames do not come at specific intervals but I have determined the timecode for the relevant frames. ![]() Fix your code to set the timestamps properly This is deprecated and will stop working in the future. If we want to extract just a single frame (-vframes 1) from the video ( Yosemite) into an image file, we do: ss: set the start time offset. Stream #0:2(dan): Subtitle: dvd_subtitle (default)Įverything is fine but it stops at 45:00 (the original file is 01:08:47)Įrror: Timestamps are unset in a packet for stream 0. Why?įfmpeg -i film.ts -map 0:0 -map 0:1 -map 0:3 -vcodec copy -acodec copy -scodec dvdsub film.mkvI got this results Could not find codec parameters for stream 6 (Unknown: none ( / 0x000B)): unknown codec ![]() Could not find codec parameters for stream 5 (Unknown: none ( / 0x0005)): unknown codecĬonsider increasing the value for the 'analyzeduration' and 'probesize' options start time for stream 4 is not set in estimate_timings_from_pts ![]() start time for stream 3 is not set in estimate_timings_from_pts number of reference frames (0 4) exceeds max (3 probably corrupt input), discarding one SPS unavailable in decode_picture_timing The full eror discription is a "little" long :
