How to add #EXT-X-PART:DURATION=0.200,URI="filePart271.0.mp4" into .m3u8 in ffmpeg ? [closed]
11 août 2023, par palakSo my question is : How do I add #EXT-X-PART:DURATION=0.200,URI="filePart271.0.mp4" to my HLS m3u8 playlist file using FFmpeg ?


And the error i am receiving is Unrecognized option 'hls_part_flags'.
Error splitting the argument list : Option not found.


as well as Unrecognized option 'hls_part_target'.
Error splitting the argument list : Option not found.


Currently my FFmpeg command is the following :
ffmpeg -f lavfi -t 16 -i anullsrc -f lavfi -i testsrc=size=1280x720:rate=30 -c:v libx264 -c:a aac -t 16 -hls_time 4 -hls_playlist_type vod -hls_segment_type fmp4 -start_number 266 -hls_flags single_file -master_pl_name master.m3u8 -var_stream_map "v:0,a:0" -hls_segment_filename 'fileSequence%v.mp4' -hls_fmp4_init_filename 'city.mp4' -hls_base_url './' -hls_segment_filename 'filePart%v.%04d.mp4' -hls_part_flags '+independent' -hls_part_target 0.200 output.m3u8


My expectation is that, How do I add #EXT-X-PART:DURATION=0.200,URI="filePart271.0.mp4" to my HLS m3u8 playlist file using FFmpeg ?

How to save srt file with a video to be part of the video ?
14 septembre 2023, par abdallah mostafaI've an application that generate srt file for a video with AI but I want to save the video to user's storage with the srt subtitle burned on the video not just embedded.


this is the response form the API


"fotmated_subtitle": [
 {
 "display_text": "You know those cat are memes that everybody uses in their videos and the TV movie clips that people use.",
 "interval": [
 "0:00:00.000",
 "0:00:04.000"
 ]
 },
 {
 "display_text": "Well, who are the four best free websites to find a move?",
 "interval": [
 "0:00:04.000",
 "0:00:06.240"
 ]
 }
 ]


I could add this as a widget over the video that would change accourding to intervals.
I want to know How to save that video with the subtitle


Future<void> saveSubtitle() async {
 emit(ExportSubtitleLoading());
 String subtitleFilter = "";
 for (var subtitle in subtitles!.fotmatedSubtitle!) {
 String startTime = subtitle.interval![0];
 String endTime = subtitle.interval![1];
 String text = subtitle.displayText!;
 subtitleFilter +=
 "drawtext=text='$text':enable='between(t,$startTime,$endTime)':x=(w-text_w)/2:y=h-30:fontsize=24:fontcolor=white,";
 }

 final dir = await getTemporaryDirectory();
 String outputPath = '${dir.path}/ex_vid.mp4';
 final arguments = [
 '-i',
 inputFile,
 '-vf',
 subtitleFilter,
 '-c:v',
 'libx264',
 '-c:a',
 'copy',
 outputPath
 ];
 (arguments.join(' ')).logger;
 '=============='.logger;
 await FFmpegKit.execute(arguments.join(' ')).then((session) async {
 final returnCode = await session.getReturnCode();

 if (ReturnCode.isSuccess(returnCode)) {
 ('The Converstion is Success').logger;
 emit(ExportSubtitleSuccess());
 } else if (ReturnCode.isCancel(returnCode)) {
 // CANCEL
 ('The Converstion is Cancelled').logger;
 } else {
 emit(ExportSubtitleerror());
 ('The Converstion Have an Error').logger;
 }
 });
 }
</void>

I've tested this method but still does not worked


here is the full command


String command =
 "-y -i /data/user/0/com.amaa.aistudio/cache/file_picker/Blink-96bdc94a-17df-4f64-b560-90811a44c4f8-Original.mp4 -vf \"drawtext=text='You know those cat are memes that everybody uses in their videos and the TV movie clips that people use.':enable='between(t,0,4.000)':x=(w-text_w)/2:y=h-30:fontsize=24:fontcolor=white,drawtext=text='Well, who are the four best free websites to find a move?':enable='between(t,4.000,6.240)':x=(w-text_w)/2:y=h-30:fontsize=24:fontcolor=white\" -c:v libx264 -c:a copy /data/user/0/com.amaa.aistudio/cache/ex_vid.mp4";

transcoding part anexB bitstream
30 octobre 2023, par bot.top.popI'm using gohlslib for converting RTMP to HLS, this library gives me HLS and LHS with the transmuxing feature where each segment is of 2s.


But I also want to support the ABR, the flow with this is NALUs are packed in either AVCC or AnexB format and stored in fmp4 parts. []parts make one segment.


I was thinking if I could be able to transcode this anexB or AVCC stream format after its packed into fmp4.
I tried to check what's packed in parts and stored the output as .h264 file.


The first part of a segment has NALUs in this order
SPSPPSSPSPPSslice of IDRslice of non-IDR...
but the later parts that are created don't have it.

Only the 1st part of every segment has
SPSPPSSPSPPSslice of IDR.

I may be wrong to say that this is what raw .h264 content.


My question is, is it even possible to transcode such part files using
GoorCXXwhile maintaining same PTS and DTS of the transmuxed parts/segment
