Merge Videos

Hi

I was following this issue but I am still having issues merging 2 video files My code is as follows `@Test public void test() throws IOException { String introVideoFile=“C:\development\vid\final\tmpIntro_3.mp4”; String videoContentFile=“C:\development\vid\final\tmpContent_3.mp4”;

	VideoPropertiesVO videoPropertiesVO = new VideoPropertiesVO();
	videoPropertiesVO.setOutputVideoFileLocation("C:\\development\\vid\\final\\output.mp4");
	boolean concatResult = concatVideos(videoPropertiesVO, introVideoFile, videoContentFile);
	System.out.println("concatResult:" + concatResult);
}


private static boolean concatVideos(VideoPropertiesVO videoPropertiesVO, String introVideoFile, String videoContentFile)
		throws IOException {
	System.out.println("introVideoFile:" + introVideoFile);
	System.out.println("videoContentFile:" + videoContentFile);

	FFmpeg ffmpeg = new FFmpeg(Constants.FFMPEG_EXE_PATH);;
	FFprobe ffprobe= new FFprobe(Constants.FFPROBE_EXE_PATH);	
	
	Path listOfFiles = null;
	try {
		Path intro = Paths.get(introVideoFile);
		Path content = Paths.get(videoContentFile);

		Path[] files = new Path[2];
		files[0] = intro;
		files[1] = content;

		String filesStrings = List(files).map(f -> f.toAbsolutePath().toString()).map(p -> "file '" + p + "'")
				.mkString(System.getProperty("line.separator"));

		listOfFiles = Files.createTempFile(intro.getParent(), "ffmpeg-list-", ".txt");
		Files.write(listOfFiles, filesStrings.getBytes());

		FFmpegBuilder builder = new FFmpegBuilder()
				.setInput(listOfFiles.toAbsolutePath().toString())
				.setFormat(FORMAT_CONCAT).addExtraArgs("-safe")
				.addOutput(videoPropertiesVO.getOutputVideoFileLocation())
				.setAudioCodec(CODEC_COPY)
				.setVideoCodec(CODEC_COPY).done();
		builder.setVerbosity(Verbosity.DEBUG);

		FFmpegExecutor fFmpegExecutor = new FFmpegExecutor(ffmpeg, ffprobe);

		fFmpegExecutor.createJob(builder).run();

	} catch (IOException e) {
		System.out.println("Error during Ffmpeg conversion: Exception:" + e);
	} finally {
		Path finalListOfFiles = listOfFiles;
		if (nonNull(listOfFiles)) {
			Try(() -> Files.deleteIfExists(finalListOfFiles));
		}
	}
	return true;
}`

I can verify that all files do exist. The output I get is as follows introVideoFile:C:\development\vid\final\tmpIntro_3.mp4 videoContentFile:C:\development\vid\final\tmpContent_3.mp4 ffmpeg version N-89343-g83ecdc9a92 Copyright (c) 2000-2017 the FFmpeg developers built with gcc 7.2.0 (GCC) configuration: --enable-gpl --enable-version3 --enable-sdl2 --enable-bzlib --enable-fontconfig --enable-gnutls --enable-iconv --enable-libass --enable-libbluray --enable-libfreetype --enable-libmp3lame --enable-libopenjpeg --enable-libopus --enable-libshine --enable-libsnappy --enable-libsoxr --enable-libtheora --enable-libtwolame --enable-libvpx --enable-libwavpack --enable-libwebp --enable-libx264 --enable-libx265 --enable-libxml2 --enable-libzimg --enable-lzma --enable-zlib --enable-gmp --enable-libvidstab --enable-libvorbis --enable-cuda --enable-cuvid --enable-d3d11va --enable-nvenc --enable-dxva2 --enable-avisynth --enable-libmfx libavutil 56. 4.100 / 56. 4.100 libavcodec 58. 6.102 / 58. 6.102 libavformat 58. 2.103 / 58. 2.103 libavdevice 58. 0.100 / 58. 0.100 libavfilter 7. 5.100 / 7. 5.100 libswscale 5. 0.101 / 5. 0.101 libswresample 3. 0.101 / 3. 0.101 libpostproc 55. 0.100 / 55. 0.100 Splitting the commandline.

The main error is [NULL @ 000002164fc2ab60] Requested output format ‘concat’ is not a suitable output format

Could someone please help to validate what may be the issue here?

Thank you Damien

I got it working! using .addExtraArgs(“-safe”, “0”)

[clicit]

Same problem here, anyone got this working? @HadesDX maybe? When I start ffmpeg manually from the command with exactly the same parameters, there is no problem.

Thanks!

I got it working now: I was using relative paths in the TXT file. Using absolute paths there solved the problem!
