It’s a video container similar to MOV and AVI, except it can hold an infinite amount of audio, video, and subtitle tracks (like SRT or USF). Matroska is connected with the following file extensions:Ī Matroska Video file is one that has the.MKV extension. The file format is similar to MP4 and other media containers and is totally open source. Matroska Multimedia Container is a file format that may hold an unlimited number of video, audio, picture, or subtitle tracks in a single file.
#Ffmpeg mkv to mp4 container how to
I assume that I'll need to specify input and output codecs specifically, along with things like bitrate, or aspect ratio but this is where I come unstuck. I have tried a few permutations of my script, such as: ffmpeg -i "$file" "$noextension"Īnd ffmpeg -y -i "$file" -vcodec mpeg4 -acodec libfaac "$noextension"īut those both give me the following error: Error while opening encoder for output stream #0.0 - maybe incorrect parameters such as bit_rate, rate, width or height I've read through but the error message from ffmpeg doesn't seem very helpful, and resources are sparse at best when it comes to running this stuff on a Synology Box. The XBox support website gives details on supported file types, with mp4 included in the H.264 standard: Stream #0.1(eng): Audio: libfaac, 48000 Hz, stereo (default)Īv_interleaved_write_frame(): Invalid data found when processing input and then a list of output chapter start and end times and then. and then a list of input chapter start and end times and then. Estimating duration from bitrate, this may be inaccurate
The following is an example of the output for a failed run: ffmpeg version UNKNOWN, Copyright (c) 2000-2011 the FFmpeg developersĬonfiguration: -prefix=/usr/syno -arch=i686 -target-os=linux -cross-prefix=/usr/local/i686-linux-gnu/bin/i686-linux-gnu-enable-cross-compile -enable-optimizations -disable-yasm -disable-altivec -enable-pic -enable-shared -disable-static -disable-swscale-alpha -disable-ffserver -disable-ffplay -enable-libmp3lame -enable-libfaac -enable-nonfree -enable-version3 -enable-libopencore-amrnb -enable-libopencore-amrwb -disable-decoder=amrnb -disable-indev=alsa -disable-outdev=alsa -disable-encoder=dca -disable-encoder=ac3 -disable-encoder=ac3_fixed -disable-encoder=ac3_float -disable-encoder=eac3 -disable-decoder=dca -disable-decoder=eac3 -disable-decoder=truehd -cc=/usr/local/i686-linux-gnu/bin/i686-linux-gnu-ccache-gcc This has worked for several of my files, but there are a number for which this does not work. Which, as I understand it, simply copies the audio and video components within the mkv container, and inserts them into a new mp4 container. I'm very rusty on Linux and new to transcoding, but the script I currently have is the following: #!/bin/bashįfmpeg -y -i "$file" -vcodec copy -acodec copy "$noextension" I use Handbrake on my laptop, but I would rather have this happen directly on my NAS. mkv movies which I would like to convert/transcode to mp4 files, so that I can stream them directly to my XBox 360. I recently purchased a Synology Diskstation DS412+, and I have a number of.
