HLS playback stops on DVD chapters with exactly 10 seconds , and probably if duration is multiples of that.
Seems that one more segment is created than required, and that segment is invalid:
# ll "/mnt/ffmpegfs/hls/1M/multimedia1/DVD/Musik/Summer Breeze/Summer Breeze (2010)/05. Chapter 001 [00-10.000].ts/"

Should be 1 segment actually.
If files have the same name, but a different extension, this creates duplicate output names:
Source:
America - A Horse With No Name-05.flac
America - A Horse With No Name-05.mp4
America - A Horse With No Name-05.mp3
Mount:
America - A Horse With No Name-05.webm
America - A Horse With No Name-05.webm
America - A Horse With No Name-05.webm
This is a problem, it is not clear which source file is used when opening such an entry.
The output files must have a unique name.
Problem:
The best solution would be to use the full source name with extension, e.g.
America - A Horse With No Name-05.flac.webm
America - A Horse With No Name-05.mp4.webm
America - A Horse With No Name-05.mp3.webm
This makes sure no duplicate entries are created. But this means that all output filenames change with this fix.
Video frames appear blurred especially if source is high res and target low res (e.g. Bluray HD to SD).

These errors are not passed to the accessing process (transcoding reported as success) but the files sometimes are garbled (e.g. "make check" fails).

After awhile of HLS streaming, ffmpegfs stops working spiiting "Too many open files" errors. Seems that some cache files never get closed (release2.x branch only).
Hi,
I hope I'm not too forward with this feature request. Since ffmpegfs currently outputs MP4, I don't think this would be too difficult to pull off, as MP4 and MOV are basically the same format.
A lot of editing software has very extensive QuickTime support but almost no AVI support and certainly no MKV support or other more obscure formats. I'd like to ask for a MOV mode where the filesystem is presented as virtual MOV files, with transcoding only enabled for those formats that can't be directly copied into MOV. For h.264 MP4 and MKV files for instance, transcoding is completely unnecessary as MOV supports wrapping h.264. For all other formats, it would be immensely powerful to use ffmpeg to transcode into ProRes as it is extremely fast and random-access.
Let me know what you think and thanks in advance.
I'm having an issue and I'm not sure if it's in the settings I've chosen or if it's a bug in ffmpegfs. When transcoding a flac file to opus the last few seconds of the audio file are missing. If I recopy the file immediately afterwards it results in a flawless transcode, so it only happens during the first transcode. The second copy pulls from the ffmpegfs cache I believe. My fstab entry is as follows:
ffmpegfs#/path/to/flacdir /path/to/opusdir fuse allow_other,ro,desttype=opus,audiobitrate=96K 0 0
Any suggestions would be greatly appreciated. If you need me to run additional test scenarios to debug this just let me know.
Below is the version I'm running (git commit 95993f0).

As an extra you could have different prores quality levels depending on the
source pixformat, for instance ProRes 4:4:4 if the source is RGB and
ProRes 4:2:2 if the source is YUV.
See #9.
Audio and video is out of sync on Android devices. Happens mostly on cellular connections. The delay is more than 500 - 1500 ms after a while.

Probably the start time must be set. Play file sources work.
There is no way to specify number of channels. In my use case I want to present mp3's as mono wav files. It would be nice to follow ffmpeg architecture and specify number of channels in general (1, 2, etc.)
Playback of some DVDs and Blurays looks garbled. There are artifacts, lost and repeated frames.

ffmpegfs should print nothing. The succes/fail message is printed by the OS.
Some chapters stop playing after 30 seconds, sometimes a few seconds early. Problem exists at least for half a year... There seems to be a problem extracting Bluray data.
This is a new issue that came up with the #43 fix:
The selected bitrate is not properly respected, resulting files with a 1MBit rate end up between 900KBit (would be OK) and 5MBit (far too large), depending on the source. If transcoded from high bitrates, e.g. blurays, the resulting file's rate will also be higher.
This seems to be a known problem, see https://stackoverflow.com/questions/11466184/setting-video-bit-rate-through-ffmpeg-api-is-ignored-for-libx264-codec. A possible fix is mentioned in the answer:
We need to set the pts for the decoded/resized frames before they are fed to encoder. The person who found the solution has gone through ffmpeg.c source and was able to figure this out. We need to first rescale the AVFrame's pts from the stream's time_base to the codec time_base to get a simple frame number (e.g. 1, 2, 3).
pic->pts = av_rescale_q(pic->pts, ost->time_base, ovCodecCtx->time_base); avcodec_encode_video2(ovCodecCtx, &newpkt, pic, &got_packet_ptr);And when we receive back the encoded packet from the libx264 codec, we need to rescale the pts and dts of the encoded video packet to the stream time base
newpkt.pts = av_rescale_q(newpkt.pts, ovCodecCtx->time_base, ost->time_base); newpkt.dts = av_rescale_q(newpkt.dts, ovCodecCtx->time_base, ost->time_base);
This fix is currently being evaluated. That's a FFmpeg API bug, if you ask me. But we'll have to bear with it anyway.
DVD transcoding sometimes stops in the middle of the chapter when the chapter consists of more than 1 cell. Playback stops a the end of the cell.
Normally, the end of the cell should be marked with SRI_END_OF_CELL which seems to be sometimes missing.
This is definetly a DVD authoring error, but should be tolerated in some way.
Add capability to create an HTTP Live Stream (also known as HLS).

After playing files for a while, sometimes the VME usage goes up to the machine limit, In this particular case the machine has 32 GB RAM with 13 GB free.
Never happens if the files are copied via Samba or directly, but only if played through a web server. Probably has to do with slow connections and time outs.
Related to the new thread pool feature:
"make check" sometimes hangs because a thread seems still to be running. Thread synchronisation must be checked and corrected.
Transcode crashes on a regular basis, creating a core file.

Apple Lossless is available via ffmpeg or other tools, it's pretty fast and great for iTunes users as it takes up less space than wav/aiff.
I would love to see wav support for this filesystem.
It would be immensely powerful to use ffmpeg to transcode into ProRes as it is extremely fast and random-access (reference #9).
Hi,
I understand that fixed bitrate makes it possible to calculate the maximum filesize on 'open', so:

The contents of the subdirectory listed earlier are reflected to the DVD root. If you list one or more other directories like the above, these will also appear as invalid files, causing FFmpegfs to lock up in the end.
When enable_ismv=1 is used, the resulting files do not play properly in VLC and other players. Strange enough they do play in Firefox, but get downloaded as a whole first (what is totally in contradiction what the format is supposed for).
what would it take to implement it?
like so:
# ls /storage/videos
video1.mp4
video2.mov
# ffmpegfs /storage/videos /mnt/ffmpegfs
# find /mnt/ffmpegfs
/mnt/ffmpegfs/video1.mp4/00001.png
/mnt/ffmpegfs/video1.mp4/00002.png
...
/mnt/ffmpegfs/video1.mov/00001.png

Add capability of Dynamic Adaptive Streaming over HTTP (DASH), also known as MPEG-DASH.

Looks like reencoding to the same file format as the source file is not supported? I'd like to convert the video resolution and bitrate of existing mp4 files to new mp4 files. Would it be possible to add support for this?
Database should automatically be updated to new structure if necessary
In case when the audio format of the source stream changes (e.g. from 2ch stereo to 6ch surround) ffmpeg crashes because the conversion is created in the beginning (for 2ch) but suddenly changes to something else.
Only with mp4 format the first 12 frames are simply grey, the next 2-3 frames are blurred. Happens with the H264 codec only, other codecs are not affected (mp4 and ts output format).
If under heavy use, memory fills up after a while. ffmpegfs needs to stopped and restarted. There seems to be a small memory leak.
When a file is accessed from a Windows machine for some reason the tail of the file is accessed directly, e.g. "read 14212 bytes from 693174272". These are exactly the last 14212 bytes of the file. The number differs from file to file, but it's always exactly the number of bytes remaining.
This happens on the very CreateFile() API call which is very odd. That call should only open a file but never attempt to read anything. This read access seems to time out after 10 seconds, and the file open operation succeeds.
That causes a big problem: ffmpeg is not notified of the interrupted read and continues to transcode until the data is available, i.e. in the above case up to 690 MB. Alas, because the open does not block the app tries to access the file, but Fuse will not satisfy any read requests before the pending read request has completed. This causes another timeout, the app will receive an EPERM (Permission denied).
Same strange thing happens when Windows Explorer reads a directory. It always access the file's tail. This is a performance hog.
When a file is opened for the first time, the resulting file has the wrong size:
When the file is accessed once more (read from cache), the size is correct.
i cloned the git repo, installed all the dependancies,
./autogen.sh
./configure
make
make install
everything ok... i mount the filesystem :
ffmpegfs --audiobitrate=256K --videobitrate=1.5M /mnt/BACKUP/Video/ /mnt/ffmpegfs -o allow_other,ro
but at the end... everything is the same in the 2 test directories...
There seems to be a regression from #11 : if the --desttype option is not an audio only format (ie: Opus, MP3, WAV, AIFF), all image files are converted.
It happens on the latest release (1.7) and the latest master, both built on Fedora 29.

When a directory is listed for the first time, all HLS segments have zero size. Seems that size prediction does not work as expected.
