[FFmpeg-user] MPD file creation using FFMpeg fails validation check
TL;DR DASH manifest file (mpd) created using ffmpeg fails the validation test and also fails to play. This is what I did: Step 1: Transcoded 2 video files with different resolution and bitrate (without audio stream) *ffmpeg -y -i file1.mp4 -c:v libvpx -vf scale=-2:270 -quality good -cpu-used 0 -b:v 400k -maxrate 400k -bufsize 400k -keyint_min 150 -g 150 -an -f webm -dash 1 file1-270.webmffmpeg -y -i file1.mp4 -c:v libvpx -vf scale=-2:360 -quality good -cpu-used 0 -b:v 1200k -maxrate 1200k -bufsize 1200k -keyint_min 150 -g 150 -an -f webm -dash 1 file1-360.webm* Step 2: Separately transcoded the audio stream *ffmpeg -y -i file1.mp4 -c:a libvorbis -b:a 128k -vn -f webm -dash 1 file1-audio.webm* Step 3: Created the Dash manifest file *ffmpeg -f webm_dash_manifest -i file1-270.webm -f webm_dash_manifest -i file1-360.webm -f webm_dash_manifest -i file1-audio.webm -c copy -map 0 -map 1 -map 2 -f webm_dash_manifest -adaptation_sets "id=0,streams=0,1 id=1,streams=2" file1.mpd* When I run this I get this warning "Output file is empty, nothing was encoded (check -ss / -t / -frames parameters if used)". However, the output file gets created. Now when I tried to run this file through DASH validation ( http://dashif.org/conformance.html) it said "MPD validation failed". Another validation tool (http://www-itec.uni-klu.ac.at/dash/?page_id=605) threw this error *Line:Col[8:57]:cvc-elt.1: Cannot find the declaration of element ‘MPD’.MPD validation not successful – DASH is not valid!* Regards, Rahul Prasad ___ ffmpeg-user mailing list ffmpeg-user@ffmpeg.org http://ffmpeg.org/mailman/listinfo/ffmpeg-user
Re: [FFmpeg-user] Configure error with Android NDK clang compiler
Carl Eugen, thanks for your reply. > I decided to install gas-preprocessor and this issue disappeared. For the sake of knowledge, I can't understand why I do need a gas-preprocessor to run the configure. If I create a file containing the same exact AS code run through "check_as" and run the same exact command to compile it (I took both from --logfile content), it actually works. Since there's some discrepancy between the command run by the configure script and the same exact command run manually on my terminal, I'm wondering how it could happen and if it's actually an issue related to the configure script. > Note that since compilation does not succeed for all files, I > suggest you use gcc for the time being. I manually patched the configure script to bypass "check_as" and I also realized the compilation fails. That's the next thing I will deeply look into.

[FFmpeg-user] ffmpeg Buffer - Delphi XE2 Question
Hi. I have a problem with the buffer and delay the image (MPEG-4) ( PTZ Camera) is about 2 seconds delay after PTZ moved positions always. How can set the video buffor to 0ms? PTZ Camera is in the LAN - no internet . When i change PTZ position the camera from browser then there is no delay. I connect to camera protocol RTSP, my link : rtsp://root:root@10.0.0.1:554/mpeg4/1/media.amp My camera model is AXIS 215 PTZ.

Re: [FFmpeg-user] Configure error with Android NDK clang compiler
I have not compiled FFMPEG for android using toolchain, however, I had a
tough time doing the same with opencv-JNI. This question, asked in
stackoverflow might help you.
http://stackoverflow.com/questions/34246265/opencv-ann-mlp-training-in-android
I read your ndk building procedure, don't you point Application.mk and
Android.mk files to your toolchain? I mean $NDK-PATH/ndk-build ? Are you
using gradle?

But, as I have written, by accident I passed an .iso file directly to ffmpeg and it works. It was a surprise for me. I didn't did a lot of tests, but I can extract images, convert some parts with seek, etc. I didn't check the time exactitude of those extractions. ffprobe reports the correct complete time of the DVD (as lsdvd). But, for at least one .iso, I have an error that I don't have when mounting the .iso manually. I have searched ffmpeg's code to check for .iso support but didn't found anything? But I don't know well the ffmpeg's code so my search is not optimal. I decided to continue to mount .iso manually and using dvd2concat for production.

[FFmpeg-user] Configure error with Android NDK clang compiler
I successfully build and run in production ffmpeg on Android (arm and x86)
compiled with Android NDK's gcc. Recently, Android deprecated gcc and is
pushing every dev to migrate to clang.
I'm getting some issues while compiling ffmpeg with Android NDK's clang and
this is the first one I encounter:
*GNU assembler not found, install/update gas-preprocessor*
Despite the message, looks that error is more subtle, because it fails
while running "check_as" but if I run the same exact check command on the
terminal, *it works*.
Below you can find the full instructions to reproduce it (it fixes with
--disable-asm but with gcc I'm able to compile with asm support).
Versions:
- ffmpeg 2.8.4
- Compile on OSX 10.9.5
*Download Android NDK*
You can download the Android NDK from here:
http://developer.android.com/ndk/downloads/index.html
*Install Android NDK*
Follow the installation instructions in the download and then set the
environment variable NDK_DIR to the directory where you extracted the NDK.
*Build NDK standalone toolchain*
Define an environment variable TOOLCHAIN_DIR with the full path of the
directory where the standalone toolchain should be installed. For example:
export TOOLCHAIN_DIR=/tmp/toolchain
Then build the toolchain:
${NDK_DIR}/build/tools/make-standalone-toolchain.sh \
--toolchain=arm-linux-androideabi-clang3.6 \
--platform=android-9 \
--install-dir=${TOOLCHAIN_DIR}

If I record my incoming MJPEG multipart/alternative HTTP stream with "-re -use_wallclock_as_timestamps 1", the timestamps look okay, though astonishingly quite strictly aligned to full seconds. (My stream can vary between 1 fps and 5 fps.) (Why is "-use_wallclock_as_timestamps" documented as an integer [0, INT_MAX-1] when it's use as a bool?

The following are console outputs from the client with and without the "*itsoffset*" option: == *1. **ffmpeg -y -i **http://192.168.0.11:8090/VIDEO_CAM1.mpg**-i **http://192.168.0.11:8090/AUDIO.mp2**-map 0:0 -map 0:0 -t 15 test.mp4 2> ffmpeg_client_without_itsoffset.txt* - without the "itsoffset" option - https://www.dropbox.com/s/hfo2newv7x4o12t/ffmpeg_client_without_itsoffset.txt?dl=0 ***2. **ffmpeg -y -i **http://192.168.0.11:8090/VIDEO_CAM1.mpg**-itsoffset 1.0 -i **http://192.168.0.11:8090/AUDIO.mp2**-map 0:0 -map 0:0 -t 15 test.mp4 2> ffmpeg_client_with_itsoffset.txt* - with the "itsoffset" option - https://www.dropbox.com/s/dirfkb3yndwtjni/ffmpeg_client_with_itsoffset.txt?dl=0 == I would also like to share my "*ffserver.conf*" and "*input ffmpeg commands*" == *1. ffserver.conf * https://www.dropbox.com/s/cf3kgyfimq6dgcr/ffserver.conf?dl=0* * *2. ffmpeg input commands (to ffserver)* https://www.dropbox.com/s/mdl5gufzuc59wmz/start.ffmpeg.sh?dl=0 == Hope this helps in getting further insight. Unfortunately, I suspect your http sources do not provide timestamps, so there is no easy solution;-( I see. The stream that seems to always start at *dts=0* is the audio stream. Please refer to the following outputs of ffprobe: == *1. ffprobe -i http://192.168.0.11:8090:AUDIO.mp2 -show_frames* - https://www.dropbox.com/s/xb5t88rc3vdyc0y/ffprobe_audio.txt?dl=0 - pkt_dts and pkt_pts always start at 0 *2. ffprobe -i http://192.168.0.11:8090:VIDEO_CAM1.mpg -show_frames* - https://www.dropbox.com/s/ywxgznv8xjbqozj/ffprobe_video.txt?dl=0 - pkt_dts and pkt_pts always start non-zero == I think that the solution is to add timestamp to the audio stream. But I already tried using the "*use_wallclock_as_timestamp*" option in ffmpeg audio feed. Nothing happened. Is there any other way to do this? I am very sorry for the inconvenience. I am not much of a programmer, but more of an enthusiast. I am using FFmpeg in my home for personal security and surveillance.
