  • Manual encoding into MPEG-TS

    4 juillet 2014, par Lane

    SO...

    I am trying to take a H264 Annex B byte stream video and encode it into MPEG-TS in pure Java. My goals is to create a minimal MPEG-TS, Single Program, valid stream and to not include any timing information information (PCR, PTS, DTS).

    I am currently at the point where my generated file can be passed to ffmpeg (ffmpeg -i myVideo.ts) and ffmpeg reports...

    [NULL @ 0x7f8103022600] start time is not set in estimate_timings_from_pts
    

    
Input #0, mpegts, from 'video.ts':
    
Duration: N/A, bitrate: N/A
    
Program 1 
    
  Stream #0:0[0x100]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709), 1280x720 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc

    ...it seems like this warning for start time is not a big deal... and ffmpeg is unable to determine how long the video is. If I create another mpeg-ts file from my video file (ffmpeg -i myVideo.ts -vcodec copy validVideo.ts) and run ffmpeg -i validVideo.ts I get...

    Input #0, mpegts, from 'video2.ts':
    
Duration: 00:00:11.61, start: 1.400000, bitrate: 3325 kb/s
    
Program 1 
    
  Metadata:
    
    service_name    : Service01
    
    service_provider: FFmpeg
    
  Stream #0:0[0x100]: Video: h264 (Main) ([27][0][0][0] / 0x001B), yuv420p(tv, bt709), 1280x720 [SAR 1:1 DAR 16:9], 29.97 fps, 29.97 tbr, 90k tbn, 59.94 tbc

    ...so you can see the timing information and bitrate is there and so is the metadata.

    My H264 video is comprised of only I and P Frames (with the SPS and PPS preceding the I Frame of course) and the way that I am creating my MPEG-TS stream is...

    1. Write a single PAT at the beginning of the file
    2. Write a single PMT at the beginning of the file
    3. Create TS and PES packets from SPS, PPS and I Frame (AUD NALs too, if this is required ?)
    4. Create TS and PES packets from P Frame (again, AUD NALs too, if required)
    5. For the last payload of either an I Frame or P Frame, add filler bytes to an adaptation field to make sure it fits into a full TS packet
    6. Repeat 3-5 for the entire file

    ...my PAT looks like this...

    4740 0010 0000 b00d 0001 c100 0000 01f0
    
002a b104 b2ff ffff ffff ffff ffff ffff

    ...and my PMT looks like this...

    4750 0010
    
0002 b012 0001 c100 00ff fff0 001b e100

ffff ffff ffff ffff

    ...notice after the c100 00, the "ff ff", f0... says that we are not using a PCR... Also notice that I have updated my CRC to reflect this change to the PMT. My first I Frame packet looks like...

    4741 0010 0000 01e0

    ...you’ll notice after the 01e0 0000, 8000 00 is the PES header extension where I specify no PTS / DTS and the remaining length is zero. My first P Frame packet looks like...

    ...and whenever an I Frame or P Frame is ending, I have a TS packet with an adaptation field like...

    4701 003c b000 ffff ffff ffff ffff ffff
    
ffff ffff ffff ffff ffff ffff ffff ffff

ffff ffff ffff ffff ffff ffff ffff ffff
    
ffff ffff ffff ffff ffff ffff

    ...where the first b0 bytes are the adaptation field stuffing bytes and the remaining ones are the final bytes of the I or P Frame. So as you can tell I can use ffmpeg and pass it my file to create a valid movie in any format. However, I need the file I create to be in the proper format and I cannot quite figure out what the last piece I am missing is. Any ideas ?

    2. Use funnels

    Creating conversion funnels gives you the big picture on whether your acquisition plans are paying off and where they may be falling short.

    Funnels feature

    If the ultimate goal of your site is to drive conversions, then each funnel can tell you how effectively you’re driving traffic through to your desired outcome.

    By integrating this with Visitor Profiles, you can view historic visitor profiles of any individual user at any stage of the conversion funnel. You see the full user journey at an individual level, including where they entered the funnel from and where they exited. Learn more

    How to amplify acquisition strategies with Funnels : Use conversion funnels to guide acquisition as you can tell which entry point is bringing the most success and which one needs more attention. Tailor your strategies to zone in on areas that have the most potential. You can identify where your visitors are encountering obstacles from the start, that are stopping them from progressing through their journey on your site.

    3. Study Visitor Profiles

    Visitor Profiles helps you understand visitors on a user-by-user basis, detailing each visitors’ history into a profile which summarises every visit, action and purchase made.

    Visitor Profiles feature

    Better understand :

    • Why your visitors viewed your website.

    • Why your returning visitors continue to view your website.

    • What specifically your visitors are looking for and whether they found it on your website.

    The benefit is being able to see how a combination of acquisition channels play a part in a single buyer’s journey.

    How Visitor Profiles helps with acquisition : By understanding the full behavioural patterns of any individual user coming through from external channels, you’ll see the path that led them to take action, where they may have gotten lost, and how engaged they are with your business over time. This gives you an indication of what kinds of visitors you’re attracting and helps you craft a buyer persona that more accurately reflects the audience most interested in you.

    4. Focus on SEO efforts

    Every acquisition plan needs a focus on maximising your Search Engine Optimization (SEO) efforts. When it comes to getting conclusive search engine referrer metrics, you need to be sure you’re getting ALL the insights to drive your SEO strategy.

    Integrate Google, Bing and Yahoo search consoles directly into your Matomo Analytics. This helps kickstart your acquisition goals as you rank highly for keywords that get the most traffic to your website.

    As another major SEO benefit, you can see how the most important search keywords to your business increased and decreased in ranking over time. 

    How to amplify acquisitions strategies with search engines and keywords : By staying on top of your competitors across ALL search engines, you may uncover traffic converting highly from one search engine, or find you could be losing traffic and business opportunities to your competitors across others.

    5. Look at the Multi Attribution feature

    Multi Attribution lets you measure the success of every touchpoint in the customer journey.

    Multi Attribution feature

    Accurately measure (and assign value to) channels where visitors first engaged with your business, where they came from after that, as well as the final channel they came from before purchasing your product or service.

    No longer falsely over-estimate any marketing channel and make smarter decisions when determining acquisition spend to accurately calculate the Customer Acquisition Cost (CAC). Learn more

    6. Set your Goals

    What are the acquisition goals you want to achieve the most ? The Goals feature lets you measure the most important metrics you need to grow your business.

    Goals feature

    Goals are crucial for building your marketing strategy and acquiring new customers. The more goals you track, the more you can learn about behavioural changes as you implement and modify paths that impact acquisition and conversions over time. You’ll understand which channels are converting the best for your business, which cities/countries are most popular, what devices will attract the most visitors and how engaged your visitors are before converting.

    This way you can see if your campaigns (SEO, PPC, signups, blogs etc.) or optimising efforts (A/B Testing, Funnels) have made an impact with the time and investment you have put in. Learn more

    7. Set Advanced Ecommence reporting

    If your website’s overall purpose is to generate revenue whether it be from an online store, asking for donations or from an online paid membership site ; the Ecommerce feature gives you comprehensive insights into your customers’ purchasing behaviours.

  • Audio clipping after amerge in FFmpeg

    23 avril 2021, par gooey_duck

    Hoping someone out there can help me with this audio issue I'm having using FFmpeg. I've written a bash script using FFmpeg that processes as source a broadcast quality ProRes (HQ) file with four mono tracks of audio. Source audio is LPCM 24-bit, 48kHz signed little endian, and I am exporting the same. Track 1 is full mix left, track 2 is full mix right, track 3 is music/FX left and track 4 is music/FX right. The script takes the source video and trims the video asset using in and out points from a sidecar XML. It also adds a custom slate at the head that uses a separate slate-only MOV file and is joined together via concat. Custom text is added to the slate via the drawtext filter and, finally, audio tracks 3 and 4 are removed and tracks 1 and 2 are merged together into a single stereo interleaved track using amerge.

    


    All of this, seemingly, works like a charm. The problem I'm noticing occurs when I run the resulting export through our in-house QC software. This software detects audio signal clipping at multiple points throughout the file created by FFmpeg. When I create this exact same file via Adobe Premiere or another transcode system, our QC does not detect any clipping. Our QC tools also do not detect any clipping in the source file. This leads me to believe that the clipping is being introduced either by FFmpeg or by my implementation of it. I've tried multiple additional filters within FFmpeg, including pan, amix, volume, etc., but nothing seems to help.

    


    Anyone have any ideas ? Pasting the relevant section of my script for reference :

    


    ffmpeg \
-ss "$hour":"$min":"$sec""$mil_fin" \
-t "$hour_minus":"$min_b":"$sec_b""$mil_fin_b" \
-i "$vid" \
-i "$elements_path"Slate_HD.mov \
-filter_complex \
"[0:a:0] [0:a:1] amerge=inputs=2 [stereo]; \

-timecode 09:59:30:00 \
-c:v prores_ks -profile:v 3 \
-c:a pcm_s24le \
-threads 3 \
"$output_name".mov


    


    Per suggestion, simplified audio only command line was run as follows :

    


    ffmpeg -i test.mov -i Slate_HD.mov -filter_complex "[0:a:0] [0:a:1] amerge=inputs=2 [stereo];[1:a][stereo]concat=n=2:a=1:v=0" -c:a pcm_s24le test_output.mov


    


    ...and the log from that command line :
